Could multiple surgeries make you more likely to wake up during an operation?

This study aims to find out if people who have had general anesthesia many times (more than 20) are at higher risk of a frightening experience called 'awareness with recall,' where a patient wakes up and remembers events during surgery. Researchers will survey and review the medical charts of up to 1,000 patients to compare those with many surgeries to those with few. The goal is to identify high-risk patients so doctors can improve anesthesia safety and comfort.
