• Continuing Education Activity

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. This activity reviews the cause and pathophysiology of breech presentation and highlights the role of the interprofessional team in its management.

• Describe the pathophysiology of breech presentation.
• Review the physical exam of a patient with a breech presentation.
• Summarize the treatment options for breech presentation.
• Explain the importance of improving care coordination among interprofessional team members to improve outcomes for patients affected by breech presentation.
• Introduction

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 fetus sitting with flexion of both hips and both legs in a tuck position. Finally, the incomplete breech can have any combination of one or both hips extended, also known as footling (one leg extended) breech, or double footling breech (both legs extended). [1] [2] [3]

Clinical conditions associated with breech presentation include those that may increase or decrease fetal motility, or affect the vertical polarity of the uterine cavity. Prematurity, multiple gestations, aneuploidies, congenital anomalies, Mullerian anomalies, uterine leiomyoma, and placental polarity as in placenta previa are most commonly associated with a breech presentation.  Also, a previous history of breech presentation at term increases the risk of repeat breech presentation at term in subsequent pregnancies. [4] [5] These are discussed in more detail in the pathophysiology section.

• Epidemiology

Breech presentation occurs in 3% to 4% of all term pregnancies. A higher percentage of breech presentations occurs with less advanced gestational age. At 32 weeks, 7% of fetuses are breech, and 28 weeks or less, 25% are breech.

Specifically, following one breech delivery, the recurrence rate for the second pregnancy was nearly 10%, and for a subsequent third pregnancy, it was 27%. Prior cesarean delivery has also been described by some to increase the incidence of breech presentation two-fold.

• Pathophysiology

As mentioned previously, the most common clinical conditions or disease processes that result in the breech presentation are those that affect fetal motility or the vertical polarity of the uterine cavity. [6] [7]

Conditions that change the vertical polarity or the uterine cavity, or affect the ease or ability of the fetus to turn into the vertex presentation in the third trimester include:

• Mullerian anomalies: Septate uterus, bicornuate uterus, and didelphys uterus 
• Placentation: Placenta previa as the placenta is occupying the inferior portion of the uterine cavity. Therefore, the presenting part cannot engage
• Uterine leiomyoma: Mainly larger myomas located in the lower uterine segment, often intramural or submucosal, that prevent engagement of the presenting part.
• Prematurity
• Aneuploidies and fetal neuromuscular disorders commonly cause hypotonia of the fetus, inability to move effectively
• Congenital anomalies:  Fetal sacrococcygeal teratoma, fetal thyroid goiter
• Polyhydramnios: Fetus is often in unstable lie, unable to engage
• Oligohydramnios: Fetus is unable to turn to vertex due to lack of fluid
• Laxity of the maternal abdominal wall: Uterus falls forward, the fetus is unable to engage in the pelvis.

The risk of cord prolapse varies depending on the type of breech. Incomplete or footling breech carries the highest risk of cord prolapse at 15% to 18%, while complete breech is lower at 4% to 6%, and frank breech is uncommon at 0.5%.

• History and Physical

During the physical exam, using the Leopold maneuvers, palpation of a hard, round, mobile structure at the fundus and the inability to palpate a presenting part in the lower abdomen superior to the pubic bone or the engaged breech in the same area, should raise suspicion of a breech presentation.

During a cervical exam, findings may include the lack of a palpable presenting part, palpation of a lower extremity, usually a foot, or for the engaged breech, palpation of the soft tissue of the fetal buttocks may be noted. If the patient has been laboring, caution is warranted as the soft tissue of the fetal buttocks may be interpreted as caput of the fetal vertex.

Any of these findings should raise suspicion and ultrasound should be performed.

Diagnosis of a breech presentation can be accomplished through abdominal exam using the Leopold maneuvers in combination with the cervical exam. Ultrasound should confirm the diagnosis.

On ultrasound, the fetal lie and presenting part should be visualized and documented. If breech presentation is diagnosed, specific information including the specific type of breech, the degree of flexion of the fetal head, estimated fetal weight, amniotic fluid volume, placental location, and fetal anatomy review (if not already done previously) should be documented.

• Treatment / Management

Expertise in the delivery of the vaginal breech baby is becoming less common due to fewer vaginal breech deliveries being offered throughout the United States and in most industrialized countries. The Term Breech Trial (TBT), a well-designed, multicenter, international, randomized controlled trial published in 2000 compared planned vaginal delivery to planned cesarean delivery for the term breech infant. The investigators reported that delivery by planned cesarean resulted in significantly lower perinatal mortality, neonatal mortality, and serious neonatal morbidity. Also, there was no significant difference in maternal morbidity or mortality between the two groups. Since that time, the rate of term breech infants delivered by planned cesarean has increased dramatically. Follow-up studies to the TBT have been published looking at maternal morbidity and outcomes of the children at two years. Although these reports did not show any significant difference in the risk of death and neurodevelopmental, these studies were felt to be underpowered. [8] [9] [10] [11]

Since the TBT, many authors since have argued that there are still some specific situations that vaginal breech delivery is a potential, safe alternative to planned cesarean. Many smaller retrospective studies have reported no difference in neonatal morbidity or mortality using these specific criteria.

The initial criteria used in these reports were similar: gestational age greater than 37 weeks, frank or complete breech presentation, no fetal anomalies on ultrasound examination, adequate maternal pelvis, and estimated fetal weight between 2500 g and 4000 g. In addition, the protocol presented by one report required documentation of fetal head flexion and adequate amniotic fluid volume, defined as a 3-cm vertical pocket. Oxytocin induction or augmentation was not offered, and strict criteria were established for normal labor progress. CT pelvimetry did determine an adequate maternal pelvis.

Despite debate on both sides, the current recommendation for the breech presentation at term includes offering external cephalic version (ECV) to those patients that meet criteria, and for those whom are not candidates or decline external cephalic version, a planned cesarean section for delivery sometime after 39 weeks.

Regarding the premature breech, gestational age will determine the mode of delivery. Before 26 weeks, there is a lack of quality clinical evidence to guide mode of delivery. One large retrospective cohort study recently concluded that from 28 to 31 6/7 weeks, there is a significant decrease in perinatal morbidity and mortality in a planned cesarean delivery versus intended vaginal delivery, while there is no difference in perinatal morbidity and mortality in gestational age 32 to 36 weeks. Of note, due to lack of recruitment, no prospective clinical trials are examining this issue.

• Fetal anomalies
• Fetal death
• Grand multiparity
• Multiple pregnancies
• Oligohydramnios
• Pelvis Anatomy
• Preterm labor
• Primigravida
• Uterine anomalies
• Pearls and Other Issues

In light of the decrease in planned vaginal breech deliveries, thus the decrease in expertise in managing this clinical scenario, it is prudent that policies requiring simulation and instruction in the delivery technique for vaginal breech birth are established to care for the emergency breech vaginal delivery.

• Enhancing Healthcare Team Outcomes

A breech delivery is usually managed by an obstetrician, labor and delivery nurse, anesthesiologist and a neonatologist. The ultimate decison rests on the obstetrician. To prevent complications, today cesarean sections are performed and experienced with vaginal deliveries of breech presentation is limited. For healthcare workers including the midwife who has no experience with a breech delivery, it is vital to communicate with an obstetrician, otherwise one risks litigation if complications arise during delivery.

INTRODUCTION

This topic will provide an overview of major issues related to breech presentation, including choosing the best route for delivery. Techniques for breech delivery, with a focus on the technique for vaginal breech delivery, are discussed separately. (See "Delivery of the singleton fetus in breech presentation" .)

TYPES OF BREECH PRESENTATION

● 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.

When viewing this topic in a different language, you may notice some differences in the way the content is structured, but it still reflects the latest evidence-based guidance.

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.

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. [1] Cunningham F, Gant N, Leveno K, et al. Williams obstetrics. 21st ed. New York: McGraw-Hill; 1997. [2] Kish K, Collea JV. Malpresentation and cord prolapse. In: DeCherney AH, Nathan L, eds. 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.

What Is Breech?

When a fetus is delivered buttocks or feet first

• Types of Presentation

Risk Factors

Complications.

Breech concerns the position of the fetus before labor . Typically, the fetus comes out headfirst, but in a breech delivery, the buttocks or feet come out first. This type of delivery is risky for both the pregnant person and the fetus.

This article discusses the different types of breech presentations, risk factors that might make a breech presentation more likely, treatment options, and complications associated with a breech delivery.

Verywell / Jessica Olah

Types of Breech Presentation

During the last few weeks of pregnancy, a fetus usually rotates so that the head is positioned downward to come out of the vagina first. This is called the vertex position.

In a breech presentation, the fetus does not turn to lie in the correct position. Instead, the fetus’s buttocks or feet are positioned to come out of the vagina first.

At 28 weeks of gestation, approximately 20% of fetuses are in a breech position. However, the majority of these rotate to the proper vertex position. 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.

Signs of Breech

There are no specific symptoms associated with a breech presentation.

Diagnosing breech before the last few weeks of pregnancy is not helpful, since the fetus is likely to turn to the proper vertex position before 35 weeks gestation.

A healthcare provider may be able to tell which direction the fetus is facing by touching a pregnant person’s abdomen. However, an ultrasound examination is the best way to determine how the fetus is lying in the uterus.

Most breech presentations are not related to any specific risk factor. However, certain circumstances can increase the risk for breech presentation.

These can include:

• Previous pregnancies
• Multiple fetuses in the uterus
• An abnormally shaped uterus
• Uterine fibroids , which are noncancerous growths of the uterus that usually appear during the childbearing years
• Placenta previa, a condition in which the placenta covers the opening to the uterus
• Preterm labor or prematurity of the fetus
• Too much or too little amniotic fluid (the liquid that surrounds the fetus during pregnancy)
• Fetal congenital abnormalities

Most fetuses that are breech are born by cesarean delivery (cesarean section or C-section), a surgical procedure in which the baby is born through an incision in the pregnant person’s abdomen.

In rare instances, a healthcare provider may plan a vaginal birth of a breech fetus. However, there are more risks associated with this type of delivery than there are with cesarean delivery. 

Before cesarean delivery, a healthcare provider might utilize the external cephalic version (ECV) procedure to turn the fetus so that the head is down and in the vertex position. This procedure involves pushing on the pregnant person’s belly to turn the fetus while viewing the maneuvers on an ultrasound. This can be an uncomfortable procedure, and it is usually done around 37 weeks gestation.

ECV reduces the risks associated with having a cesarean delivery. It is successful approximately 40%–60% of the time. The procedure cannot be done once a pregnant person is in active labor.

Complications related to ECV are low and include the placenta tearing away from the uterine lining, changes in the fetus’s heart rate, and preterm labor.

ECV is usually not recommended if the:

• Pregnant person is carrying more than one fetus
• Placenta is in the wrong place
• Healthcare provider has concerns about the health of the fetus
• Pregnant person has specific abnormalities of the reproductive system

Recommendations for Previous C-Sections

The American College of Obstetricians and Gynecologists (ACOG) says that ECV can be considered if a person has had a previous cesarean delivery.

During a breech delivery, the umbilical cord might come out first and be pinched by the exiting fetus. This is called cord prolapse and puts the fetus at risk for decreased oxygen and blood flow. There’s also a risk that the fetus’s head or shoulders will get stuck inside the mother’s pelvis, leading to suffocation.

Complications associated with cesarean delivery include infection, bleeding, injury to other internal organs, and problems with future pregnancies.

A healthcare provider needs to weigh the risks and benefits of ECV, delivering a breech fetus vaginally, and cesarean delivery.

In a breech delivery, the fetus comes out buttocks or feet first rather than headfirst (vertex), the preferred and usual method. This type of delivery can be more dangerous than a vertex delivery and lead to complications. If your baby is in breech, your healthcare provider will likely recommend a C-section.

A Word From Verywell

Knowing that your baby is in the wrong position and that you may be facing a breech delivery can be extremely stressful. However, most fetuses turn to have their head down before a person goes into labor. It is not a cause for concern if your fetus is breech before 36 weeks. It is common for the fetus to move around in many different positions before that time.

At the end of your pregnancy, if your fetus is in a breech position, your healthcare provider can perform maneuvers to turn the fetus around. If these maneuvers are unsuccessful or not appropriate for your situation, cesarean delivery is most often recommended. Discussing all of these options in advance can help you feel prepared should you be faced with a breech delivery.

• 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.

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.

Classifications

Types of breech presentation

Baby's buttocks lead the way into the birth canal

Hips are flexed, knees are extended, and the feet are in close proximity to the head

65% to 70% of breech babies are in this position.

Baby presents with buttocks first

Both the hips and the knees are flexed; the baby may be sitting cross-legged.

One or both of the baby's feet lie below the breech so that the foot or knee is lowermost in the birth canal

This is rare at term but relatively common with premature fetuses.

Common Vignette

Other Presentations

Epidemiology

33% of births less than 28 weeks' gestation

14% of births at 29 to 32 weeks' gestation

9% of births at 33 to 36 weeks' gestation

Clinical exam

Palpation of the abdomen to determine the position of the baby's head

Palpation of the abdomen to confirm the position of the fetal spine on one side and fetal extremities on the other

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 ]

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 ]

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 ]

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 ]

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 ]

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

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.

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).

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

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 ]

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 ]

6.1 Breech presentation

Presentation of the feet or buttocks of the foetus.

6.1.1 The different breech presentations

• In a complete breech presentation, the legs are tucked, and the foetus is in a crouching position (Figure 6.1a).
• In a frank breech presentation, the legs are extended, raised in front of the torso, with the feet near the head (Figure 6.1b).
• In a footling breech presentation (rare), one or both feet present first, with the buttocks higher up and the lower limbs extended or half-bent (Figure 6.1c).

6.1.2 Diagnosis

• The cephalic pole is palpable in the uterine fundus; round, hard, and mobile; the indentation of the neck can be felt.
• The inferior pole is voluminous, irregular, less hard, and less mobile than the head.
• During labour, vaginal examination reveals a “soft mass” divided by the cleft between the buttocks, with a hard projection at end of the cleft (the coccyx and sacrum).
• After rupture of the membranes: the anus can be felt in the middle of the cleft; a foot may also be felt.
• The clinical diagnosis may be difficult: a hand may be mistaken for a foot, a face for a breech.

6.1.3 Management

Route of delivery.

Before labour, external version (Chapter 7, Section 7.7 ) may be attempted to avoid breech delivery.

If external version is contra-indicated or unsuccessful, the breech position alone – in the absence of any other anomaly – is not, strictly speaking, a dystocic presentation, and does not automatically require a caesarean section. Deliver vaginally, if possible – even if the woman is primiparous.

Breech deliveries must be done in a CEmONC facility, especially for primiparous women.

Favourable factors for vaginal delivery are:

• Frank breech presentation;
• A history of vaginal delivery (whatever the presentation);
• Normally progressing dilation during labour.

The footling breech presentation is a very unfavourable position for vaginal delivery (risk of foot or cord prolapse). In this situation, the route of delivery depends on the number of previous births, the state of the membranes and how far advanced the labour is.

During labour

• Monitor dilation every 2 to 4 hours. 
• If contractions are of good quality, dilation is progressing, and the foetal heart rate is regular, an expectant approach is best. Do not rupture the membranes unless dilation stops.
• If the uterine contractions are inadequate, labour can be actively managed with oxytocin.

Note : if the dilation stales, transfer the mother to a CEmONC facility unless already done, to ensure access to surgical facility for potential caesarean section.

At delivery

• Insert an IV line before expulsion starts.
• Consider episiotomy at expulsion. Episiotomy is performed when the perineum is sufficiently distended by the foetus's buttocks.
• Presence of meconium or meconium-stained amniotic fluid is common during breech delivery and is not necessarily a sign of foetal distress.
• The infant delivers unaided , as a result of the mother's pushing, simply supported by the birth attendant who gently holds the infant by the bony parts (hips and sacrum), with no traction. Do not pull on the legs.

Once the umbilicus is out, the rest of the delivery must be completed within 3 minutes, otherwise compression of the cord will deprive the infant of oxygen. Do not touch the infant until the shoulder blades appear to avoid triggering the respiratory reflex before the head is delivered.

• Monitor the position of the infant's back; impede rotation into posterior position.

Figures 6.2 - Breech delivery

6.1.4 Breech delivery problems

Posterior orientation.

If the infant’s back is posterior during expulsion, take hold of the hips and turn into an anterior position (this is a rare occurrence).

Obstructed shoulders

The shoulders can become stuck and hold back the infant's upper chest and head. This can occur when the arms are raised as the shoulders pass through the mother's pelvis. There are 2 methods for lowering the arms so that the shoulders can descend:

1 - Lovset's manoeuvre

• With thumbs on the infant's sacrum, take hold of the hips and pelvis with the other fingers.
• Turn the infant 90° (back to the left or to the right), to bring the anterior shoulder underneath the symphysis and engage the arm. Deliver the anterior arm.
• Then do a 180° counter-rotation (back to the right or to the left); this engages the posterior arm, which is then delivered.

Figures 6.3 - Lovset's manoeuvre

6.3c  - Delivering the anterior arm and shoulder

2 - Suzor’s manoeuvre

In case the previous method fails:

• Turn the infant 90° (its back to the right or to the left).
• Pull the infant downward: insert one hand along the back to look for the anterior arm. With the operator thumb in the infant armpit and middle finger along the arm, bring down the arm (Figure 6.4a).
• Lift infant upward by the feet in order to deliver the posterior shoulder (Figure 6.4b).

Figures 6.4 - Suzor's manoeuvre

6.4b  - Delivering the posterior shoulder

Head entrapment

The infant's head is bulkier than the body, and can get trapped in the mother's pelvis or soft tissue.

There are various manoeuvres for delivering the head by flexing it, so that it descends properly, and then pivoting it up and around the mother's symphysis. These manoeuvres must be done without delay, since the infant must be allowed to breathe as soon as possible. All these manoeuvres must be performed smoothly, without traction on the infant.

1 - Bracht's manoeuvre

• After the arms are delivered, the infant is grasped by the hips and lifted with two hands toward the mother's stomach, without any traction, the neck pivoting around the symphysis.
• Having an assistant apply suprapubic pressure facilitates delivery of the aftercoming head.

2 - Modified Mauriceau manoeuvre

• Infant's head occiput anterior.
• Kneel to get a good traction angle: 45° downward.
• Support the infant on the hand and forearm, then insert the index and middle fingers, placing them on the infant’s maxilla. Placing the index and middle fingers into the infant’s mouth is not recommended, as this can fracture the mandible.
• Place the index and middle fingers of the other hand on either side of the infant's neck and lower the infant's head to bring the sub-occiput under the symphysis (Figure 6.6a).
• Tip the infant’s head and with a sweeping motion bring the back up toward the mother's abdomen, pivoting the occiput around her symphysis pubis (Figure 6.6b).
• Suprapubic pressure on the infant's head along the pelvic axis helps delivery of the head.
• As a last resort, symphysiotomy (Chapter 5, Section 5.7 ) can be combined with this manoeuvre.

Figures 6.6 - Modified Mauriceau manoeuvre

6.6a - Step 1 Infant straddles the birth attendant's forearm; the head, occiput anterior, is lowered to bring the occiput in contact with the symphysis.

6.6b  - Step 2 The infant's back is tipped up toward the mother's abdomen.

3 - Forceps on aftercoming head

Continuing Education Activity

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. This activity reviews the cause and pathophysiology of breech presentation and highlights the role of the interprofessional team in its management.

Objectives:

• Describe the pathophysiology of breech presentation.
• Review the physical exam of a patient with a breech presentation.
• Summarize the treatment options for breech presentation.
• Explain the importance of improving care coordination among interprofessional team members to improve outcomes for patients affected by breech presentation.

Introduction

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 fetus sitting with flexion of both hips and both legs in a tuck position. Finally, the incomplete breech can have any combination of one or both hips extended, also known as footling (one leg extended) breech, or double footling breech (both legs extended). [1] [2] [3]

Clinical conditions associated with breech presentation include those that may increase or decrease fetal motility, or affect the vertical polarity of the uterine cavity. Prematurity, multiple gestations, aneuploidies, congenital anomalies, Mullerian anomalies, uterine leiomyoma, and placental polarity as in placenta previa are most commonly associated with a breech presentation.  Also, a previous history of breech presentation at term increases the risk of repeat breech presentation at term in subsequent pregnancies. [4] [5] These are discussed in more detail in the pathophysiology section.

Epidemiology

Breech presentation occurs in 3% to 4% of all term pregnancies. A higher percentage of breech presentations occurs with less advanced gestational age. At 32 weeks, 7% of fetuses are breech, and 28 weeks or less, 25% are breech.

Specifically, following one breech delivery, the recurrence rate for the second pregnancy was nearly 10%, and for a subsequent third pregnancy, it was 27%. Prior cesarean delivery has also been described by some to increase the incidence of breech presentation two-fold.

Pathophysiology

As mentioned previously, the most common clinical conditions or disease processes that result in the breech presentation are those that affect fetal motility or the vertical polarity of the uterine cavity. [6] [7]

Conditions that change the vertical polarity or the uterine cavity, or affect the ease or ability of the fetus to turn into the vertex presentation in the third trimester include:

• Mullerian anomalies: Septate uterus, bicornuate uterus, and didelphys uterus 
• Placentation: Placenta previa as the placenta is occupying the inferior portion of the uterine cavity. Therefore, the presenting part cannot engage
• Uterine leiomyoma: Mainly larger myomas located in the lower uterine segment, often intramural or submucosal, that prevent engagement of the presenting part.
• Prematurity
• Aneuploidies and fetal neuromuscular disorders commonly cause hypotonia of the fetus, inability to move effectively
• Congenital anomalies:  Fetal sacrococcygeal teratoma, fetal thyroid goiter
• Polyhydramnios: Fetus is often in unstable lie, unable to engage
• Oligohydramnios: Fetus is unable to turn to vertex due to lack of fluid
• Laxity of the maternal abdominal wall: Uterus falls forward, the fetus is unable to engage in the pelvis.

The risk of cord prolapse varies depending on the type of breech. Incomplete or footling breech carries the highest risk of cord prolapse at 15% to 18%, while complete breech is lower at 4% to 6%, and frank breech is uncommon at 0.5%.

History and Physical

During the physical exam, using the Leopold maneuvers, palpation of a hard, round, mobile structure at the fundus and the inability to palpate a presenting part in the lower abdomen superior to the pubic bone or the engaged breech in the same area, should raise suspicion of a breech presentation.

During a cervical exam, findings may include the lack of a palpable presenting part, palpation of a lower extremity, usually a foot, or for the engaged breech, palpation of the soft tissue of the fetal buttocks may be noted. If the patient has been laboring, caution is warranted as the soft tissue of the fetal buttocks may be interpreted as caput of the fetal vertex.

Any of these findings should raise suspicion and ultrasound should be performed.

Diagnosis of a breech presentation can be accomplished through abdominal exam using the Leopold maneuvers in combination with the cervical exam. Ultrasound should confirm the diagnosis.

On ultrasound, the fetal lie and presenting part should be visualized and documented. If breech presentation is diagnosed, specific information including the specific type of breech, the degree of flexion of the fetal head, estimated fetal weight, amniotic fluid volume, placental location, and fetal anatomy review (if not already done previously) should be documented.

Treatment / Management

Expertise in the delivery of the vaginal breech baby is becoming less common due to fewer vaginal breech deliveries being offered throughout the United States and in most industrialized countries. The Term Breech Trial (TBT), a well-designed, multicenter, international, randomized controlled trial published in 2000 compared planned vaginal delivery to planned cesarean delivery for the term breech infant. The investigators reported that delivery by planned cesarean resulted in significantly lower perinatal mortality, neonatal mortality, and serious neonatal morbidity. Also, there was no significant difference in maternal morbidity or mortality between the two groups. Since that time, the rate of term breech infants delivered by planned cesarean has increased dramatically. Follow-up studies to the TBT have been published looking at maternal morbidity and outcomes of the children at two years. Although these reports did not show any significant difference in the risk of death and neurodevelopmental, these studies were felt to be underpowered. [8] [9] [10] [11]

Since the TBT, many authors since have argued that there are still some specific situations that vaginal breech delivery is a potential, safe alternative to planned cesarean. Many smaller retrospective studies have reported no difference in neonatal morbidity or mortality using these specific criteria.

The initial criteria used in these reports were similar: gestational age greater than 37 weeks, frank or complete breech presentation, no fetal anomalies on ultrasound examination, adequate maternal pelvis, and estimated fetal weight between 2500 g and 4000 g. In addition, the protocol presented by one report required documentation of fetal head flexion and adequate amniotic fluid volume, defined as a 3-cm vertical pocket. Oxytocin induction or augmentation was not offered, and strict criteria were established for normal labor progress. CT pelvimetry did determine an adequate maternal pelvis.

Despite debate on both sides, the current recommendation for the breech presentation at term includes offering external cephalic version (ECV) to those patients that meet criteria, and for those whom are not candidates or decline external cephalic version, a planned cesarean section for delivery sometime after 39 weeks.

Regarding the premature breech, gestational age will determine the mode of delivery. Before 26 weeks, there is a lack of quality clinical evidence to guide mode of delivery. One large retrospective cohort study recently concluded that from 28 to 31 6/7 weeks, there is a significant decrease in perinatal morbidity and mortality in a planned cesarean delivery versus intended vaginal delivery, while there is no difference in perinatal morbidity and mortality in gestational age 32 to 36 weeks. Of note, due to lack of recruitment, no prospective clinical trials are examining this issue.

Differential Diagnosis

• Face and brow presentation
• Fetal anomalies
• Fetal death
• Grand multiparity
• Multiple pregnancies
• Oligohydramnios
• Pelvis Anatomy
• Preterm labor
• Primigravida
• Uterine anomalies

Pearls and Other Issues

In light of the decrease in planned vaginal breech deliveries, thus the decrease in expertise in managing this clinical scenario, it is prudent that policies requiring simulation and instruction in the delivery technique for vaginal breech birth are established to care for the emergency breech vaginal delivery.

Enhancing Healthcare Team Outcomes

A breech delivery is usually managed by an obstetrician, labor and delivery nurse, anesthesiologist and a neonatologist. The ultimate decison rests on the obstetrician. To prevent complications, today cesarean sections are performed and experienced with vaginal deliveries of breech presentation is limited. For healthcare workers including the midwife who has no experience with a breech delivery, it is vital to communicate with an obstetrician, otherwise one risks litigation if complications arise during delivery.
