Reducing Postoperative Bleeding After Craniosynostosis Repair Utilizing a Low-Dose Transexamic Acid Infusion Protocol.

Background: Craniosynostosis surgery is associated with large volume blood loss and the need for blood transfusion. Recently, the use of tranexamic acid (TXA) has been demonstrated to be helpful in reducing perioperative blood loss in many pediatric procedures. This study used a low-dose pharmacokinetic TXA dosing protocol and assessed its ability to limit perioperative blood loss for craniosynostosis repairs. Methods: A retrospective chart review was conducted of pediatric craniosynostosis surgeries performed at our institution between September 2011 and December 2014. Outcome measures included comparisons of perioperative blood loss and transfusion rates in patients who had surgery with or without TXA. Results: Twenty-five patients met inclusion criteria. Nine patients had craniosynostosis surgery without TXA (no-TXA group) and 16 patients received TXA (TXA group). The TXA group had significantly higher postoperative hemoglobin levels than the no-TXA group (P = 0.009). This finding was supported by significantly higher postoperative estimated red cell volume in the TXA group (P = 0.017). Postoperative 24-hour drain output was significantly lower in the TXA group (P = 0.042). The volume of packed red blood cells transfused perioperatively was not significantly different between groups. Conclusions: Patients who received TXA during craniosynostosis surgery at our institution had higher postoperative hemoglobin levels and lower 24-hour drain output. However, TXA was not associated with lower perioperative blood transfusion rates. (C) 2017 by Mutaz B. Habal, MD.
