[Cryopreservation of erythrocytes with hydroxyethyl starch. In vitro results leading to an autologous retransfusion model in the dog].
Although the effectiveness of hydroxyethyl starch (HES) as a cryoprotectant for human red blood cells (HRBC) is well known, no clinical application has evolved so far. In contrast to glycerol HES has the advantage of causing no hemolysis per se. This offers the opportunity of a one-step procedure without a time consuming postthaw washing procedure prior to transfusion. ⋯ Postthaw survival in terms of saline stability differed markedly (67 +/- 6 and 86 +/- 2%, respectively). DRBC were more susceptible to hypotonic stress than HRBC. Nevertheless, after cryopreservation 91% (HRBC) and 92% (DRBC) of the original 2,3-DPG were found in the thawed RBC concentrates.

[Transfusion commission and service recommendations for increasing efficiency in transfusion medicine].
Establishing a University Hospital Transfusion Committee has improved the communication between all the hospitals and enhanced the aspects of security and efficiency in transfusion medicine. Moreover, the field of transfusion medicine has gained more recognition through the university hospital management.

[Development and results of autologous blood transfusion in Magdeburg].
The autologous blood transfusion is an important part of the modern hemotherapy. Especially in orthopedics presurgical blood donation of the patients is possible since the operations are exactly planable close. Cooperation between the clinic and the transfusion service is necessary. The results of autologous transfusions in 1,086 patients (1,428 donations) of an orthopedic clinic over a period of six years were critically analyzed.
