Abstract

In this study, we aimed to evaluate the effects of different agents used for anesthesia maintenance on liver enzymes and lactate changes in patients undergoing laparoscopic cholecystectomy using CO2 pneumoperitoneum with constant pressure. Seventy-five patients planned to undergo laparoscopic cholecystectomy operation have been randomly divided into 3 groups. Liver function tests have been evaluated preoperatively and postoperatively in the 24th hour. Arterial blood samples for lactate level determination were obtained: (T_1) immediately before pneumoperitoneum, (T_2) 10 min after pneumoperitoneum, (T_3) 30 min after pneumoperitoneum, (T_4) 60 min after desufflation of CO2. Patients scheduled to undergo laparoscopic cholecystectomy operation. The possible effects of different agents used for anesthesia maintenance on liver enzymes and lactate changes in patients undergoing laparoscopic cholecystectomy. In comparison of lactate values, there were no differences between the three groups in T_1, T_2 and T_4 measurements (P=0.059, P=0.108, P=0.225). However, in the T_3 measurements, lactate values are lower in the Group P, compared to Group S and D (P=0.001, P=0.001). Postoperative AST and ALT values are lower in the Group P, compared to Group S and D (P
