AbstractDuring orthotopic liver transplanatation haemostasis is often disturbed and coagulation monitoring is mandatory. We compared the results obtained by whole blood prothrombin time and activated partial thromboplastin time assays (Hemochron) and thrombelastometry (ROTEM) 05) with laboratory coagulation assays (prothrombin time, activated partial prothrombin time, fibrinogen, and platelet count) in samples obtained during orthotopic liver transplantations. Determination of prothrombin time and activated partial prothrombin time using the Hemochron device showed good correlation with laboratory coagulation assays (r = 0.912, p < 0.001, and r = 0.794, p < 0.001). Maximum clot firmness as determined by thrombelastometry correlated well with platelet count (r = 0.779, p < 0.001) and, to a lesser degree, with fibrinogen concentration (r = 0.590, p < 0.001). During orthotopic liver transplantation, prothrombin time and activated partial prothrombin time can be reliably determined by the Hemochron device, while thrombelastometry allows assessment of platelet count and fibrinogen concentration.
