Preinductive cervical ripening with prostaglandin E2 in women with one previous cesarean section

Thirty term pregnant women with one previous cesarean section and with unripe cervices were given 0.5 mg prostaglandin E2 in gel strictly intracervically for cervical ripening and labor induction. Fifteen out of these 30 women (50%) were vaginally delivered within 24 hours. The cervical ripening/labor induction was considered a failure in two women. In one woman, an episode of hypercontractility was registered. After tocolytic therapy the uterine activity was normalised and the woman had a normal vaginal delivery. The frequency of cesarean sections was 8/30 (27%). At the operations no insufficiencies in the uterine scars were noted. Conclusively, strict intracervical application of 0.5 mg prostaglandin E2 in gel can be used for cervical ripening and labor induction also in women with one previous cesarean section.
