Summary

This study tests whether breathing in a safe, inexpensive gas called argon during carotid artery surgery can prevent brain damage and confusion after the operation. About 100 adults having elective carotid surgery will be randomly assigned to receive either argon gas or a placebo alongside standard anesthesia. The goal is to see if argon can reduce the risk of silent strokes and postoperative delirium, which are common after these procedures.
