Induction of labor with prostaglandin E2 vaginal suppositories.
A prospective randomized study of 85 parturients was undertaken comparing the safety and efficacy of a 3-mg prostaglandin E2 vaginal suppository with intravenous oxytocin for the induction of labor. All patients were required to have a Bishop's score of 5 or higher. Labor was successfully induced in 98% of the patients in both groups by their respective methods. Sixty-four percent of the patients receiving a 3-mg prostaglandin E2 suppository required no intravenous oxytocin. More specifically, 82% (23/28) of the parous patients but only 29% (5/17) of the nulliparous patients who received a single 3-mg prostaglandin E2 suppository for labor induction did not require oxytocin augmentation (P less than .005). The first and second stages of labor were not significantly different for the two groups, and there was no significant difference in the incidence of cesarean section. A 3-mg prostaglandin E2 vaginal suppository may be a useful alternative to oxytocin for the induction of labor in carefully selected patients.
