Balloon vs drug: which is safer for inducing labor in overdue pregnancies?

NCT ID NCT02907060

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested two ways to soften the cervix (cervical ripening) in women with prolonged pregnancies (41+ weeks). One method uses a drug called Propess (dinoprostone), the other uses a soft balloon device placed in the cervix. The goal was to see which method leads to fewer C-sections due to signs of fetal distress. Over 1,200 women took part. The results could help doctors choose the safest approach for overdue babies.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
dinoprostone (Propess) and a double transcervical balloon (Cook Cervical Ripening Balloon)
What this could lead to
If the balloon works better, it could offer a safer, gentler way to start labor in overdue pregnancies, reducing emergency C-sections.
What could go wrong
This trial is already completed, so results are known. The balloon may not reduce C-sections as hoped, and both methods have risks like infection or uterine hyperstimulation.
