缩唇-膈式呼吸操对缓解期肺心病患者的康复疗效

目的评价缩唇-膈式呼吸操对缓解期肺心病患者的康复疗效。方法对符合慢性肺心病及缓解期诊断标准的患者88例,随机分成锻炼组46例和对照组42例,锻炼组进行缩唇-膈式呼吸操,对照组口服安慰剂。两组于开始前和3个月后分别进行PaO2和PaCO2、肺功能、6min行走距离、内皮素-1水平和生存质量的评定。结果锻炼组结束后各项指标的改善与锻炼前比较有显著差异性,P<0.05。而对照组各项指标服安慰剂前后无明显变化。结论缩唇-膈式呼吸操对缓解期肺心病患者动脉血气、肺功能、运动能力、血浆内皮素-1及生存质量等均有重要影响。

Observation on recovery effects of pursed lips &diaphragm type breathing exercises to patients with chronic cor pulmonale in recovery period

Objective To evaluate recovery effects of pursed lips &diaphragm type breathing exercises to patients with chronic cor pulmonale in recovery period.Method 88 patients with chronic cor pulmonale in recovery period were randomized into 2 groups, exercise group(46 cases) and control group(42 cases).The exercise group does pursed lips &diaphragm type breathing exercises.The control group takes placebo. To valuate PaO2, PaCO2, lung function , 6 minutes walking distance(6MD), the level of the plasma endothelin-1 and quality of life of patients before two groups beginning and after two groups end.Result The PaO2, lung function( VC?FEV1%) and 6 MD were significantly higher, the PaCO2 and the level of the plasma endothelin-1 were significantly lowered and the quality of life was significantly improved after rehabilitation treatment, P< 0.05. They were not improved in the control group.Conclusion Pursed lips &diaphragm type breathing exercises is able to improve PaO2, PaCO2, lung function , 6 minutes walking distance(6 MD), the level of the plasma endothelin-1 and quality of life of patients with chronic cor pulmonale in recovery period.
