EVALUATION OF A PROTOCOL FOR SELECTING FETUSES IN BREECH PRESENTATIONFOR VAGINAL DELIVERY OR CESAREAN-SECTION

OBJECTIVE: Our purpose was to evaluate, with respect to obstetric inte rvention and neonatal outcome, a protocol for selecting fetuses in bre ech presentation for vaginal delivery or cesarean section. STUDY DESIG N: A clinical follow-up study was performed between 1984 and 1992 of a ll term singleton deliveries in breech presentation. Each case selecte d for vaginal delivery had a matched control in vertex presentation. R ESULTS: A total of 1212 infants presented as breech. Vaginal delivery increased from 45% to 57% (p = 0.004), and cesarean section for failur e of vaginal delivery declined from 21% to 6% (p < 0.00001). None, how ever, died or had long-term sequelae because of a complicated or faile d vaginal breech delivery. A total of 8.8% of those delivered vaginall y in breech versus 5.0% of those in vertex presentation were admitted to the neonatal intensive care unit (p = 0.009). Among those with vagi nal delivery, 2.5% in breech presentation were given the clinical diag nosis of birth asphyxia versus none in the vertex position (p = 0.0001 ). CONCLUSION: Breech presentation at term may be selected for vaginal delivery if properly managed.
