Bronchopulmonary dysplasia (BPD) is a common respiratory disease in preterm infants, and systemic treatment with glucocorticoids is commonly used to prevent and treat BPD. However, the short-term and long-term complications, especially the impact on the nervous system, should not be ignored. Inhaled glucocorticoids and airway glucocorticoids supported by lung surfactants are newly proposed administration regimens, ye the efficacy and safety of the regimen still need to be verified by more clinical data and follow-up results. This paper discusses the advantages and disadvantages from three aspects including systemic glucocorticoids, inhaled glucocorticoids, and intra-airway administration of glucocorticoids in the form of alveolar surface-active substances.
