A very strict guideline reduces the number of erythrocyte transfusions in preterm infants

Abstract
Background and Objectives Benefits of adopting restrictive guidelines for erythrocyte transfusions are still controversial. the objective of this study was to verify if a very strict guideline could reduce erythrocyte transfusions in preterm infants without adverse outcomes.Materials and Methods Two prospective cohorts of neonates with gestational age < 37 weeks and birth weight < 1500 g were studied. Neonates born in Period 1 were submitted to a strict guideline for erythrocyte transfusions. in Period 2, a new stricter protocol was introduced. Infants of both periods were compared regarding number of transfusions and clinical outcome.Results the median number of transfusions decreased from 2 (1 to 14) in Period 1 to 1 (1-9), P = 0.001, in Period 2. the linear regression multivariate analysis showed that the implementation of the stricter guideline was associated with a reduction in the number of transfusions received by patients by 0.55 (95% confidence interval: -0.08; -1.02) units/patients. Number of apnea episodes, weight at 28 days of life and days of hospital stay were similar in both periods. Intra-hospital death was lower in Period 2.Conclusion A very strict guideline reduced the number of erythrocyte transfusions in preterm infants, without threatening their clinical course.Universidade Federal de São Paulo, Dept Pediat, Div Neonatal Med, BR-04037002 São Paulo, BrazilUniversidade Federal de São Paulo, Dept Med, Div Hematol & Hemotherapy, BR-04037002 São Paulo, BrazilUniversidade Federal de São Paulo, Dept Pediat, Div Neonatal Med, BR-04037002 São Paulo, BrazilUniversidade Federal de São Paulo, Dept Med, Div Hematol & Hemotherapy, BR-04037002 São Paulo, BrazilWeb of Scienc
