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.

Conditions

  • Emergence From Anesthesia
  • EEG Power Spectra

Interventions

PROCEDURE

Intraoperative EEG Recording

Patients will be monitored with a frontal EEG during general anesthesia using the BIS Monitor to calculate alpha power
