Обзор
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.
Подробное описание
Currently, the most widely used drugs for treating post-surgical pain are opioids, such as morphine. Morphine works primarily by activating specific opioid receptors, providing significant pain relief but also causing side effects that limit its use.
Preclinical studies in our laboratory have shown that combined treatment with morphine and omega-3 fatty acids produces an additive enhancement of morphine's analgesic effect, mediated by the opioid pathway. Furthermore, we observed that this combined treatment prevents development of tolerance to morphine's analgesic effect and reduces some of the drug's adverse effects.
In order to reduce morphine dose and decrease or avoid morphine's side effects, the present study was designed to administer omega-3 fatty acids as an adjunct to morphine for acute postoperative pain following laparoscopic cholecystectomy.
Вмешательства
- Препарат Omega-3 fatty acids + Morphine group
The omega-3 fatty acids will be given twice before surgery (1680 mg/day) once on the day of surgery (840 mg) with 0,04 mg/kg morphine, and twice the day after surgery (1680 mg/day). It will be administered with lunch or dinner. - Другое Placebo+ Morphine group
The placebo will be given twice before surgery (1680 mg/day) once on the day of surgery (840 mg) with 0,04 mg/kg morphine, and twice the day after surgery (1680 mg/day). It will be administered with lunch or dinner.
