阻塞性睡眠呼吸暂停低通气综合征及鼾症患儿睡眠监测特点

Characteristics of polysomnogrphy in children with obstructive sleep apnea hypopnea syndrome and primary snoring

目的:分析儿童阻塞性睡眠呼吸暂停低通气综合征(OSAHS)和单纯鼾症的多导睡眠监测特点。方法:应用32导多导睡眠监测仪(PSG)对134例睡眠打鼾儿童例行整夜睡眠监测,并按照呼吸紊乱指数(AHI)对患者进行分组,分为单纯鼾症组(Ⅰ组)、轻度OSAHS组(Ⅱ组)、中度OSAHS组(Ⅲ组)和重度0SAHS组(Ⅳ组)。比较各组间的PSG检测结果。结果:与鼾症组相比,OSAHS儿童呼吸紊乱指数、微觉醒指数、呼吸暂停次数有显著性差异(P<0,05)。各组睡眠结构无显著性差异。结论:OSAHS对儿童睡眠结构影响较轻,睡眠结构相对完整。但在呼吸紊乱次数、微觉醒指数、呼吸暂停次数表现异常,且与病情相关;PSG是鉴别诊断儿童OSAHS与鼾症的重要方法,并对OSAHS的分型、病情评价有重要价值。

[Objective]o analyze the characteristrics of polysomnography(PSG) in children with primary snore and obstructive sleep apnea hypopnea syndrome(OSAHS).[Method]One hundred and thirty four children with sleep breathing disorder were studied by 32 guide PSG and analyzed by Polysmith,then they were classified according to the apnea hypopnea index(AHI) into four groups:primaiy snore group,mild OSAHS,moderate OSAHS and severity OSAHS.[Result]Compared with PS group,mere was statistically significant difference in the parameters such as apnea hypopnea index,total arousal index and apnea frequency(P < 0.05).The structure of sleep was no significant difference among the four groups.[Conclusion]The structure of sleep was little influencedin children with OSAHS,but the degree interrelates with apnea frequency,total arousal index and apnea hypopnea index;Confirmed diagnosis of the sleep disorders in chileren requires PSG recordings.
