Clinical application of the LMA CTrach in cervical spine surgery / 中国微创外科杂志

ABSTRACT

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.
