我国的支气管哮喘防治指南[1-2]及全球哮喘防治创议(GINA)[3]中均指出:哮喘患者的症状(symptom)是指反复发作的喘息、气急、胸闷或咳嗽;哮喘的急性发作(acute exacerbation)是指哮喘的症状突然发生,或原有症状加重,以呼气流量降低为其特征,常因接触变应原、刺激物或呼吸道感染诱发[1-2]。笔者认为该哮喘急性发作的定义存在两个问题。首先,该定义没有客观的量化指标,临床医师既不能据此确定哮喘患者的症状是否是急性发作,也无法确定患者哮喘的控制水平。哮喘完全控制标准中至少包括:白天症状≤2次/周、无哮喘急性发作[1]。按照目前的定义,我们无法确定这些“白天症状”是否是“急性发作”。如果这些“白天症
In our country, guidelines for the prevention and treatment of bronchial asthma [1-2] and GINA [3] all point out that symptom in asthmatics refers to recurrent wheezing, shortness of breath, chest tightness or coughing; acute exacerbation of asthma (acute exacerbation) refers to the sudden onset of symptoms of asthma, or worsening of the original symptoms, characterized by reduced expiratory flow, often induced by exposure to allergens, irritants or respiratory infections [1-2]. I believe there are two problems with the definition of an acute exacerbation of asthma. First, there is no objective quantitative measure of this definition, and clinicians can neither determine if the symptoms of asthma are acute or determine the level of asthma control in patients. Complete asthma control standards include at least: Daytime symptoms ≤ 2 times / week, without acute asthma attacks [1]. According to the current definition, we can not determine whether these ”daytime symptoms“ are ”acute attacks.“ If these ”day disease
