Eligibility
Key inclusion criteria
1.The treating clinician believes that the patient requires CRRT for acute renal failure. 2. The clinician is uncertain about the balance of benefits and risks likely to be conferred by treatment with higher intensity or lower intensity CRRT. 3. The patient fulfils one of the following clinical criteria for initiating CRRT: Oliguria (urine output < 100ml/6hr) that has been unresponsive to fluid resuscitation measures. Hyperkalemia ([K+] > 6.5 mmol/liter). Severe acidemia (pH < 7.2). Urea > 25mmol/liter. Clinically significant organ oedema (eg: lung). Creatinine >300mmol/liter 4. The treating clinicians anticipate treating the patient with CRRT for at least 72 hours.

Key exclusion criteria
1. Patient age is <18 years. 2. Death is imminent (<24 hours). 3. There is a strong likelihood that the study treatment would not be continued in accordance with the study protocol. 4. The patient has been treated with CRRT or other dialysis previously during the same hospital admission. 5. The patient was on maintenance dialysis prior to the current hospitalization. 6. The patients body weight is <60kg or >100kg. 7. Any other major illness that, in the investigators judgment, will substantially increase the risk associated with the subjects participation in this study.
