1978年始有作者以多导睡眠描记检查法(polysomnography,PSG)用于诊断阻塞性睡眠呼吸暂停(OSA)。为探索PSG的应用范围,对93例疑为OSA病人作了回顾性分析,年龄18月～12岁,测定PSG时,观察了心电图、脑电图、眼电图、血氧分析、颏舌肌、肋间肌肌电图、口鼻气流量等,并注意身高、体重、扁桃体大小与OSA的关系。结果,93例中34例确诊为OSA,44例为正常PSG,另15例为胃食道返流,中枢性呼吸暂停,阻塞性低氧症等。在性别、年龄和临床表现方面0SA组与正常PSG组无显著差别。黑种人0SA发病率明显高于白种
In 1978, some authors used polysomnography (PSG) to diagnose obstructive sleep apnea (OSA). To explore the scope of application of PSG, 93 patients with suspected OSA were retrospectively analyzed, ranging in age from 18 months to 12 years. Electrocardiogram, electroencephalogram, electrooculogram, oximetry, genioglossus , Intercostal muscle EMG, mouth and nose flow, etc., and pay attention to height, weight, tonsil size and OSA relationship. Results, 34 of 93 cases were diagnosed as OSA, 44 cases of normal PSG, the other 15 cases of gastroesophageal reflux, central apnea, obstructive hypoxia and so on. There was no significant difference between 0SA group and normal PSG group in gender, age and clinical manifestations. Black 0SA incidence was significantly higher than white
