NCT ID NCT07671755
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at two antibiotic treatments for ventilator-associated pneumonia caused by a multidrug-resistant bacteria. Researchers compared giving patients just colistin versus colistin plus cefoperazone-sulbactam. They measured how well patients improved clinically and on chest X-rays. The trial included 80 adults with this specific infection.

- What this could lead to
- If the combination works better, it could offer a more effective treatment option for this hard-to-treat lung infection.
- What could go wrong
