Intra- and postoperative autotransfusion in open heart surgery under simple hypothermia in children

A new autotransfusion unit was developed by the authors and the favorable results of 21 operations of open heart surgery under simple hypothermia were described. The patients were all children with simple congenital heart diseases. The amounts of autotransfused blood ranged from 2.8 to 15.5 ml/kg. Intraoperative autotransfusion proved to be an effective means of minimizing blood loss during surgery (range 3.2 to 12.8 ml/kg) and performing open heart surgery without donor blood transfusion. Postoperative autotransfusion (range 0 to 14.3 ml/kg) served as a supplementary means of avoiding homologous blood transfusion. Among the 21 autotransfused patients, there were no complications, while two patients developed hepatitis out of 19 patients who received homologous blood in the control group.
