Hemorheology in biofiltration and acetate dialysis (preliminary results).

ABSTRACT

Hemorheological measurements were made in 8 stable chronic haemodialysis patients observed in conventional acetate dialysis (AD) with Cuprophan membrane and then in biofiltration (BF) with PAN AN69S membrane. Blood viscosity diminished at the beginning, both during BF and AD, reaching pre-dialytic values again at the end of treatment. Blood and erythrocyte filtration increased after 20 min in AD and throughout the session in BF. Preliminary results suggest an improvement of hemorheological parameters during dialytic treatment, more notable in BF than in AD.
