摘　　要：目的评估新型可视喉罩CTrach在颈椎病手术中的应用价值。方法80例颈椎手术行全身麻醉者采用CTrach喉罩系统置入通气，并引导气管插管，记录喉罩置入所需时间、喉罩通气的成功率、气管导管首次插入的成功率、总的成功率、喉罩直视下声门显露的比率以及从喉罩置入到气管导管成功插入所需的时间。结果所有患者均可置入喉罩，其中2例通气效果不满意；喉罩通气满意者78例中有5例首次插管未成功。除2例喉罩通气效果不满意和3例3次试插未成功外，其余75例最后都可以在CTrach喉罩引导下完成气管导管的插入，从开始操作到完成置入气管导管的平均时间为192s（156—273s）。结论CTrach喉罩系统可以在直视下进行调整，暴露喉头的位置，提高插管的成功率，避免一些不必要的损伤，在颈椎手术的气道管理中具有一定的应用价值。Objective To evaluate the application of the LMA CTrach for airway management during cervical spine surgery. Methods A total of 80 patients received cervical spine surgery under general anesthesia. During the operation, the LMA CTrach was used for ventilation and insertion of endotracheal tube. The authors recorded the time of laryngeal mask insertion, the success rate of ventilation, the success rate of the first attempt of endotracheal intubation, the number of attempts of endotracheal intubation, the time from insertion of the LMA CTrach to the completion of tracheal intubation. Results The LMA CTrach insertion was successfully completed in all but 2 patients. In 78 patients with good ventilation, the first attempt of endotracheal intubation failed in 5 patients. Except for unsuccessful ventilation in 2 patients and intubation failure for 3 times in 3 patients, the endotracheal intubation by using the LMA CTrach was accomplished in 75 patients. The mean time from insertion of the LMA CTrach to the completion of tracheal intubation was 192 s （range, 156 - 273 s）. Conclusions The LMA CTrach system has the ability to align the LMA outlet with the larynx under direct view, and can increase the success rate of intubation and avoid some unnecessary injuries, giving certain advantages for airway management during cervical spine surgery.
