Abstract
in English, Chinese

Objective:To study the application value of humidified high flow nasal cannula （HHFNC） combined with visual laryngoscopy in the arytenoid cartilage dislocation. Methods:Twenty-nine patients with arytenoid cartilage dislocation were randomly double-blind into HHFNC group and general nasal catheter oxygen suction group, and the intraoperative and postoperative evaluation indicators, anesthesia-related indicators and postoperative vocal cord were compared. Results:There were statistically significant differences in intraoperative blood oxygen saturation, microstream end-tidal carbon dioxide partial pressure EtCO₂, respiratory rate and respiratory intervention times between the two groups （P<0.05）, and statistically significant differences in postoperative heart rate, oxygen saturation and respiratory rate （P<0.05）. After reduction, the voice disturbance index, the degree of voice abnormality, rough voice, breath sound, powerless pronunciation and catatonic pronunciation changed significantly after operation. Conclusion:HHFNC combined with visual laryngoscopy in the arytenoid cartilage dislocation has high anesthetic safety, good cooperation of patients, and good surgical effect.

目的：探讨湿化高流量鼻导管氧疗 （HHFNC） 配合可视喉镜在环杓关节脱位复位术中的应用价值。 方法：将29例环杓关节脱位患者随机双盲分为HHFNC组和普通鼻导管氧疗组，比较两组术中及术后评估指标、麻醉相关指标以及术前术后声带情况。 结果：两组术中血氧饱和度、微旁流二氧化碳分压、呼吸频率、呼吸干预次数的差异均有统计学意义（P<0.05），术后心率、血氧饱和度、呼吸频率的差异有统计学意义（P<0.05）。两组患者有效呼吸时长、麻醉苏醒时间及苏醒评分的差异有统计学意义（P<0.05）。复位后患者嗓音障碍指数、嗓音异常程度、粗糙声、气息声、无力样发音及紧张性发音术后较术前变化显著。 结论：HHFNC配合可视喉镜下环杓关节脱位复位术，麻醉安全性高，患者配合度好，手术效果良好。.
