[Misoprostol and oxytocin for induction of cervical ripening and labor in patients with term pregnancy and premature membrane rupture].

Objective: To evaluate the effect of the concurrent administration of intravaginal misoprostol and oxytocin for cervical ripening and labor induction on length labor, mode of delivery and perinatal outcomes.

Patients And Methods: One hundred seven patients with singleton pregnancy at term, vertex presentations, premature rupture of membranes and Bishop scores of < or = 4 were randomly assigned to receive one of three treatments: Group I: Intravenous oxytocin plus intravaginal misoprostol (n = 36); Group II: Intravenous oxytocin plus placebo intravaginal (n = 34); Group III: Intravaginal misoprostol plus intravenous placebo. The time interval from induction to beginning of the labor, from induction to delivery, mode of delivery and perinatal outcomes were measured.
