Objective: To compare the efficacy and safety of cervical ripening and induction of labor with prostaglandin E1 among primiparas, multiparas and grand multiparas.
Study design: This was a retrospective cohort study.
Results: Between January and December 2017, 1713 women underwent cervical ripening and induction of labor with prostaglandin E1: 523 were primiparas, 656 were multiparas, and 534 were grand multiparas. Four hundred and seventy-nine (91.6%) primiparas delivered vaginally as did 640 (97.6%) multiparas and 521 (97.6%) grand multiparas. Forty-four (8.4%) primiparas underwent cesarean delivery compared to 16 (2.4%) multiparas and 13(2.4%) grand multiparas. Induction to delivery interval was significantly longer in primiparas (29.7 ± 22.8 h). There were no cases of uterine rupture, and the rates of postpartum hemorrhage and endometritis were similar among the three groups. Neonatal outcomes including Apgar score < 7 and umbilical artery pH < 7.1 were not significantly different between the groups.
Conclusion: Using prostaglandin E1 for cervical ripening and labor induction is efficient and safe in primiparas, multiparas and grand multiparas.
