摘　　要：目的评价Truview EVO2喉镜用于模拟颈项强直患者气管插管的效果。方法择期经口气管插管全麻手术患者100例,静脉麻醉诱导后使用硬质颈托固定其颈部,所有患者随机先后使用Truview EVO2喉镜和Macintosh喉镜显露喉部,并采用后一种喉镜辅助气管插管。记录Cormack-Lehane(C-L)分级,喉部结构显露时间,气管插管完成时间,一次插管成功率等。结果 Truview EVO2喉镜C-L分级显著优于Macintosh喉镜(P<0.05),喉部结构显露时间短于Macintosh喉镜(P<0.05),插管一次成功率显著高于Macintosh喉镜(P<0.05);但两种喉镜的气管插管完成时间差异无统计学意义。结论 Truview EVO2喉镜用于模拟颈项强直患者气管插管效果明显优于Macintosh喉镜,对于颈部活动受限患者具有很好的应用价值。Objective To evaluate the effect of Truview EVO2 laryngoscope in trachea intubation of patients with simulated neck rigidity. Methods One hundred patients, scheduled for elective surgery under general anesthesia requiring orotracheal intubation were enrolled. After intravenous anesthetic induction, a rigid cervical collar was used to simulate the neck rigidity patients. Orotracheal intubation was randomly performed by Truwiew EVO2 and Macintosh laryngoscope in different order. After given the Cormack-Lehane （C-L） grade of laryngeal view, the patient was intubated with the latter laryngoscope. Parameters were recorded, including the laryngeal exposuring and intubation time, success rate for intubation in the first attempt. Results The Truview EVO2 laryngoscope achieved better C-L grade of laryngeal view than Macintosh laryngoscope（P〈0. 05）. The laryngeal exposuring time of Truview EVO2 laryngoscope was shorter than Macintosh laryngoscope（P〈0. 05）, but the intubation time was similar. The success rate for intubation in the first attempt of Truview EVO2 laryngoscope was significantly higher than Macintosh laryngoscope（P 〈0. 05）. Conclusion In patients with simulated neck rigidity, the Truview EVO2 laryngoscope was more feasible and effective than Macintosh laryngoscope in orotracheal intubalion, it is valuable in managing difficult airway for restricted neck movements.
