BACKGROUND Poor sleep is prevalent in lung transplant recipients and affects quality of life negatively. To improve quality of sleep, it's important to identify the causes of poor sleep. We conducted a survey to identify the reasons for poor sleep quality in the recipients. METHODS We surveyed lung transplant recipients (2003-2010) at Baylor College of Medicine/The Methodist Hospital lung transplant center. We used a compilation of questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), Berlin Questionnaire, Epworth Sleepiness Scale (ESS) and Short Form 36 (SF36). Descriptive analysis was performed on the responses. RESULTS Of the 167 participants, 54 responded (32.3%) with mean age 60.6 years (SD 9.8), 48% male, and a mean post-transplant body mass index (BMI) of 27 (SD 4.7). The responders reported a long mean sleep latency of 33.2 min (SD 32.5), poor sleep quality (74% with PSQI score > 5), excessive daytime sleepiness (ESS > 9 in 29%), poor physical QOL with SF36 mean score of 41.3 (SD 9.4), and high risk for OSA (48.2%). About 30% and 72% reported sleep initiation and maintenance insomnia, respectively. The poor sleep quality was due to "getup to go to bathroom" (85%), "cough or snore loudly" (33%), "have pain" (27.8%), and "feel too cold" (27.8%). Furthermore, 5% reported "Can't breathe comfortably" as reason for poor sleep. CONCLUSIONS The recipients reported poor sleep and quality of life. The non-respiratory complaints were important factors for poor sleep. Attention to these factors may help to outline better management strategies to improve sleep in lung transplant recipients.

非呼吸不适是肺移植后睡眠不佳的主要原因。

背景技术差的睡眠在肺移植接受者中普遍存在，并且对生活质量产生负面影响。为了改善睡眠质量，重要的是找出睡眠不足的原因。我们进行了一项调查，以确定接受者睡眠质量差的原因。方法我们调查了贝勒医学院/卫理公会医院肺移植中心的肺移植受者（2003-2010年）。我们使用了一系列的问卷调查表，包括匹兹堡睡眠质量指数（PSQI），柏林问卷，爱泼华嗜睡量表（ESS）和简短表格36（SF36）。对响应进行描述性分析。结果在167名参与者中，有54名（32.3％）有反应，平均年龄为60.6岁（SD 9.8），男性为48％，平均移植后身体质量指数（BMI）为27（SD 4.7）。响应者报告说，他们的长期平均睡眠潜伏期为33.2分钟（标准差32.5），睡眠质量较差（74％，PSQI得分> 5），白天过度嗜睡（ESS> 9，占29％），身体QOL较差，SF36平均得分为41.3。 （SD 9.4）和OSA的高风险（48.2％）。分别约有30％和72％的人报告睡眠开始和维持失眠。睡眠质量差的原因是“起床去洗手间”（85％），“大声咳嗽或打sn”（33％），“疼痛”（27.8％）和“感觉太冷”（27.8％）。此外，有5％的人报告“不能舒适地呼吸”是睡眠不足的原因。结论接受者报告睡眠和生活质量较差。非呼吸不适是睡眠不足的重要因素。
