Vaginal delivery under caudal analgesia after caesarean section and other major uterine surgery.

In the absence of a recurring indication for caesarean section vaginal delivery in subsequent pregnancy is a "trial of scar," with potentially serious implications for mother and baby. Labour under caudal analgesia was carefully supervised for 75 women with a surgically scarred uterus-due to lower segment section in 72, abdominal hysterotomy in one, and transcavity myomectomy in two. Every caesarean scar was assessed digitally during labour and every uterus was examined after delivery. Caudal analgesia provided a painless labour and delivery and made scar assessment easy. Controlled intravenous Syntocinon infusion was given to 25 patients. One scar dehiscence occurred early in labour and one in the second stage. Seventy mothers had 71 vaginal deliveries with one pair of twins and one breech. There was one stillbirth and no neonatal death. There were five repeat sections.
