Lung Ultrasound Score Progress in Neonatal Respiratory Distress Syndrome

BACKGROUND AND OBJECTIVES: The utility of a lung ultrasound score (LUS) has been described in the early phases neonatal respiratory distress syndrome (RDS). We investigated as tool to monitor status preterm neonates throughout course RDS. METHODS: Preterm neonates, stratified 3 gestational age cohorts (25–27, 28–30, and 31–33 weeks), underwent at weekly intervals from birth. Clinical data, support variables, major complications (sepsis, patent ductus arteriosus, pneumothorax, persistent pulmonary hypertension neonate) were also recorded. RESULTS: enrolled 240 infants total. had significantly different LUS patterns. There was significant correlation between ratio oxygen saturation inspired admission, increasing with (b = ?0.002 [P < .001] 25–27 weeks; b ?0.006 28–30 ?0.012 weeks). Infants higher already birth (12 interquartile range 13–8 vs 8 12–4 control group; P .001). In 25 30 weeks’ gestation, 7 days life predicted bronchopulmonary dysplasia an area under curve 0.82 (95% confidence interval 0.71 93). CONCLUSIONS: affected by RDS, trajectory is dependent, correlates oxygenation status, predicts dysplasia. this population, useful, bedside, noninvasive status.
