【摘要】目的 调查长时间血液透析对血液透析患者睡眠质量的影响。 方法  通过问卷调查和收集临床资料相结合的方法，选取首都医科大学附属北京友谊医院血液净化中心40例维持性血液透析患者进行研究，应用AIS量表、匹兹堡睡眠质量指数(Pittsburgh sleep quality index，PSQI)量表、Epworth Sleepiness Scale(ESS)量表调查患者的睡眠质量，根据睡眠质量情况将患者配对分组为普通透析组(Hemodialysis HD)20人和长程透析组）6个月的临床试验。 结果   LSHD组患者KT/V明显高于HD组患者，P 值＜0.05，2组患者在PSQI量表、ESS量表评分差异存在显著性， LSHD组患者睡眠质量明显高于HD组，P 值＜0.05。 结论 维持性血液透析的患者 多存在睡眠质量下降的问题，增加透析剂量可以改善睡眠质量。

【Abstract】 Objective To investigate the sleep quality in patients on maintenance hemodialysis of long session hemodialysis. Methods sleep quality was evaluated using the Athens Insomnia Scale (AIS), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS). Forty patients on maintenance hemodialysis were equally divided into two groups according to their scores of sleep quality: hemodialysis (HD) group, and long session hemodialysis (LSHD) group. In HD group, hemodialysis was performed 4h a session and three times a week. In LSHD group, hemodialysis was delivered 8h a session and three times a week. The test lasted for 6 months. Results Kt/V was significant higher in LSHD group than in HD group (P＜0.05). Significant differences in PSQI, ESS scores were found between the two groups.  Conclusion Sleep disorder is very common in hemodialysis patients. Increase of hemodialysis dose can improve sleep quality.
