The influence of hyper- and isovolaemic hemodilution using HES 200/0.5 6% (HES steril, Fresenius AG) on pain-free walking distance in patients with peripheral arterial occlusive disease stage II according to Fontaine was tested in a randomised investigation involving three groups. The increase in pain-free walking distance was significant both in the hypervolaemic and isovolaemic hemodilution group. The increase in both dilution groups did not differ but compared to a control group (infusion of Ringer lactate) it was significantly higher. Considerable changes concerning rheological parameters (decrease in haematocrit and plasma viscosity) were observed after isovolaemic hemodilution.
