Cardiac surgery; Hemostatic profile; Regional citrate anticoagulation; Renal replacement therapy

Introduction: This work is focused on mapping issues of hemostasis in patients during continuous renal replacement therapy, or the possible impact of the use of anticoagulants. Methods: The study included 30 consecutive patients requiring continuous renal replacement therapy following cardiac surgery in the period of 2009 to 2012. Patients were placed into 2 branches according to the selected method of anticoagulation (regional citrate anticoagulation-RCA, unfractionated heparin UFH). According to the given scheme (t1-t7) thromboelastography and laboratory testing related to the testing of blood clotting during continuous renal replacement therapy were performed.
