Abstract
Background: Pediatric patients are at high risk of massive bleeding after cardiac surgery under cardiopulmonary bypass (CPB). Fibrinogen is essential for coagulation; however, pediatric patients with congenital heart disease (CHD) present abnormal fibrinogen function. The pre- and post-operative fibrinogen level may affect the bleeding and transfusion amount in patients undergoing cardiac surgery. However, the relationship between plasma fibrinogen levels and the bleeding and transfusion amount in pediatric cardiac surgery remains unclear. This study aimed to assess the association of pre-CPB fibrinogen levels (PreFib) and post-CPB fibrinogen levels (PostFib) with postoperative bleeding and transfusion volume in pediatric cardiac surgery. Methods: We reviewed the medical records of 375 newborns and infants who underwent cardiac surgery under CPB for CHD. The primary endpoint was the correlation of the PreFib and PostFib values, as well as their difference (FibGap), with the bleeding and transfusion amount within 24 postoperative hours. Results: There was no correlation of the PreFib, PostFib, and FibGap values with the bleeding and transfusion amounts at postoperative 24 hours. However, patients with PreFib and PostFib values of <150 and <100 mg/dL, respectively, showed a significantly higher frequency of postoperative platelet (PLT) transfusion. In patients with complex CHD, PreFib showed a weak negative correlation with the bleeding amount at postoperative 24 hours and the number of PLT-transfused patients. Conclusions: Our findings suggest that in pediatric patients with CHD who cannot undergo point-of-care (POC) tests, those presenting PreFib and PostFib values of <150 and <100 mg/dL, respectively, have a significantly higher frequency of postoperative PLT transfusion. 2022 Translational Pediatrics.
