Background: Although a laparoscopic cholecystectomy results in less pain than an open cholecystectomy, it is not a pain-free procedure. Therefore, this study was conducted to determine whether perioperative intravenous lidocaine would reduce postoperative pain after a laparoscopic cholecystectomy.
Methods: Fifty patients undergoing laparoscopic cholecystectomy were divided into two groups; a lidocaine group, in which patients were injected with a lidocaine bolus (1.5 mg/kg) and infusion (1.5 mg/kg/h); and a control group, in which patients were injected with the same volume of saline bolus and infusion. Intravenous lidocaine was initiated before anesthesia was administered and continued for 1 hour postoperatively. The intensity of abdominal and shoulder pain was then assessed 1, 6, 12 and 24 hours after surgery and recorded using a visual analog pain score (VAS) and verbal rating score (VRS).
Results: The abdominal pain score (VAS and VRS) was significantly lower in the lidocaine group than in the control group at all times evaluated during the first 24 hours after surgery (P ＜ 0.05). In addition, the shoulder pain score and incidence were significantly lower in the lidocaine group than the control group at 12 hours and 24 hours after surgery (P ＜ 0.05). In the lidocaine group, the incidences of epigastric, right flank, and back pain were lower than that of the control group, but these differences were not statistically significant.
Conclusion: Perioperative intravenous lidocaine reduces shoulder and abdominal pain for 24 hours after laparoscopic cholecystectomy. (Korean J Anesthesiol 2008; 54: 69∼73)
