胸腰椎外科手術における自己血輸血

抄録

Autotransfusion avoids the risk of disease transmission, isoimmunization, and the graft-versus-host disease that is seen with an homologous blood transfusion.
In our hospital, thoraco-lumbar surgery, which is expected to have much blood loss, has been performed with venesection and an intraoperative autotransfusion method by Cell Saver 4 since 1989.
Venesection was performed 2.12 times on an average for each case and the volume was 785g. The average ratio of intraoperative autotransfusion to total blood loss was 37.9%.
Only one of the 5 cases which bled more than 3000g of total blood loss did not necessitate any homologous blood, but the other 4 cases did.
With our method of autotransfusion, the limitation of total blood loss is suspected to be about 3000g.
