Can lower anesthesia gas flow help patients and the planet?
NCT ID NCT07465146
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 97 women having gynecologic surgery to compare two ways of giving anesthesia gas (sevoflurane): minimal flow and metabolic flow. Researchers checked how these methods affected body temperature, blood pressure, and heart rate during surgery. They also measured how much gas was used and its cost, aiming to reduce waste and harm to the environment.
