This randomized clinical trial compared intraperitoneal irrigation of bupivacaine(a local anesthetic) vs a control group receiving normal saline for relief of post operative pain following laparoscopic gallbladder surgery. A total of 106 patients divided into two equal groups, with one group receiving bupivacaine and the other treated using normal saline(control).Previous studies on the subject found that bupivacaine significantly reduced postoperative pain. Although conventional intravenous analgesics remain widely used, bupivacaine may be a better option, especially in difficult surgical cases.
