New trial could change how doctors help CDH babies at birth
NCT ID NCT04429750
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a simple change at birth: instead of clamping the umbilical cord right away, doctors will keep it intact while helping the baby breathe. The goal is to see if this improves heart and lung function in full-term infants with congenital diaphragmatic hernia (CDH), a rare defect where the diaphragm doesn't form properly. About 180 babies will take part across multiple hospitals.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- procedure (delayed cord clamping with intact cord resuscitation)
- What this could lead to
- If it works, this could improve breathing and survival for newborns with a rare birth defect affecting the diaphragm.
- What could go wrong
- This is a mid-stage trial with 180 babies, so results may not apply to all cases. The procedure may not improve outcomes and could increase bleeding risk for the mother.
