摘　　要：目的探讨重度阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者睡眠结构的变化。方法 100例经PSG确诊为重度OSAHS的患者(呼吸暂停低通气指数AHI>40),采用统计学方法对其睡眠结构、AHI以及微觉醒指数进行分析。结果快速眼动(REM)相所占睡眠时间百分比(13.97±6.56)%;非快速眼动S1+S2相所占睡眠时间百分比(75.32±10.31)%;S3+S4相所占睡眠时间的百分比(2.98±2.37)%。AHI指数为(62.36±15.46)次/h,微觉醒指数为(47.24±16.75)次/h,且两者具有显著相关性(r=0.856,P<0.01)。结论重度OSAHS患者S1+S2所占睡眠时间明显增加,S3+S4和REM所占睡眠时间的百分比显著降低,睡眠结构明显改变。Objective To explore the reorganization of sleep patterns in patients with severe obstructive sleep apnea hypopnea syndrome（OSAHS）. Methods The sleep patterns, apnea-hypopnea index（AHI）, and arousal index of 100 patients with severe OSAHS（AHI〉40） diagnosed by polysomnography were analyzed. Results The percentage of REM, S1＋S2, and S3＋S4 were（13.97 ±6.56）%,（75.32 ±10.31）%, and（2.98 ±2.37）%, respectively. AHI and arousal index were（62.36 ±15.46）/h and（47.24 ±16.75）/h,respectively. There was significant correlation between AHI and arousal index（r=0.856,P〈0.01）Conclusion REM and S3＋S4 were reduced, while S1＋S2 were increased in patients with severe OSAHS, suggesting the sleep architecture was reorganization.
