Oral misoprostol vs. vaginal gemeprost prior to surgical termination of pregnancy in nulliparae

Abstract

Background. To compare the efficacy and side-effects of intravaginal gemeprost with those of oral misoprostol for cervical ripening prior to first-trimester pregnancy termination in nulliparous women. Methods. Retrospective analysis of surgical terminations of pregnancy performed before 90 days of gestation. Intravaginal gemeprost 1 mg or oral misoprostol 800 μg was administered 2 h before the procedure. Results. In total, 746 women were enrolled into the study, 84 received intravaginal gemeprost and 662 oral misoprostol. Median baseline cervical dilatation was significantly greater in women who received misoprostol before the operation than in those who received gemeprost (7 mm vs. 3 mm; p < 0.0001). The incidence of fever, vomiting and diarrhea was not different between the two groups. The incidence of abdominal pain with request for pain medication, emergency admission to operating room due to vaginal bleeding, hospital stay longer than 24 h and surgical repair of cervical injury due to Hegar dilatation was significantly higher among the gemeprost group than the misoprostol group. Conclusions. In cervical priming prior to first-trimester pregnancy termination in nulliparous women, oral misoprostol is more effective and is associated with fewer side-effects and complications than intravaginal gemeprost. © Acta Obstet Gynecol Scand 83 2004.
