IntroductionDuring liver transplantation, continuous laboratory monitoring of complex changes of the hemostatic system is necessary. The aim of this study was to compare two methods of monitoring: standard coagulation tests and rotational thromboelastometry.Material And MethodsThe study included 17 patients who had undergone orthotopic liver transplantation in the Clinical Centre of Vojvodina, Serbia in the period from June 2008 to October 2012. The coagulation parameters (platelet count, activated partial thromboplastin time, prothrombin time and fibrinogen level) were compared with the thromboelastometric parameters (coagulation time, clot formation time and maximal clot firmness).ResultsThe results showed a statistically significant correlation between the platelet count and maximum clot firmness of the intrinsically (r=0.51, p<0.001) and extrinsically activated thromboelastometric assays (r=0.64, p<0.001). The fibrinogen level and maximum clot firmness of the fibrinogen thromboelastometric test correlated significantly as well (r=0.44, p=0.002). No significant correlations were found among the activated partial thromboplastin time, prothrombin time, coagulation time and clot formation time.ConclusionFor an adequate perioperative monitoring of the dynamic intraoperative hemostatic changes and the optimal use of blood derivatives during liver transplantation, the combined application of standard coagulation tests and rotational thromboelastometry should be considered whenever possible.
