目的调查汽车司机的睡眠呼吸情况，分析睡眠呼吸暂停综合征与交通事故的关系。方法随机抽取100名公交汽车司机应用多导睡眠监测仪进行整夜睡眠呼吸监测。结果100名司机中有28名AHI〉5次／h，其中轻度15名，中度7名，重度6名，夜间血氧饱和度均明显下降。结论睡眠呼吸暂停患者由于睡眠期间缺氧，使睡眠质量下降，可影响白天的认识能力和反应能力，是发生交通事故的重要危险因素。

Objective To investigate breathing disorders in bus drivers and analyse the relationship between traffic accidents and drivers with sleep apnea syndrome （SAS）. Methods 100 consecutive patients were recruited at random to complete overnight polysomnography and sleep questionnaires. Results 25 of the 100 were found to have SAS with an AHI of 〉 5 （ie, averaging more than 5 such events per hour of sleep） ,including 15 cases with mild SAS,7 cases with moderate SAS and 6 cases with severe SAS. There was a signicant fall in nocturnal saturation in them. Conclusion There is higher percentage of patients with SAS in automobile drivers. Sleepiness due to long-term hypoxemia at at night causes daytime cognitive impairments and reaction fatigue, which is the potential reason for occurrence of traffic accidents.
