Eur Respir J:吗啡对晚期COPD患者呼吸困难和运动耐力的影响

2017-10-20 xing.T MedSci原创

口服立即释放的吗啡可以改善一些患者的劳力性呼吸困难和运动耐力,但并不是所有的慢性COPD成年患者。因此,基于实验室的CPET可以帮助确定最有可能受益于吗啡的COPD患者。

近日,呼吸疾病领域权威杂志Eur Respir J上发表了一篇研究析文章,在这项研究中,研究人员旨在评估吗啡对晚期慢性阻塞性肺疾病(COPD)患者劳力性呼吸困难和运动耐力的影响。

在一项随机交叉试验中,研究人员比较了20名晚期COPD和慢性呼吸困难综合征的患者口服速释吗啡与安慰剂对恒载心肺功能运动试验(CPET)期间生理和知觉反应的急性效应。

与安慰剂组相比,吗啡可以减少劳力呼吸困难的时间1.2±0.4Borg单位,并且增加运动耐力时间2.5±0.9min(P≤0.014)。在运动时,吗啡可以降低通气量1.3±0.5L•min-1和呼吸频率2±0.9 次•min-1(均有P≤0.041)。与安慰剂组相比,吗啡减少劳力性呼吸困难的时间≥1Borg单位的患者有11名(应答者)和<1Borg单位的患者有9名(无应答者)。参与者的基线特征,包括肺功能和心肺适能,在应答者和无应答者之间相似。由于无法忍受呼吸困难,应答者相比于无应答者停止增加CPET的比例更高为:82 vs. 33%(P=0.028)。

由此可见,口服立即释放的吗啡可以改善一些患者的劳力性呼吸困难和运动耐力,但并不是所有的慢性COPD成年患者。因此,基于实验室的CPET可以帮助确定最有可能受益于吗啡的COPD患者。
