Surgery for craniosynostosis is associated with the potential for significant blood loss. Multiple technologies have been introduced to reduce the volume of blood transfused. These are preoperative autologous donation; preoperative erythropoietin; intraoperative cell salvage (CS); acute normovolemic hemodilution; antifibrinolytic drugs such as tranexamic acid, ε-aminocaproic acid, and aprotinin; fibrin sealants or fibrin glue; and postoperative drain reinfusion. ⋯ The production of high-quality evidence on the interventions to minimize blood loss and transfusion in children undergoing surgery for craniosynostosis is difficult. Most of the literature is nonrandomized and noncomparative. Several areas remain unaddressed. Erythropoietin and tranexamic acid are comparatively well studied; CS, acute normovolemic hemodilution, and aprotinin are less so. There is only 1 comparative study on the use of fibrin glue and drain reinfusion, with no studies on preoperative autologous donation and [Latin Small Letter Open E]-aminocaproic acid. Tranexamic acid is clinically effective in reducing allogeneic blood transfusion. There is some evidence that CS and erythropoietin may be clinically effective. None of the interventions studied are shown to be cost-effective because of lack of evidence.
