First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if using a balloon to start labor for only 3 hours instead of the usual 12 can shorten the time from induction to birth by at least 6 hours. About 280 pregnant women with a single baby in head-down position will take part. The goal is to speed up delivery without increasing C-sections or risks to mother or baby.
