breech presentation symptoms

Pregnancy Classes

Breech Births

In the last weeks of pregnancy, a baby usually moves so his or her head is positioned to come out of the vagina first during birth. This is called a vertex presentation. A breech presentation occurs when the baby’s buttocks, feet, or both are positioned to come out first during birth. This happens in 3–4% of full-term births.

What are the different types of breech birth presentations?

Complete breech: Here, the buttocks are pointing downward with the legs folded at the knees and feet near the buttocks.
Frank breech: In this position, the baby’s buttocks are aimed at the birth canal with its legs sticking straight up in front of his or her body and the feet near the head.
Footling breech: In this position, one or both of the baby’s feet point downward and will deliver before the rest of the body.

What causes a breech presentation?

The causes of breech presentations are not fully understood. However, the data show that breech birth is more common when:

You have been pregnant before
In pregnancies of multiples
When there is a history of premature delivery
When the uterus has too much or too little amniotic fluid
When there is an abnormally shaped uterus or a uterus with abnormal growths, such as fibroids
The placenta covers all or part of the opening of the uterus placenta previa

How is a breech presentation diagnosed?

A few weeks prior to the due date, the health care provider will place her hands on the mother’s lower abdomen to locate the baby’s head, back, and buttocks. If it appears that the baby might be in a breech position, they can use ultrasound or pelvic exam to confirm the position. Special x-rays can also be used to determine the baby’s position and the size of the pelvis to determine if a vaginal delivery of a breech baby can be safely attempted.

Can a breech presentation mean something is wrong?

Even though most breech babies are born healthy, there is a slightly elevated risk for certain problems. Birth defects are slightly more common in breech babies and the defect might be the reason that the baby failed to move into the right position prior to delivery.

Can a breech presentation be changed?

It is preferable to try to turn a breech baby between the 32nd and 37th weeks of pregnancy . The methods of turning a baby will vary and the success rate for each method can also vary. It is best to discuss the options with the health care provider to see which method she recommends.

Medical Techniques

External Cephalic Version (EVC) is a non-surgical technique to move the baby in the uterus. In this procedure, a medication is given to help relax the uterus. There might also be the use of an ultrasound to determine the position of the baby, the location of the placenta and the amount of amniotic fluid in the uterus.

Gentle pushing on the lower abdomen can turn the baby into the head-down position. Throughout the external version the baby’s heartbeat will be closely monitored so that if a problem develops, the health care provider will immediately stop the procedure. ECV usually is done near a delivery room so if a problem occurs, a cesarean delivery can be performed quickly. The external version has a high success rate and can be considered if you have had a previous cesarean delivery.

ECV will not be tried if:

You are carrying more than one fetus
There are concerns about the health of the fetus
You have certain abnormalities of the reproductive system
The placenta is in the wrong place
The placenta has come away from the wall of the uterus ( placental abruption )

Complications of EVC include:

Prelabor rupture of membranes
Changes in the fetus’s heart rate
Placental abruption
Preterm labor

Vaginal delivery versus cesarean for breech birth?

Most health care providers do not believe in attempting a vaginal delivery for a breech position. However, some will delay making a final decision until the woman is in labor. The following conditions are considered necessary in order to attempt a vaginal birth:

The baby is full-term and in the frank breech presentation
The baby does not show signs of distress while its heart rate is closely monitored.
The process of labor is smooth and steady with the cervix widening as the baby descends.
The health care provider estimates that the baby is not too big or the mother’s pelvis too narrow for the baby to pass safely through the birth canal.
Anesthesia is available and a cesarean delivery possible on short notice

What are the risks and complications of a vaginal delivery?

In a breech birth, the baby’s head is the last part of its body to emerge making it more difficult to ease it through the birth canal. Sometimes forceps are used to guide the baby’s head out of the birth canal. Another potential problem is cord prolapse . In this situation the umbilical cord is squeezed as the baby moves toward the birth canal, thus slowing the baby’s supply of oxygen and blood. In a vaginal breech delivery, electronic fetal monitoring will be used to monitor the baby’s heartbeat throughout the course of labor. Cesarean delivery may be an option if signs develop that the baby may be in distress.

When is a cesarean delivery used with a breech presentation?

Most health care providers recommend a cesarean delivery for all babies in a breech position, especially babies that are premature. Since premature babies are small and more fragile, and because the head of a premature baby is relatively larger in proportion to its body, the baby is unlikely to stretch the cervix as much as a full-term baby. This means that there might be less room for the head to emerge.

Terms that describe the fetus in relation to the uterus, cervix, and maternal pelvis are

Fetal presentation: Fetal part that overlies the maternal pelvic inlet; vertex (cephalic), face, brow, breech, shoulder, funic (umbilical cord), or compound (more than one part, eg, shoulder and hand)

Fetal position: Relation of the presenting part to an anatomic axis; for transverse presentation, occiput anterior, occiput posterior, occiput transverse

Fetal lie: Relation of the fetus to the long axis of the uterus; longitudinal, oblique, or transverse

Normal fetal lie is longitudinal, normal presentation is vertex, and occiput anterior is the most common position.

Abnormal fetal lie, presentation, or position may occur with

Fetopelvic disproportion (fetus too large for the pelvic inlet)

Fetal congenital anomalies

Uterine structural abnormalities (eg, fibroids, synechiae)

Multiple gestation

Several common types of abnormal lie or presentation are discussed here.

Transverse lie

Fetal position is transverse, with the fetal long axis oblique or perpendicular rather than parallel to the maternal long axis. Transverse lie is often accompanied by shoulder presentation, which requires cesarean delivery.

Breech presentation

There are several types of breech presentation.

Frank breech: The fetal hips are flexed, and the knees extended (pike position).

Complete breech: The fetus seems to be sitting with hips and knees flexed.

Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

Types of breech presentations

Breech presentation makes delivery difficult ,primarily because the presenting part is a poor dilating wedge. Having a poor dilating wedge can lead to incomplete cervical dilation, because the presenting part is narrower than the head that follows. The head, which is the part with the largest diameter, can then be trapped during delivery.

Additionally, the trapped fetal head can compress the umbilical cord if the fetal umbilicus is visible at the introitus, particularly in primiparas whose pelvic tissues have not been dilated by previous deliveries. Umbilical cord compression may cause fetal hypoxemia.

Predisposing factors for breech presentation include

Preterm labor Preterm Labor Labor (regular uterine contractions resulting in cervical change) that begins before 37 weeks gestation is considered preterm. Risk factors include prelabor rupture of membranes, uterine abnormalities... read more

Multiple gestation Multifetal Pregnancy Multifetal pregnancy is presence of > 1 fetus in the uterus. Multifetal (multiple) pregnancy occurs in up to 1 of 30 deliveries. Risk factors for multiple pregnancy include Ovarian stimulation... read more

Uterine abnormalities

Fetal anomalies

If delivery is vaginal, breech presentation may increase risk of

Umbilical cord prolapse

Perinatal death

It is best to detect abnormal fetal lie or presentation before delivery. During routine prenatal care, clinicians assess fetal lie and presentation with physical examination in the late third trimester. Ultrasonography can also be done. If breech presentation is detected, external cephalic version can sometimes move the fetus to vertex presentation before labor, usually at 37 or 38 weeks. This technique involves gently pressing on the maternal abdomen to reposition the fetus. A dose of a short-acting tocolytic ( terbutaline 0.25 mg subcutaneously) may help. The success rate is about 50 to 75%. For persistent abnormal lie or presentation, cesarean delivery is usually done at 39 weeks or when the woman presents in labor.

Face or brow presentation

In face presentation, the head is hyperextended, and position is designated by the position of the chin (mentum). When the chin is posterior, the head is less likely to rotate and less likely to deliver vaginally, necessitating cesarean delivery.

Brow presentation usually converts spontaneously to vertex or face presentation.

Occiput posterior position

The most common abnormal position is occiput posterior.

The fetal neck is usually somewhat deflexed; thus, a larger diameter of the head must pass through the pelvis.

Progress may arrest in the second phase of labor.

Position and Presentation of the Fetus

If a fetus is in the occiput posterior position, operative vaginal delivery or cesarean delivery is often required.

In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord.

For breech presentation, usually do cesarean delivery at 39 weeks or during labor, but external cephalic version is sometimes successful before labor, usually at 37 or 38 weeks.

What Causes Breech Presentation?

What Is Breech Presentation?

Types of breech presentation, what causes a breech baby, can you turn a breech baby, how are breech babies delivered.

FatCamera/Getty Images

Toward the end of pregnancy, your baby will start to get into position for delivery, with their head pointed down toward the vagina. This is otherwise known as vertex presentation. However, some babies turn inside the womb so that their feet or buttocks are poised to be delivered first, which is commonly referred to as breech presentation, or a breech baby.

As you near the end of your pregnancy journey, an OB-GYN or health care provider will check your baby's positioning. You might find yourself wondering: What causes breech presentation? Are there risks involved? And how are breech babies delivered? We turned to experts and research to answer some of the most common questions surrounding breech presentation, along with what causes this positioning in the first place.

During your pregnancy, your baby constantly moves around the uterus. Indeed, most babies do somersaults up until the 36th week of pregnancy , when they pick their final position in the womb, says Laura Riley , MD, an OB-GYN in New York City. Approximately 3-4% of babies end up “upside-down” in breech presentation, with their feet or buttocks near the cervix.

Breech presentation is typically diagnosed during a visit to an OB-GYN, midwife, or health care provider. Your physician can feel the position of your baby's head through your abdominal wall—or they can conduct a vaginal exam if your cervix is open. A suspected breech presentation should ultimately be confirmed via an ultrasound, after which you and your provider would have a discussion about delivery options, potential issues, and risks.

There are three types of breech babies: frank, footling, and complete. Learn about the differences between these breech presentations.

Frank Breech

With frank breech presentation, your baby’s bottom faces the cervix and their legs are straight up. This is the most common type of breech presentation.

Footling Breech

Like its name suggests, a footling breech is when one (single footling) or both (double footling) of the baby's feet are in the birth canal, where they’re positioned to be delivered first .

Complete Breech

In a complete breech presentation, baby’s bottom faces the cervix. Their legs are bent at the knees, and their feet are near their bottom. A complete breech is the least common type of breech presentation.

Breech Baby

What is a breech position.

A breech baby happens when the baby is positioned in the birth canal with feet down (or bottom-down). This position is perfectly safe for the baby to be in inside the birth canal, until it is time for delivery. Typically, by 36 weeks, most babies move into a head-down position for delivery. However, if the baby remains in a breech position, it can sometimes make for a more difficult or complicated delivery. If the doctor determines the risk is too great to have a vaginal delivery, often times, a C-section will be performed.

There are 3 primary types of breech positions. They include:

Frank breech. This is when the baby’s buttocks is positioned lowest in the birth canal. In this position, the knees are extended toward the abdomen and hips are flexed (legs are straight up in front of the body, with feet near the head). This is the most common breech position.
Complete breech. In this position, the baby’s knees and hips are flexed, and folded under each other.
Footling breech. This happens sometimes when one or both feet of the baby are pointed down toward the birth canal.

There are not usually symptoms associated with a breech baby. However, if you are 36 weeks pregnant and notice the baby’s head is pressing higher up in your abdomen or feel kicking in your lower abdomen, you may want to consult your doctor at your next appointment.

To determine whether your baby is breech, a routine exam later in the pregnancy will help to assess this. During the exam, your doctor will feel the lower and upper abdomen to determine if the baby is breech, and may use an ultrasound or perform a pelvic exam to check the baby's position.

Find a Specialist

Most of the time, doctors don’t know the exact cause of having a breech baby. However, there are reasons that correlate to a higher likelihood of a baby being breech. These reasons include:

Pregnancy with multiples
Premature birth in the past
Second, or more, pregnancy

Treatment

There is no scientific studies to suggest that the following suggestions will help but you can try sitting on a birthing ball or child pose as used in Yoga may help the baby change position. Also walking every day if ok by your doctor as gravity may help.

Breech deliveries require the mother to have a cesarean section in order to deliver the baby safely. Want to know more about Caesarean section deliveries?

Patient Instructions

Breech presentation refers to the baby presenting for delivery with the buttocks or feet first rather than head.

Associated with increased morbidity and mortality for the mother in terms of emergency cesarean section and placenta previa; and for the baby in terms of preterm birth, small fetal size, congenital anomalies, and perinatal mortality.

Incidence decreases as pregnancy progresses and by term occurs in 3% to 4% of singleton term pregnancies.

Treatment options include external cephalic version to increase the likelihood of vaginal birth or a planned cesarean section, the optimal gestation being 37 and 39 weeks, respectively.

Planned cesarean section is considered the safest form of delivery for infants with a persisting breech presentation at term.

Palpation of the area above the symphysis pubis to locate the fetal presenting part

Palpation of the presenting part to confirm presentation, to determine how far the fetus has descended and whether the fetus is engaged.

Ultrasound examination

Premature fetus.

Prematurity is consistently associated with breech presentation. [ 6 ] [ 9 ] This may be due to the smaller size of preterm infants, who are more likely to change their in utero position.

Increasing duration of pregnancy may allow breech-presenting fetuses time to grow, turn spontaneously or by external cephalic version, and remain cephalic-presenting.

Larger fetuses may be forced into a cephalic presentation in late pregnancy due to space or alignment constraints within the uterus.

small for gestational age fetus

Low birth-weight is a risk factor for breech presentation. [ 9 ] [ 11 ] [ 12 ] [ 13 ] [ 14 ] Term breech births are associated with a smaller fetal size for gestational age, highlighting the association with low birth-weight rather than prematurity. [ 6 ]

nulliparity

Women having a first birth have increased rates of breech presentation, probably due to the increased likelihood of smaller fetal size. [ 6 ] [ 9 ]

Relaxation of the uterine wall in multiparous women may reduce the odds of breech birth and contribute to a higher spontaneous or external cephalic version rate. [ 10 ]

fetal congenital anomalies

Congenital anomalies in the fetus may result in a small fetal size or inappropriate fetal growth. [ 9 ] [ 12 ] [ 14 ] [ 15 ]

Anencephaly, hydrocephaly, Down syndrome, and fetal neuromuscular dysfunction are associated with breech presentation, the latter due to its effect on the quality of fetal movements. [ 9 ] [ 14 ]

previous breech delivery

The risk of recurrent breech delivery is 8%, the risk increasing from 4% after one breech delivery to 28% after three. [ 16 ]

The effects of recurrence may be due to recurring specific causal factors, either genetic or environmental in origin.

uterine abnormalities

Women with uterine abnormalities have a high incidence of breech presentation. [ 14 ] [ 17 ] [ 18 ] [ 19 ]

female fetus

Fifty-four percent of breech-presenting fetuses are female. [ 14 ]

abnormal amniotic fluid volume

Both oligohydramnios and polyhydramnios are associated with breech presentation. [ 1 ] [ 12 ] [ 14 ]

Low amniotic fluid volume decreases the likelihood of a fetus turning to a cephalic position; an increased amniotic fluid volume may facilitate frequent change in position.

placental abnormalities

An association between placental implantation in the cornual-fundal region and breech presentation has been reported, although some studies have not found it a risk factor. [ 8 ] [ 20 ] [ 21 ] [ 22 ] [ 10 ] [ 14 ]

The association with placenta previa is also inconsistent. [ 8 ] [ 9 ] [ 22 ] Placenta previa is associated with preterm birth and may be an indirect risk factor.

Pelvic or vaginal examination reveals the buttocks and/or feet, felt as a yielding, irregular mass, as the presenting part. [ 26 ] In cephalic presentation, a hard, round, regular fetal head can be palpated. [ 26 ]

The Leopold maneuver on examination suggests breech position by palpation of the fetal head under the costal margin. [ 26 ]

The baby's heartbeat should be auscultated using a Pinard stethoscope or a hand-held Doppler to indicate the position of the fetus. The fetal heartbeat lies above the maternal umbilicus in breech presentation. [ 1 ]

Tenderness under one or other costal margin as a result of pressure by the harder fetal head.

Pain due to fetal kicks in the maternal pelvis or bladder.

breech position

Visualizes the fetus and reveals its position.

Used to confirm a clinically suspected breech presentation. [ 28 ]

Should be performed by practitioners with appropriate skills in obstetric ultrasound.

Establishes the type of breech presentation by imaging the fetal femurs and their relationship to the distal bones.

Transverse lie

Differentiating Signs/Symptoms

Fetus lies horizontally across the uterus with the shoulder as the presenting part.

Similar predisposing factors such as placenta previa, abnormal amniotic fluid volume, and uterine anomalies, although more common in multiparity. [ 1 ] [ 2 ] [ 29 ]

Differentiating Tests

Clinical examination and fetal auscultation may be indicative.

Ultrasound confirms presentation.

Treatment Approach

Breech presentation <37 weeks' gestation.

The UK Royal College of Obstetricians and Gynaecologists (RCOG) recommends that corticosteroids should be offered to women between 24 and 34+6 weeks' gestation, in whom imminent preterm birth is anticipated. Corticosteroids should only be considered after discussion of risks/benefits at 35 to 36+6 weeks. Given within 7 days of preterm birth, corticosteroids may reduce perinatal and neonatal death and respiratory distress syndrome. [ 32 ] The American College of Obstetricians and Gynecologists (ACOG) recommends a single course of corticosteroids for pregnant women between 24 and 33+6 weeks' gestation who are at risk of preterm delivery within 7 days, including those with ruptured membranes and multiple gestations. It may also be considered for pregnant women starting at 23 weeks' gestation who are at risk of preterm delivery within 7 days. A single course of betamethasone is recommended for pregnant women between 34 and 36+6 weeks' gestation at risk of preterm birth within 7 days, and who have not received a previous course of prenatal corticosteroids. Regularly scheduled repeat courses or serial courses (more than two) are not currently recommended. A single repeat course of prenatal corticosteroids should be considered in women who are less than 34 weeks' gestation, who are at risk of preterm delivery within 7 days, and whose prior course of prenatal corticosteroids was administered more than 14 days previously. Rescue course corticosteroids could be provided as early as 7 days from the prior dose, if indicated by the clinical scenario. [ 33 ]

Magnesium sulfate given before anticipated early preterm birth reduces the risk of cerebral palsy in surviving infants. Physicians electing to use magnesium sulfate for fetal neuroprotection should develop specific guidelines regarding inclusion criteria, treatment regimens, and concurrent tocolysis. [ 34 ]

Breech presentation from 37 weeks' gestation, before labor

ECV is the initial treatment for a breech presentation at term when the patient is not in labor. It involves turning a fetus presenting by the breech to a cephalic (head-down) presentation to increase the likelihood of vaginal birth. [ 35 ] [ 36 ] Where available, it should be offered to all women in late pregnancy, by an experienced clinician, in hospitals with facilities for emergency delivery, and no contraindications to the procedure. [ 35 ] There is no upper time limit on the appropriate gestation for ECV, with success reported at 42 weeks.

There is no general consensus on contraindications to ECV. Contraindications include multiple pregnancy (except after delivery of a first twin), ruptured membranes, current or recent (<1 week) vaginal bleeding, rhesus isoimmunization, other indications for cesarean section (e.g., placenta previa or uterine malformation), or abnormal electronic fetal monitoring. [ 35 ] One systematic review of relative contraindications for ECV highlighted that most contraindications do not have clear empirical evidence. Exceptions include placental abruption, severe preeclampsia/HELLP syndrome, or signs of fetal distress (abnormal cardiotocography and/or Doppler flow). [ 36 ]

The procedure involves applying external pressure and firmly pushing or palpating the mother's abdomen to coerce the fetus to somersault (either forward or backward) into a cephalic position. [ 37 ]

The overall ECV success rate varies but, in a large series, 47% of women following an ECV attempt had a cephalic presentation at birth. [ 35 ] [ 38 ] Various factors influence the success rate. One systematic review found ECV success rates to be 68% overall, with the rate significantly higher for women from African countries (89%) compared with women from non-African countries (62%), and higher among multiparous (78%) than nulliparous women (48%). [ 39 ] Overall, the ECV success rates for nulliparous and multiparous non-African women were 43% and 73%, respectively, while for nulliparous and multiparous African women rates were 79% and 91%, respectively. Another study reported no difference in success rate or rate of cesarean section among women with previous cesarean section undergoing ECV compared with women with previous vaginal birth. However, numbers were small and further studies in this regard are required. [ 40 ]

Women's preference for vaginal delivery is a major contributing factor in their decision for ECV. However, studies suggest women with a breech presentation at term may not receive complete and/or evidence-based information about the benefits and risks of ECV. [ 41 ] [ 42 ] Although up to 60% of women reported ECV to be painful, the majority highlighted the benefits outweigh the risks (71%) and would recommend ECV to their friends or be willing to repeat for themselves (84%). [ 41 ] [ 42 ]

Cardiotocography and ultrasound should be performed before and after the procedure. Tocolysis should be used to facilitate the maneuver, and Rho(D) immune globulin should be administered to women who are Rhesus negative. [ 35 ] Tocolytic agents include adrenergic beta-2 receptor stimulants such as albuterol, terbutaline, or ritodrine (widely used with ECV in some countries, but not yet available in the US). One Cochrane review of tocolytic beta stimulants demonstrates that these are less likely to be associated with failed ECV, and are effective in increasing cephalic presentation and reducing cesarean section. [ 43 ] There is no current evidence to recommend one beta-2 adrenergic receptor agonist over another. Until these data are available, adherence to a local protocol for tocolysis is recommended. The Food and Drug Administration has issued a warning against using injectable terbutaline beyond 48 to 72 hours, or acute or prolonged treatment with oral terbutaline, in pregnant women for the prevention or prolonged treatment of preterm labor, due to potential serious maternal cardiac adverse effects and death. [ 44 ] Whether this warning applies to the subcutaneous administration of terbutaline in ECV is still unclear; however, studies currently support this use. The European Medicines Agency (EMA) recommends that injectable beta agonists should be used for up to 48 hours between the 22nd and 37th week of pregnancy only. They should be used under specialist supervision with continuous monitoring of the mother and unborn baby owing to the risk of adverse cardiovascular effects in both the mother and baby. The EMA no longer recommends oral or rectal formulations for obstetric indications. [ 45 ]

If ECV is successful, pregnancy care should continue as usual for any cephalic presentation. One systematic review assessing the mode of delivery after a successful ECV found that these women were at increased risk for cesarean section and instrumental vaginal delivery compared with women with spontaneous cephalic pregnancies. However, they still had a lower rate of cesarean section following ECV (i.e., 47%) compared with the cesarean section rate for those with a persisting breech (i.e., 85%). With a number needed to treat of three, ECV is still considered to be an effective means of preventing the need for cesarean section. [ 46 ]

Planned cesarean section should be offered as the safest mode of delivery for the baby, even though it carries a small increase in serious immediate maternal complications compared with vaginal birth. [ 24 ] [ 25 ] [ 31 ] In the US, most unsuccessful ECV with persistent breech will be delivered via cesarean section.

A vaginal mode of delivery may be considered by some clinicians as an option, particularly when maternal request is provided, senior and experienced staff are available, there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

Breech presentation from 37 weeks' gestation, during labor

The first option should be a planned cesarean section.

There is a small increase in the risk of serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), including pulmonary embolism, infection, bleeding, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ] Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

Planned cesarean section is safer for babies, but is associated with increased neonatal respiratory distress. The risk is reduced when the section is performed at 39 weeks' gestation. [ 64 ] [ 65 ] [ 66 ] For women undergoing a planned cesarean section, RCOG recommends an informed discussion about the potential risks and benefits of a course of prenatal corticosteroids between 37 and 38+6 weeks' gestation. Although prenatal corticosteroids may reduce admission to the neonatal unit for respiratory morbidity, it is uncertain if there is any reduction in respiratory distress syndrome, transient tachypnea of the newborn, or neonatal unit admission overall. In addition, prenatal corticosteroids may result in harm to the neonate, including hypoglycemia and potential developmental delay. [ 32 ] ACOG does not recommend corticosteroids in women >37 weeks' gestation. [ 33 ]

Undiagnosed breech in labor generally results in cesarean section after the onset of labor, higher rates of emergency cesarean section associated with the least favorable maternal outcomes, a greater likelihood of cord prolapse, and other poor infant outcomes. [ 23 ] [ 67 ] [ 49 ] [ 68 ] [ 69 ] [ 70 ] [ 71 ]

This mode of delivery may be considered by some clinicians as an option for women who are in labor, particularly when delivery is imminent. Vaginal breech delivery may also be considered, where suitable, when delivery is not imminent, maternal request is provided, senior and experienced staff are available, there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

Findings from one systematic review of 27 observational studies revealed that the absolute risks of perinatal mortality, fetal neurologic morbidity, birth trauma, 5-minute Apgar score <7, and neonatal asphyxia in the planned vaginal delivery group were low at 0.3%, 0.7%, 0.7%, 2.4%, and 3.3%, respectively. However, the relative risks of perinatal mortality and morbidity were 2- to 5-fold higher in the planned vaginal than in the planned cesarean delivery group. Authors recommend ongoing judicious decision-making for vaginal breech delivery for selected singleton, term breech babies. [ 72 ]

ECV may also be considered an option for women with breech presentation in early labor, when delivery is not imminent, provided that the membranes are intact.

A woman presenting with a breech presentation <37 weeks is an area of clinical controversy. Optimal mode of delivery for preterm breech has not been fully evaluated in clinical trials, and the relative risks for the preterm infant and mother remain unclear. In the absence of good evidence, if diagnosis of breech presentation prior to 37 weeks' gestation is made, prematurity and clinical circumstances should determine management and mode of delivery.

Primary Options

12 mg intramuscularly every 24 hours for 2 doses

6 mg intramuscularly every 12 hours for 4 doses

The UK Royal College of Obstetricians and Gynaecologists recommends that corticosteroids should be offered to women between 24 and 34+6 weeks' gestation, in whom imminent preterm birth is anticipated. Corticosteroids should only be considered after discussion of risks/benefits at 35 to 36+6 weeks. Given within 7 days of preterm birth, corticosteroids may reduce perinatal and neonatal death and respiratory distress syndrome. [ 32 ]

The American College of Obstetricians and Gynecologists recommends a single course of corticosteroids for pregnant women between 24 and 33+6 weeks' gestation who are at risk of preterm delivery within 7 days, including those with ruptured membranes and multiple gestations. It may also be considered for pregnant women starting at 23 weeks' gestation who are at risk of preterm delivery within 7 days. A single course of betamethasone is recommended for pregnant women between 34 and 36+6 weeks' gestation at risk of preterm birth within 7 days, and who have not received a previous course of prenatal corticosteroids. Regularly scheduled repeat courses or serial courses (more than two) are not currently recommended. A single repeat course of prenatal corticosteroids should be considered in women who are less than 34 weeks' gestation, who are at risk of preterm delivery within 7 days, and whose prior course of prenatal corticosteroids was administered more than 14 days previously. Rescue course corticosteroids could be provided as early as 7 days from the prior dose, if indicated by the clinical scenario. [ 33 ]

consult specialist for guidance on dose

external cephalic version (ECV)

There is no upper time limit on the appropriate gestation for ECV; it should be offered to all women in late pregnancy by an experienced clinician in hospitals with facilities for emergency delivery and no contraindications to the procedure. [ 35 ] [ 36 ]

ECV involves applying external pressure and firmly pushing or palpating the mother's abdomen to coerce the fetus to somersault (either forward or backward) into a cephalic position. [ 37 ]

Cardiotocography and ultrasound should be performed before and after the procedure.

If ECV is successful, pregnancy care should continue as usual for any cephalic presentation. A systematic review assessing the mode of delivery after a successful ECV found that these women were at increased risk for cesarean section and instrumental vaginal delivery compared with women with spontaneous cephalic pregnancies. However, they still had a lower rate of cesarean section following ECV (i.e., 47%) compared with the cesarean section rate for those with a persisting breech (i.e., 85%). With a number needed to treat of 3, ECV is still considered to be an effective means of preventing the need for cesarean section. [ 46 ]

tocolytic agents

see local specialist protocol for dosing guidelines

Tocolytic agents include adrenergic beta-2 receptor stimulants such as albuterol, terbutaline, or ritodrine (widely used with external cephalic version [ECV] in some countries, but not yet available in the US). They are used to delay or inhibit labor and increase the success rate of ECV. There is no current evidence to recommend one beta-2 adrenergic receptor agonist over another. Until these data are available, adherence to a local protocol for tocolysis is recommended.

The Food and Drug Administration has issued a warning against using injectable terbutaline beyond 48-72 hours, or acute or prolonged treatment with oral terbutaline, in pregnant women for the prevention or prolonged treatment of preterm labor, due to potential serious maternal cardiac adverse effects and death. [ 44 ] Whether this warning applies to the subcutaneous administration of terbutaline in ECV is still unclear; however, studies currently support this use. The European Medicines Agency (EMA) recommends that injectable beta agonists should be used for up to 48 hours between the 22nd and 37th week of pregnancy only. They should be used under specialist supervision with continuous monitoring of the mother and unborn baby owing to the risk of adverse cardiovascular effects in both the mother and baby. The EMA no longer recommends oral or rectal formulations for obstetric indications. [ 45 ]

A systematic review found there was no evidence to support the use of nifedipine for tocolysis. [ 73 ]

There is insufficient evidence to evaluate other interventions to help ECV, such as fetal acoustic stimulation in midline fetal spine positions, or epidural or spinal analgesia. [ 43 ]

Rho(D) immune globulin

300 micrograms intramuscularly as a single dose

Nonsensitized Rh-negative women should receive Rho(D) immune globulin. [ 35 ]

The indication for its administration is to prevent rhesus isoimmunization, which may affect subsequent pregnancy outcomes.

Rho(D) immune globulin needs to be given at the time of external cephalic version and should be given again postpartum to those women who give birth to an Rh-positive baby. [ 74 ]

It is best administered as soon as possible after the procedure, usually within 72 hours.

Dose depends on brand used. Dose given below pertains to most commonly used brands. Consult specialist for further guidance on dose.

elective cesarean section/vaginal breech delivery

Mode of delivery (cesarean section or vaginal breech delivery) should be based on the experience of the attending clinician, hospital policies, maternal request, and the presence or absence of complicating factors. In the US, most unsuccessful external cephalic version (ECV) with persistent breech will be delivered via cesarean section.

Cesarean section, at 39 weeks or greater, has been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ] Although safer for these babies, there is a small increase in serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), as well as long-term risks for future pregnancies, including pulmonary embolism, bleeding, infection, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ] Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

Vaginal delivery may be considered by some clinicians as an option, particularly when maternal request is provided, when senior and experienced staff are available, when there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

For women undergoing a planned cesarean section, the UK Royal College of Obstetricians and Gynaecologists recommends an informed discussion about the potential risks and benefits of a course of prenatal corticosteroids between 37 and 38+6 weeks' gestation. Although prenatal corticosteroids may reduce admission to the neonatal unit for respiratory morbidity, it is uncertain if there is any reduction in respiratory distress syndrome, transient tachypnea of the newborn, or neonatal unit admission overall. In addition, prenatal corticosteroids may result in harm to the neonate, including hypoglycemia and potential developmental delay. [ 32 ] The American College of Obstetricians and Gynecologists does not recommend corticosteroids in women >37 weeks' gestation. [ 33 ]

It is best administered as soon as possible after delivery, usually within 72 hours.

Administration of postpartum Rho (D) immune globulin should not be affected by previous routine prenatal prophylaxis or previous administration for a potentially sensitizing event. [ 74 ]

≥37 weeks' gestation in labor: no imminent delivery

planned cesarean section

For women with breech presentation in labor, planned cesarean section at 39 weeks or greater has been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ]

Although safer for these babies, there is a small increase in serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), as well as long-term risks for future pregnancies, including pulmonary embolism, infection, bleeding, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ] Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

Continuous cardiotocography monitoring should continue until delivery. [ 24 ] [ 25 ]

vaginal breech delivery

This mode of delivery may be considered by some clinicians as an option, particularly when maternal request is provided, when senior and experienced staff are available, when there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

For women with persisting breech presentation, planned cesarean section has, however, been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ]

ECV may also be considered an option for women with breech presentation in early labor, provided that the membranes are intact.

There is no upper time limit on the appropriate gestation for ECV. [ 35 ]

Involves applying external pressure and firmly pushing or palpating the mother's abdomen to coerce the fetus to somersault (either forward or backward) into a cephalic position. [ 37 ]

Relative contraindications include placental abruption, severe preeclampsia/HELLP syndrome, and signs of fetal distress (abnormal cardiotocography and/or abnormal Doppler flow). [ 35 ] [ 36 ]

Rho(D) immune globulin needs to be given at the time of ECV and should be given again postpartum to those women who give birth to an Rh-positive baby. [ 74 ]

≥37 weeks' gestation in labor: imminent delivery

cesarean section

For women with persistent breech presentation, planned cesarean section has been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ] Although safer for these babies, there is a small increase in serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), as well as long-term risks for future pregnancies, including pulmonary embolism, infection, bleeding, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ] Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

This mode of delivery may be considered by some clinicians as an option, particularly when delivery is imminent, maternal request is provided, when senior and experienced staff are available, when there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

It is best administered as soon as possible after the delivery, usually within 72 hours.

External cephalic version before term

Moxibustion, postural management, follow-up overview, perinatal complications.

Compared with cephalic presentation, persistent breech presentation has increased frequency of cord prolapse, abruptio placentae, prelabor rupture of membranes, perinatal mortality, fetal distress (heart rate <100 bpm), preterm delivery, lower fetal weight. [ 10 ] [ 11 ] [ 67 ]

complications of cesarean section

The long-term risks include potential compromise of future obstetric performance, increased risk of repeat cesarean section, infertility, uterine rupture, placenta accreta, placental abruption, and emergency hysterectomy. [ 60 ] [ 61 ] [ 62 ] [ 63 ] The evidence suggests that using sutures, rather than staples, for wound closure after cesarean section reduces the incidence of wound dehiscence. [ 59 ]

Emergency cesarean section, compared with planned cesarean section, has demonstrated a higher risk of severe obstetric morbidity, intra-operative complications, postoperative complications, infection, blood loss >1500 mL, fever, pain, tiredness, and breast-feeding problems. [ 23 ] [ 48 ] [ 50 ] [ 70 ] [ 81 ]

Breech presentation

Overview  
Theory  
Diagnosis  
Management  
Follow up  
Resources  

Breech presentation refers to the baby presenting for delivery with the buttocks or feet first rather than head.

Incidence decreases as pregnancy progresses and by term occurs in 3% to 4% of singleton term pregnancies.

Treatment options include external cephalic version to increase the likelihood of vaginal birth or a planned cesarean section, the optimal gestation being 37 and 39 weeks, respectively.

Planned cesarean section is considered the safest form of delivery for infants with a persisting breech presentation at term.

Breech presentation in pregnancy occurs when a baby presents with the buttocks or feet rather than the head first (cephalic presentation) and is associated with increased morbidity and mortality for both the mother and the baby.

Current obstetric and gynecologic diagnosis and treatment. New York: McGraw-Hill Professional; 2002. There is good current evidence regarding effective management of breech presentation in late pregnancy using external cephalic version and/or planned cesarean section.

10 Signs of a Breech Baby: How to Tell if Your Baby is Breech

A mother’s instincts are strong. For the last 9 months, you’ve become well-acquainted with your baby. You’ve felt his movements, you know his habits.

Now, things feel off. Your gut is telling you that your baby isn’t where he should be.

How to Tell if Your Baby is Breech - 10 Signs of a Breech Baby

If you’re wondering how to tell if your baby is breech, you’re not alone. During my first pregnancy, I searched for the signs of a breech baby all over the internet and could only find forum posts by other women that were just as confused.

If you’re having the same trouble, this post is for you.

This article describes the most commonly reported signs of a breech baby and how to tell if your baby is breech. Hopefully, by the end, you will either find peace of mind or confirmation that a doctor’s visit is in order.

How to Tell if Your Baby is Breech: 10 Signs of a Breech Baby

This post may contai n affiliate links . If you make a purchase from one of the links I will make a small commission at no charge to you. I only recommend what I trust. Blunders in Babyland does not diagnose, treat, or give out any professional advice for any medical conditions.

First things, first. Let’s talk about the differences between a cephalic baby and a breech baby . When your baby is cephalic, he’s head down. The optimal position for giving birth is anterior cephalic. Basically, in this position, your baby’s head will fit nicely into the birth canal.

If your baby’s head is near your ribs and his feet are in your pelvis, he’s breech . There are several different types of breech positions, but we’ll get to that in another post .

Breech births are possible , but they are generally more difficult and, at times, can be dangerous. Generally speaking, most providers do not want to mess with a vaginal breech birth.

Now, you should know that the only way to know that your baby is breech is to confirm with your provider .

The information below is based on the experiences of other mothers, midwives, and myself. It’s important to be aware of these signs, especially later in your pregnancy, because it will give you the chance to take the necessary steps to correct it.

Signs Your Baby is NOT Breech

If you don’t know already, here are some pretty strong indicators that your baby is head down:

Kicks near the rib cage
Fluttering in the pelvis (baby’s fingers)
Punches to pelvis
Pressure or heaviness in the pelvis ( sign of engagement )
Small, pliable bulge near the rib cage (the baby’s butt)
Hiccups below the belly button

If you’re seeing these signs then congratulations ! There’s a good chance your baby is head down.

How to Tell if Your Baby is Breech With Belly Mapping

Before we dive into the signs of a breech baby, let’s talk about one more important concept: belly mapping. My first pregnancy, I had no idea what belly mapping is. Now, I love using this technique to give me some peace of mind that my baby is head down.

In case you’re new to the concept, belly mapping uses a combination of light palpitation, drawing, and tracking your baby’s movements to gauge his position. If your baby is vertex, belly mapping is a great tool to make sure your baby is in the optimal birthing position.

Belly mapping a breech baby can be tricky since your baby’s butt feels a lot like his head. The success of belly mapping largely depends on you and your baby’s physiology. For example, if you’re overweight or have an anterior placenta, belly mapping will be less reliable.

Belly mapping is also a great way to check your baby’s progress if your provider diagnoses him as breech . Just take into account the special movements and characteristics of a breech baby.

10 Most Common Signs of a Breech Baby

Hard bulge near rib cage.

This is the most common sign of a breech baby, but it’s also the most difficult to verify. Many moms mistake their baby’s butt for a head. It can be really difficult to feel the difference from the outside. Generally speaking, if you press on the bulge and it moves or you get a nice kick, that’s a good indication that it’s your baby’s butt.

Personally, I noticed that the head was much more prominent and less mobile. Meanwhile, her butt could be pushed around and would disappear for a few hours.

Baby Will Not Engage

Lightening, engaging, or dropping.

This magical transition happens sometime during your last few weeks of pregnancy. Your baby’s head migrates into your pelvis, giving your poor lungs a small break. You can tell that your baby has engaged when you feel pressure on your pelvis or you need to pee more frequently.

Many breech babies do not engage until labor or until he has flipped head down.

Just keep in mind that your baby may not be engaging for several reasons; some babies simply don’t engage until labor (especially with new moms) and others won’t engage because they are posterior.

Light Kicks or Punches to the Upper Abdomen

This was a huge sign for me. After a terrible night of twisting and turning, I felt a hard bulge by my rib cage and only small kicks into my side. Considering my baby had been an amateur soccer player until this point, this was definitely a red flag.

A few days later, an ultrasound established that I had a Frank Breech.

If you have a particularly feisty baby, it can be difficult to tell the difference between kicks and punches. A kick should feel more pronounced, with a larger footprint. A punch is often lighter.

Keep in mind that an anterior head down baby (the optimal birthing position) will not kick your front upper abdomen either. You’ll feel those kicks behind your ribs.

SHORT ON TIME? PIN IT FOR LATER!

Signs of a Breech Baby You Need to Know About

Kicks to Pelvis or Cervix (Footling Breech)

You’ll know when your baby kicks your cervix. It’ll feel like a kick to the crotch…from the inside. This is not to be confused with a punch to the cervix. When a baby’s hands are near your pelvis, you might feel a slight tickling or butterfly from her fingers. That’s a great indication that your baby is NOT breech.

Unusual or Fetal Painful Movement

The further you are in your gestation, the more snug your baby’s quarters. You will be much more likely to feel your baby flip. For some women, this is just mildly uncomfortable; for others, it’s very, very painful.

In my case, flipping was very painful. The night she turned breech it felt like my insides were being churned. I felt a similar experience during the night (I suspect) she turned head down. However, many women do not experience pain when their baby turns. This symptom largely depends on your amniotic fluid, your baby’s size, and your physiology.

If you do feel prolonged pain, go to your doctor, if only for your peace of mind.

Pressure on Your Rib Cage

Your baby’s head is the largest part of her body. When she’s engaged, all of that pressure rests not-so-comfortably on your pelvic bone. One sign of a breech baby is pressure on your lungs and rib cage. This can make it difficult to breathe, sleep, or even sit.

High Heartbeat Location

Some moms report finding their breech baby’s heartbeat above their belly button. If you get these results, try not to panic. Your amniotic liquid may transfer the sound, giving an inaccurate representation.

Head Can’t be Found in Pelvis During a Palpitation

This is how most women discover that their baby is breech. At your weekly checkup, your doctor may palpitate to feel your baby’s head. If your baby is breech, your pelvis will feel unusually squishy (as opposed to a hard lump where the head is).

However, many doctors will not rely on palpitation alone to determine if a baby is breech. Most likely, he will schedule an ultrasound visit to confirm your baby’s position.

Hiccups Above the Belly Button

One of the most commonly reported (though thankfully inaccurate) signs of a breech baby is tiny hiccups above the belly button.

This was actually one of the clues I noticed when my baby was breech. After my baby turned head down, I felt hiccups in my pelvis again. If your only symptom of a breech baby is high hiccups, try not to worry. Like your baby’s heartbeat, you may be feeling the vibrations travel or his little feet twitching.

Discomfort and Soreness

When your baby is breech, your upper torso may feel very, very uncomfortable and, in some cases, tender.

Your baby is designed to nestle into your pelvis, preparing the birth canal and allowing his little body to grow. When your baby is breech, the biggest part of him is sitting on your lungs and ribs. You’re not feeling the same relief that you might for a head down baby. In fact, you might feel very stretched and the constant pressure can feel like a deep bruise.

How to Tell if Your Baby is Actually Breech - Signs of a Breech Baby

What do I do if I Think My Baby is Breech?

Only 3-4% of babies reach full-term breech. Even if you’re feeling a couple of these symptoms, chances are, your baby is still head-down. However, you should always trust your gut (literally, in this case). If you’re beginning to notice changes in your baby’s position, visit your doctor. At the very least, you’ll find some reassurance.

If you do discover that your baby is breech, don’t panic . It’s never too late to flip a baby, even this late in the third trimester. My baby turned at 39 weeks! It is possible, I promise.

Related Post: Turning a Breech Baby: 10 Ways to Turn Your Breech Baby Naturally

If you find that your baby is head-down, it may be a good idea to belly map to check which direction your baby is facing. Some of the signs of a breech baby are also indicative of a posterior baby. Depending on you and your baby, a posterior presentation can mean a harder, longer labor.

The good news is, even if your baby is posterior , there are plenty of methods to encourage him into the optimal birthing position.

That’s it, Mama!

Most of all, I hope these signs either reassure you or convince you to visit your doctor. Remember, if you do find out that your baby is breech, it’s not the end of the world–even after 36 weeks.

Hi my name is Caren, I’m 33 weeks pregnant with twins and they are both breech Im so concerned, the kicks at my lower belly are very painful sometimes Im out out of breath please advice what can I do to turn the babies please.

Hey Caren, I’m so sorry you’re having painful kicks. Definitely speak to your provider about these concerns. They will be able to check the your twins’ positioning and give you the medical advice and peace of mind you need. But, from one mom to another, let me encourage you: I felt a ton of kicks/punches that “took my breath away” during my pregnancies…while my girls were head down and breech! Both girls turned head down by 39 weeks and the birth went great. There’s an article linked above that details which positions/techniques I used. Once again, not medical advice, just tips that I used in my personal situation 🙂 Much love to you and your beautiful babies!

I am 35weeks and my baby is breech, the doctor ask me to prepare for CS and am sad… I hope the baby still turn

I’m so sorry to hear that. I hope your baby did end up turning. If not, your birth story is unique and beautiful whether it ends in a c-section or natural birth <3

Just coming back from the clinic and they say my baby is breech at 36 weeks

I’m 36 weeks and I had expressed concern to my OBGYN at a much earlier date about the possiblity of having a breech baby. She told me then that there was still plenty of time for him to flip, and to try not to worry too much about it until closer to delivery. Well, I’m almost 37 weeks now and she still hasn’t checked his position. Most days I notice a firm bulge on my right side by my ribs and experience movements all across the center of my abdomen. Occasionally there will be pressure in my pelvic region, but by the end of the night it’s all back to the center. I dont know what to do since this is my 1st child, and as time dwindles I get more and more uneasy.

Hey Brooke, I can definitely understand your concern here! Honestly, from your description it sounds like it could go either way. It’s SO hard to FEEL the difference between a breech baby and head down baby, the only real way to know for sure is by your provider. I definitely would NOT worry (not many babies are breech) but I would also mention your concerns to your OBGYN again. Maybe she can feel around, perform an unofficial ultrasound (if she has a portable ultrasound handy) or she can check the heartbeat location. At the very least, it will give you peace of mind!

I am 32weeks, and my baby is in breech, pls I pray he or she will turn.and my left abdomen is paining me, mostly when ever am walking, pls I want to know the reason for that.

Annita, I’m sorry to hear that. Try not to worry though, 32 weeks is still plenty of time for her to turn! Don’t lose hope! I would definitely speak to your provider about the abdomen pain. I experienced this as well and it was simply because my daughter’s position was the worst (at one point, she was transverse…ouch!). Your pain could be completely normal, but I would double-check just in case 🙂

I found out at 37 weeks my baby was breech. The medical professional did not recognize this, I ask for the ultrasound which made the late determination. The breech doctor saw me at 38 weeks and told me my baby was too big and could not flip. I diligently did not listen and did all breech remedies to flip her. I slept on inverted board upside down, did pelvic floor excersizes, ate foods to induce labor. I even did not show up for my scheduled C section because I believed I could get her into position. So 5 days after missed C section I went into natural labor, I checked into the hospital. I spent 8 hours in labor, all the while the head midwife pleaded with me to get C section. So I caved and was tired. The doctor said my baby was at risk and we were both declining. I am still sad about this birth birth and delivery. Though my daughter is now two years of age and is healthy. I guess live and learn is all I can take from this experience. Good luck to any woman with breech births.

Aw, Shay thank you for sharing your story. I’ve heard a few stories where the babies were able to flip head down just in the nick of time and others, like yours, where that baby just would not flip! I know it can be such a bummer, but who knows what might be going on behind the scenes! Maybe the baby instinctively knew that flipping could be more dangerous than her current position. In any case, I am so, so glad that your little one is healthy and completely oblivious to her little prenatal adventure!

Breech, posterior, transverse lie: What position is my baby in?

Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. At the time of delivery, 97 percent of babies are head-down (cephalic presentation). But there are several other possibilities, including feet or bottom first (breech) as well as sideways (transverse lie) and diagonal (oblique lie).

Fetal presentation and position

During the last trimester of your pregnancy, your provider will check your baby's presentation by feeling your belly to locate the head, bottom, and back. If it's unclear, your provider may do an ultrasound or an internal exam to feel what part of the baby is in your pelvis.

Fetal position refers to whether the baby is facing your spine (anterior position) or facing your belly (posterior position). Fetal position can change often: Your baby may be face up at the beginning of labor and face down at delivery.

Here are the many possibilities for fetal presentation and position in the womb.

Medical illustrations by Jonathan Dimes

Head down, facing down (anterior position)

A baby who is head down and facing your spine is in the anterior position. This is the most common fetal presentation and the easiest position for a vaginal delivery.

This position is also known as "occiput anterior" because the back of your baby's skull (occipital bone) is in the front (anterior) of your pelvis.

Head down, facing up (posterior position)

In the posterior position , your baby is head down and facing your belly. You may also hear it called "sunny-side up" because babies who stay in this position are born facing up. But many babies who are facing up during labor rotate to the easier face down (anterior) position before birth.

Posterior position is formally known as "occiput posterior" because the back of your baby's skull (occipital bone) is in the back (posterior) of your pelvis.

In the frank breech presentation, both the baby's legs are extended so that the feet are up near the face. This is the most common type of breech presentation. Breech babies are difficult to deliver vaginally, so most arrive by c-section .

Some providers will attempt to turn your baby manually to the head down position by applying pressure to your belly. This is called an external cephalic version , and it has a 58 percent success rate for turning breech babies. For more information, see our article on breech birth .

Complete breech

A complete breech is when your baby is bottom down with hips and knees bent in a tuck or cross-legged position. If your baby is in a complete breech, you may feel kicking in your lower abdomen.

Incomplete breech

In an incomplete breech, one of the baby's knees is bent so that the foot is tucked next to the bottom with the other leg extended, positioning that foot closer to the face.

Single footling breech

In the single footling breech presentation, one of the baby's feet is pointed toward your cervix.

Double footling breech

In the double footling breech presentation, both of the baby's feet are pointed toward your cervix.

Transverse lie

In a transverse lie, the baby is lying horizontally in your uterus and may be facing up toward your head or down toward your feet. Babies settle this way less than 1 percent of the time, but it happens more commonly if you're carrying multiples or deliver before your due date.

If your baby stays in a transverse lie until the end of your pregnancy, it can be dangerous for delivery. Your provider will likely schedule a c-section or attempt an external cephalic version , which is highly successful for turning babies in this position.

Oblique lie

In rare cases, your baby may lie diagonally in your uterus, with his rump facing the side of your body at an angle.

Like the transverse lie, this position is more common earlier in pregnancy, and it's likely your provider will intervene if your baby is still in the oblique lie at the end of your third trimester.

Review question

What is the most effective way of managing a longitudinal lie fetal malpresentation (breech presentation) in late pregnancy?

Introduction

Breech presentation of the fetus in late pregnancy may result in prolonged or obstructed labour with resulting risks to both woman and fetus. Interventions to correct breech presentation (to cephalic) before labour and birth are important for the woman’s and the baby’s health. The aim of this review is to determine the most effective way of managing a breech presentation in late pregnancy.

Summary of the protocol

Please see Table 1 for a summary of the Population, Intervention, Comparison and Outcome (PICO) characteristics of this review.

Economic evidence statements

The committee’s discussion of the evidence

Interpreting the evidence, the outcomes that matter most.

Provision of antenatal care is important for the health and wellbeing of both mother and baby with the aim of avoiding adverse pregnancy outcomes and enhancing maternal satisfaction and wellbeing. Breech presentation in labour may be associated with adverse outcomes for the fetus, which has contributed to an increased likelihood of caesarean birth. The committee therefore agreed that cephalic presentation in labour and method of birth were critical outcomes for the woman, and admission to SCBU/NICU, fetal death after 36 +0 weeks gestation, and infant death up to 4 weeks chronological age were critical outcomes for the baby. Apgar score <7 at 5 minutes and birth before 39 +0 weeks of gestation were important outcomes for the baby.

The quality of the evidence

The quality of the evidence for interventions for managing a longitudinal lie fetal malpresentation (that is breech presentation) in late pregnancy ranged from very low to high, with most of the evidence being of a very low or low quality.

This was predominately due to serious overall risk of bias in some outcomes; imprecision around the effect estimate in some outcomes; indirect population in some outcomes; and the presence of serious heterogeneity in some outcomes, which was unresolved by subgroup analysis. The majority of included studies had a small sample size, which contributed to imprecision around the effect estimate.

No evidence was identified to inform the outcomes of infant death up to 4 weeks chronological age and birth before 39 +0 weeks of gestation.

There was no publication bias identified in the evidence. However, the committee noted the influence pharmacological developers may have in these trials as funders, and took this into account in their decision making.

Benefits and harms

The committee discussed that in the case of breech presentation, a discussion with the woman about the different options and their potential benefits, harms and implications is needed to ensure an informed decision. The committee discussed that some women may prefer a breech vaginal birth or choose an elective caesarean birth, and that her preferences should be supported, in line with shared decision making.

The committee discussed that external cephalic version is standard practice for managing breech presentation in uncomplicated singleton pregnancies at or after 36+0 weeks. The committee discussed that there could be variation in the success rates of ECV based on the experience of the healthcare professional providing the ECV. There was some evidence supporting the use of ECV for managing a breech presentation in late pregnancy. The evidence showed ECV had a clinically important benefit in terms of cephalic presentations in labour and cephalic vaginal deliveries, when compared to no intervention. The committee noted that the evidence suggested that ECV was not harmful to the baby, although the effect estimate was imprecise relating to the relative rarity of the fetal death as an outcome.

Cephalic (head-down) vaginal birth is preferred by many women and the evidence suggests that external cephalic version is an effective way to achieve this. The evidence suggested ECV increased the chance for a cephalic vaginal birth and the committee agreed that it was important to explain this to the woman during her consultation.

The committee discussed the optimum timing for ECV. Timing of ECV must take into account the likelihood of the baby turning naturally before a woman commences labour and the possibility of the baby turning back to a breech presentation after ECV if it is done too early. The committee noted that in their experience, current practice was to perform ECV at 37 gestational weeks. The majority of the evidence demonstrating a benefit of ECV in this review involved ECV performed around 37 gestational weeks, although the review did not look for studies directly comparing different timings of ECV and their relative success rates.

The evidence in this review excluded women with previous complicated pregnancies, such as those with previous caesarean section or uterine surgery. The committee discussed that a previous caesarean section indicates a complicated pregnancy and that this population of women are not the focus of this guideline, which concentrates on women with uncomplicated pregnancies.

The committee’s recommendations align with other NICE guidance and cross references to the NICE guideline on caesarean birth and the section on breech presenting in labour in the NICE guideline on intrapartum care for women with existing medical conditions or obstetric complications and their babies were made.

ECV combined with pharmacological agents

There were some small studies comparing a variety of pharmacological agents (including β2 agonists, Ca 2+ channel blockers, µ-receptor agonists and nitric oxide donors) given alongside ECV. Overall the evidence typically showed no clinically important benefit of adding any pharmacological agent to ECV except in comparisons with a control arm with no ECV where it was not possible to isolate the effect of the ECV versus the pharmacological agent. The evidence tended toward benefit most for β2 agonists and µ-receptor agonists however there was no consistent or high quality evidence of benefit even for these agents. The committee agreed that although these pharmacological agents are used in practice, there was insufficient evidence to make a recommendation supporting or refuting their use or on which pharmacological agent should be used.

The committee discussed that the evidence suggesting µ-receptor agonist, remifentanil, had a clinically important benefit in terms reducing breech vaginal births after unsuccessful ECV was biologically implausible. The committee noted that this pharmacological agent has strong sedative effects, depending on the dosage, and therefore studies comparing it to a placebo had possible design flaws as it would be obvious to all parties whether placebo or active drug had been received. The committee discussed that the risks associated with using remifentanil such as respiratory depression, likely outweigh any potential added benefit it may have on managing breech presentation.

There was some evidence comparing different anaesthetics together with ECV. Although there was little consistent evidence of benefit overall, one small study of low quality showed a combination of 2% lidocaine and epinephrine via epidural catheter (anaesthesia) with ECV showed a clinically important benefit in terms of cephalic presentations in labour and the method of birth. The committee discussed the evidence and agreed the use of anaesthesia via epidural catheter during ECV was uncommon practice in the UK and could be expensive, overall they agreed the strength of the evidence available was insufficient to support a change in practice.

Postural management

There was limited evidence on postural management as an intervention for managing breech presentation in late pregnancy, which showed no difference in effectiveness. Postural management was defined as ‘knee-chest position for 15 minutes, 3 times a day’. The committee agreed that in their experience women valued trying interventions at home first which might make postural management an attractive option for some women, however, there was no evidence that postural management was beneficial. The committee also noted that in their experience postural management can cause notable discomfort so it is not an intervention without disadvantages.

Cost effectiveness and resource use

A systematic review of the economic literature was conducted but no relevant studies were identified which were applicable to this review question.

The committee’s recommendations to offer external cephalic version reinforces current practice. The committee noted that, compared to no intervention, external cephalic version results in clinically important benefits and that there would also be overall downstream cost savings from lower adverse events. It was therefore the committee’s view that offering external cephalic version is cost effective and would not entail any resource impact.

Breech Baby: Causes, Complications, Turning & Delivery
A breech baby, or breech birth, is when your baby's feet or buttocks are positioned to come out of your vagina first. Your baby's head is up closest to your chest and its bottom is closest to your vagina. Most babies will naturally move so their head is positioned to come out of the vagina first during birth. Breech is common in early ...
Breech presentation
Summary. Breech presentation refers to the baby presenting for delivery with the buttocks or feet first rather than head. Associated with increased morbidity and mortality for the mother in terms of emergency cesarean section and placenta previa; and for the baby in terms of preterm birth, small fetal size, congenital anomalies, and perinatal ...
Breech Presentation
Breech Births. In the last weeks of pregnancy, a baby usually moves so his or her head is positioned to come out of the vagina first during birth. This is called a vertex presentation. A breech presentation occurs when the baby's buttocks, feet, or both are positioned to come out first during birth. This happens in 3-4% of full-term births.
Breech: Types, Risk Factors, Treatment, Complications
At full term, around 3%-4% of births are breech. The different types of breech presentations include: Complete: The fetus's knees are bent, and the buttocks are presenting first. Frank: The fetus's legs are stretched upward toward the head, and the buttocks are presenting first. Footling: The fetus's foot is showing first.
Breech Presentation
Breech presentation refers to the fetus in the longitudinal lie with the buttocks or lower extremity entering the pelvis first. The three types of breech presentation include frank breech, complete breech, and incomplete breech. In a frank breech, the fetus has flexion of both hips, and the legs are straight with the feet near the fetal face, in a pike position. The complete breech has the ...
Fetal Presentation, Position, and Lie (Including Breech Presentation
Presentation refers to the part of the fetus's body that leads the way out through the birth canal (called the presenting part). Usually, the head leads the way, but sometimes the buttocks (breech presentation), shoulder, or face leads the way.
Fetal Presentation, Position, and Lie (Including Breech Presentation
Breech presentation makes delivery difficult ,primarily because the presenting part is a poor dilating wedge. Having a poor dilating wedge can lead to incomplete cervical dilation, because the presenting part is narrower than the head that follows. The head, which is the part with the largest diameter, can then be trapped during delivery.
If Your Baby Is Breech
In a breech presentation, the body comes out first, leaving the baby's head to be delivered last. The baby's body may not stretch the cervix enough to allow room for the baby's head to come out easily. There is a risk that the baby's head or shoulders may become wedged against the bones of the mother's pelvis.
Overview of breech presentation
The main types of breech presentation are: Frank breech - Both hips are flexed and both knees are extended so that the feet are adjacent to the head ( figure 1 ); accounts for 50 to 70 percent of breech fetuses at term. Complete breech - Both hips and both knees are flexed ( figure 2 ); accounts for 5 to 10 percent of breech fetuses at term.
Breech Presentation: Types, Causes, Risks
