Comparison of Postoperative Morphine Requirements Between Two Magnesium Sulfate Administration Protocols in Opioid-Free Anesthesia for Bariatric Surgery
In Brief
An observational study for Postoperative Pain and 3 related conditions. Completed, enrolled 110 participants across 1 site.
Detailed Summary
This retrospective observational study aims to compare postoperative morphine consumption in patients undergoing bariatric surgery with opioid-free anesthesia (OFA) using two different intravenous magnesium sulfate administration protocols: a single bolus versus a bolus followed by continuous infusion. Medical records of 110 patients operated between June 2022 and December 2023 at Hospital HM Nou Delfos were reviewed. All patients received standardized OFA, and only the magnesium protocol varied between the groups. The primary objective was to evaluate total morphine consumption during the first 48 hours postoperatively. Secondary outcomes included pain scores, antiemetic use, and adverse events. This study was approved by the hospital's Research Ethics Committee (Protocol V3\_12.05.2025).
