Although red blood cell transfusion can be life\u2010saving in these preterm infants, it has been associated with higher rates of complications including necrotizing enterocolitis, bronchopulmonary dysplasia, retinopathy of prematurity and possibly abnormal neurodevelopment. The main objective of this review is to assess current red blood cell transfusion practices in the neonatal intensive care unit, to summarize available neonatal transfusion guidelines published in different countries and to emphasize the wide variation in transfusion thresholds that exists for red blood cell transfusion. This review also addresses certain issues specific to red blood cell processing for the neonatal population including storage time, irradiation, cytomegalovirus (CMV) prevention strategies and patient blood management. Future research avenues are proposed to better define optimal transfusion practice in neonatal intensive care units.<\/jats:p>","DOI":"10.1111\/vox.13036","type":"journal-article","created":{"date-parts":[[2020,11,27]],"date-time":"2020-11-27T17:16:57Z","timestamp":1606497417000},"page":"366-378","source":"Crossref","is-referenced-by-count":78,"title":["Neonatal red blood cell transfusion"],"prefix":"10.1111","volume":"116","author":[{"given":"Andr\u00e9anne","family":"Villeneuve","sequence":"first","affiliation":[{"name":"Division of Neonatology CHU Sainte\u2010Justine Montr\u00e9al QC Canada"},{"name":"Department of Pediatrics Universit\u00e9 de Montr\u00e9al Montr\u00e9al QC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"Arsenault","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Universit\u00e9 de Montr\u00e9al Montr\u00e9al QC Canada"},{"name":"Division of Haematology CHU Sainte\u2010Justine Montr\u00e9al QC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Lacroix","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Universit\u00e9 de Montr\u00e9al Montr\u00e9al QC Canada"},{"name":"Division of Pediatric Intensive Care CHU Sainte\u2010Justine Montr\u00e9al QC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marisa","family":"Tucci","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Universit\u00e9 de Montr\u00e9al Montr\u00e9al QC Canada"},{"name":"Division of Pediatric Intensive Care CHU Sainte\u2010Justine Montr\u00e9al QC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,11,27]]},"reference":[{"key":"e_1_2_10_2_1","unstructured":"LauW:Neonatal and Pediatric Transfusion: Clinical guide to transfusion[Internet].Canadian Blood Services.2017.
