Abstract
Surgical correction of craniosynostosis in children is associated with substantial intraoperative bleeding. Intraoperatively administered tranexamic acid (TXA) can lessen blood loss during orthopedic and cardiovascular surgery, but its efficacy in craniosynostosis surgery is uncertain. Therefore, a meta-analysis performed with published comparative studies was to determine whether TXA could reduce packed red blood cells (or erythrocytes) (PRBCs) transfused and blood loss during pediatric craniosynostosis surgery. Two PubMed and EMBASE electronic databases were searched until June 2012. Eligible studies were restricted in comparative controlled trials. Four studies in 3 articles with 138 patients were included. The results showed that intraoperative administration of TXA can significantly reduce transfusion of PRBCs (weighed mean difference [WMD] = -10.81, 95% confidence interval [CI] = -16.84 to -4.78, P < 0.00001). In the level of blood loss, the meta-analysis on 4 studies showed that the difference was statistically significant (WMD = -20.53, 95% CI = -32.26 to -8.80, P = 0.0006) between the TXA groups and the control groups. However, the subgroup analysis on randomized controlled trials showed that TXA did not significantly reduce blood loss during surgery compared with the placebo group (WMD = -30.79, 95% CIs = -71.72 to 10.14, P = 0.14). Tranexamic acid can significantly reduce the transfusion of PRBCs in children undergoing craniosynostosis surgery. However, there is a controversy on the efficacy of TXA in reducing blood loss. Therefore, new randomized controlled trials to assess the effects of TXA in children with craniosynostosis surgery should be conducted.
