ABSTRACT
BACKGROUND: Anemia of prematurity (AOP) is prevalent among very low birth weight infants (VLBWIs). Red blood cell (RBC) transfusions, while necessary for managing AOP, have been linked to adverse neonatal outcomes.
METHODS: This retrospective study analyzed the medical records of 98 VLBWIs (24-31 weeks gestation) admitted to the Chungbuk National University Hospital neonatal intensive care unit. Infants were categorized based on RBC transfusion status and birth weight (< 1000 g and 1000-1499 g). Clinical outcomes between the groups were compared.
RESULTS: Of the 98 infants, 35 (35.7%) received RBC transfusions. The RBC transfusion group exhibited significantly higher incidence of bronchopulmonary dysplasia ([Formula: see text]moderate), prolonged invasive mechanical ventilation, intraventricular hemorrhage (grades 1-2), extended time to full enteral feeding, and extended total parenteral nutrition (TPN) compared to the non-RBC transfusion group. Birth weight was inversely correlated with the number of RBC transfusions (p = 0.004). The duration of invasive mechanical ventilation and TPN administration were positively associated with the number of RBC transfusions (p < 0.001 and p = 0.025, respectively).
CONCLUSIONS: The RBC transfusion group experienced more comorbidities than the non-transfusion group. Birth weight, duration of invasive ventilation, and duration of TPN were associated with the number of RBC transfusions. Strategies to reduce the duration of invasive ventilation and early discontinuation of TPN may mitigate the need for RBC transfusions in AOP.
