Abstract

We compared the time taken to perform cricothyroidotomy on a manikin to that on a medium fidelity simulator, to assess the effect of psychological stress and time pressure on performance. Seventy anaesthetists participated in this randomised cross-over study. Fifty-four (77%) anaesthetists took longer on the simulator, with the mean (SD) time taken to perform the procedure on the manikin and simulator 34 (18) and 48 (11) s, respectively (p < 0.001). Anaesthetists with more experience performed the procedure more quickly on both manikin and simulator. We conclude that psychological stress and time pressure in real-life scenarios can affect the performance of cricothyroidotomy.

摘要

我们比较了在人体模型和中等逼真度模拟器上进行环甲膜切开术所需的时间，以评估心理压力和时间压力对操作的影响。70名麻醉医生参与了这项随机交叉研究。54名（77%）麻醉医生在模拟器上花费的时间更长，在人体模型和模拟器上执行该操作的平均（标准差）时间分别为34（18）秒和48（11）秒（p<0.001）。经验更丰富的麻醉医生在人体模型和模拟器上执行该操作的速度都更快。我们得出结论，现实场景中的心理压力和时间压力会影响环甲膜切开术的操作表现。
