Oxygen chambers could save lives from Flesh-Eating bacteria
NCT ID NCT07489274
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This study tests whether adding hyperbaric oxygen treatment (breathing pure oxygen in a pressurized chamber) to standard care can lower the death rate in people with severe, fast-spreading soft-tissue infections. About 1,480 adults with surgically confirmed infection will be randomly assigned to receive either standard care alone or standard care plus hyperbaric oxygen. The main goal is to see if the oxygen treatment improves survival within 30 days.
