Autologe Transfusion bei Skolioseoperationen: Präoperative Eigenblutspende und intraoperative maschinelle Autotransfusion [Autologous transfusion in scoliosis operations: preoperative autologous blood donations and intraoperative mechanical autotransfusion]

Abstract

Autologous transfusion was used to reduce the high demand for blood accompanied with scoliosis surgery. Half of the blood loss could be saved by intraoperative autotransfusion (35 patients). This resulted in a corresponding reduction in homologous transfusion. An elimination of the need for homologous blood could be achieved only by the combination of preoperative blood donation and intraoperative autotransfusion (37 patients). With freezing the predeposit blood was independent of storage time and autologous plasma was available. Thus, the risks of transfusion can be avoided.
