Effect of Opioid-Free Versus Opioid Anesthesia on the Quality of Postoperative Recovery in Patients Receiving Laparoscopic Sleeve Gastrectomy

OFA significantly improved postoperative recovery quality as evidenced by higher QOR-15 scores, reduced postoperative nausea and vomiting (PONV), lower pain scores and decreased opioid requirements compared to OBA. Although duration of awakening from anesthesia was prolonged, OFA demonstrated superior recovery outcomes and fewer complications supporting its clinical utility in obese patients undergoing laparoscopic sleeve gastrectomy.
