Blood loss during repair of craniosynostosis
1Department of Paediatric Anaesthesiology, Hôpital des Enfants-Malades, Paris, France.
Insights
Craniosynostosis surgery risks can be managed with intraoperative hemodilution. This technique helps control blood loss and transfusion needs, reducing risks associated with blood transfusions in pediatric patients.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Hematology
Background:
- Craniosynostosis repair is associated with significant blood loss and transfusion risks.
- Managing perioperative blood loss is crucial for patient safety.
Purpose of the Study:
- To evaluate the efficacy of intraoperative hemodilution in managing blood loss during craniosynostosis repair.
- To assess the accuracy of blood loss estimation and transfusion requirements using packed cell volume (PCV) measurements.
Main Methods:
- A cohort of 115 patients undergoing craniosynostosis repair were managed using intraoperative hemodilution.
- Target final packed cell volume (PCV) was maintained between 0.28-0.35.
- Blood loss and transfusion volumes were calculated using red blood cell mass estimations based on PCV.
Main Results:
- Estimated red cell volume lost was 91% +/- 66% of the patient's total red cell volume.
- Perioperative transfusion was satisfactory in 48% of patients, with 32% experiencing slight overtransfusion.
- Postoperative liberal blood administration resulted in overtransfusion in 74% of patients.
Conclusions:
- Intraoperative hemodilution is a viable strategy to manage blood loss in craniosynostosis surgery.
- Strict volume compensation and hemodilution techniques are recommended to minimize transfusion risks, including infectious disease transmission.
- Optimizing transfusion protocols is necessary to avoid unnecessary transfusions in the postoperative period.
Abstract:
Surgical repair of craniosynostosis carries a high risk with large blood losses. Over a 2-yr period, we have managed 115 patients undergoing craniosynostosis repair with peroperative haemodilution to achieve a final PCV of 0.28-0.35. Measurements of PCV allowed calculation of estimated blood losses and transfused volumes in terms of red blood cell mass. Total estimated red cell volume lost was 91 +/- 66% of patient's estimated red blood cell volume during the peroperative period. The type of skull deformation and surgical procedure determined the extent of peroperative bleeding. Peroperative transfusion was satisfactory in 48% of patients and slight overtransfusion was noted in 32%. During the postoperative period, liberal administration of blood led to overtransfusion and possibly unnecessary transfusion in 74% of patients. Because of the well known risks of transmission of infectious disease, strict volume compensation with development of haemodilution and autotransfusion procedures should be used to limit these risks.
