【摘要】 目的：探索阻塞性睡眠呼吸暂停（OSA）引起日间过度嗜睡（EDS）患者的多导睡眠监测（PSG）特点。方法：选取2021年8月至2022年8月甘肃省人民医院睡眠医学中心门诊或住院的OSA引起日间过度嗜睡患者（ESS量表≥12分）42例，年龄、性别匹配的OSA不伴有嗜睡（ESS量表<12分）患者46例，探索OSA引起EDS患者的夜间睡眠特点。结果：OSA伴EDS组和OSA不伴EDS组比较，AHI、夜间ASpO₂、总睡眠时间、睡眠效率、N1期睡眠占比、N2期睡眠占比差异均无统计学意义（均P>0.05）。夜间LSpO₂、睡眠潜伏时间、觉醒指数、N3期睡眠比、R期睡眠比占比差异均有统计学意义（均P<0.05）。结论：OSA伴EDS患者表现出不同于OSA不伴EDS患者的PSG特点，其夜间缺氧更严重、觉醒次数更多、深睡眠比例更低。更多还原

【Abstract】 Objective:To investigate the characteristics of polysomnography, PSG in patients with Excessive daytime sleepiness（EDS） caused by obstructive sleep apnea（OSA）.Methods:Forty-two patients with obstructive sleep apnea（OSA） induced excessive daytime sleepiness（ESS≥12 points） were selected from the outpatients or inpatients of the Sleep Medicine Center of Gansu Provincial People′s Hospital between August 2021 and August 2022.Forty-six age-and sex-matched patients with OSA without drowsiness（ESS scale<12 points） were enrolled to explore the night sleep characteristics of OSA-induced EDS patients.Results:There were no significant differences in AHI,nocturnal ASpO₂,total sleep time, sleep efficiency, proportion of sleep in N1 phase and proportion of sleep in N2 phase between OSA group and OSA group without EDS（all P>0.05）.There were statistically significant differences in LSpO₂ at night, latent sleep time, wake index, N3 sleep ratio and R sleep ratio（all P<0.05）.Conclusion:The PSG characteristics of OSA patients with EDS were different from those of OSA patients without EDS,with more severe nighttime hypoxia, more awakenings, and lower proportion of deep sleep.更多还原
