[The use of erythrocyte concentrates, preserved at low temperature, in hematologic patients].

The transfusion protocols of 70 patients with haematological diseases were evaluated and compared. 68 patients of them received frozen erythrocyte concentrates stored at low temperatures (TTK-EK). A total of 1,183 courses of transfusion with 2,744 transfusion units (TE) were examined for erythrocyte substitution. 841 normal erythrocyte concentrates (n. EK), 905 washed erythrocyte concentrates (gew. EK), and 998 frozen erythrocyte concentrates were transfused. With 0.5% the rate of side-effects after frozen erythrocyte concentrates lay significantly lower than after other suspensions. Indications and advantages of TTK-EK are discussed. The application of double units is further recommended.
