There is little evidence guiding equipment handling during emergency endotracheal intubations (EEI). Available evidence and current practice are either outdated, anecdotal or focused on difficult-not emergency-intubation. In this study, we describe and evaluate our equipment handling unit: the AIR-BOX.
This is a proof-of-concept, prospective, randomised simulation trial. A convenience sample of 50 airway course participants voluntarily underwent randomisation: 21 to the AIR-BOX group, 14 to the intubation box group, and 15 to the crash cart group. The volunteers were asked to intubate a manikin using the equipment from the storage unit of their randomisation. Outcome measures included time-to-readiness, time-to-intubation, first-pass success, and subjective operator experience.
The mean time-to-readiness was 67.2 s with the AIR-BOX, 84.6 s with the intubation box, and 115 s with the crash cart. The mean time-to-intubation was 105 s with the AIR-BOX, 127 s with the intubation box and 167 s with the crash cart. A statistically significant difference was achieved between the AIR-BOX and the crash cart. No statistically significant difference was found between the three groups with regard to first-pass success or the time between intubation readiness and intubation.
This study supports the AIR-BOX as a viable tool that can improve and simplify access to emergency intubating equipment. It also opens doors for multiple future innovations that can positively impact equipment handling practices. Future studies can focus on assessing whether applying the AIR-BOX will yield a clinically significant impact on patient outcomes.
在紧急气管插管(EEI)过程中,几乎没有证据指导设备操作。现有证据和当前实践要么过时、基于传闻,要么侧重于困难插管(而非紧急插管)。在本研究中,我们描述并评估了我们的设备操作单元:AIR - BOX。
这是一项概念验证、前瞻性、随机模拟试验。50名气道课程参与者的便利样本自愿接受随机分组:21人分到AIR - BOX组,14人分到插管箱组,15人分到急救推车组。要求志愿者使用随机分组储存单元中的设备对人体模型进行插管。结果指标包括准备就绪时间、插管时间、首次通过成功率和操作者主观体验。
使用AIR - BOX时,平均准备就绪时间为67.2秒,使用插管箱时为84.6秒,使用急救推车时为115秒。使用AIR - BOX时,平均插管时间为105秒,使用插管箱时为127秒,使用急救推车时为167秒。AIR - BOX组和急救推车组之间存在统计学显著差异。在首次通过成功率或插管准备就绪到插管之间的时间方面,三组之间未发现统计学显著差异。
本研究支持AIR - BOX作为一种可行的工具,可改善并简化紧急插管设备的获取。它还为未来多种可能对设备操作实践产生积极影响的创新打开了大门。未来的研究可以集中于评估应用AIR - BOX是否会对患者结局产生临床显著影响。
