NCT01276392
First received: January 12, 2011
Last updated: March 26, 2014

  Purpose

Actual clinical practice predominantly makes use of heparin (systemically) or citrate regionally as anticoagulation in the extracorporeal circulation for renal replacement therapy. We aim to find out if different anticoagulation strategies may lead to different levels of platelet activation and whole blood coagulation. Regarding coagulation activation, it remains uncertain if there is an advantage for one of these methods. However, it is of major interest to minimize the risk of any additional clotting activation via extracorporeal circulation in these usually critically ill patients.

Primary Outcome Measures:
  • Filter life time of continuous renal replacement therapy [ Time Frame: Individual time point, standardized ] [ Designated as safety issue: Yes ]
    Filter life time measured in hours of duration of continuos renal replacement therapy, filter life time end, when system clotts.


Secondary Outcome Measures:
  • Activation of coagulation [ Time Frame: beginning of hemodialysis, 1,2,4,12,24,28,72 hours after start of hemodialysis ] [ Designated as safety issue: No ]
    blood samples for multiplate, rotem and systemic coagulation paramters
