Lung Ultrasound Score for Early Prediction of Bronchopulmonary Dysplasia in Preterm Newborns

Bronchopulmonary dysplasia (BPD) is one of the most common and severe complications of extreme prematurity, affecting approximately 40% of infants born before 28 weeks of gestation. Despite advances in neonatal care and improved survival rates for extremely preterm infants, the incidence of BPD remains high. BPD is associated with significant short- and long-term morbidity, including chronic respiratory impairment, pulmonary hypertension, recurrent respiratory infections, and neurodevelopmental sequelae. Current diagnosis of BPD is based on the need for respiratory support at 36 weeks postmenstrual age, limiting opportunities for early therapeutic intervention. Since structural lung injury may become irreversible within the first weeks of life, the identification of reliable early predictors of BPD is a major clinical priority. Lung ultrasound (LUS) is a non-invasive, radiation-free, bedside imaging technique increasingly used in neonatal intensive care units. The Lung Ultrasound Score (LUS) provides a quantitative assessment of lung aeration and has demonstrated utility in predicting several neonatal respiratory outcomes. Recent studies suggest that both LUS and pleural line abnormalities detected during the first weeks of life may be associated with the subsequent development of BPD, although evidence remains heterogeneous and no universally validated predictive method is currently available.
