Summary

This study compares light versus deep general anesthesia in older adults (65+ or Indigenous 55+) having major surgery. The goal is to see if lighter anesthesia reduces delirium—sudden confusion—and long-term memory problems. About 2,766 participants will be randomly assigned to one of two anesthesia levels, guided by a brain monitor. If effective, this simple change could help millions of seniors stay mentally sharp after surgery.
