| Abstract: | In healthy volunteers, 500 ml of a 6% low molecular weight hydroxyethyl starch solution (Expafusin) was infused intravenously within 30 minutes. Blood samples for the measurement of rheological parameters were obtained before and after the infusion. Blood and plasma viscosity were significantly decreased after the infusion of HES. Red cell deformability as measured by a filtration technique was slightly improved. Red cell aggregation as measured by a light transmission method was markedly reduced. Repeated infusion of 500 ml Expafusin indicates that the improvement of the flow properties of blood can be maintained for more than 3 hours. |
