摘要
目的：探讨肺弥散功能测定在支气管哮喘和慢性阻塞性肺疾病鉴别诊断中的意义。方法：收集我院2010年1月-2011年3月呼吸科门诊、住院患者共112例，其中哮喘患者（A组）21例，慢阻肺患者（B组）47例，肺功能正常者44例作对照组（C组），检测3组患者的肺通气功能（RV／TLC、FEVl／预计值）和弥散功能（Dlco／VA、DLcoSB），对结果进行分析比较。结果：哮喘组和慢阻肺组FEVl／预计值均低于对照组（P〈0．05）；哮喘组弥散功能（Dlco／VA、DLcoSB）值与对照组比较无明显差异（P〉0．05），而慢阻肺组弥散功能值明显低于对照组及哮喘组（P〈0．05）。结论：肺弥散功能测定对哮喘与慢阻肺的鉴别诊断有重要价值。
Objective ： To explore the significance of lung diffusing function measurements for the differ ential diagnosis of bronchial asthma and chronic obstructive pulmonary disease. Methods ：112 out-patient and hospitalized cases of Respiration Department in our hospital from January 2010 to March 2011 were selected, including 21 asthma cases（groupA） ,47 COPD cases（groupB） and 44 control cases（groupC） . Pulmonary ven tilation function（ RV/TLC, FEV1/expected value） and lung diffusing function（ Dlco/VA ,DLco SB）measure ments were performed in the patients with asthma, COPD and control group, the results were analyzed and com pared in three groups. Results：The FEV1/expected value in the patients with asthma and COPD were obviously lower than that in the control group （ P 〈 0.05 ）. There was no obvious difference of the diffuse function value （Dlco/VA,DLco SB） between the asthma group and control group（P 〉 0.05） , only the diffuse function value in the COPD group was significantly lower than that in the control group and asthma group （P 〈 0.05 ）. Conclu sions：Lung diffusing function measurement has an important value in the differential diagnosis of asthma and COPD.
