Continuous renal replacement therapies: Anticoagulation in the critically ill at high risk of bleeding

Abstract

Non-anticoagulation CRRT allowed an adequate filter life in most patients with a high risk of bleeding for prolonged aPTT and/or thrombocytopenia. Despite concerns regarding the need for careful monitoring, regional anticoagulation with heparin and protamine can be considered as a safe and valid alternative when non-anticoagulation is unsuitable because of early filter failure.
