NCT ID NCT07665645
First seen Jun 24, 2026 · Last updated Jun 24, 2026
Summary
This study looked at how different types of anesthesia affect thinking and memory after surgery in 90 obese patients. Patients received either low-flow sevoflurane gas, normal-flow sevoflurane gas, or total intravenous anesthesia with propofol and remifentanil. Their cognitive function was tested before surgery, 30 minutes after, and on the third day after surgery. The goal is to find out which method might be best for protecting brain function in obese patients.
