Continuous haemofiltration maintains fluid balance and reduces haemodialysis requirement in acute renal failure

We have used continuous arteriovenous haemofiltration with Amicon 20S Diafilters in combination with conventional haemodialysis as routine management for acute oliguric renal failure in fifteen patients. Haemofiltration provided a variable fluid output of up to eight litres daily, enabling unrestricted nutrition and reduced frequency of haemodialysis.
