Studies indicate that the skills needed to use video laryngoscope systems are easily learned by healthcare providers. This study compared several video laryngoscopic (VL) systems and a direct laryngoscope (DL) view when used by medical residents practicing intubation on cadavers. The video devices used included the Storz Medi Pack Mobile Imaging System™, the Storz CMAC® VL System and the GlideScope®.
After Institutional Review Board (IRB) approval, University of Nebraska Medical Center, Department of Emergency Medicine (UNMC EM) residents were recruited and given a brief pre-study informational period. The cadavers were lightly embalmed. The study subjects were asked to perform intubations on two cadavers using both DL and VL while using the three different VL systems. Procedural data was recorded for each attempt and pre and post experience perceptions were collected.
N=14. All subjects reported their varied previous intubation experience. The average airway score using DL: for the Storz VL was 1.54 (SD = 0.576) and for the C-MAC was 1.46 (SD = 0.637). Success in intubation of the standard airway using DL was 93% versus a 100% success rate when intubating with indirect VL visualization.
Based on our data, we believe that the incorporation of VL into cadaver airway management training provided an improved learning environment for the study residents. In our study, the resident subjects were 93% successful with DL intubation even though 50% had less than 30 intubations. As well, there was a 100% success rate when intubating with indirect VL visualization. In conclusion, the researchers believe this cadaver model incorporated with VL is a powerful tool which may help improve the overall learning curve for orotracheal intubation.
研究表明，医疗保健人员很容易学会使用视频喉镜系统所需的技能。本研究比较了几种视频喉镜（VL）系统和直接喉镜（DL）在医学住院医师对尸体进行插管操作时的视野情况。所使用的视频设备包括史托斯移动成像系统™、史托斯CMAC®VL系统和GlideScope®。
经机构审查委员会（IRB）批准后，招募了内布拉斯加大学医学中心急诊医学系（UNMC EM）的住院医师，并在研究前进行了简短的信息告知期。对尸体进行轻度防腐处理。要求研究对象使用DL和VL以及三种不同的VL系统对两具尸体进行插管操作。记录每次尝试的操作数据，并收集操作前后的感受。
N = 14。所有受试者均报告了他们之前不同的插管经验。使用DL时的平均气道评分：史托斯VL为1.54（标准差= 0.576），C-MAC为1.46（标准差= 0.637）。使用DL对标准气道进行插管的成功率为93%，而使用间接VL可视化插管时成功率为100%。
基于我们的数据，我们认为将VL纳入尸体气道管理培训为研究住院医师提供了更好的学习环境。在我们的研究中，即使50% 的住院医师插管次数少于30次，使用DL插管的成功率仍为93%。此外，使用间接VL可视化插管的成功率为100%。总之，研究人员认为这种结合了VL的尸体模型是一种强大的工具，可能有助于改善经口气管插管的整体学习曲线。
