Abstract:
Patients with acute kidney injury are generally prothrombotic, and as such prone to increased risk of clotting in extracorporeal renal replacement therapy (RRT) circuits. Although some patients may be adequately treated by intermittent RRT, however due to cardiovascular instability many patients are treated by continuous renal replacement therapy (CCRT) or prolonged intermittent renal replacement therapy (PIRRT). Clotting in the RRT circuit not only reduces the efficiency of solute clearances, affects fluid balance, but also has economic health care costs. The longer duration RRT modes, CRRT and PIRRT are more prone to clotting, and more dependent on adequate anticoagulation. This review will compare the currently available systemic and regional anticoagulation options for CRRT and PIRRT for the patient with acute kidney injury.
