Abruptio placentae associated with misoprostol use in women with preeclampsia.

OBJECTIVE

To evaluate complications associated with cervical ripening with vaginal administration of misoprostol and dinoprostone vaginal inserts in women with preeclampsia. preeclampsia.

STUDY DESIGN

Retrospective study of patients with preeclampsia undergoing cervical ripening with vaginal misoprostol and dinoprostone vaginal inserts prior to labor induction.

RESULTS

Among 203 patients with preeclampsia undergoing cervical ripening prior to induction, 95 received vaginal misoprostol, and 108 received dinoprostone. The incidence of uterine hyperstimulation requiring medical therapy and the need for emergency cesarean section due tofetal heart rate abnormalities were significantly higher among patients receiving misoprostol (22.1% versus 12.0%, p = 0.04, and 17.9% versus 8.3%, p = 0.03, respectively). The overall incidence of abruptio placentae was 7.4%, with a significantly higher incidence among those receiving misoprostol as compared to dinoprostone (13.7% versus 1.9%, p = 0.001).

CONCLUSION

Among patients with preeclampsia undergoing cervical ripening prior to labor induction, there is a higher incidence of acute intrapartum complications (uterine hyperstimulation, cesarean section for fetal heart rate abnormalities and abruptio placentae) with vaginal misoprostol, as compared to dinoprostone, vaginal insert.
