dc.description.abstractThis article seeks to standardize an experimental model of liver ischemia-reperfusion in rats following hemorrhagic shock modulated by N-acetylcysteine (NAC). Twenty-seven adult Wistar rats were randomized into three groups: the HS-IR-Garm underwent hemorrhagic shock with selective hepatic ischemia followed by reperfusion; the HSIR + NAC-G, the same procedure plus NAC; and the control group, only venous catheterization. Blood was withdrawn for 10 minutes until MABP reached 35 mm Hg, which was maintained for 1 hour. the blood was then reinjected as required to maintain MABP at that level. Ringer's lactate solution was infused in a volume equivalent to three times the shed blood, over a period of 15 minutes. Half of the shed blood was reinfused over 5 minutes. HSIR + NAC-G received 150 mg/kg of NAC, during treatment of the shock, and again 10 minutes before reperfusion and continued for 30 minutes. Finally, both groups were subjected to 40 minutes of warm selective hepatic ischemia and reperfusion for 1 hour. Data were analyzed by nonparametric tests (P less than or equal to .05). Liver enzyme levels were higher in HS-IR-G (DHL = 6094 +/- 1688, AST = 746 +/- 175, and ALT = 457 +/- 90) than in HSIR + NAC-G group (DHL = 2920 +/- 284, AST = 419 +/- 113, and ALT = 253 +/- 26). the values in the control group were lower than both experimental groups (DHL 965 +/- 173, AST = 163 +/- 42, and ALT = 82 +/- 28). Our data showed that liver ischemia-reperfusion injury following hemorrhagic shock produces important hepatic damage and that NAC reduces injury in this rat model.en
