Hemodynamics Of Different Volumes Of Red Blood Cell Transfusion In Preterm Infants
PEDIATRICS INTERNATIONAL(2021)
摘要
Background Although many controversies exist regarding the risk of red blood cell (RBC) transfusions, half of preterm infants born at <32 weeks of gestational age receive such transfusions because of anemia of prematurity. Because of the costs and risks associated with multiple transfusions, it has been suggested that a large transfusion volume reduces the number of transfusions. However, there have been persistent concerns that RBC transfusion might lead to volume overload.Methods We examined the impacts of large (20 mL/kg) compared to standard volume (15 mL/kg) transfusions on the hemodynamic variables of stable, electively transfused, preterm infants, by serially measuring echocardiographic parameters and plasma B-type natriuretic peptide levels.Results A total of 39 infants born at 2 weeks at the time of enrollment were randomly allocated to either a standard volume (15 mL/kg) or a large volume (20 mL/kg) group. Significant reductions in cardiac output and transient increases in plasma B-type natriuretic peptide levels were found after RBC transfusion in both the standard and large volume (20 mL/kg) groups. However, these changes were not significantly different between the two groups.Conclusions Large-volume transfusions could be tolerable in stable preterm infants with anemia.
