[Supportive hemotherapy in anemias].

The substitution of blood and erythrocytes, respectively, has to be performed as an aimed supportive haemotherapy according to measure. Therefore full blood is indicated only in loss, otherwise only concentrates of erythrocytes may be transfused, in order to exclude side-effects as a potential danger. The latter should above all produced buffy-coat-free. Washed preparations of erythrocytes should be used only in such a case, when there are present clear clinical demands, such as transfusion reactions which can otherwise not be removed, and which for their part limit the success of the transfusion. The practically plasma-free concentrates of erythrocytes which are extremely poor in alloantigens and preserved at deep temperature should at present be used for reasons of capacity only in persons who are potentially to be transfused many times, above all in recipients of grafts.
