Perioperative Blood Loss and Transfusion in Craniosynostosis Surgery

Area of Science:

• Pediatric Surgery
• Craniofacial Surgery
• Anesthesiology

Background:

• Craniosynostosis affects 1 in 2000-2500 live births, necessitating surgical correction.
• Surgical correction of craniosynostosis involves substantial blood loss (20%-500% of total circulating volume).
• High blood loss poses risks of transfusion-related adverse events.

Purpose of the Study:

• To analyze perioperative blood loss and transfusion rates in pediatric patients undergoing craniosynostosis surgery.
• To identify factors associated with significant blood loss and transfusion requirements.

Main Methods:

• Retrospective analysis of 40 pediatric patients with craniosynostosis (>16 years) at a single tertiary craniofacial center.
• Data collected included pre-, intra-, and postoperative hemoglobin, hematocrit, and tranexamic acid use.
• Calculated estimated percentage of circulating red cell volume lost and transfused.

Main Results:

• Average estimated red cell volume loss was 77% of circulating volume.
• 90% of patients received blood transfusions, averaging 88.3% of circulating red cell volume.
• Longer operative time, younger age, and lower weight were associated with >50% blood volume transfusion (P < 0.05).

Conclusions:

• Red cell volume loss in craniosynostosis surgery is significant and comparable to existing literature.
• Younger age, lower weight, and longer operative times are key predictors of substantial transfusion needs.
• These findings highlight the importance of managing blood loss in pediatric craniofacial surgery.
