Research progress of the mechanism of hepatic injury after cardiopulmonary bypass / 医学研究生学报

ABSTRACT

Since the first launching of heart lung bypass machine in animal model in 1937,cardiopulmonary bypass(CPB) has become more and more consummate,but it still brings about many complications,including pulmonary,renal and hepatic dysfunctions.Among these complications,hepatic dysfunction plays an important role in the impairment after cardiac operations.The liver function indices such as aspartate aminotransferase,glutamate-pyruvate transaminase,bilirubin and alkaline phosphatase will step up obviously during 3 to 5 days after the operation.The physiological changes deteriorate patient's condition,and even influence the prognosis.This clinical phenomenon puzzles cardiac surgeons.All these demand us to answer the following questions Is the cardiopulmonary bypass harm the liver? What's the mechanism? We review the different researches on hepatic injury after cardiopulmonary bypass.
