Respiratory system diseases in newborn infants remain a significant cause of neonatal morbidity and mortality worldwide. The immaturity of the neonatal lungs, insufficient surfactant production, weak respiratory muscles, and underdeveloped control of breathing contribute to the high susceptibility of newborns, especially premature infants, to respiratory disorders. Common conditions include respiratory distress syndrome, neonatal pneumonia, transient tachypnea, and meconium aspiration syndrome. Clinical manifestations such as tachypnea, chest wall retractions, nasal flaring, cyanosis, and irregular breathing patterns are critical indicators for early diagnosis. Timely recognition of these symptoms, combined with modern diagnostic techniques including chest radiography, blood gas analysis, pulse oximetry, and laboratory testing for infections, allows for effective management. Treatment strategies such as oxygen therapy, non-invasive ventilation, surfactant replacement, and antimicrobial therapy significantly improve outcomes. Preventive measures, including proper prenatal care, maternal health optimization, and hygienic neonatal care, further reduce the incidence and severity of respiratory disorders. Understanding the clinical characteristics, risk factors, and management strategies of respiratory system diseases is essential to enhance neonatal survival and long-term health outcomes.
