Comparative study of local anesthetics in laparoscopic cholecystectomy: skin VS sheath infiltration

Abstract

     Laparoscopic cholecystectomy is the standard treatment of cholecystectomy nowadays. This technique becomes a popular procedure, compare with open technique, due to small incision, less postoperative pain, early ambulation and decrease length of hospital stay. This comparative study started January 1st, 2020 to June 30th, 2020. Sixty patients undergo laparoscopic cholecystectomy were randomized into two groups, 30 patients each. In the first, we infiltrated local anesthetic agent through trochar site before incision. The second, we infiltrated local anesthetic agent at trochar site after finished the operation and the specimen was removed. A pain scale was used and recorded their pain intensity at 6 and 12 hours, postoperatively. Dose of postoperative morphine administration and time-toambulation were also assessed. Statistic analysis in this study are descriptive statistics, chi-square and T-test.

     Result: No significant statistic in demographic data of this two groups. The pain intensity at 6 and 12 hours, postoperatively, analgesics requirement and time-to-ambulation were statistic significantly lower in the preoperative trochar site injection compared with the other group.
