失眠症者睡眠的主观评估和多导睡眠图对比分析

目的：探讨失眠症患者对睡眠评估的心理特征。方法：应用多导睡眠图对５０例失眠症患者进行整夜睡眠描记，次日早晨起床后询问夜间睡眠情况，并与２２名正常人进行对比分析。结果：与对照组比较、失眠症组睡眠潜伏期长，睡眠时间减少，睡眠效率低（Ｐ〈０．０１）；失眠症主观评估的睡眠潜伏期，总睡眠时间和睡眠效率与多导睡眠图结果比较具有显著不一致（Ｐ〈０．０５￣０．０１）。结论：失眠症组不但睡眠质量低于正常人，而且有着

Comparative Analysis of Subjective Estimation and Polysomnography of Sleep in Patients with Insomnia

Objective: To investigate the psychological characteristics of sleep estimation of the patients with insomnia Methods: The all-night polysomnography recording was conducted in 50 patients with insomnia and 22 normal controls The sleep latency, total sleep time and sleep efficiency were rated after getting up the next morning The results were analyzed by t-test Results: Compared with normal controls, the insomnia group had prolonged sleep latency, shortened sleep time, and low sleep efficiency (p<0 01) The sleep latency, total sleep time and sleep efficiency acquired from subjective estimation were significantly not consistent with the results of polysomnography (p<0 05 or 0 01) Conclusions: The insomnia patients not only have lower sleep quality, but also present a tendency to overestimate the sleep latency and underestimate the sleep time
