３０例慢性阻塞性肺病（ＣＯＰＤ）缓解期住院患者，体外膈肌起搏（ＥＤＰ）治疗２周后随机分为家庭继续治疗组１５例和停止治疗组１５例，分别于６周和１６周进行随访。继续治疗期间，其最大口腔吸气压（ＭＩＰ）、负荷呼吸时间（ＬＴ）、６ｍｉｎ行走距离（６ＭＷＤ）和膈肌移动度（ＤＭ）均有进一步改善（Ｐ＜００５），肺功能的改变不如呼吸肌功能明显，表现为ＶＣ、ＦＥＶ１、ＦＥＶ１／ＦＶＣ的增大。停止治疗组１６周后仅用６ＭＷＤ、ＦＥＶ１／ＦＶＣ和深呼吸时ＤＭ较治疗前有改善，其余肺功能和呼吸肌功能指标均降到治疗前水平。提示家庭ＥＤＰ继续治疗可巩固和进一步提高ＥＤＰ的疗效。
Thirty patients with chronic obstructive pulmonary disease (COPD) undergoing remission were enrolled. After EDP treatment for 2 weeks, they were randomly divided into 15 consecutive family continuation groups and 15 stop treatment groups, followed up for 6 weeks and 16 weeks respectively . The MIP, LT, 6MWD and diaphragmatic muscle mobility (DM) were further improved (P <005) and the changes of lung function Not as good as respiratory muscle function, manifested as VC, FEV1, FEV1 / FVC increase. After 6 weeks of treatment, only 6MWD, FEV1 / FVC and deep breathing DM improved after treatment, and the rest of lung function and respiratory muscle function indexes dropped to pre-treatment level. Tip home EDP continued treatment can consolidate and further improve the efficacy of EDP.
