Efficacy of High-Volume Low-Concentration Intraperitoneal Bupivacaine Irrigation for Postoperative Analgesia in Patients Undergoing Laparoscopic Cholecystectomy: Bupivacaine Irrigation for Analgesia.

Intraperitoneal irrigation with a low-volume, high-concentration local anaesthetic in laparoscopic cholecystectomy (LC) provides less pain relief. We investigated the impact of high-volume, low-concentration bupivacaine on postoperative pain and opioid requirement. Patients undergoing LC were randomised into Group B (20 mL of 0.
