近年来,小气道(small airways)功能评价在哮喘等小气道阻塞性疾病中的应用引起了重视。哮喘患者小气道阻力可达总气道阻力的50%~90%,是哮喘气道阻塞的主要部分,与哮喘控制不佳、急性发作及预后密切相关[1-3]。小气道功能检测缺乏金标准,且部分方法较为复杂或有创,儿童难以配合[4]。而肺功能作为小气道功能检测的重要手段之一,尤为适用于儿童。故本文将就肺功能在儿童小气道功能检测中的应用及研究进展进行综述。
In recent years, the evaluation of small airways function has drawn great attention in the field of small airway obstructive diseases such as asthma. Small airway resistance in asthmatic patients can reach 50% -90% of total airway resistance and is a major component of airway obstruction in asthma, which is closely related to poor control of asthma, acute attack and prognosis [1-3]. Small airway function test lack of gold standard, and some methods are more complicated or invasive, children with difficulty [4]. The lung function as an important means of small airway function test, especially for children. Therefore, this article will review the application of lung function in children with small airway function test and research progress.
