A randomized double-blind trial was conducted over 48 hours comparing the effectiveness of prostaglandin E2 gel administered intracervically with that of demoxytocin buccal tablets for induction of labor in 103 patients with unripe cervical status (Bishop score 5 or less). A statistically significant difference was found in success frequency between the two groups, both on the first day (54.7 and 34.0%, respectively) and on the second day (82.0 and 61.9%, respectively; P less than .05). Without being matched, variables influencing the course of labor in the two groups were comparable. There was no statistically significant difference in the induction-delivery interval between the two groups during the first and second days of the trial. In both the prostaglandin E2 and the demoxytocin groups, patients who had not gone into labor during the first day showed a statistically significant increment in the Bishop score on the morning of the second day (2.4 and 1.3, respectively; P less than .01). The frequency of instrumental deliveries and cesarean section was the same in both groups; neither hypertonic uterine contractions nor side effects were observed in any patient. It is concluded that prostaglandin E2 gel administered intracervically is particularly well suited for the induction of labor in patients with unripe cervical status because of its combined contraction-inducing and cervical-ripening properties. |
