The Airtraq laryngoscope is a novel intubation device that may possess advantages over conventional direct laryngoscopes for use by personnel that are infrequently required to perform tracheal intubation. We conducted a prospective study in 20 medical residents with little prior airway management experience. After brief didactic instruction, each participant took turns performing laryngoscopy and intubation using the Macintosh (Welch Allyn, Welch Allyn, NY) and Airtraq (Prodol Ltd. Vizcaya, Spain) devices, in 3 laryngoscopy scenarios in a Laerdal Intubation Trainer (Laerdal, Stavanger, Norway) and 1 scenario in a Laerdal SimMan manikin (Laerdal, Kent, UK). They then performed tracheal intubation of the normal airway a second time to characterize the learning curve. In all scenarios tested, the Airtraq decreased the duration of intubation attempts, reduced the number of optimization maneuvers required, and reduced the potential for dental trauma. The residents found the Airtraq easier to use in all scenarios compared with the Macintosh laryngoscope. The Airtraq may constitute a superior device for use by personnel infrequently required to perform tracheal intubation.
Airtraq喉镜是一种新型插管设备，对于不常进行气管插管的人员而言，它可能比传统直接喉镜具有优势。我们对20名几乎没有气道管理经验的住院医师进行了一项前瞻性研究。经过简短的理论指导后，每位参与者轮流使用Macintosh（韦尔奇·阿林公司，纽约州韦尔奇·阿林）和Airtraq（普罗多尔有限公司，西班牙比斯开湾）设备，在挪威斯塔万格的Laerdal插管训练器中的3种喉镜检查场景以及英国肯特郡的Laerdal SimMan人体模型中的1种场景下进行喉镜检查和插管。然后，他们再次对正常气道进行气管插管，以描绘学习曲线。在所有测试场景中，Airtraq缩短了插管尝试的持续时间，减少了所需的优化操作次数，并降低了牙齿损伤的可能性。与Macintosh喉镜相比，住院医师发现Airtraq在所有场景中都更易于使用。对于不常进行气管插管的人员而言，Airtraq可能是一种更优越的设备。
