Abstract

Background: Cranial vault remodeling (CVR) for craniosynostosis is a procedure with the potential for significant blood loss. Aminocaproic acid (ACA) has been used at our institution during CVR for its antifibrinolytic effects. The purpose of this study was to investigate the effect of ACA on blood loss and transfusion rates during primary CVR. Methods: Three hundred eighty-three patients with craniosynostosis underwent primary CVR at a single institution by a single surgeon over 15 years. Patients were included if they received either ACA or no antifibrinolytic. The estimated blood loss (EBL) and volume of blood transfused was recorded. Thrombotic-related complications were identified. Comparisons were made between subgroups using independent Student t test and Fisher exact test. Results: Among the study population, 148 patients met inclusion criteria. ACA was given to 30 patients, while 118 patients received no antifibrinolytic. There was no difference in the average intraoperative EBL between the ACA (322 mL) and control groups (327 mL, P > 0.05). Additionally, the incidence of transfusion was not significantly different between subgroups (97% vs. 86%, respectively, P > 0.05). Patients treated with ACA, however, received lower average perioperative transfusion volumes (25.5 mL/kg) compared to control patients (53.3 mL/kg, P < 0.0001). Furthermore, patients in the ACA subgroup were less likely to require a second unit of blood (21% vs. 43%, P < 0.0001) and therefore had fewer exposures to donor blood antigens (ARR = 22%, NNT = 4.6). Conclusions: The use of intraoperative ACA minimizes blood transfusion volumes and donor exposures in children who undergo primary CVR for craniosynostosis. Antifibrinolytics should be considered for routine use in pediatric craniofacial surgery.
