The Effect of 0.5% Bupivacaine Instillation for the Postoperative Pain after Laparoscopic Cholecystectomy / 대한마취과학회지

ABSTRACT

BACKGROUND: Although post operative pain has been reduced significantly since the advent of laparoscopic surgery, many patients still complain of moderate abdominal and shoulder pain after surgery. METHOD: Patients scheduled for elective laparoscopic cholecystectomy were assigned to three groups by simple randomization(12 patients per group). Group I patients(control) had no specific treatment, group II patients had 10 ml of normal saline instillation, and group III patients had 10 ml of 0.5% bupivacaine instillation. Instillation was made directly into the gallbladder bed and right subdiaphragmatic space under direct vision by the surgeon at the end of the procedure and before evacuating the pneumoperitoneum. RESULT: Compared to that of the group I, VAS of group II and III did not show any statistically significant difference. Compared to the group I, group II & III showed no significant difference in numbers of requests of Tiaprofenic acid during the 36hours after the surgery. CONCLUSION: Topical instillation of 0.5% bupivacaine 10 ml to the gallbladder bed and right subdiaphragmatic space after laparoscopic cholecystectomy is not effective for the post operative pain control.
