Study Completion Date: May 2008
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1 prostacyclin group
prostacyclin analogue (PGIA) used as circuit anticoagulant during continuous venovenous hemodiafiltration (CVVHDF) in acute kidney failure patients
Drug: prostacyclin
prostacyclin was infused as CRRT circuit anticoagulant into the arterial-line of the circuit at 4 ng/Kg/min
Other Name: prostacyclin epoprostenol (PGIA) (Flolan®, Glaxo-Wellcome)
Active Comparator: 2 heparin group
unfractionated heparin used as circuit anticoagulant during continuous venovenous hemodiafiltration (CVVHDF) in acute kidney failure patients
Drug: heparin
was prepared using our standard protocol: 2 ml of an already-stored solution containing 5000 IU/ml of UFH were diluted in 20 ml of saline obtaining a final concentration of 500 IU/ml, and infused pre-filter at 6 IU/Kg/h, according to the post-filter activated clotting time measured hourly, and adjusted to obtain a value between 180 and 200 sec.
Other Name: unfractionated heparin UFH (Liquemin®, Roche).

Detailed Description:
Context and purpose of the study: Prospective, randomized comparison of a PGIA versus UFH as circuit anticoagulant. Platelet responsiveness was assessed from peripheral blood by light-transmittance aggregometry (LTA) induced by collagen and ADP, at baseline, 4 and 24 hrs after treatment onset. Platelet function was also assessed in blood samples collected in the circuit before and after the filter. The Setting was a University Hospital Intensive Care Unit. 23 ICU patients with Acute Renal Failure needing CVVHDF were studied during standard CVVHDF therapy, at random infusion in the extracorporeal circuit of PGIA or UFH.
