Anesthesia and Postoperative Delirium in Older Adults Undergoing Hip Surgery

Abstract

General anesthesia has no distinct effect on incident postoperative delirium in older adults undergoing hip surgery. This also holds for individuals suffering from cognitive impairment or who are otherwise at risk for postoperative delirium. Perioperative use of narcotics, benzodiazepines, and anticholinergic agents was not associated with incident delirium in this cohort of older adults undergoing hip surgery.
