Background: Preterm infants are at risk of developing both intraventricular hemorrhage (IVH) and anemia of prematurity. Several studies reported an association between early postnatal red blood cell (RBC) transfusion and IVH, however the timing and causality between these two remains unclear.
Aims: To describe the temporal sequence between administration of early RBC transfusion (within the first week of life) and diagnosis of IVH in very preterm infants.
