摘    要:目的探讨深吸气量(IC)与稳定期慢性阻塞性肺病患者(COPD)运动耐力的相关性。方法对人选的30例稳定期COPD患者,每日吸入噻托溴胺粉雾剂18ug,连续观察12周。于第1、43、85天检查呼吸困难的评分,6分钟行走距离(6MWD),一秒钟用力呼气量(FEV1),用力肺活量(FVC),深吸气量(IC)等指标,比较用药前后各变量变化的统计学意义及肺功能各变量与6MWD的相关性。结果用药后FEV1和FEV1/FVC均有所改善,其中FEV1的改善要好于FEV1/FVC改善,但与用药前比较,均无显著差异(P〉0.05);用药后6周、12周IC较用药前比较有显著增加(t=4.596、5.405,P均〈0.01),6MWD用药后6周、12周较用药前有显著提高(t=4.628、6.207,P均〈0.01);用药后6周、12周呼吸困难评分的下降较用药前比较有显著差异(z=4.433、4.026,P均〈0.001);回归分析显示IC的变化与6MWD的变化均有较好的相关性(r=0.900、0.873,P均〈0.01)。结论本研究的结果提示比较其他肺功能指标,伦的改变与呼吸困难和运动耐力的改变有更好地相关性,IC的测定有助于COPD患者治疗效果及生活质量的预测。

Abstract:Objective To explore the relationship between the inspiratory capacity(IC) and exercise capacity in the stable COPD.Methods 30 patients with stable COPD were treated by inhaling 18 ug tiotropium a day,followed up 12 weeks.Respiratory difficulty was scored on day 1,43 and 85,6 minute-walk-distance(6MWD),FEV1,FEV1/FVC and IC were measured.The changes of these variables were statistically analyzed and the relationship were studied between the pulmonary function and 6MWD,after receiving tiotropium in 6 weeks an...
Keywords:inspiratory  chronic obstructive pulmonary disease  exercise capacity
