在清醒状态下,喉梗阻引起喉喘呜不难诊断。在睡眠情况下,喉梗阻引起的喉喘鸣可被误诊为打鼾或呼吸暂停。作者报告3例睡眠时的喉梗阻,喉喘鸣病人,2例为Shy-Drager综合征,1例为喉功能障碍。2例因为病人不同意立即作气管切开术,在就诊后2天和14天死亡。另1例,及时作了气管切开术得以存活。 In the awake state, laryngeal obstruction caused by laryngeal wheeze is not difficult to diagnose. Throat wheeze caused by laryngeal obstruction may be misdiagnosed as snoring or apnea during sleep. The authors report three cases of laryngeal obstruction during sleep, patients with laryngeal wheeze, two with Shy-Drager syndrome and one with laryngeal dysfunction. Two patients died of tracheotomy immediately because of their disagreement on days two and fourteen days after the visit. Another case of timely tracheotomy to survive.
