[Open heart surgery without the use of homologous blood in infants and young children: effectiveness of the intraoperative autologous blood donation from arterial monitoring line].

Open heart surgery without the use of homologous blood transfusion was attempted in 81 pediatric patients weighing 5.5-14.9 kg. Autologous blood was donated from arterial monitoring line after induction of anesthesia. This donated blood, actual volume of 9.2 +/- 1.7 ml/kg, was reinfused following the cessation of extracorporeal circulation. Hemodilution resulting from autologous blood donation was well tolerated by all patients. Sixty-eight patients (84%) were operated on successfully without the need for homologous blood. These data suggest that autologous blood donation from arterial monitoring line is a safe and effective method to avoid homologous blood transfusion especially in infants and young children undergoing open heart surgery.
