Vaginal delivery was successful in 76% of the 242 women who underwent a trial of labor after cesarean section in a prior pregnancy. Separation of the uterine scar occurred in four women (1.7%). Women whose prior cesarean section was for breech presentation had the highest rate of successful vaginal delivery (86%). The vaginal delivery rates were similar in women who delivered infants with birth weights > or = 4,000 g (73%) and < 4,000 g (76%). The use of epidural anesthesia and oxytocin may enhance the success of vaginal delivery in women undergoing a trial of labor following an earlier cesarean section.
在242名曾有剖宫产史且此次接受剖宫产后试产的女性中，76%的女性阴道分娩成功。4名女性（1.7%）发生子宫瘢痕分离。既往剖宫产指征为臀位的女性阴道分娩成功率最高（86%）。分娩出生体重≥4000g婴儿的女性阴道分娩率（73%）与分娩出生体重<4000g婴儿的女性相似（76%）。硬膜外麻醉和缩宫素的使用可能会提高既往有剖宫产史且此次接受试产的女性阴道分娩的成功率。
