Abstract：
UNASSIGNED: Video laryngoscopes are commonly used along with Macintosh and McCoy laryngoscopes for Nasotracheal intubation (NTI). The purpose of this study was to evaluate the performance of McCoy, Macintosh, and Truview laryngoscopes during bougie-aided NTI with respect to intubation time, success rate, and hemodynamic changes during the procedure.
UNASSIGNED: Forty-five American Society of Anesthesiologists (ASA) I-II adult patients, with Mallampati grade 1-4, requiring NTI, were enrolled after taking written informed consent. ASA III/IV, restricted mouth opening, and body mass index >30 were excluded from the study. Patients were randomly allocated to intubate with one of the three laryngoscopes (McCoy, Macintosh, and Truview) and the anesthesiologists were well experienced with all of them. The primary outcome was intubation time and secondary outcomes included first attempt success rate, external laryngeal manipulation, Cormack-Lehane (CL) grade, and hemodynamic responses.
UNASSIGNED: The intubation time of McCoy, Macintosh, and Truview, was 86.87 ± 15.92, 82.87 ± 16.46, and 79.93 ± 14.53 (mean ± standard deviation) seconds, respectively, which is comparable with Truview being the shortest. CL grade 1 was obtained more in the Truview group (53.3%) compared to the other two groups, while CL grade 3 was obtained in 20% each in McCoy and Macintosh groups.
UNASSIGNED: McCoy, Macintosh, and Truview laryngoscopes were comparable in performance during bougie-aided NTI, with Truview having the shortest intubation time and better visualization.

摘要：
■视频喉镜通常与Macintosh和McCoy喉镜一起用于鼻气管插管（NTI）。这项研究的目的是评估麦考伊的表现，Macintosh,和Truview喉镜在Bougie辅助NTI期间的插管时间，成功率,以及手术过程中的血液动力学变化。
■45名美国麻醉医师协会（ASA）I-II成年患者，Mallampati1-4级，需要NTI，在接受书面知情同意书后登记。ASAIII/IV，限制张口,体重指数>30被排除在研究之外。患者被随机分配到用三个喉镜中的一个插管(McCoy，Macintosh,和Truview）和麻醉师对所有这些都很有经验。主要结局是插管时间，次要结局包括首次尝试成功率，喉外部操作，Cormack-Lehane(CL)等级,和血液动力学反应。
■McCoy的插管时间，Macintosh,和Truview,分别为86.87±15.92、82.87±16.46和79.93±14.53（平均值±标准偏差）秒，分别,这与Truview最短的情况相当。与其他两组相比，Truview组获得的CL1级更多(53.3%)，而在McCoy和Macintosh组中，CL3级各占20%。
■麦考伊，Macintosh,和Truview喉镜在Bougie辅助NTI期间的性能相当，Truview具有最短的插管时间和更好的可视化。
