Article Synopsis
  • Platelet transfusions are given to preterm infants to prevent bleeding, but recent studies showed higher risks of mortality and major bleeding with transfusions at a higher platelet count threshold of 50 × 10/L compared to 25 × 10/L.
  • A prospective observational study across 64 neonatal intensive care units in 22 European countries was conducted to assess current platelet transfusion practices, which included tracking transfusion rates, indications, and patient outcomes.
  • The findings indicated that the lower transfusion threshold of 25 × 10/L is being adopted in practice, though there's considerable variation in transfusion volumes and rates, highlighting the need for further research to optimize these practices.

Importance: Red blood cell (RBC) transfusions are frequently administered to preterm infants born before 32 weeks of gestation in the neonatal intensive care unit (NICU). Two randomized clinical trials (Effects of Transfusion Thresholds on Neurocognitive Outcomes of Extremely Low-Birth-Weight Infants [ETTNO] and Transfusion of Prematures [TOP]) found that liberal RBC transfusion thresholds are nonsuperior to restrictive thresholds, but the extent to which these results have been integrated into clinical practice since publication in 2020 is unknown.

Objective: To describe neonatal RBC transfusion practice in Europe.

Introduction: Intraventricular hemorrhages remain a major problem in neonatology, because their complications affect neonatal morbidity, mortality, and long-term neurodevelopmental outcomes.

Aim: The aim of this project was to prevent intraventricular hemorrhage in premature infants during their first days of life in a neonatal intensive care unit (NICU).

Methods: This pre- and post-implementation clinical audit project used the JBI Evidence Implementation Framework and was conducted in a tertiary-level Spanish NICU with a consecutive sample.

Objectives: To survey practices of iron and recombinant human erythropoietin (rhEpo) administration to infants born preterm across Europe.

Study Design: Over a 3-month period, we conducted an online survey in 597 neonatal intensive care units (NICUs) of 18 European countries treating infants born with a gestational age of <32 weeks.

Results: We included 343 NICUs (response rate 56.

Background: Currently, the treatment of anemia in preterm infants is based on packed red blood cell (RBC) transfusions from adult donors. Oxygen (O2) is mainly transported to the tissues bound to hemoglobin (Hb). In extremely low gestational age neonates (ELGANs), fetal hemoglobin (HbF), which has a higher affinity for O2, represents up to 95% of circulating hemoglobin.

Fetal hemoglobin (HbF) has a higher affinity to oxygen than adult hemoglobin, allowing for a slower oxygen transfer to peripheral tissue, creating a microenvironment conducive to adequate fetal development . However, most preterm infants receive packed red blood cell transfusions from adult donors leading to a drastic nonphysiological descent of circulating HbF. We hypothesized that this drop could enhance oxygen delivery to peripheral tissues generating a hyperoxic pro-oxidant environment.

Currently, the first line treatment of persistent ductus arteriosus (PDA) is either indomethacin or ibuprofen. However, the potentially life-threatening side effects associated to their use have prompted physicians to look for alternative options. The incorporation of paracetamol as an alternative to ibuprofen in the management of PDA is still based on insufficient clinical evidence.

Neonatal acute myocardial infarction is an uncommon entity. We describe the case of a 4-day-old term baby who presented with respiratory distress and distal acrocyanosis. The chest radiograph demonstrated cardiomegaly without pleural effusion, and examination revealed hepatomegaly.
