Summary:Ripening of the cervix by intravaginal application of a prostaglandin-containing gel is evaluated. Thirty patients with an unfavorable cervix needing labor induction were studied in a double-blind, prospective fashion. The prostaglandin gel proved superior to placebo in ripening the cervix (P less than .05), reducing induction failures (P less than .025), diminishing the oxytocin dosage necessary for induction (P less than .05), and lowering the rate of cesarean section (.05 less than P less than .1). One hundred fifty additional patients with varying Bishop scores and differing clinical situations were also studied. There were 35 cesarean sections (23.3%), nine failed inductions (6%), a spontaneous labor rate of 46%, and an average Bishop score change of 2.5. Twenty patients with premature rupture of the membranes and an unfavorable cervix received a modified gel containing 2.5 mg of prostaglandin E2. Average Bishop score change was 2.9, and there was a 55% incidence of spontaneous labor.
