BACKGROUND Dyspnea, fatigue, and decline in sleep quality are symptoms of chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation programs have been shown to ameliorate dyspnea and fatigue. However, only a few studies have investigated the effects of pulmonary rehabilitation on the sleep quality of COPD patients. In this study, we analyzed the benefits of a pulmonary rehabilitation program to sleep quality and daytime somnolence in COPD patients. METHODS This study was a study of 30 moderate-severe COPD patients. All patients were evaluated by a pulmonologist and underwent polysomnography before participating in the study. For this study, we selected only ex-smokers and patients with sleep apnea were referred to the sleep clinic. These participants were prospectively recruited and not selected based on program completion. Before the start of the program, sleep quality and daytime somnolence of the participants were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS), respectively. Rehabilitation program consisted of muscular training sessions conducted at the gym 3 times per week for 12 weeks. After rehabilitation program, the patients were reassessed and their sleep quality and daytime somnolence were reevaluated using the PSQI and the ESS, respectively. RESULTS Before rehabilitation, PSQI evaluation revealed that 73% of the participants had poor sleep quality, and ESS evaluation showed that 86.7% of the participants experienced daytime somnolence. After pulmonary rehabilitation, the PSQI specifically improved in terms of subjective sleep quality and sleep duration (< 0.001), habitual sleep efficiency (0.001), and sleep latency and sleep alterations (0.002) and there was also improvement in the ESS (< 0.001). CONCLUSION Pulmonary rehabilitation program of gradually increasing intensity has the potential to provide sleep-related benefits to patients with COPD who have poor sleep quality and daytime somnolence.

肺康复中慢性阻塞性肺疾病患者睡眠质量和日间嗜睡的评价


背景技术呼吸困难、疲劳和睡眠质量下降是慢性阻塞性肺病(COPD)的症状。肺部康复计划已被证明可以缓解呼吸困难和疲劳。然而，只有少数研究调查了肺康复对慢性阻塞性肺病患者睡眠质量的影响。在这项研究中，我们分析了肺康复计划对慢性阻塞性肺病患者睡眠质量和白天嗜睡的益处。方法 本研究对 30 名中重度 COPD 患者进行了研究。所有患者在参与研究之前均由肺科医生进行评估并接受多导睡眠图检查。在这项研究中，我们仅选择了戒烟者和被转诊至睡眠诊所的睡眠呼吸暂停患者。这些参与者是前瞻性招募的，而不是根据项目完成情况选择的。在项目开始之前，分别使用匹兹堡睡眠质量指数（PSQI）和爱普沃斯嗜睡量表（ESS）评估参与者的睡眠质量和白天嗜睡情况。康复计划包括每周在健身房进行3次肌肉训练，持续12周。康复计划结束后，对患者进行重新评估，并分别使用 PSQI 和 ESS 重新评估他们的睡眠质量和日间嗜睡情况。结果康复前，PSQI评估显示73%的参与者睡眠质量较差，ESS评估显示86.7%的参与者白天嗜睡。肺康复后，PSQI 在主观睡眠质量和睡眠持续时间 (< 0.001)、习惯性睡眠效率 (0.001) 以及睡眠潜伏期和睡眠改变 (0.002) 方面都有明显改善，ESS 也有改善 (< 0。001）。结论 逐渐增加强度的肺康复计划有可能为睡眠质量差和白天嗜睡的慢性阻塞性肺病患者提供与睡眠相关的益处。试用注册 Registro Brasileiro de Ensaios Clínicos (ReBEC) RBR62b4z2。
