目的探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)儿童及鼾症儿童多导睡眠图的特点及多导睡眠图对儿童睡眠障碍的临床应用价值。方法对2002年12月至2004年9月新疆医科大学第一附属医院儿科74例OSAHS儿童及62例同年龄组原发性鼾症儿童进行整夜多导睡眠(PSG)监测,并进行比较,观察呼吸紊乱指数、觉醒次数、周期性腿动指数、睡眠最低血氧饱和度等16项指标。结果与鼾症组相比,OSAHS儿童周期性腿动指数、呼吸紊乱指数、平均血氧饱和度、最低血氧饱和度、发生在非快速眼动期的呼吸紊乱指数有显著性差异(P<0.05)。结论PSG是鉴别诊断儿童OSAHS与鼾症的重要方法,通过对PSG各项指标进行比较,强调PSG是诊断儿童睡眠有关疾患,特别是OSAHS的分型、病情评价的有用和重要方法。

Value of polysomnography in children with obstructive sleep apnea hypopnea syndrome and primary snoring

Objective To explore the polysomnography(PSG) characteristics of obstructive sleep apnea hypopnea syndrome(OSAHS) and primary snoring(PS) in children and clinical value of PSG in children with sleep disorders.Methods From Dec.2002 to Sep.2004 Medical University First Hospital 74 children with OSAHS and 62 with primary snoring were analyzed in Xinjiang,every patient being monitored with PSG for 7 hours at night for 16 parameters,including the apnea and hypopnea index(AHI),periodic leg movement index(PLMI),and the lowest oxygen saturation(LSaO2),etc.The parameters of the 2 groups were compared.Results Compared with PS group,there was statistically significant difference in the parameters such as PLMI,AHI,LSaO2,the moderate oxygen saturation(MSaO2)and apnea hypopnea index in NREM(P<0.05).Conclusion PSG is an importment method to distinguish PS from OSAHS in children.Confirmed diagnosis of the sleep disorders in chileren requires PSG recordings.
