When to clamp the cord? study tests waiting for pulsations to stop
NCT ID NCT03844490
First seen Jun 24, 2026 · Last updated Jul 10, 2026 · Updated 2 times
Summary
This study looked at 580 low-risk pregnant women and their newborns to compare clamping the umbilical cord 1-3 minutes after birth versus waiting until the cord stops pulsating on its own. The goal was to see if waiting longer affects newborn jaundice, hemoglobin levels, or mother's health. The findings could help guide standard delivery practices.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If waiting for cord pulsation to stop is safe, it could become a standard practice to improve newborn iron levels without extra risk.
- What could go wrong
- This is a completed study, not a treatment trial. Results may not change current guidelines, and individual birth situations may still require early clamping.
