多导睡眠图在儿童阻塞性睡眠呼吸暂停低通气综合征及鼾症中的应用

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 discuss the status, characteristics and causes of obstructive dystocia in celph-present. Method We retrospectively analyzed the 925 eases of obstructive dystocia with celph-present in 6667 deliveries in 1986 in Tianjin Central Obstetrics and Gynecology Hospital ,and compared them with 148 cases in 4098 deliveries in 2004. Result Persistent oceiput transverse position and persistent occiput posterior position were the main causes which leaded to obstructive dystocia in both periods. While in the year 2004, there was an increasing trend of the obstuctive dystocia due to the elder para and immortal malformations of fetus. Conclusion Closely observing the progress of lair stage and the descent of fetal head is the key method for early diagnosis of obstructive dystocia.
