Delgado–Corcoran C, et al. – The clinicians aimed to evaluate if red blood cell transfusion during the convalescent phase of the stage 1 palliation (S1P) to achieve higher hemoglobin levels (Hgb) was associated with benefits during the between stages (IS) including improved growth and decreased acute medical events. Their evaluation indicated that single ventricle (SV) infants after S1P, who were steadily recovering, did not benefit from late transfusion to raise their hemoglobin level at discharge.
