Background. Coagulation system disorders in liver transplantation (ltx) patients are considered a serious issue. Liver cirrhosis leads to decreased synthesis of clotting factors and decreased elimination of waste products, including coagulation proteins. Platelet sequestration and dysfunction in an enlarged spleen additionally worsen these conditions. The resulting state, the most common pathology of the coagulation system, involves the reduction of clotting potential and hyperfibrinolysis.
Objectives. Tackling the problem of impaired hemostasis is a dynamic process. Throughout the whole procedure, consisting of the preanhepatic, the anhepatic and the neohepatic phases, consecutive pathomechanisms disrupt the very balance that anesthesia aims to preserve.
Material and Methods. Rotational thromboelastometry (ROTEM), having been introduced in the Clinic of Anesthesiology and Intensive Therapy, Wroclaw Medical University, Poland, enables the efficient and early diagnosis of clotting disorders. An additional major problem which occurs during ltx, namely blood loss, could be solved using a cell separator.
Results. In this study, we present the standards introduced to the Transplantology Department of the Vascular Surgery Clinic, Wroclaw Medical University, Poland, that describe blood treatment during ltx procedures.
Conclusion. We conclude that thromboelastometric examination and the use of a cell separator have significantly increased the safety of ltx procedures at our clinic. The introduction of thromboelastometry (TEM) and the implementation of the cell separator recovery method have enabled us to perform the dangerous and complicated surgical procedure of ltx in a much more stable and much safer manner than in the past.
