Intraperitoneal Ketamine Versus Fentanyl as Adjuvants to Bupivacaine in Laparoscopic Cholecystectomy
84 participantsStarted 2026-08-01
Plain-language summary
Laparoscopic cholecystectomy is the standard surgical treatment for gallbladder stones; however, the origin of pain after LC is multifactorial and complex in nature. Pain arising from incision sites is parietal pain, whereas pain from the gall bladder bed is mainly visceral in nature, and shoulder pain is mainly referred owing to the residual carbon dioxide irritating the diaphragm. Intraperitoneal administration of local anesthetics has been shown to improve postoperative pain control and reduce the need for systemic analgesics. The addition of adjuvant agents such as fentanyl or ketamine may further enhance analgesic efficacy. This randomized double-blind study aims to compare the effectiveness of intraperitoneal ketamine versus fentanyl as adjuvants to bupivacaine in reducing postoperative pain and analgesic requirements following laparoscopic cholecystectomy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
