We analysed the results of the first phase of the Zurich Unexpected Difficult Airway course. Two hundred and twenty-eight staff members performed a total of 2712 standardised airway rescue procedures with four airway devices: SensaScope™, LMA Fastrach™, Laryngeal Tube and needle cricothyrodotomy. Four consecutive attempts were performed using each device. We analysed the success rate and the time needed for successful completion for each attempt and device. The success rates and mean (SD) completion times for all participants were 96.2% and 30.2 (15.3) s for the SensaScope, 88.1% and 40.4 (17.2) s for the LMA Fastrach, 99.0% and 12.1 (10.6) s for the Laryngeal Tube and 99.0% and 12.3 (6.1) s for needle cricothyroidotomy. The learning curves resulting from the four consecutive attempts with each device showed a clear pattern of improvement. This institutional airway training course represents a promising method to improve the capability of practitioners to cope with unexpected difficult airway situations.
我们分析了苏黎世意外困难气道课程第一阶段的结果。228 名工作人员使用 4 种气道设备（SensaScope™、LMA Fastrach™、Laryngeal Tube 和针型环甲膜切开术）总共进行了 2712 次标准化气道抢救程序。每个设备连续进行了 4 次尝试。我们分析了每次尝试和设备的成功率以及完成所需的时间。所有参与者的成功率和平均（SD）完成时间分别为 SensaScope 为 96.2%和 30.2（15.3）s，LMA Fastrach 为 88.1%和 40.4（17.2）s，Laryngeal Tube 为 99.0%和 12.1（10.6）s，针型环甲膜切开术为 99.0%和 12.3（6.1）s。每个设备的 4 次连续尝试的学习曲线显示出明显的改进模式。这种机构气道培训课程代表了一种有前途的方法，可以提高从业者应对意外困难气道情况的能力。
