First seen Mar 20, 2026 · Last updated May 24, 2026 · Updated 9 times
Summary
This study tests whether a mild electrical pulse to a nerve in the ear, given during heart surgery, can lower the chances of postoperative delirium (sudden confusion) and reduce anxiety or depression after the operation. About 270 adults having planned heart surgery will be randomly assigned to receive either the real stimulation or a sham (fake) version. The goal is to see if this simple, non-drug approach can help patients recover with a clearer mind and better mood.
