支气管舒张试验在儿童哮喘诊治中的价值探讨

The value of bronchodilation test in the diagnosis and treatment of children with asthma

哮喘是儿童时期最常见的慢性呼吸道疾病,其基本病理生理特征为可逆性气流受限。支气管舒张试验是发现气流受限可逆程度的手段之一,在哮喘的诊治中发挥着重要作用。但儿童有其特殊性,不同年龄段儿童适宜不同的肺功能检测手段,相应的支气管舒张试验阳性界值不同于成人,并且支气管舒张试验在评估控制情况、预测治疗反应及未来风险等方面也发挥一定作用。该文就多种肺功能检查方法的支气管舒张试验及其在儿童哮喘监测管理中的应用进行综述。

Asthma is the most common chronic respiratory disease in children,which is mainly pathophysiologically charactrized by reversible airflow limitation.Bronchodilation test is one of the methods to evaluate the reversible degree of airflow limitation,which plays an important role in the diagnosis and treatment of asthma.However,different pulmonary function testing methods should be employed for children of different ages due to their specific characteristics.The corresponding cut-off value for positive bronchodilation test for children is different from that for adults.Bronchodilation test can also evaluate the control situation,and predict therapeutic responses and future risks.In this article,bronchodilation test of different pulmonary function testing methods and its application in the assessment and management of pediatric asthma were reviewed.
