summary . The objective of this study was to investigate how a red blood cell transfusion volume of 15 or 20 mL kg −1 body weight affects the total number of administered transfusions and neonatal complications in premature infants born before 32 gestational weeks. In this observational study, we analysed clinical data from two cohorts of 218 and 241 premature infants admitted to two neonatal centres which used the same transfusion guideline and product, but different transfusion volumes. Outcome parameters were the number of administered transfusions and the composite outcome of bronchopulmonary dysplasia, retinopathy of prematurity, intraventricular haemorrhage and mortality. The proportion of transfused infants was significantly lower (59 vs. 77%) in the centre using a lower transfusion volume of 15 mL kg −1 . In infants born between a gestational age of 24 0/7 weeks and 27 6/7 weeks. a similar proportion received transfusions in both centres, with an equal number of transfusions per infant. In infants born between a gestational age of 28 0/7 weeks and 31 6/7 weeks, the proportion of transfused infants (49 vs. 74%) was significantly higher in the centre using a larger transfusion volume. In these infants, transfusion with 20 mL kg −1 resulted, however, in a mean reduction of one transfusion episode per infant. The higher proportion of transfused infants was associated with a higher pre‐transfusion haematocrit in less ill infants, suggesting the use of different triggers based on clinical grounds. Composite clinical complications were similar in both cohorts. Clinical neonatal outcome was similar disregard of a higher proportion of transfused patients and a higher total amount of RBC transfused in one of the centres. A larger transfusion volume of 20 mL kg −1 prolonged the interval until next transfusion and can reduce donor exposure in infants born between a gestational age of 28 0/7 weeks and 31 6/7 weeks.
