This prospective, single-center study aimed to evaluate the platelet response during cardiopulmonary bypass (CPB) surgery in a large cohort of children up to 6 years of age.

The study recruited 60 children requiring CPB for surgical repair of congenital heart defects. The platelet count decreased throughout CPB surgery, but during the same period, platelet activity increased. The more pronounced decrease in platelet count observed in children younger than 1 year compared with that of children 1 to 6 years of age was not associated wi..View full abstract
