title: Delivery of the second twin.
abstract: A retrospective chart review of all twin deliveries between April 1, 1977, and March 20, 1980, at the Boston City Hospital and the Brigham and Women's Hospital revealed corrected neonatal mortality rates of 0 for 74 twins in nonvertex presentation delivered by cesarean section and 0 for 76 second-born twins extracted vaginally. Breech extraction of 76 second-born twins weighing more than 1499 g at birth was not associated with a statistically significant increase in the incidence of 5-minute Apgar scores of 7 or less when compared to 74 similarly asymptomatic twins in nonvertex presentation delivered by cesarean section. Vaginal delivery may be considered when the second twin, weighing more than 1500 to 2000 g, is in breech presentation.
