Children with single-ventricle physiology do not benefit from higher hemoglobin levels post cavopulmonary connection: Results of a prospective, randomized, controlled trial of a restrictive versus liberal red-cell transfusion strategy*

Children with single-ventricle physiology do not benefit from a liberal transfusion strategy after cavopulmonary connection. A restrictive red blood cell transfusion strategy decreases the number of transfusions, donor exposures, and potential risks in these children. Larger studies with clinical outcome measures are needed to determine the transfusion threshold for children post cardiac repair or palliation for congenital heart disease.
