目的:研究呼吸操改善慢性阻塞性肺疾病(COPD)患者肺功能的机制。方法:对本院46例COPD患者随机分成对照组和治疗组,按常规内科治疗并对其有计划地进行健康知识教育。治疗组在常规内科治疗加康复指导基础上,增加呼吸操训练。测定治疗前后6分钟步行距离、血清白三烯、呼出气中一氧化氮浓度(fractional exhaled nitricoxide,FENO)。结果:治疗组较对照组6分钟步行能力改善,血清白三烯水平下降(P<0.05)、呼气NO含量下降(P<0.05)。结论:加强COPD患者的健康指导及呼吸操训练可改善患者肺功能状况,明显提高生活质量。
Objective: To study the mechanism of respiratory function in improving lung function in patients with chronic obstructive pulmonary disease (COPD). Methods: 46 COPD patients in our hospital were randomly divided into control group and treatment group. They were treated according to routine medical procedures and educated on their health knowledge systematically. The treatment group in the conventional medical treatment plus rehabilitation guidance, based on the increase of breathing exercises training. Determination of walking distance 6 minutes before and after treatment, serum leukotriene, exhaled nitric oxide concentration (FENO). Results: Compared with the control group, the patients in the treatment group improved their walking ability at 6 minutes, serum leukotriene level decreased (P <0.05) and the expiratory NO level decreased (P <0.05). CONCLUSIONS: Enhancing the health guidance and breathing exercises training for patients with COPD can improve pulmonary function status and significantly improve the quality of life.
