ABSTRACT
The effect of different doses of ulinastatin on cellular immunity and hepatorenal functions in patients undergoing laparoscopic colorectal-carcinoma surgery was observed and analyzed. The 200 patients with laparoscopic colorectal-carcinoma surgery in our hospital were selected as research subjects and divided into 4 groups containing equal patients, namely, saline group, 0.5 x 104U/kg ulinastatin group, 1 x 104U/kg ulinastatin group, and 1.5 x 104U/kg
ulinastatin group, which were denoted as group A, group B, group C and group D, respectively. The treatment effect of patients in 4groups was observed and compared. By observing the Narcotrend cerebral state index [NT index], the results showed that NT index at tracheal intubation, pneumoperitoneum beginning, pneumoperitoneum 30min, resection of tumor, end of operation in 4 groups was significantly lower than that at preoperative anesthesia [T0] [p<0.05];
differences in hepatorenal values [AST, ALT, BUN and Cr] among 4 groups at T0 were of no statistical significance [P > 0.05]; each index in T cell subsets in the postoperative third days [T1] was significantly lower than that at T0; indexes of T cell subgroup of group B, C and D at T1 were higher than that of group A at T1 [p<0.05]. For 4 groups, the difference in liver and kidney function indicators at T1 and T0 was of no statistical significance, p>0.05. Different doses of ulinastatin have a certain effect on cellular immunity in patients undergoing laparoscopic colorectal-carcinoma surgery and do not significantly affect hepatorenal function
