Performance of functional fibrinogen thromboelastography in children undergoing congenital heart surgery.

In pediatric patients undergoing cardiac surgery, FLEV derived from Functional Fibrinogen correlated linearly with plasma fibrinogen levels (Clauss) both before and after CPB. FLEV estimation of plasma fibrinogen was improved after CPB in neonates, infants, and small children. After CPB, FFTEG can be used to predict laboratory diagnosis of critical hypofibrinogenemia (≤200 mg·dl-1 ) during pediatric cardiac surgery. Further studies are required to assess the impact of predictability of FFTEG on component transfusion during pediatric cardiac surgery.
