Long fasting times may raise confusion risk after surgery
NCT ID NCT07391631
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the time patients fast before and after surgery is linked to postoperative delirium—a state of confusion that can slow recovery. Researchers will track fasting durations and check for delirium in 1,000 adults having surgery. No new treatments are given; the goal is to gather information to improve fasting guidelines and patient safety.
