Can a simple gas stop pneumonia after heart surgery?
NCT ID NCT06162455
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether breathing in high-dose nitric oxide (NO) gas after heart surgery could prevent pneumonia. 74 patients who had heart surgery with a heart-lung machine were randomly assigned to receive either NO gas or a placebo (oxygen-air mixture) for 30 minutes twice a day for 5 days. The researchers measured how many patients developed pneumonia in each group.

What this could lead to
If it works, this could offer a simple way to prevent pneumonia after heart surgery, reducing complications and hospital stays.
