呼吸困难鉴别指数在慢性阻塞性肺病的应用

目的:探讨呼吸困难鉴别指数(dyspnea differentiation index,DDI)在慢性阻塞性肺病(chronic obstructive pulmonary disease,COPD)病情评估中的应用。方法:测定62例COPD患者(吸烟者32例、非吸烟者30例)的PaO2和PEF值,根据Rajesh K. Ailani等创立的公式计算呼吸困难鉴别指数DDI,用治疗前后的DDI与二组(吸烟组、非吸烟组)气急患者改善情况分别进行对比,观察其相关性。结果:DDI值与吸烟组COPD患者的临床严重度分级标准呈明显相关性,与非吸烟组COPD患者的病情改善相关不确定。结论:用DDI判别吸烟组COPD病情是一种敏感、简便可行的方法,值得临床上应用。

Objective:To investigate the differential index of difficulty in breathing(dyspnea differentiation index,DDI) in patients with chronic obstructive pulmonary disease(chronic obstructive pulmonary disease,COPD) patients to assess the application.Methods:62 cases of COPD patients(smokers,32 cases,30 cases of non-smokers) and PEF values of PaO2,Rajesh K.Ailani according to the formula,such as the creation of the differential index of difficulty in breathing DDI,before and after treatment with the DDI and the Second group(smokers,non-smoking group) to improve the situation in patients with dyspnea,respectively,compared to observe the correlation.The results:DDI value in patients with COPD and smoking group clinical severity was significantly related to grading standards,and with non-smoking group of COPD patients to improve the relevance of uncertainty.Conclusion:The use of DDI-smoking group discriminant disease COPD is a sensitive,simple and feasible,should be applied clinically.
