Methods Between December 2009 and June 2010, 84 patients with stable COPD were enrolled. Lung function (FEV1, IC, IC/TLC) ,6 minute walk-test (6MWT) and St George′s respiratory questionnaire (SGRQ) were examined. The relationship among FEV1, IC, IC/TLC, and the results of 6MWT and SGRQ by Pearson correlation analysis. Results There was no linear correlation between 6MWT and FEV1 （r=0.14，Pgt;0.1）, and 6MWT and FEV1≥60% （r=0.16，Pgt;0.1）. There was positive correlation between 6MWT and IC （r=0.317，Plt;0.01）, and 6MWT and IC/TLC （r=0.274，Plt;0.01）. There was negative correlation between SGRQ and FEV1 （r=-0.307，Plt;0.01）; and no linear correlation between SGRQ and IC （r=-0.001，Pgt;0.25）, and SGRQ and IC/TLC （r=-0.003，Pgt;0.25）. Conclusion In stable COPD patients, IC may be more accurate than FEV1 in refection of exercise tolerance while FEV1 may be more sensitive than IC in evaluation of dyspnea.
【摘要】目的 探討重癥胸外傷的救治。方法 2003年8月-2008年10月救治重癥胸外傷176例,進行總結(jié)分析。結(jié)果 采用胸腔閉式引流、胸腔穿刺、剖胸探查術、損傷臟器修補、呼吸機輔助呼吸等治療。治愈153例(86.9%)；死亡23例(13.1%)。結(jié)論 重癥胸外傷早期正確診斷急救,妥善處理合并傷是關鍵。
