Blood transfusions are necessary in scoliosis surgery in many cases. But they are not innocuous because they introduce the risk of serum hepatitis and various immune reactions. Autotransfusions can minimize this risk. In our hospital, scoliosis surgery was performed in 13 children participating in an autotransfusion program from 1981. Preoperatively, collection volume was 25-30g/kg weight blood early but recently 40-45g/kg is collected. There are no complication apart from transient dizziness. It is able to draw as much blood as 40g/kg/3wks. Bleeding volume was 200g per vertebral body in anterior procedure and 150g per vertebral body in posterior procedure. So we consider that the upper limit of a number of fused bodies is 10 in posterior procedure and 7 or 8 in anterior procedure. The results of this study show that autotrasfusions are a satisfactory method in elective scoliosis surgery.
