Comparison of Balanced General Anesthesia Protocols in Sleeve Gastrectomy Surgery with Respect to Postoperative Opioid Consumption.

Abstract

<h4>Purpose</h4>To evaluate the effects of two different anesthesia management techniques applied to sleeve gastrectomy patients on postoperative opioid consumption.<h4>Design</h4>Retrospective archival review observational study.<h4>Methods</h4>The hospital data management system scanned the files of 205 sleeve gastrectomy surgeries performed between June 2024 and March 2025. Patients who received fentanyl and/or ketamine as part of their standard anesthesia protocol and were managed with patient-controlled analgesia were included in the study.<h4>Findings</h4>The primary outcome measured in the study, opioid consumption, was significantly higher in the control group compared to the ketamine infusion group.<h4>Conclusions</h4>In patients with increased postoperative opioid consumption due to obesity, the addition of intraoperative ketamine infusion may be a viable option for balanced anesthesia management.
