New study tests if popping the last membrane gets labour going faster
NCT ID NCT07301957
First seen Jun 26, 2026 · Last updated Jul 02, 2026 · Updated 3 times
Summary
About 1 in 4 women have their water break before labour starts. Most go into labour within 48 hours, but some need to be induced. This study tests whether deliberately breaking the leftover membrane when a woman is admitted to the hospital can shorten the time to labour and reduce the need for induction. The trial will include 130 women with a single baby in head-down position.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- additional rupture of the residual membrane using a sterile amniotic membrane piercer (Robé device)
- What this could lead to
- If it works, this could reduce the time women wait for labour to start and lower the need for induced labour after their water breaks.
- What could go wrong
- This is a small, early-stage study with only 130 participants. It may not show a clear benefit, and the procedure carries a small risk of infection or discomfort.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Women over 18 years of age * Single foetal pregnancy, cephalic presentation * diagnosis of membrane rupture with persistence of one membrane and absence of immediate spontaneous labour. * Person affiliated with or beneficiary of a social security scheme * Free, informed and written consent signed by the participant and the investigator (no later than the day of inclusion and before any examination required by the research).
