74例儿童多导睡眠仪监测结果及临床资料分析

目的 探讨儿童阻塞性睡眠呼吸暂停低通气综合征（Obstructive sleep apnea hypopnea syndrome，OSAHS）的临床特点及诊断。方法对74名疑诊OSAHS患儿的临床资料包括睡眠相关呼吸紊乱病史、身高、体重、专科检查腺样体扁桃体等及多导睡眠仪（Polysomnography，PSG）监测结果进行分析。结果依PSG结果将病例分为非OSAHS组[阻塞性呼吸暂停指数（Obstructive apneaindex，OAI）〈1次／h，以下“指数”单位同，略去]12例和OSAHS组[OAI≥1，或呼吸暂停低通气指数（Apnea hypopneaindex，AHI）≥5，伴最低血氧饱和度（Lowest pulse oxygen saturation，LSpO2）〈92％]62例。OSAHS组与非OSAHS组儿童在临床表现、专科体格检查、体质指数（Bodymassindex，BMI）等方面比较差异无统计学意义。结论临床表现及专科体格检查不能确诊OSAHS患儿，PSG是鉴别儿童睡眠相关呼吸紊乱的重要手段；肥胖不是儿童OSAHS的主要病因。

Analysis of polysomnography outcomes and clinical data in seventy-four children

Objective To discuss the clinical feature and diagnosis of pediatric obstructive sleep apnea hypopnea syndrome（OSAHS）. Methods Collected the clinical data of 74 suspected OSAHS children - including history of sleep related breathing disorder, body height, weight and specialized examinations of tonsils and adenoid, before performing polysomnography（PSG）. Results According to the outcomes of PSG, these children were divided two groups： non- OSAHS group （obstructive apnea index, OAI 〈 1/h） , 12 cases, and OSAHS group（ OAI≥1/ h, or apnea hypopnea index, AHI ≥ 5/h assoc2ated the lowest pulse oxygen saturation, LSpO2 〈 92% ）, 62 cases. The two groups had no statistically significant differences in clinical manifestations, specialized examinations and body mass index （BMI）. Conclusion The clinical manifestations and specialized examinations can＇ t reliably distinguish children with OSAHS from those with simple snore. PSG plays an important role in exact diagnosis of pediatric sleep related breathing disorder; obesity is not the main cause of pediatric OSAHS.
