Whole-body perfusion improves intraoperative transfusions in neonatal aortic arch surgery.

Whole-body perfusion is the combination of lower body perfusion and antegrade cerebral perfusion. This perfusion technique is used in some centres when performing aortic arch reconstruction surgery in neonates and infants. Several studies have shown intra- and postoperative benefits of this technique. However, no studies have analysed the impact it may have on the transfusion of blood products and coagulation factors. We retrospectively analysed 65 consecutive neonates and infants who underwent aortic arch reconstruction surgery from January 2014 to July 2020. Patients operated from 2014 to 2017 underwent surgery with antegrade cerebral perfusion; in patients who underwent surgery from 2017 to 2020 a whole-body perfusion strategy was used. Demographic, intra- and postoperative parameters were compared as well as intraoperative blood product and coagulation factor transfusions, chest-tube output in the first 24 h and postoperative bleeding complications. Both groups required intraoperative transfusion of red blood cells, fresh frozen plasma, and platelets, as well as substitution of coagulation factors. The amount of transfused volumes of red blood cells, fresh frozen plasma and platelets (P-values 0.01, <0.01 and <0.01) and intraoperative transfusions of fibrinogen and von Willebrand factor were significantly lower in the whole-body perfusion group (P-value 0.04 and <0.01). A whole-body perfusion strategy may lead to fewer intraoperative blood product and coagulation factor transfusions when compared to antegrade cerebral perfusion alone in neonates and infants undergoing complex aortic arch reconstruction surgery.
