缩唇腹式呼吸训练联合膈肌起搏对老年稳定期中重度COPD患者康复进程的影响

Effect of lip-contracting abdominal breathing training combined with diaphragmatic pacing on rehabilitation of elderly patients with moderate to severe COPD in stable stage

【目的】探究缩唇腹式呼吸训练联合膈肌起搏对老年稳定期中重度慢性阻塞性肺疾病(COPD)患者康复进程的影响。【方法】选取老年稳定期中重度COPD患者91例,按照随机数字表法分成对照组(n=44)和观察组(n=47)。对照组予以缩唇腹式呼吸训练,观察组予以缩唇腹式呼吸训练联合膈肌起搏。比较两组治疗前后动脉血气分析、肺功能、运动耐力的变化。【结果】治疗后,观察组pH和PaO_(2)水平高于对照组(P<0.05),PaCO_(2)水平低于对照组(P<0.05);观察组第一秒用力呼气容积(FEV1)、用力肺活量(FVC)、FEV1/FVC水平高于对照组(P<0.05);观察组6 min步行距离(6MWT)高于对照组、Borg评分低于对照组(P<0.05)。【结论】缩唇腹式呼吸训练联合膈肌起搏可提高老年稳定期中重度COPD患者肺功能,改善动脉血气分析,缓解患者呼吸困难症状,增加运动耐力。

【Objective】To explore the effect of lip-contracting abdominal breathing training combined with diaphragm pacing on rehabilitation process of elderly patients with moderate to severe chronic obstructive pulmonary disease(COPD)in stable stage.【Methods】A total of 91 elderly stable COPD patients were randomly divided into control group(n=44)and observation group(n=47)according to the random number table method.The control group was given lip contraction abdominal breathing training,and the observation group was given lip contraction abdominal breathing training combined with diaphragm pacing.The changes of arterial blood gas analysis,lung function and exercise endurance were compared between the two groups before and after treatment.【Results】After treatment,pH and PaO_(2) levels in observation group were higher than those in control group(P<0.05);PaCO_(2) level was lower than that in control group(P<0.05).The levels of forced expiratory volume in one second(FEV1),forced vital capacity(FVC)and FEV1/FVC in observation group were higher than those in control group(P<0.05).The 6 min walking distance(6MWT)of the observation group was higher than that of the control group,and Borg score was lower than that of the control group(P<0.05).【Conclusion】Lip-contracting abdominal breathing training combined with diaphragm pacing can improve lung function,arterial blood gas analysis,relieve dyspnea and increase exercise endurance in elderly patients with moderate and severe COPD.
