To determine whether injection of bupivacaine at the level of the parietal peritoneum around surgical port sites reduces postoperative pain following laparoscopic cholecystectomy.
Randomized, prospective, double-blind study involving 80 patients undergoing laparoscopic cholecystectomy.
Patients were allocated to standard subcutaneous periportal bupivacaine (20 ml, 0.5%; n = 40) or subcutaneous (20 ml, 0.25%) plus parietal peritoneal bupivacaine injection (20 ml, 0.25%; n = 40).
Pain scores at rest and on movement were evaluated 6 and 18 hours after surgery using a visual analogue scale.
Median pain scores were significantly lower with peritoneal injection at 6 hours for both rest (1.0 vs 3.0) and movement (2.9 vs 5.0).
At 18 hours, median pain scores remained significantly lower in the peritoneal group at rest (0 vs 1.9) and on movement (1.2 vs 3.2).
Opiate and oral analgesic requirements were lower in the peritoneal injection group, though the difference did not reach statistical significance.
