儿童阻塞性睡眠呼吸暂停低通气综合征患者睡眠呼吸监测分析

目的:分析儿童阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的多导睡眠监测特点。方法:采用32 导多导睡眠仪(PSG),Polysmith睡眠分析软件,按国际通用导联连结方法对45例睡眠打鼾儿童进行整夜监测, 比较OSAHS患儿(OSAHS组)与单纯打鼾儿童(单纯打鼾组)的PSG监测结果。结果:OSAHS组:平均年龄 (7.3±3.8)岁,平均体重(40.1±19.7)kg;非快速眼动期1、2、3 4期,快速眼动期所占时间的比例分别为(21.4 ±13.2)%、(43.1±13.7)%、(26.1±14.0)%和(9.4±6.0)%,与单纯打鼾组比较,差异无统计学意义(P> 0.05);OSAHS组平均呼吸暂停低通气指数为(12.8±8.1)次/h,呼吸暂停指数为(6.7±6.6)次/h,低通气指数 为(6.1±5.1)次/h。结论:OSAHS对儿童睡眠结构影响较轻,睡眠结构相对完整。

Polysomnography analysis in children

OBJECTIVE: To analyze the characteristics of Polysomnography (PSG) in children with obstructive sleep apnea-hypopnea syndrome(OSAHS). METHOD: Forty-five children with sleep breathing disorder were studied with 32 guide PSG and analyzed by Polysmith. PSG results of OSAHS children were compared with primary snore group. RESULT: The mean age of OSAHS children was(7.3 +/- 3.8) years and the mean body weight was (40.1 +/- 19.7) kg. The mean value of NREM stage 1, stage 2, stage 3+4 and REM stage was(21.4 +/- 13.2)%, (43.1 +/- 13.7)%, (26.1 +/- 14.0) % and (9.4 +/- 6.0) % respectively. The sleep structure between OSAHS group and primary snore group was not significant (P > 0.05). The mean value of AHI of OSAHS children was(12.8 +/- 8.1) h. AI was (6.7 +/-6.6)h, HI was(6.1 +/- 5.1)h. CONCLUSION: The sleep structure of children is prefect and mild effected by OSAHS.
