Summary

This study looks at the best dose of a sedative called ciprofol for people having thyroid surgery. About 101 adults will receive this medicine to put them to sleep, and researchers will track how their brain activity changes. The goal is to find the exact amount needed for safe and effective anesthesia, and to see if a brain monitor can reliably measure sedation levels.
