Objective To investigate the effect of audio - visual segregation , a simply nursing methods, on the sleep quantity, quality and structure of patients who Check - in ICU. Methods 75 cases selected patients were randomly divided into observation, through muscle tension, Pittsburgh sleep quality index scale and EEG monitoring three kinds of methods, audio-visual isolated group and control group observation and statistics processing. Results between the two groups, the sleep quality and sleep time has a significant difference (P<0.01), sleep structure of audio - visual segregation group maintained at normal level, but in control group, the period NREM3-4 and REM significant reduced, and there was a significant difference in two groups. Conclusion The method of physical isolation guarantees the quality of sleep ICU patients with normal structure effect significantly, popularization.%目的 研究单纯的视听隔离护理方法对ICU患者睡眠的量、质和结构的影响.方法 对75例入选患者随机分组后,通过肌张力观察法、匹兹堡睡眠质量指数量表和脑电图监测3种方法,对视听隔离组(视听隔离组)和对照组观察观察结果进行统计学处理.结果 两组间睡眠时间、睡眠质量有统计学差异(P＜0.01),睡眠结构视听隔离组保持了正常的分期结构,对照组快波睡眠(REM)和慢波睡眠(NREM)3～4期有显著性减少,和视听隔离组有显著性差异.结论 物理隔离的方法在保证ICU患者睡眠的质量和结构方面效果显著,有着较大的应用价值.
