Background: A retrospective study was performed to evaluate whether pretreatment with erythropoietin and iron combined with acute preoperative normovolaemic haemodilution (APNH) could decrease homologous blood transfusion in craniosynostosis (CS) surgery. A treated group was compared with a historical group of infants who underwent surgery with no pretreatment.
Methods: The charts of 25 healthy infants who underwent CS surgery were reviewed. Nine of them underwent surgery with no treatment beforehand. Sixteen infants were given erythropoietin at a dosage of 300 U.kg -1 two times per week and iron (elemental iron 10 mg.kg-1.day-1) for 3 weeks before surgery. On the day of surgery APNH was performed after induction of general anaesthesia; a precalculated amount of autologous blood was withdrawn and replaced by hydroxyethyl starch 6%.
Results: Eleven of the 16 infants of the study group received only autologous blood. Five of 16 received homologous blood transfusion vs seven of nine infants in the control group.
Conclusions: APNH combined with erythropoietin was effective in reducing homologous blood requirements during CS surgery. Further studies are necessary on a larger scale to assess the role of this technique in avoiding homologous blood transfusion and to evaluate how infants can benefit from this combined approach.
