Summary

This study looks at whether a specific brain activity pattern called burst suppression, seen when anesthesia first begins, is linked to how deep anesthesia stays during surgery. Researchers will monitor 200 adults having planned surgery with total intravenous anesthesia. The study only records information from standard monitoring and does not change any care patients receive.
