NCT01276392

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Filter life time of continuous renal replacement therapy

    Filter life time measured in hours of duration of continuos renal replacement therapy, filter life time end, when system clotts.

    Individual time point, standardized

    beginning of hemodialysis, 1,2,4,12,24,28,72 hours after start of hemodialysis

Study Arms (2)

Heparin

10 Patients undergoing continuous renal replacement therapy using heparin for providing anticoagulation. Blood samples taken at 8 predefined timepoints.

CiCa

10 Patients undergoing continuous renal replacement therapy using citrate for providing anticoagulation. Blood samples taken at 8 predefined timepoints.
