ObjectiveThe aim was to evaluate the effect of oral administration of preoperative duloxetine on postoperative pain and total analgesic requirement in the postoperative period as the primary objective. The secondary objective was to evaluate the perioperative hemodynamic parameters, sedation scores, demographic data, and incidence of side effects (if any) in patients undergoing laparoscopic cholecystectomy.Materials And MethodsThis was a prospective, randomized, double-blind, placebo-controlled study conducted in a tertiary level medical college on 60 patients of either sex posted for laparoscopic cholecystectomies with American Society of Anesthesiologists (ASA) I and II. The patients were divided into 2 groups (n=30), the patients were given duloxetine 60 mg capsules and placebo capsules (Becosules) 2 hours before surgery.ResultsThe total requirement for both first and second rescue analgesics was higher in placebo as compared with duloxetine and was found to be significant ( P <0.05). The difference in mean visual analog scale score was significantly ( P <0.001) higher in placebo as compared with duloxetine at all-time intervals postoperatively 0 minute (7.6±0.7 vs. 4.6±0.8); 15 minutes (5.9±0.8 vs. 4.2±1.0); 30 minutes (4.4±0.5 vs. 3.6±0.9); 4 hours (6.6±0.06 vs. 5.3±1.3); 8 hours (5.2±1.2 vs. 3.9±1.0); and 12 hours (5.1±1.3 vs. 2.3±0.7). The mean arterial blood pressure and heart rate were significantly higher in placebo compared with duloxetine in most of the time intervals in the perioperative period. There was no significant difference in the sedation score between the groups except the 30 minutes and 8 hours postoperative.DiscussionPreoperative oral duloxetine during laparoscopic cholecystectomy could reduce postoperative pain, postoperative analgesic requirements, and better optimization of hemodynamics without causing major side effects.Copyright © 2022 Wolters Kluwer Health, Inc.
