[Hemorheological changes induced by uremia. Effects of hemodialysis]

Fifteen patients affected by chronic uremia and treated with hemodialysis were studied. The main hemorheological parameters were evaluated in basal conditions and after hemodialytic therapy and were correlated with some hematochemical indices. Although some limitations to the purpose of this study derive from the heparinization of the blood during hemodialysis, the results of this study demonstrate that erythrocyte filtration does not significantly change during the hemodialytic therapy. The only hemorheological parameter altered in the uremic patient is represented by plasma viscosity; this is probably due to the increase of fibrinogenemia in these patients.
