摘要
目的 :探索在我国不同程度慢性阻塞性肺疾病 (COPD)患者中应用 MRC分级的可能性。方法 :对 34例不同程度 COPD患者同时进行肺功能检测分级 (FEV1 % Pred)和 MRC分级 ,采用等级分组资料秩和检验、等级相关检验和同一对象两种实验的 χ2检验检测 MRC分级的可能性。结果 :MRC分级有显著统计学意义 (P<0 .0 1) ,肺功能分级和 MRC分级明显相关 ,两种分级无统计学差异 ,且重度 COPD中两种分级法有较好的一致性。结论 :MRC分级简单、实用 ,在基层医院或不具备肺功能检测的地方可单独使用。
Objective: To discuss the possibility for using MRC dyspnea scale in Chinese COPD patients.Methods: 34 COPD cases in different grade were classified by pulmonary function scale (FEV 1%Pred) and MRC dyspnea scale. The possibility of MRC dyspnea scale was tested by using rank-sum test for grouped data, rank correlation analysis and chi square test of same object two test.Results: MRC dyspnea scale had obvious statistic significance (P<0.01). There was a clear correlation between the pulmonary function scale and MRC dyspnea scale. No visible difference was found in two scale methods. There was good consistency for both scale methods in severe COPD cases.Conclusion: MRC dyspnea scale is a simple and useful mehtod. It can be used alone in basal hospital or without spirometer.
