Coagulation changes and the influence of the early perfusate in the course of orthotopic liver transplantation (OLT) when aprotinin is used intra-operatively.
The changes in relevant haemostatic parameters during the course of ten orthotopic liver transplantation were studied when aprotinin was given intra-operatively. Increases of tissue-type (P = 0.008) and urokinase-type (P = 0.009) plasminogen activators during the anhepatic phase could be correlated with hyperfibrinolysis. Thrombin-antithrombin III complexes (TAT) increased after revascularization of the liver graft (P = 0.003). Parallel studies in the perfusate showed that TAT concentrations were 350% and protease inhibitor activities (antithrombin III, protein C) only 52% of the systemic circulation before reperfusion, suggesting that thrombin activation together with protease inhibitor consumption occurs during graft liver reperfusion. The relatively smaller increases in profibrinolytic parameters and a lower blood loss when compared with other groups may be explained by aprotinin administration in our patients.
