Three patients underwent laryngeal and tracheal surgeries under apneic conditions using transnasal humidified rapid-insufflation ventilatory exchange. Transcutaneous carbon dioxide (CO2) levels were recorded throughout the apneic period to detect rates of CO2 rise. Conventional airway management was initiated after 15 minutes of apnea with either tracheal intubation or jet ventilation. No patient experienced oxygen desaturation <97%. The average rate of transcutaneous CO2 rise (1.7 mm Hg/min) was higher than previously reported using this technique. This suggests a need for further investigation into the utility of transnasal humidified rapid-insufflation ventilatory exchange for airway surgery and adequate ventilation during apnea.
三名患者在无呼吸状态下接受了喉和气管手术，采用经鼻湿化快速充气通气交换。在整个无呼吸期间记录经皮二氧化碳（CO2）水平，以检测CO2上升速率。在无呼吸15分钟后，通过气管插管或喷射通气开始常规气道管理。没有患者出现氧饱和度低于97%的情况。经皮CO2上升的平均速率（1.7毫米汞柱/分钟）高于此前使用该技术的报道。这表明有必要进一步研究经鼻湿化快速充气通气交换在气道手术及无呼吸期间充分通气方面的效用。
