Preoperative autologous blood donation for cardiac surgery in children

Area of Science:

• Pediatric Cardiac Surgery
• Transfusion Medicine
• Autologous Blood Donation

Background:

• Homologous blood transfusion is common in pediatric cardiac surgery.
• Limited data exists on autologous blood donation in young children.
• Preoperative autologous blood donation (PABD) may reduce allogeneic blood use.

Purpose of the Study:

• To evaluate the safety and efficacy of PABD in children undergoing cardiac surgery.
• To assess the impact of PABD on homologous blood transfusion rates in pediatric patients.

Main Methods:

• A prospective study of 50 children (6 months to 5 years) undergoing primary cardiac surgery.
• 23 children donated autologous blood (10 mL/kg twice) preoperatively.
• 27 age and weight-matched controls received standard care.

Main Results:

• No complications were observed during autologous blood collection.
• Homologous blood use was significantly lower in the autologous group (4.3%) vs. control (44.4%).
• Hemoglobin levels remained comparable across both groups throughout the study period.

Conclusions:

• PABD is safe and effective in reducing homologous blood transfusions in pediatric cardiac surgery.
• The benefits of PABD extend to children weighing less than 15 kg.
• PABD is a viable strategy for optimizing blood management in pediatric cardiac procedures.
