简易肺功能测定在支气管哮喘诊断和病情评估中的意义

Value of simple pulmonary function test in diagnosis and illness evaluation of patients with bronchial asthma

目的探讨简易肺功能检测在支气管哮喘(哮喘)诊断和病情评估中的意义。方法哮喘患者64例分为哮喘完全控制(A组,10例)、部分控制(B组,28例)和未控制(C组,26例)三组,以36例健康人(D组)作为对照,分别行简易肺功能检测,分析哮喘患者肺功能的特点。结果A、B、C组第1秒用力呼气量占预计值百分比(FEV_1%pred)、第1秒用力呼气量占用力肺活量百分比(FEV_1/FVC)及呼气峰值流速(PEF)均低于D组(P<0.05),且随哮喘严重程度的增加而逐渐降低(P<0.05)。结论简易肺功能测定有助于哮喘患者的诊断和病情评估。

Objective To explore the significance of simple pulmonary function test in the diagnosis and illness evaluation of the patients with bronchial asthma.Methods Sixty-four patients with bronchial asthma were assigned into three groups of A（with well controlled asthma,10cases）,B（with partly controlled asthma,28cases）and C（with uncontrolled asthma,26cases）.Thirty-six healthy volunteers were recruited as the controls（group D）.The simple pulmonary function tests were performed and the characteristics of pulmonary function was analyzed in the patients with asthma.Results The FEV_1%pred and FEV_1/FVC ratio in groups of A,B and C were significantly lower than those in group D（P0.05）and so did the peak expiratory flow rate（PEF）,which became severe as the severity of asthma enhanced（P0.05）.Conclusion The simple pulmonary function tests are helpful in the diagnosis and illness evaluation of the patients with bronchial asthma.
