Breech infants: vaginal or cesarean delivery?

Area of Science:

• Obstetrics and Gynecology
• Neonatal Care
• Perinatal Medicine

Background:

• Determining optimal delivery mode for singleton term breech infants is crucial.
• Vaginal delivery versus elective cesarean section presents distinct risks and benefits.
• Maternal and neonatal outcomes require careful consideration for breech presentations.

Purpose of the Study:

• To compare planned vaginal delivery with elective cesarean section for singleton term breech infants.
• To evaluate neonatal mortality and morbidity based on delivery mode.
• To assess postpartum maternal morbidity in relation to delivery method.

Main Methods:

• Study included 388 singleton term breech infants born in a Vienna teaching hospital.
• Deliveries were categorized into planned vaginal (72%) and scheduled cesarean (28%).
• Neonatal outcomes (Apgar score, umbilical artery pH) and maternal morbidity were compared.

Main Results:

• Vaginally delivered breech infants of primiparas had significantly lower five-minute Apgar scores and umbilical artery pH compared to abdominally delivered infants.
• No significant differences in Apgar scores or umbilical artery pH were observed between delivery modes for multiparas.
• Postpartum maternal morbidity showed no significant difference between the vaginal and cesarean delivery groups.

Conclusions:

• Planned vaginal delivery for singleton term breech infants of primiparas is associated with poorer neonatal outcomes.
• Singleton term breech infants of multiparas do not appear to benefit from cesarean delivery.
• Delivery mode decisions for breech presentations should consider parity and potential neonatal risks.
