An Observational Prospective Study of Anesthetic Sensitivity Assessed by Alpha Band Power and Its Association With Emergence Time From Sevoflurane General Anesthesia in Young Adults.
Sponsor: University of Chile
Summary
The goal of this observational study is to determine the relationship between brain activity patterns and recovery time in adult patients (ages 35-50, ASA I-II) undergoing elective general anesthesia. The main question it aims to answer is: \- Does a lower magnitude of intraoperative alpha wave power correlate with a longer time for patients to emerge from general anesthesia? Participants will: * Undergo a standardized general anesthesia (GA) protocol for elective surgery. * Have their EEG activity recorded using a standard clinical BIS™ anesthetic depth monitor during the procedure. * Have their time to awakening precisely measured after the cessation of anesthetic gases.
