Study on hemostatic and coagulative variations during orthotopic liver transplantation / 中华器官移植杂志

ABSTRACT

Objective To investigate the hemostatic and coagulative variations during orthotopic liver transplantation (OLT).Method The blood platelet count, coagulant and anti-coagulant functions were assessed pre- and intra-operation of OLT.Results During the operation, activated partial thromboplastin time (aPTT) and prothrombin time (PT) were prolonged, platelet count (PLT), activities of most of the coagulation factors and levels of antithrombin (AT), plasminogen (PLG), plasminogen activator inhibitor-1 (PAI-1) and ?2 -antiplasmin (?2-AP) were reduced, while the levels of tissue plasminogen activator (t-PA), plasmin-?2-antiplasmin complex (PAP) and thrombin-antithrombin complex (TAT) were increased. The variations in the neohepatic phase were more significant than that in the pre-operation phase. Conclusion In the entire process of OLT operation, the coagulant and anti-coagulant functions were decreased, and the fibrinolytic functions were sthenic in the anhepatic phase and the neohepatic phase.
