Biofiltration: an effective and simple method to reduce dialysis time.
Biofiltration: an effective and simple method to reduce dialysis time. Six stable anuric patients, on maintenance hemodialysis, were treated for 10 weeks with a parallel flow 1 m2 cuprophan filter, for 20 weeks with a parallel flow 1.2 m2 polyacrylonitrile filter using the biofiltration (BF) technique and again 10 weeks with the cuprophan filter. Usual monitors were used, without automatic control of ultrafiltration. Biochemical and hematological profile, urea kinetic parameters, incidence of hypotensive episodes, body weight and blood pressure did not change throughout the study. We conclude that three hours of BF, at least for 20 weeks, are as effective and well tolerated as four hours standard hemodialysis and could be of value in reducing dialysis time, to permit better utilization of dialysis beds.
