Abstract

Nineteen patients received prostaglandin E2 as a 2.5 mg gel (seven cases), 3.3 mg chip (five cases), or 10 mg controlled-release pessary (seven cases) for preinduction cervical ripening. Blood flow velocities did not change significantly for the uterine arcuate artery, fetal aorta, and umbilical artery circulations after any of the treatments. In no case did systolic/diastolic ratios consistently elevate above baseline values.
