The C-MAC comprises a Macintosh blade connected to a video unit. The familiarity of the Macintosh blade, and the ability to use the C-MAC as a direct or indirect laryngoscope, may be advantageous. We wished to compare the C-MAC with Macintosh, Glidescope and Airtraq laryngoscopes in easy and simulated difficult laryngoscopy. Thirty-one experienced anaesthetists performed tracheal intubation in an easy and difficult laryngoscopy scenario. The duration of intubation attempts, success rates, number of intubation attempts and of optimisation manoeuvres, the severity of dental compression, and difficulty of device use were recorded. In easy laryngoscopy, the duration of tracheal intubation attempts were similar with the C-MAC, Macintosh and Airtraq laryngoscopes; the Glidescope performed less well. The C-MAC and Airtraq provided the best glottic views, but the C-MAC was rated as the easiest device to use. In difficult laryngo-scopy the C-MAC demonstrated the shortest tracheal intubation times. The Airtraq provided the best glottic view, with the Macintosh providing the worst view. The C-MAC was the easiest device to use.
C-MAC 包括一个连接到视频单元的 Macintosh 刀片。Macintosh 刀片的熟悉程度，以及可以将 C-MAC 用作直接或间接喉镜的能力，可能是有利的。我们希望在简单和模拟困难的喉镜检查中比较 C-MAC 与 Macintosh、Glidescope 和 Airtraq 喉镜。31 名经验丰富的麻醉师在简单和困难的喉镜检查情况下进行气管插管。记录了插管尝试的持续时间、成功率、插管尝试次数和优化操作次数、牙齿压迫的严重程度以及设备使用的难度。在简单的喉镜检查中，C-MAC、Macintosh 和 Airtraq 喉镜的气管插管尝试持续时间相似；Glidescope 的效果较差。C-MAC 和 Airtraq 提供了最佳的声门视图，但 C-MAC 被评为最容易使用的设备。在困难的喉镜检查中，C-MAC 显示出最短的气管插管时间。Airtraq 提供了最佳的声门视图，而 Macintosh 则提供了最差的视图。C-MAC 是最容易使用的设备。
