Objective: To test a new device designed to salvage red blood cells (RBCs) from blood samples drawn from preterm infants, with the intent of decreasing blood loss and lowering the requirements for RBC transfusions.
Design: A case-controlled pilot study was conducted in two Israeli neonatal intensive care units in large municipal hospitals. Twenty low-birthweight preterm infants were randomly and equally divided into the ErythroSave group or a control group. All blood tests in the study group (except for complete blood count and coagulation parameters) were obtained during the first week of life by the new device in the study group and by ordinary syringes in the control group. The main outcome measure was the total number of units of blood needed.
Results: The average volume of blood obtained for laboratory analyses from each infant was 27 mL in the ErythroSave group and 24 mL in controls (not significant). The average volume of transfused packed cells was 6.4 mL for the ErythroSave group and 21.3 mL for the controls (p = 0.008).
Conclusion: The use of ErythroSave for sampling blood significantly reduced blood transfusion requirements in premature infants compared to sampling by conventional syringes.

Introduction Respiratory distress syndrome (RDS) is a leading cause of morbidity and mortality among preterm infants, necessitating effective treatment strategies. This study compared the efficacy of Beractant (SURVANTA®) to Poractant alfa (CUROSURF®) in treating RDS in preterm infants admitted to Tawam Hospital in the UAE. Methodology This retrospective study included preterm infants from 23+0 to 36+6 weeks of gestation with a diagnosis of RDS and treatment by Beractant or Poractant alfa within 48 hours of life between January 2020 and March 2023.

Background: Intravenous lipid emulsions are an essential component of nutritional support for very preterm infants. Many neonatal intensive care units have transitioned from traditional soybean oil-only to fish oil-containing multicomponent lipid emulsions, but the neurodevelopmental implications have not been well-explored. The primary aim of this study was to assess extrauterine third trimester brain growth in very preterm infants supported with soybean oil-only compared to fish-oil containing multicomponent lipid emulsions; white matter development and neurobehavioral regulation at term were also investigated.

Background: Premature infants are at high risk for neonatal respiratory distress syndrome (RDS) and secondary infections. This study aims to investigate the association between immunoinflammatory markers-the systemic immune inflammation index (SII), systemic inflammation response index (SIRI), and neutrophil-to-albumin ratio (NAR)-and the risk of developing RDS in premature infants.
Methods: A total of 2164 premature infants were enrolled in this retrospective study.
Impact of Antenatal Corticosteroids on Cortisol and Glucose Homeostasis Levels in Preterm Neonates: A Meta-Analysis.

Pediatrics, K S Hegde Medical Academy, Mangaluru, IND.
Antenatal corticosteroids (ACS) are widely used to reduce respiratory distress syndrome (RDS) in preterm neonates, enhancing neonatal outcomes. However, the potential effects of ACS on other aspects of neonatal health, such as cortisol levels and glucose regulation, remain a concern. This study examines whether ACS administration impacts cortisol and glucose homeostasis in preterm infants by analyzing data from 14 selected studies.

Preterm birth, defined as delivery before 37 weeks of gestation, is a significant contributor to neonatal morbidity and mortality worldwide. Understanding the prevalence of preterm birth is critical to improving neonatal care, informing public health strategies, and supporting health care planning. The objective of this study was to explore the problem of preterm birth in Saudi Arabia by estimating the prevalence of preterm birth over a defined period of time.
