Scientific title
A randomised phase I study to evaluate the effects of different pre-dilution volumes associated with Continuous Veno-Venous Haemofiltration (CVVH) and Continuous Veno-Venous Haemodiafiltration (CVVHDF) to improve the efficacy of CRRT (Continuous Renal Replacement Therapy) in the treatment of severe Acute Renal Failure (ARF) by the extension of circuit life.

Description of intervention(s) / exposure
Continuous Renal Replacement Therapy (CRRT) is an established treatment option in Australia for critically ill patients with severe Acute Renal Failure (ARF). Treatment efficiacy of CRRT is dependent on the continuous nature of the therapy to achieve azotemic control, normalisation of serum sodium, potassium and bicarbonate concentrations, and in the management of fluid volume. Due to the development of blood clots in the extracorporeal circuit the continuous nature of CRRT is interrupted. The aim of this research project is to evaluate the discontinuation of circuit life due to clotting between two widely used forms of CRRT. The impact of Continuous Veno-Venous Haemofiltration (CVVH) and Continuous Veno-Venous Haemodiafiltration (CVVHDF) will be investigated using a randomised crossover study design. Patients participating in the study will be intially randomised to receive either CVVH or CVVHDF and crossover to the other treatmenet modality only when each circuit has run its natural course. Provided the change of modality occurs sequentially and both circuits are taken down due to clotting, only one crossover between the two treatment modalities will be necessary. The patient will then resume CVVHDF in accordance with standard unit practice until CRRT is no longer required.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A series of sealed envelopes corresponding to the patient's enrolement number will contain a specific treatment order.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be achieved using a computer generated sequence of random numbers to determine which mode is to be assigned to the patient prior to commencement of treatment.
Masking / blinding
