Current Primary Outcome Measures  ICMJE
 (submitted: August 11, 2010)
Change in dialyzer blood compartment volume when the heparin dose is adjusted using a Robbins-Monro algorithm [ Time Frame: up to 8 weeks ]
The objective is to titrate each patient's heparin dose to the level that achieves adequate anticoagulation for that patient as assessed by the change in blood compartment volume of the dialyzer from pre- to post-dialysis. The strategy that will be used is the Robbins-Monro stochastic approximation algorithm.

Descriptive Information
Brief Title  ICMJE A Pilot Study of a Heparin Dosing Algorithm for Hemodialysis
Official Title  ICMJE Heparin Dose Reduction During Hemodialysis With the Gambro Revaclear and Revaclear MAX Hemodialyzers: Pilot Study I and II
Brief Summary During hemodialysis treatments, patients receive heparin to prevent clotting. The purpose of this pilot study is to determine if the amount of heparin administered during a patient's hemodialysis can be individualized using an equation for heparin dose adjustment.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Renal Failure Chronic Requiring Hemodialysis
Intervention  ICMJE Procedure: Heparin dose titration
Patients will begin the study using their currently prescribed heparin doses - both bolus and constant infusion - for three treatments to establish a baseline and provide information on inter-treatment variability in dialyzer clotting. Subsequently, the bolus and infusion rates will be titrated either upward or downward based on the Robbins-Monro process and an evaluation of dialyzer clotting during the preceding treatment. Heparin doses will be adjusted for a total of 30 dialyses.
Study Arms  ICMJE Experimental: Heparin dose titration
Intervention: Procedure: Heparin dose titration
