Stopping routine inhaled nitric oxide during newborn stabilization for congenital diaphragmatic hernia

Official title: Inhaled Nitric Oxide (iNO) for Congenital Diaphragmatic Hernia (CDH) - The "NoNO Trial" - a Multi-center, De-implementation, Stepped-wedge, Cluster-randomized Trial Within an Established Collaborative

Run by The University of Texas Health Science Center, Houston · NCT05213676 · Data updated 2026-11-12

This study will test whether stopping inhaled nitric oxide during initial resuscitation helps newborns with CDH avoid extracorporeal life support (ECLS) or death.

Is this trial a fit for you?

Likely a good fit

Live-born newborns with Bochdalek congenital diaphragmatic hernia diagnosed within the first month of life who are born at or transferred to a participating CDH Study Group center within one week.

Probably not a fit

Babies diagnosed after one month, those with Morgagni hernia, those transferred to a participating center after one week, or those without potential access to iNO are not expected to benefit from this de-implementation approach in this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this multicenter stepped-wedge cluster-randomized study, participating centers will follow their usual inhaled nitric oxide (iNO) protocols and then crossover at randomized times to de-implement iNO during the immediate postnatal resuscitation/stabilization period. The primary outcome is a composite of ECLS use and/or mortality, with secondary analyses of ECLS, mortality, oxygenation, and an economic analysis of incremental health system costs per prevented ECLS use or death. Eligible patients are live-born neonates with Bochdalek CDH diagnosed within the first month of life who are born at or transferred to a participating center within one week. Outcomes will be compared across clusters before and after de-implementation to determine clinical and cost effects.

Why it matters

Potential benefit: If successful, stopping routine iNO during initial stabilization could reduce ECLS use and deaths and lower health-system costs.

How similar studies have gone: Prior randomized data have not shown clear benefit of iNO for CDH and routine use is controversial, so de-implementing iNO is a relatively novel, evidence-driven approach supported by observational concerns about iNO effectiveness.
