Which PEEP level saves preemie lungs? major trial seeks answer
NCT ID NCT04372953
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two ways of giving breathing support (PEEP) to very premature babies right after birth. One method uses a steady pressure, the other starts high then lowers it. The goal is to see which approach reduces the chance of death or chronic lung disease. Over 900 babies born between 23 and 28 weeks are taking part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Positive End-Expiratory Pressure (PEEP) via CPAP or ventilation
- What this could lead to
- If it works, this could identify the best way to support premature babies' breathing at birth, potentially reducing death or long-term lung disease.
- What could go wrong
- This is a large trial but still early-stage for clinical practice. The two PEEP strategies may show no clear difference, and results may not apply to all preterm infants.

Inclusion Criteria: * Infants born between 23 weeks 0 days and 28 weeks 6 days PMA (by best obstetric estimate). * Receives respiratory intervention (resuscitation) at birth with CPAP and/or positive pressure ventilation in the Delivery Room, to support transition and/or respiratory failure related to prematurity. * Has a parent or other legally acceptable representative capable of understanding the informed consent document and providing consent on the participant's behalf either prospectively or after birth and randomisation if prenatal consent was not possible (at sites where the Ethics Committee permits waiver of prospective consent). Exclusion Criteria: * Not for active care based on assessment of the attending clinician or family decision * Anticipated severe pulmonary hypoplasia due to rupture of membranes \<22 weeks with anhydramnios or fetal hydrops * Major congenital anomaly or anticipated alternative cause for respiratory failure * Refusal of informed consent by their legally acceptable representative * Does not have a guardian who can provide informed consent.
