In recent years, the management of respiratory diseases related to preterm birth has received extensive attention.In 2021, the American Thoracic Society brought together multidisciplinary experts in respiratory, neonato-logy, otolaryngology, sleep medicine, radiology and nursing specialties to develop Guidelines for outpatient respiratory management in infants, children, and adolescents with post-preterm respiratory disease (hereinafter referred to as the " Guideline" ), aiming to provide evidence-based medical evidence for standardized outpatient management of respiratory diseases associated with preterm birth at different ages.The Guideline was interpreted and summarized so that pediatric clinicians could correctly diagnose and treat these diseases, and understand and implement standardized outpatient management on the basis of evidence.
