New study tests if waiting for the placenta before clamping the cord benefits mothers and babies
NCT ID NCT07713277
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This study compares two approaches to umbilical cord clamping after vaginal birth: standard delayed clamping (waiting 1–3 minutes) versus waiting until the placenta is naturally expelled before clamping. The goal is to see which method leads to better outcomes for both mother and baby, including blood loss, need for phototherapy, and newborn weight changes. About 2,000 healthy mothers with single, full-term pregnancies will take part.
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 this trial shows that waiting to clamp the cord until after the placenta is delivered is safe and beneficial, it could change standard childbirth practices to improve newborn iron levels and reduce complications.
- What could go wrong
- This is an observational study comparing two existing practices, not a test of a new drug or device. Results may show no clear advantage, and the risk of postpartum hemorrhage or retained placenta must be carefully weighed.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Singleton pregnancy (≥34+0 weeks of gestation). * Spontaneous eutocic vaginal delivery. * Healthy newborn with a birth weight of ≥2500 grams (appropriate for gestational age). * Informed consent signed by both the patient and her partner. Exclusion Criteria: * Maternal Medical Conditions * Chronic or Pregnancy-Induced Hypertensive Disorders: Including chronic hypertension, pre-eclampsia, and HELLP syndrome. * Systemic Diseases: Pre-existing autoimmune diseases, significant cardiovascular diseases, or metabolic disorders that may interfere with placental function. * Haematological Disorders: Known maternal coagulopathies, severe anaemia (Haemoglobin \< 8 g/dL), or other blood dyscrasias. * Obstetric Complications and Emergencies * Placental Anomalies: Suspected or confirmed placental abruption, placenta previa, or morbidly adherent placenta (accreta/increta/percreta). * Acute Intrapartum Complications: Umbilical cord prolapse, suspected chorioamnionitis (intra-amniotic infection), or significant antepartum haemorrhage. * Operative or Instrumental Delivery: Any requirement for urgent operative vaginal delivery (vacuum or forceps) or conversion to Emergency Caesarean Section. * Pre-existing Risk for PPH: History of severe Postpartum Haemorrhage in previous pregnancies. * Neonatal Factors * Acute Neonatal Distress: Requirement for immediate neonatal resuscitation at birth that precludes waiting for placental expulsion. * Congenital Anomalies: Presence of major congenital malformations or chromosomal abnormalities.
