Shock therapy? no, just a gentle tingle to ease ERCP sedation risks

This study tests whether a gentle electrical current applied to specific points on the skin (called TEAS) can reduce side effects like low oxygen or blood pressure during a procedure to treat bile duct problems (ERCP). About 130 adults will be randomly assigned to receive either real TEAS or a fake version, while all get standard sedation. The goal is to see if TEAS makes the procedure safer and more comfortable, and to understand how it works in the body.
