The main objectives of this study were to assess the ease of the use of the TrachView videoscope and to compare it with direct laryngoscopy (DL) for teaching orotracheal intubation to emergency medicine (EM) medical students. Thirty-seven EM students with no earlier intubation experience were asked to intubate a manikin's trachea using DL alone and DL in combination with the TrachView. This investigation involved a randomized, cross-over study design and each trainee received a 10-min demonstration with each technique before the beginning of the study. The Percentage Of Glottic Opening (POGO) scores (%) were recorded and the ease of use of the device for intubation was evaluated by each student using a three-point rating scale. The median POGO score for the DL alone was 25% (range, 0-100%). However, the POGO score improved to 90% (range, 15-100%) with the addition of the TrachView device (P<0.001). The TrachView was considered easy to use by a majority of the EM students and improved visualization of the vocal cords compared with DL alone. The time to achieve successful intubation of the manikin's trachea was shorter when the TrachView was used as an adjunct to DL.
