[The place of autotransfusion with normovolaemic haemodilution in vascular surgery (author's transl)]. 1979

B Urbanyi, and G Spillner, and W Buzello, and V Schlosser

The ever-increasing demand for donor blood, the risks of donor-blood transfusions and economic considerations have made the use of autotransfusion desirable. Among methods for producing autologous blood stores that of obtaining autologous blood with simultaneous normovolaemic haemodilution (using dextran 60; Macrodex 6%) 2--4 days before operation is especially practicable for elective reconstructive vascular surgery. But the same method can also be used in general surgery. Personal experience in operations on 120 patients has shown that the need for donor blood was reduced to 20% of all transfused blood. Improved flow properties of the blood by decreasing viscocity after normovolaemic haemodilution is of particular value in stages III and IV of chronic arterial occlusive disease.

D011300 Preoperative Care Care given during the period prior to undergoing surgery when psychological and physical preparations are made according to the special needs of the individual patient.

D001809 Blood Viscosity The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.

D006438 Hemodilution Reduction of blood viscosity usually by the addition of cell free solutions. Used clinically (1) in states of impaired microcirculation, (2) for replacement of intraoperative blood loss without homologous blood transfusion, and (3) in cardiopulmonary bypass and hypothermia.
