RESUMO
OBJECTIVES: To assess the usefulness of tranexamic acid (TA) in pediatric cranial remodeling surgery, by analyzing its effects on bleeding and transfusion requirements, number of days of cranial drainage required, and time spent in the postoperative recovery unit. MATERIAL AND METHOD: A single-blind, controlled study was designed with 20 patients (10 cases and 10 controls) randomly assigned to receive or not receive 15 mg/kg of intravenous TA upon anesthetic induction, every 4 hours during surgery, and every 8 hours throughout the 48 hours after surgery. Variables analyzed were results of blood tests, blood loss, volume transfused, time in the recovery unit, and complications related to TA infusion. RESULTS: The group treated with TA experienced less bleeding during surgery than did the controls (199 +/- 60 vs 290 +/- 43 mL) and had less need of intraoperative (176 +/- 104 vs 206 +/- 70 mL) and postoperative transfusion (9 +/- 28 vs 52 +/- 72 mL) 24 hours after surgery. TA group patients also spent less time in the recovery unit (60 +/- 14 vs 72 +/- 11 hours). Blood test variables in TA-treated children were also better 24 hours after surgery with regard to hemoglobin (12.1 +/- 2 vs 11.6 +/- 1.3 mg/dL) and platelet (261 +/- 68.5 vs 181.6 +/- 58.1 platelets/mm3) concentrations, and cephalin time (33 +/- 12 vs 49 +/- 16 seconds). No complications related to TA treatment were observed. CONCLUSIONS: TA can reduce perioperative bleeding in the context of pediatric cranial remodeling surgery. TA-treated patients have less need of transfusion and this may reduce the rate of related complications as well a make care more efficient.
