Tranexamic Acid for the Reduction of Allogeneic Blood Exposure in Infants and Children Having Craniofacial Surgery

Surgical procedures for the correction of craniofacial deformities result in unavoidable and significant blood loss in small children and infants. Patients may experience blood losses that exceed one to two blood volumes. In an effort to reduce our transfusion requirements, we have introduced tranexamic acid into our practice. However, the benefit of tranexamic acid in pediatric craniofacial surgery has not yet been reported. We hypothesize that the intraoperative use of tranexamic acid in pediatric patients presenting for craniofacial reconstructions will reduce blood loss and allogeneic transfusion requirements.

This is a randomized, blinded, prospective study that will investigate the potential benefit of tranexamic acid to reduce the intraoperative bleeding and blood transfusions in pediatric patients undergoing craniofacial surgeries. An initial dose of 100 mg/kg tranexamic acid (Cyclokapron 100mg/ml) or an equal volume of a placebo will be administered over 15 minutes after the induction of anesthesia and before the skin incision. A maintenance infusion of 10 mg/kg/hr of tranexamic acid or equal volume of a placebo will be started upon completion of the initial dose and will be continued until skin closure. The primary outcome will include the reduction in the total volume of allogeneic erythrocytes.
