Abstract

Perioperative bleeding remains a major challenge in liver transplantation. We aimed to compare standard laboratory tests with thromboelastometry (ROTEM ® ) with regard to their ability to predict postoperative non-surgical bleeding. Data from 243 adult liver transplant recipients from January 2012 to May 2014 were evaluated retrospectively. Upon admission to the intensive care unit, coagulation status was assessed using standard laboratory tests [prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen concentration, and platelet count] and ROTEM ® whole blood coagulation assays. Bleeding was defined as transfusion of ≥ 3 units of red blood cells or reoperation for non-surgical bleeding within 48 h after transplantation. Coagulation test results were analysed using receiver operating characteristics (ROC) in order to identify variables predictive of postoperative bleeding. Coagulation management was based on ROTEM ® -guided factor concentrate treatment. The overall incidence of bleeding was 12.3% ( n =30). Twenty-three (9.5%) patients underwent reoperation and seven (2.9%) received ≥3 units of red blood cells and non-operative management. Standard laboratory tests predictive of postoperative bleeding were...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
