The Effects of Preoperative Administration of Erythropoietin in Pediatric Patients Undergoing Cranial Vault Remodeling for Craniosynostosis.

Abstract

BACKGROUND AND PURPOSE:

Over 90% of patients undergoing cranial vault remodeling for craniosynostosis receive blood transfusions to compensate for intraoperative blood loss. However, transfusions are not without risk and can lead to allergic and immune transfusion reactions as well as rare cases of infectious transmissions. Preoperative use of erythropoietin in cranial vault remodeling has been demonstrated to be safe and to reduce transfusion requirements in prior studies. This study's purpose is to add to the body of data supporting the safe use of a protocolized erythropoietin alfa regimen before cranial vault remodeling and strip craniectomy procedures with decreased blood transfusion requirements and other favorable outcomes.

METHODS:

A retrospective chart review was performed on patients who underwent cranial vault remodeling between 2006 and 2021 at our tertiary care center. Two groups were identified: in the first, preoperative erythropoietin was administered under protocol; and in the second, preoperative erythropoietin was not administered. The groups were compared with respect to age, perioperative hemoglobin levels, estimated blood loss during surgery, packed red blood cell transfusion volume, length of hospital stay, and length of surgery.

RESULTS:

Demographics were not significantly different in terms of age, weight, diagnosis, gender, and type of procedure. Patients who were administered preoperative erythropoietin were found to have significantly increased preoperative hemoglobin levels (13.6 versus 12.3 g/dL), as well as decreased estimated intraoperative blood loss (376 versus 1099 mL), the volume of packed red blood cells transfused (316 versus 897 mL), length of hospital stay, and length of surgery. Postoperative hemoglobin levels were not found to be significantly different.

CONCLUSIONS:

In this study, preoperative administration of erythropoietin with elemental iron was beneficial for patients undergoing cranial vault remodeling for craniosynostosis. Specifically, it decreased the need for red blood cell transfusion, intraoperative blood loss, and length of hospital stay. No adverse events were recorded in the treatment arm. Further studies may include a separate group administered iron alone.
