title: Management of twin pregnancy: the vaginal route is still safe.
abstract: To investigate the effect of method of delivery on the outcome of twin pregnancies, we reviewed all deliveries at our institution over the 10 years from 1976 to 1985. Two hundred six pairs were delivered, with a mean gestational age of 34 weeks (range 20 to 43 weeks) and a mean weight of 2116 gm (range 220 to 3800 gm). The mean gestational age at diagnosis of the twin pregnancy was 23 weeks. Nineteen (4.6%) infants were stillborn, and 36 (8.7%) died in the neonatal period. Cesarean section was used to deliver both twins in 66 cases. The method of delivery for the remaining 142 cases was vaginal-vertex, 85 (61%), vaginal-breech, 40 (29%), cesarean section, 13 (9%), and version and extraction, 2 (1%). The four most common indications for cesarean section for both twins were previous cesarean section, breech presentation, abnormal labor, and fetal distress. The indications for the 13 cesarean sections after vaginal delivery of twin A were fetal distress, cord prolapse, high presenting part, and footling breech. The impact of the method of delivery was investigated by comparing outcome variables between twin pairs. No significant differences were noted for perinatal mortality, need for resuscitation, duration of newborn hospital stay, and trauma. There were significant differences in the 1- and 5-minute Apgar scores in the vaginal delivery group. These differences were clinically minor, tending toward mild acidemia, and were unaffected by route or method of delivery.
