ABSTRACT
BACKGROUND: Inhalation anesthetics are an important factor for postoperative hepatic and renal dysfunction. In this regard, TIVA can reduce the risk of hepatic and renal dysfunction inherited to inhalation anesthetics. The present study was conducted to determine whether hepatic and renal functions differ after anesthesia with sevoflurane and propofol. METHODS: Two hundred patients, ASA physical status class I, II, scheduled for an elective thyroidectomy were randomly divided into two groups. Anesthesia was maintained with sevoflurane 1-2% and remifentanil in the sevoflurane group (Group S) and propofol 2-5 ug/ml and remifentanil 2-5 ng/ml at the effect site, using a target controlled infusion (TCI) pump in the TIVA group (Group T) to maintain BIS of 40-60. To evaluate the hepatic and renal function, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and creatinine were tested at preoperation (baseline), postoperative 1 day and 3 days. RESULTS: AST was increased at postoperative 1 day and 3 days, compared with that of the preoperation in Group S, and postoperative 1 day in Group T, but the values were within its normal limit. ALT was not changed after anesthesia in both groups. BUN was increased at postoperative 1 day, compared with that of the preoperation in Group S, but the value was within its normal limit. Creatinine was not changed after anesthesia in both groups. CONCLUSIONS: The changes of hepatic and renal function after inhalation anesthesia with sevoflurane and TIVA with propofol and remifentanil for thyroidectomy were clinically insignificant, and there was no difference between the two methods.

The objective of the present study was to investigate the effect of administration of 1 mM methylene blue (MB) in drinking water for 30 days on hepatic and renal antioxidant status in female adult Wistar strain rats (n=5). MB failed to induce significant change in any of the measured antioxidant defence parameters namely, superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH). However, a marginally significant (P<0.05) increase in the level of lipid peroxidation (LPx) was recorded in liver, while a reduction (P<0.05) in its level in the kidney was noticed. Serum alanine amino transferase (AlaAT) and creatinine levels significantly (P<0.001) decreased in MB treated rats without any change in blood urea nitrogen (BUN) level. Our findings suggest that the effect of MB as administered in the present study was tissue specific with regard to the level of LPx, however, in general, it does not impair liver and kidney functions as evidenced by serum parameters.
ABSTRACT
@#ObjectiveTo investigate the remote renal injury after liver ischemia-reperfusion(I/R) and the renal protection afforded by propofol.Methods 72 male SD rats were randomly divided into three groups:normol control group, I/R group and propofol group .The animals were killed after 60 minutes ischemia of liver followed by reperfusion for 4 h,2 h. Blood urea nitrogen (BUN) and creatinine (Cr) were detected,and renal histopathologic lesion were observed.ResultsIn I/R group,the serum level of BUN and Cr increased significantly compared with the baseline before liver I/R,while propofol could decrease the serum level of BUN and Cr significantly.ConclusionPropofol can reduce the renal injury during liver I/R.
