To analyze arousal response of Polysomnography (PSG) in children with obstructive sleep apnea-hypopnea syndrome (OSAHS).
Fourty-eight children with sleep disorder were studied with 32 guide Polysomnography and analyzed by Polysmith. Sleep structure and arousals of preschool-aged and school-aged children with OSAHS were compared with those of primary snore patients.
The mean value of AHI of preschool aged children with OSAHS was (10.6+/-8.9) h, of AI was (4.0+/-7.1) h, of HI was (6.6+/-4.6) h; The sleep structure between OSAHS group and primary snore group was not significant (P > 0.05). The mean value of ArI with AHI was (8.2+/-5.9) h, of ArI with LM was (19.6+/-5.8) h, whole ArI was 49.3+/-20.4 in preschool-aged children with OSAHS; The mean value of ArI with AHI was (7.6+/-6.3) h, of ArI with LM was (14.3+/-7.6) h, whole ArI was 49.9+/-14.9 in school-aged children with OSAHS. Those of OSAHS children were higher than that of primary snore patients (P < 0.05).
Although OSAHS in children is characterized by a restless sleep, the structure is perfect and mildly affected by OSAHS. The ArI with AHI, with LM and the whole ArI in OSAHS children is higher than those of primary snore patients.
分析阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患儿多导睡眠图（PSG）的觉醒反应。
对48例睡眠障碍儿童进行32导多导睡眠图检查，并采用Polysmith软件进行分析。将OSAHS学龄前儿童和学龄儿童的睡眠结构及觉醒情况与原发性鼾症患儿进行比较。
OSAHS学龄前儿童的平均呼吸暂停低通气指数（AHI）为（10.6±8.9）次/小时，平均呼吸暂停指数（AI）为（4.0±7.1）次/小时，平均低通气指数（HI）为（6.6±4.6）次/小时；OSAHS组与原发性鼾症组的睡眠结构差异无统计学意义（P>0.05）。OSAHS学龄前儿童AHI相关的平均觉醒指数（ArI）为（8.2±5.9）次/小时，最低血氧饱和度（LM）相关的ArI为（19.6±5.8）次/小时，总ArI为49.3±20.4；OSAHS学龄儿童AHI相关的平均ArI为（7.6±6.3）次/小时，LM相关的ArI为（14.3±7.6）次/小时，总ArI为49.9±14.9。OSAHS患儿的上述指标高于原发性鼾症患儿（P<0.05）。
儿童OSAHS虽以睡眠不安稳为特征，但其睡眠结构尚完善，受OSAHS影响较轻。OSAHS患儿AHI相关、LM相关及总ArI均高于原发性鼾症患儿。
