脑卒中后睡眠结构变化的研究

目的观察脑卒中后患者睡眠结构变化的特点。方法采用多导睡眠图对53例脑卒中后患者进行整夜睡眠描记,并与对照组比较。分析相关睡眠参数。结果脑卒中后与对照组比较多项睡眠指标均有显著性差异(P<0.05);脑卒中后患者睡眠潜伏期延长,总睡眠时间减少,入睡后醒觉次数增多,睡眠效率低,快眼动(REM)睡眠潜伏期缩短,REM睡眠时间和REM活动度减少。结论脑卒中后患者睡眠结构发生改变,睡眠时间减少,睡眠质量差。REM睡眠潜伏期、REM睡眠时间和REM睡眠活动度是评估脑卒中后患者的神经功能缺损康复的客观参数。

The macrostructure of sleep in patients with stroke

Objective To study the characteristics of sleep parameter changes for the patients of stroke.Methods 53 patients in stroke and 30 age and gender-matched healthy controls were investigated in this study.All of them were fit with the requirement of this trial.53 patients in stroke and 30 control were investigated by polysonmography(PSG) for one night.Sleep stage was analyzed by doctor.The parameters of sleep macrostructure were calculated later by computer and were brought into the statistical analysis according patients in stroke and controls.Results The prolonged sleep latency,decreased total sleep time,increased frequency of awakenings or arousals during sleep,lowered sleep efficiency,shortened rapid eye movement(REM) sleep latency,decreased REM sleep time and REM activity were shown in the patients at recovery stage of stroke(P<0.05).Conlusion It is suggested that not only sleep decreased in quantity,but also accompanied with changes in quality for the patients after stroke.REM sleep latency,REM sleep time and REM activity are objective indexes to estimate the recovery for stroke.
