“…The LT and IT were shorter in our study than in previous reports regarding the use of DL, KV and AT, which is likely due to the short time gap between the training and evaluation sessions [2, 11, 20]. The duration of demonstration was the same as reported by Maharaj et al, although this time was 10 min longer than in the Pieters study [2, 11].…”

BackgroundDirect laryngoscopy remains the gold standard for endotracheal intubation and is preferred by experienced operators. However, an increasing number of reports currently support videolaryngoscopy, particularly for novice users. The widespread use of videolaryngoscopy may be limited due to financial limitations, especially in low-income countries. Therefore, affordable single-use scopes are now becoming increasingly popular. We sought to compare these new scopes with direct laryngoscopes and the previously tested videolaryngoscopes in mannequins by novices.MethodsFifty medical students were recruited to serve as novice users. Following brief, standardized training, students were asked to execute endotracheal intubation with each of the devices, including the Airtraq®, a custom-made videolaryngoscope, the King Vision®, the Macintosh laryngoscope and the VividTrac®, on an airway trainer (Laerdal Airway Management Trainer®) in normal and difficult airway scenarios. We evaluated the time to and the proportion of successful intubation, the best view of the glottis, esophageal intubation, dental trauma and user satisfaction.ResultsWe observed no differences in esophageal intubation. However, intubation-related times, the view of the glottis and operator satisfaction were significantly better throughout the study with the commercial videolaryngoscopes. In comparison, the custom-made videolaryngoscope performance proved to be similar to that of the Macintosh laryngoscope. The VividTrac® performance was similar (P > 0.05) or significantly better than that of the King Vision® in both scenarios.ConclusionsBased upon our results, the Airtraq®, King Vision® and VividTrac® were superior to the Macintosh laryngscope in both normal and difficult airway scencarios for novice users. In particular, our study is the first to report that the VividTrac® shows promise for further clinical evaluation.

“…It has a hyperacute, angled blade, similar to the GlideScope (Verathon Medical, Bothell, WA) device, which uses an indirect, nondisplacing intubating technique. Recently, several studies have evaluated its use, compared both with DL and with other VL devices, [16][17][18][19] again with mixed results. We identified poor intubation success using DL (64.9% overall success) during normal quality improvement efforts at a suburban EMS system.…”

“…There are two blade types: one is a channeled blade that permits tracheal tube to be passed through the glottis, and the other is a non-channeled blade which just allows visualization of the glottis, and intubation is facilitated by use of a metal stylet [13].…”
