Study of Anesthesia Depth Variability and Its Impact on Recovery Quality After Elective Laparoscopic Gallbladder Surgery in Adults

What this Trial Is About

Researchers are studying how fluctuations in anesthesia depth during surgery, measured by bispectral index BIS monitoring, affect patients recovery quality after surgery. This observational study focuses on adults undergoing elective laparoscopic gallbladder removal under general anesthesia. The goal is to understand the relationship between BIS variability during anesthesia and changes in recovery quality as measured by a specific questionnaire. All participants will receive standard general anesthesia care with BIS monitoring as part of routine practice. BIS values will be recorded throughout the surgery without altering usual anesthesia management. Recovery quality will be assessed before surgery and again on the first day after surgery using the Quality of Recovery-15 QoR-15 questionnaire. Additional data like delirium screening and perioperative clinical information will also be collected. Participants will complete the QoR-15 questionnaire before surgery and on postoperative day one. Researchers will collect BIS data continuously during the procedure and record other clinical information. The main measure is the change in QoR-15 score from before surgery to the first postoperative day. Additional outcomes include postoperative delirium and pain intensity. The study does not involve interventions beyond routine care and aims to improve understanding of how anesthesia stability impacts recovery.
