Previous reports have shown a high rate of ventilation failure via direct laryngoscopy as compared with the King LT-D airway. This difference is further divergent in the pediatric population. The goal of this study was to compare the difference in efficacy of ventilation by prehospital providers in a simulated environment between direct laryngoscopy and Pedi-King LT-D.
In this study, 37 paramedics were exposed to 2 identical 5-minute clinical scenarios in a simulation center using a pediatric simulation tool. In the first scenario, the provider was given all of the standard laryngoscopy equipment. In the second scenario, they were given access only to the Pedi-King LT-D. A comparison of adequate ventilation time between the scenarios was performed.
A mean improvement of 102 seconds was found when using the Pedi-King airway, with a clinically significant P < 0.0001.
With a significant improvement in ventilation time in these simulated airways, consideration should be made to practice placement of the King Airway Device as first-line airway stabilization. Further live prospective studies would aid in this recommendation.
先前的报告显示，与King LT-D气道相比，直接喉镜检查导致通气失败的发生率较高。这种差异在儿科人群中更为明显。本研究的目的是比较在模拟环境中，院前急救人员使用直接喉镜检查和儿童King LT-D进行通气的效果差异。
在本研究中，37名护理人员在模拟中心使用儿科模拟工具，接触2个相同的5分钟临床场景。在第一个场景中，为急救人员提供所有标准的喉镜检查设备。在第二个场景中，他们只能使用儿童King LT-D。对两个场景之间的充分通气时间进行了比较。
使用儿童King气道时，平均通气时间改善了102秒，具有临床意义的P<0.0001。
在这些模拟气道中通气时间有显著改善，应考虑将King气道装置的放置练习作为一线气道稳定措施。进一步的现场前瞻性研究将有助于这一建议。
