CD contains a small amount of citric acid rather than acetic acid as the acidifying agent. The use of citrasate may lead to lower heparin requirements in hemodialysis.

There is a four week run in phase followed by two weeks of intervention AD or CD followed by the remaining AD or CD intervention.\n\nThe primary outcome is change in intradialytic heparin dose achieved with citrasate compared with acetate dialysate. Secondary outcomes are the effect of CD compared with AD on systemic anticoagulation, bleeding time after HD, metabolic parameters, dialysis adequacy, inflammation, hemodynamic stability, and intra-rater and inter-rater reliability of the dialyzer clotting score.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* chronic stable HD patients ≥ 18 years\n* on HD at least three times per week for at least 3 months\n\nExclusion Criteria:\n\n* contraindication to heparin\n* currently using heparin-free HD\n* known clotting disorder\n* on warfarin therapy\n* dialyzing with a dysfunctional central venous catheter (blood flow rates consistently less than 300mL/min and/or frequent use of thrombolytic)\n* history of vascular access dysfunction\n* planned vascular access conversion or procedure during the study period\n* use of high calcium dialysate\n* active medical issue requiring hospitalization\n* planned kidney transplant during the study period\n* planned conversion of dialysis modality (peritoneal dialysis, nocturnal dialysis) during the study period\n* unable to provide informed consent'}, 'identificationModule': {'nctId': 'NCT01466959', 'briefTitle': 'The Effect of Citrasate Dialysate on Heparin Dose in Hemodialysis', 'organization': {'class': 'OTHER', 'fullName': 'University of Calgary'}, 'officialTitle': 'The Effect of Citrasate Dialysate on Heparin Dose: A Randomized Cross Over Trial in Hemodialysis Patients.', 'orgStudyIdInfo': {'id': 'ID24009'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'AD- acetic acid dialysate', 'description': 'AD is a standard bicarbonate based dialysate with a small amount of acetic acid which is the standard of care for dialysis.', 'interventionNames': ['Other: acetic-acid based dialysate (AD)']}, {'type': 'EXPERIMENTAL', 'label': 'CD - citrasate dialysate', 'description': 'Dialysis with a citric acid based dialyasate.', 'interventionNames': ['Other: citrate dialysate (CD)']}], 'interventions': [{'name': 'citrate dialysate (CD)', 'type': 'OTHER', 'otherNames': ['Citrasate', 'Citric acid dialysate'], 'description': 'Citrasate (CD) is substituted as the dialysate during the patients regular dialysis run 4hours three times weekly for a period of 2 weeks.
