Randomized Controlled TrialPost-laparoscopic cholecystectomy pain: effects of intraperitoneal local anesthetics on pain control--a randomized prospective double-blinded placebo-controlled trial.
Postoperative pain after laparoscopic cholecystectomy (LC) is generally less than open cholecystectomy; however, the postoperative shoulder and abdominal pain experienced by patients still causes preventable distress. Intraperitoneal irrigation of the diaphragmatic surface and gallbladder fossa using normal saline, bupivacaine, or lignocaine may effectively control visceral abdominal pain after an LC. Two hundred patients with similar demographics undergoing elective LC were randomized to one of four groups of 50 patients each, including Group A placebo control, Group B with isotonic saline irrigation, Group C with bupivacaine irrigation, and Group D with lignocaine irrigation. ⋯ Bowel function recovery was similar in all patients, and there were no significant complications. We conclude that intraperitoneal irrigation with either saline, bupivacaine, or lignocaine can significantly reduce visceral abdominal pain after LC. Lignocaine was the most efficacious local anesthetic in this trial and has a high safety profile when used at recommended doses.
