The efficacy of predeposited autologous blood transfusions in general pediatric surgery

Allogeneic blood transfusions are associated with a risk of infection, immunological reactions, immunosuppression, and the induction of antibodies in blood cells. We report our results of giving predeposited autologous blood transfusions (PABT) to children when it was anticipated that transfusions would be required for an elective operation. Autologous blood was collected for deposit from 16 patients ranging in age from 1 to 11 years old (mean 5.6 years old, mode 4 years old), and weighing from 9.7 to 42 kg (mean 20.8kg). They included 12 patients with pectus excavatum (funnel chest) and 4 patients with choledochal cyst (CBD). Blood was collected once from 2 patients and twice from the other 14 patients, then centrifuged and stored in a freezer at -80 degrees C. Between 7 and 14 ml/kg was collected at one time, the total mean volume of predeposited blood being 21.0 +/- 3.3 ml/kg for the children operated on for funnel chest, and 16.2 +/- 4.5 ml/ kg for those operated on for CBD. None of the patients required allogeneic transfusions and no complications occurred. PABT was found to be a safe and effective means for elective general pediatric surgical procedures for avoidance of allogeneic blood transfusion.
