Active Comparator: Dilute heparin
Arm A will receive dilute heparin delivered as an intravenous infusion proximal to the dialysis filter.
Drug: Dilute unfractionated heparin
Patients in the dilute heparin arm will receive a systemic loading dose of heparin of 15 units per kilogram of weight by rapid intravenous bolus. Then a maintenance rate of heparin of 7.5 U/Kg per hour will be started. Heparin will be delivered as a solution of 2 units/mL and the infusion will be prepared with 2,000 units of heparin in 1,000 mL of 0.9% NaCl and delivered intravenously proximal to the dialysis filter.
Other Name: Heparin
Active Comparator: Standard concentrated heparin
Arm B will receive standard concentrated heparin and will be delivered as an intravenous infusion proximal to the dialysis filter.
Drug: Standard concentration unfractionated heparin
Patients in the standard heparin arm will receive a systemic loading dose of heparin of 15 units per kilogram of weight by rapid intravenous bolus. Then a maintenance rate of heparin of 7.5 U/Kg per hour will be started and delivered in a standard concentration intravenously proximal to the dialysis filter via a syringe. The concentration of heparin used will be 1,000 units of heparin per 1 mL of 0.9% NaCl.
Other Name: Heparin
- Filter life [ Time Frame: 72 hours ]The primary endpoint for this study will be the difference in filter life in hours between the group receiving dilute heparin and the group receiving standard concentrated heparin.
- Bleeding complications [ Time Frame: 72 hours ]Information on minor bleeding complications, major bleeding complications, and need for blood product transfusions will be collected.
