About this trial

This is a single-center, randomized, double-blind, placebo-controlled, parallel-group proof-of-concept study to evaluate the analgesic efficacy and safety of omega-3 fatty acids as an adjunct to morphine for acute postoperative pain following laparoscopic cholecystectomy.

Patients will receive either omega-3 fatty acid supplementation or a placebo before and after surgery. At the end of surgery, a loading dose of morphine of 0.04 mg/kg body weight will be administered intravenously as a bolus in both groups. The primary endpoint will be the total amount of rescue morphine used during the first 24 postoperative hours.
