%X OBJECTIVE: To compare maternal and neonatal outcomes between oxytocin and vaginal misoprostol induction in women with term prelabor rupture of membranes (PROM) and unfavorable cervixes.
METHODS: In this retrospective study, 589 pregnant women with term singleton fetuses in cephalic presentation, reactive nonstress tests, PROM of 2-24 h duration, Bishop score <6, and no previous uterine surgery were reviewed and divided into oxytocin (n = 301) and misoprostol (n = 288) groups. The primary outcomes were the rate of vaginal delivery and delivery within 24 h.
RESULTS: After 24 h of induction, the misoprostol group showed a significantly higher proportion of vaginal delivery (64.6% vs. 49.5%, P < 0.001) and a lower cesarean section delivery rate (11.5% vs. 25.2%, P < 0.001) than the oxytocin group. More primiparas in the misoprostol group achieved vaginal delivery within 24 h than in the oxytocin group (60.5% vs. 45.4%, P = 0.001). Among primiparas, the misoprostol group had a significantly lower cesarean delivery rate (12.6% vs. 27.5%, P < 0.001).
CONCLUSIONS: Vaginal misoprostol induction in term PROM gravidas with unfavorable cervixes was associated with lower cesarean section and higher vaginal delivery rates within 24 h than oxytocin infusion. Vaginal misoprostol and oxytocin infusion had similar maternal and neonatal outcomes.
