Two consecutive, randomised, cross-over trials compared intubation success rates in third-year paramedic students and experienced prehospital practitioners using the Airtraq or a Macintosh laryngoscope with flexible stylet in a manikin model of a Cormack and Lehane grade III/IV laryngoscopic view. First-time intubation rates for the Macintosh and Airtraq for students were 0/23 (0%) vs 10/23 (44%) (44% difference, 95% CI 26-63%, p < 0.001) and for experienced laryngoscopists were 14/56 (25%) vs 47/56 (84%) (59% difference, 95% CI 42-72%, p < 0.0001), respectively. First-time oesophageal intubation rates for students were 15/23 (65%) vs 3/23 (13%) (-52% difference, 95% CI -25 to -72%, p < 0.001) and for experienced practitioners 9/56 (16%) vs 0/56 (0%) (-16% difference, 95% CI -9 to -28%, p = 0.0014). Student paramedics and experienced prehospital laryngoscopists managing a manikin model of a grade III/IV view had increased first-time intubation rates and had lower rates of oesophageal intubation with the Airtraq compared with a standard laryngoscope.
两项连续的随机交叉试验比较了三年级护理人员学生和经验丰富的院前从业者在模拟Cormack和Lehane III/IV级喉镜视野的人体模型中使用Airtraq喉镜或带有可弯曲管芯的Macintosh喉镜时的插管成功率。学生使用Macintosh喉镜和Airtraq喉镜的首次插管率分别为0/23（0%）和10/23（44%）（差异44%，95%CI 26 - 63%，p < 0.001），经验丰富的喉镜检查者的首次插管率分别为14/56（25%）和47/56（84%）（差异59%，95%CI 42 - 72%，p < 0.0001）。学生的首次食管插管率分别为15/23（65%）和3/23（13%）（差异-52%，95%CI -25至-72%，p < 0.001），经验丰富的从业者的首次食管插管率分别为9/56（16%）和0/56（0%）（差异-16%，95%CI -9至-28%，p = 0.0014）。与标准喉镜相比，处理III/IV级视野人体模型的护理人员学生和经验丰富的院前喉镜检查者使用Airtraq喉镜时首次插管率更高，食管插管率更低。
