This is a randomized controlled trial that compares two different priming composition
(albumin vs. fresh frozen plasma) for extracorporeal circulation of pediatric patients under
10 kg of weight. The two approaches are both employed at the moment but there is actually no
evidence on the superiority of one over the other. This study is aimed to test the hypothesis
that Albumin is superior to fresh frozen plasma in terms of minor bleeding and transfusional
requirements.
