摘要 目的:拟明确电刺激呼吸训练对COPD患者运动中动态过度充气程度的影响,并探讨其作用途径。方法:募集30例中重度且合并动态过度充气的慢性阻塞性肺疾病患者随机分成干预组(n=15例)与对照组(n=15例),对照组继续其原有的药物治疗方案,干预组在此基础上再进行为期12周,每周2次,每次30min的电刺激呼吸训练。结果:在进行12周的呼吸训练后,干预组在恒定功率自行车运动(80%个体最大运动功率)的等时点上动态过度充气程度减轻(深吸气量显著增加),而主观呼吸困难程度减轻、运动耐受时间明显延长,同时出现呼吸周期时间增加、呼气时间相对延长、通气效率与死腔通气量—潮气量比值改善及经口最大呼气压增加;而对照组未见类似改变。结论:电刺激呼吸训练可显著改善慢性阻塞性肺疾病患者运动诱导性动态过度充气并最终提高其运动耐受性。而其作用机制可能涉及患者的通气与换气功能。
