Abstract Introduction Viscoelastic point-of-care diagnostics are crucial in cardiac surgery. In the FIBTEM assay of rotational thromboelastometry (ROTEM), guidelines suggest target maximum clot firmness values to reduce perioperative bleeding. The..

Abstract Background: Monitoring the anticoagulant effect of unfractionated heparin (UFH) in extracorporeal membrane oxygenation (ECMO) patients is complex but critically important to balance the risks of treatment related bleeding and..

Abstract Objectives Viscoelastic assays, such as rotational (ROTEM), are used increasingly in cardiac surgery to guide transfusion decisions. After separation from (CPB), achieving rapidly is the main goal before chest closure. The authors hypothesized..

Abstract Introduction We hypothesized that perioperative fibrinogen level, platelet count, and rotational thromboelastometry (ROTEM) data values decrease in proportion to cardiopulmonary bypass (CPB) time, particularly in patients who underwent deep..

Abstract Introduction: We aimed to investigate parameters for prediction of post-operative blood loss and re-operation in patients who underwent cardiopulmonary bypass. Methods: Thrombin generation assay, activated partial thromboplastin time, activated clotting time..

Abstract Background Each year in the UK, ≈3000 children undergo major cardiac surgery requiring cardiopulmonary bypass. Approximately 40 % of these experience excessive bleeding necessitating red cell transfusion or treatment with..

Abstract This retrospective, observational study compared the impact of a point-of-care rotational thromboelastometry (ROTEM®) method versus conventional bleeding management in terms of postoperative (24-h) blood loss, intraoperative and postoperative (24-h)..

Abstract Optimal anticoagulation monitoring in patients with extracorporeal membrane oxygenation (ECMO) is fundamental to avoid hemorrhagic and thromboembolic complications. Besides conventional coagulation tests, there is growing interest in the use..

Abstract In thromboelastometry (ROTEMTM) the difference in amplitude between the EXTEM and the FIBTEM is considered an index of platelet contribution to clot strength (PCSamp). The difference in elasticity (PCSel)..

Summary Thromboelastometry point‐of‐care coagulation testing facilitates optimised management of bleeding. Previous thromboelastometry systems required the blood sample and liquid reagents to be pipetted in several manual steps by trained personnel...
