Lung Ultrasound in Neonatology: Revolutionizing the Diagnosis of Respiratory Distress Syndrome

Abstract

Neonatal respiratory distress remains a leading cause of morbidity and mortality in newborns, necessitating rapid and accurate diagnosis for timely intervention. Lung ultrasound (LUS) has emerged as a valuable, non-invasive, and radiation-free imaging modality for assessing neonatal respiratory conditions. This review explores the role of lung ultrasound in diagnosing common causes of neonatal respiratory distress, including respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), meconium aspiration syndrome (MAS), and pneumonia. The article discusses the characteristic sonographic patterns associated with each condition, such as the presence of lung consolidations, pleural line abnormalities, B-lines, and air bronchograms. Additionally, we highlight the advantages of LUS over traditional imaging techniques, such as chest X-rays, including bedside applicability, real-time assessment, and avoidance of ionizing radiation exposure. Limitations and challenges, including operator dependency and interpretation variability, are also addressed. This review underscores the growing evidence supporting the integration of lung ultrasound into routine neonatal care protocols and emphasizes the need for standardized training and guidelines to optimize its clinical utility.
