摘　　要：目的:对177例中老年慢性失眠患者的多导睡眠图监测(PSG)数据进行回顾性分析,观察中老年慢性失眠症患者的睡眠特征,为临床治疗提供依据。方法:选取2018年4月至2019年4月潍坊市中医院睡眠医学科收治的中老年慢性失眠患者177例作为研究对象。提取PSG报告中的客观数据如性别、年龄、总睡眠时间(TST)、睡眠后清醒时间(WASO)、清醒次数、睡眠潜伏期(SL)、REM潜伏期、N1期、N2期、N3期、R期以及AHI、觉醒次数等,结合患者的主观感受,采用Excel统计软件对研究数据进行统计分析。结果:51.94%患者总睡眠时间在6~8 h内;入睡后清醒次数小于10次的仅占2.26%,10~40次的占80%。74.01%的患者觉醒次数在30~110次之间;81.36%的患者睡眠潜伏期小于30 min;51.41%的患者N3期完全消失,68.93%的患者N3期<3%。92.66%患者N3期比例减少。R期在正常范围内的占29.81%。66.67%的患者R期比例在15%~30%,即正常或接近正常。结论:中老年失眠患者PSG有如下特征:1)N3期严重减少;2)患者对睡眠的感知与PSG所得总睡眠时间和睡眠潜伏期明显不一致,与清醒次数,特别是醒睡转换密切相关;3)睡眠潜伏期不能反映患者是否感觉入睡困难,设想提出“临床睡眠潜伏期”“醒睡转换频率”“清醒指数”“临床清醒期”和“PSG清醒期”5个概念来对睡眠感知进行客观化研究。Objective:The PSG data of 177 middle-aged and elderly patients with chronic insomnia were analyzed retrospectively.Through the analysis of PSG data,the sleep characteristics of middle-aged and elderly patients with chronic insomnia were observed,and the methods of objectification of sleep perception were explored to provide a basis for clinical treatment.Methods:Extracted from PSG report objective data such as gender,age,total sleep time(TST),awake after sleep time(WASO),waking,sleep latency(SL),the incubation period of REM,N1,N2,N3 stage,R period and AHI,awakening times data,combined with the patient′s subjective feeling,to Excel table data for statistical analysis.Results:The total sleep time of 51.94%patients was within 6~8 hours;Only 2.26 percent were awake less than 10 times after falling asleep,and 80 percent were awake between 10 and 40 times.74.01%of the patients had awakenings between 30 and 110 times.81.36%of the patients had a sleep latency of less than 30 min.In 51.41%of the patients,N3 completely disappeared,and in 68.93%,N3<3%,which was equal to or close to complete disappearance.The proportion of 92.66%patients with stage N3 decreased.Conclusion:PSG has the following characteristics in middle-aged and elderly patients with insomnia:The severe reduction of N3 phase.The patients′perception of sleep is significantly inconsistent with the total sleep time and sleep latency obtained by PSG,and is closely related to the number of waking times,especially the waking and sleeping conversion.The sleep latency does not reflect whether the patient feels difficulty falling asleep.Five concepts of“clinical sleep latency period”,“waking and sleeping conversion frequency”,“wakefulness index”,“clinical wakefulness period”and“PSG wakefulness period”were proposed to objectively study sleep perception.
