目的:比较在清醒及诱导睡眠两种不同状态下,电子喉镜对阻塞性睡眠呼吸暂停低通气综合征(OSAHS)定位诊断结果的差异。方法:经多导睡眠监测确诊的98例OSAHS患者,分别在清醒状态及用咪唑安定诱导睡眠后用电子喉镜对其上呼吸道进行动态观察,以确定阻塞部位,并对两组结果进行比较。结果:98例患者在清醒状态下经电子喉镜定位诊断,存在多部位阻塞者占58.2%(57/98);而在诱导睡眠后存在多部位阻塞者占77.5%(76/98),两组差异有统计学意义(P<0.01)。结论:大部分的OSAHS患者上呼吸道存在多部位阻塞;在诱导睡眠状态下,阻塞部位要比清醒状态时多。
OBJECTIVE: To compare the difference of positioning diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS) with electronic laryngoscope under both awake and induced sleep states. Methods: Ninety-eight OSAHS patients diagnosed by polysomnography were enrolled in this study. Their upper respiratory tract was dynamically observed by electrical laryngoscope after awake and awakened by midazolam, respectively. The obstructed sites were identified and compared between the two groups. Results: 98 cases were diagnosed by electronic laryngoscope in awake state, accounting for 58.2% (57/98) in multi-site obstruction and 77.5% (76/98) in multi-site obstruction after induction of sleep. Two The difference was statistically significant (P <0.01). CONCLUSIONS: Most OSAHS patients have obstructed upper airway obstruction; more obstructive sites are induced during sleep inducement than during wakefulness.
