Abstract:
Objective To evaluate the effect of sevoflurane on liver injury in a pig model of hemorrhagic shock.Methods Twenty-four Bama miniature pigs of both sexes,weighing 20-25 kg,aged 3-5 months,were equally randomized into 3 groups using a random number table:sham operation group (group S);hemorrhagic shock group (group HS);sevoflurane group (group Sev).Hemorrhagic shock was induced by withdrawing 40％ of blood volume from the right femoral artery within 15 min (30 ml/kg) in HS and Sev groups.The animals inhaled 2％ sevoflurane for 30 min after establishment of the model in group Sev.Before hemorrhagic shock (T0),and at 30,60,90,120,180 and 240 min after hemorrhagic shock (T1-6),blood samples were collected from the femoral artery for determination of plasma alaninc aminotransferase (ALT) and betaine-homocysteine S-methyltransferase (BHMT) concentrations (by enzymelinked immunosorbent assay).After blood sampling at T6,the animals were sacrificed,and the right lobes of livers were removed for examination of the pathological changes with light microscope.Results Compared with group S,the plasma ALT concentrations were significantly increased at T4-6,the plasma BHMT concentrations were significantly increased at T3-6 (P＜0.05),and significant liver pathological changes were observed in HS and Sev groups.Compared with group HS,the plasma ALT concentrations were significantly decreased at T4-6,the plasma BHMT concentrations were significantly decreased at T3-6 (P＜0.05),and the liver pathological changes were significantly attenuated in group Sev.Conclusion Sevoflurane can mitigate liver injury in a pig model of hemorrhagic shock.
