摘要 目的通过慢性阻塞性肺病和支气管哮喘患者肺弥散功能的比较,探讨其在临床的鉴别和诊断作用。方法测定64例慢性阻塞性肺病患者,32例支气管哮喘患者和30例正常人一秒时间肺活量/用力肺活量(FEV1/FVC)、残气容积/肺总量(RV/TLC)和弥散功能(DLco)(实测值/预计值)。测定结果在两组患者之间和与正常人之间进行比较。结果慢性阻塞性肺病和支气管哮喘患者一秒时间肺活量/用力肺活量(FEV1/FVC)明显低于正常人组,与正常人比较(P<0.01)差异有显著性意义。残气容积/肺总量(RV/TLC)明显高于正常人组,与正常人比较(P<0.01)差异有显著性意义。慢性阻塞性肺病患者的弥散功能(DLco)值明显下降,与正常人和支气管哮喘患者比较(P<0.01)差异有显著性意义。结论测定肺弥散功能有助于慢性阻塞性肺病和支气管哮喘的鉴别和诊断。
