Abstract

Abstract : Supplemental Digital Content is available in the text Abstract : Background: Blood loss and subsequent transfusion are key concerns in the surgical management of craniosynostosis, and have been associated with increased morbidity, requirement for intensive care admission and increased length of hospital stay. Patient blood management guidelines advocate treatment of anemia before elective surgical procedures where significant blood loss is anticipated. At present there is little evidence in the literature investigating the clinical value of this practice in pediatric craniofacial surgery. Aims: The authors examined the effect of preoperative oral iron supplementation on blood loss and transfusion rates in a national pediatric craniofacial unit. Methods: A total of 157 patients were included in a retrospective and prospective observational cohort study conducted between July 2011 and November 2016. Eighty-five (85) patients included in the preoperative iron supplementation group were prescribed oral ferrous fumarate before total cranial vault reconstruction, frontal-orbital advancement or extended strip cranial vault remodeling procedures. This cohort was retrospectively compared to seventy-two (72) consecutive patients who did not receive iron supplementation. Results: Calculated blood loss was 51.3 mL/kg in the intervention group, and 56.65 mL/kg in the control group. Transfusion rate and mean volumes for the intervention group were 85.9% and 25 mL/kg. The control group had transfusion rate of 86.1% with mean transfused volume of 24.7 mL/kg. These differences were not statistically significant. Intraoperative tranexamic acid was associated with significantly reduced transfusion volumes overall. Conclusions: This study did not show a statistically significant benefit to preoperative iron supplementation. Secondary outcomes of this study showed a statistically significant difference in estimated versus calculated intraoperative blood loss. Further research in to specific iron supplementation protocols is indicated.
