Can a simple gas help fragile newborns breathe easier?
NCT ID NCT07247240
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether inhaled nitric oxide can help newborns with a hole in their diaphragm (congenital diaphragmatic hernia) who also have high blood pressure in their lungs. About 40 babies will receive the gas, and doctors will check if their oxygen levels improve within 30 minutes. The goal is to see if this treatment can stabilize breathing and reduce the need for more intensive support.
