喘息是婴幼儿下呼吸道感染的常见症状之一。因婴幼儿气道结构和功能尚未发育成熟,气道血管黏膜较丰富,发生喘息的机会远较成人为多[1]。喘息只是一个症状名称而非疾病诊断,根据预后的不同分为一过性早期喘息、持续性早发喘息及晚发喘息,主要包括的疾病有毛细支气管炎、各种喘息性肺炎及支气管哮喘。已知糖皮质激素具有降低气道高反应性和气道炎症的效应,并能改善肺功能,修复损伤的气道上皮,促进气道纤毛的生长。吸入糖皮质激素不仅能使更多哮喘患者达到良好或完全控制,且副反应少,在全球哮喘防治策略和中
Breathing is one of the common symptoms of lower respiratory tract infections in infants and young children. Because infants and young children airway structure and function have not yet mature, airway vascular mucosa is more abundant, wheezing opportunities are far more than adults [1]. Breathing is only a symptom of the disease rather than the diagnosis of the disease, according to the prognosis is divided into transient early wheezing, persistent early onset of wheezing and late wheezing, the main diseases include bronchiolitis, various asthmatic pneumonia and bronchial asthma. Glucocorticoids are known to have the effect of reducing airway hyperresponsiveness and airway inflammation, improving lung function, repairing damaged airway epithelium, and promoting airway ciliary growth. Inhaled corticosteroids not only enable more asthma patients to achieve good or complete control, and fewer side effects, in the global strategy for the prevention and treatment of asthma
