Summary

This study looks at whether noise in the operating room changes how deeply patients are asleep during surgery and affects their heart rate and blood pressure. Researchers will measure noise levels and compare them to standard monitoring data from 70 adults having elective surgery under general anesthesia. The goal is to understand if quieter rooms could improve patient safety.
