[The rheologic aspects of washed donor erythrocytes]

Washing off donors' red blood cell pack with NaCl isotonic solution results in improvement of red blood cell rheologic properties: their aggregation reduces, deformability increases, osmotic resistance rises. Heparin addition to the washing off solution in a dose of 5 IU/ml prevents development of antiheparin activity in red blood cells after washing off. Application of washed-off red blood cells of donors has advantages as compared to transfusion of the whole blood.
