睡眠呼吸暂停综合征(sleep apneasyndrome,SAS)亦称阻塞性睡眠呼吸暂停综合征(obstruction sleep apnea syndrome,OSAS),系在睡眠时出现严重打鼾、阵发性吸气后呼吸暂停(通常指口鼻腔气流中止在10秒钟以上)以及白昼嗜睡(daytime hypersomnolence)等为特征的一种综合征群。近年文献虽有报告,但临床医师尚不十分熟悉。一、病因及发病机理睡眠时导致严重打鼾及呼吸暂停的病理生理变化是上呼吸道通道的部分或暂时性完全阻塞;其病理解剖部位则主要发生在口咽部、包括咽壁、舌根以及软腭诸肌所形成的咽腔。睡眠时呼吸障碍的原因可分为两大类,即中枢性与周围性。前者的病变主要在中枢神经系统,睡
Sleep apnea syndrome (SAS), also known as obstruction sleep apnea syndrome (OSAS), is a severe snoring during sleep and apnea after paroxysmal aspiration (usually referred to as the nasopharynx Airflow stopped more than 10 seconds) and daytime sleepiness (daytime hypersomnolence) and so on. Although there are reports in recent years, clinicians are not yet very familiar with it. First, the etiology and pathogenesis of sleep leading to severe snoring and apnea pathophysiological changes in the upper respiratory tract is part or temporary complete obstruction; the pathological anatomy is mainly in the oropharynx, including the pharyngeal wall, tongue base and soft palate The pharynx formed by the muscle. The causes of sleep disorders can be divided into two categories, namely, central and peripheral. The former lesions mainly in the central nervous system, sleep
