“…Despite promising results, the availability of VLs in clinical practice is still considerably restricted, reportedly due to costs [6]. The VT and the ID are affordable and relatively new devices with limited but promising data reported in the literature [6, 8, 9]. …”

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.

“…However, no study has been performed in super obese patient population 19–21. Cierniak et al in their study assessed technical properties of video intubating devices, which showed that there could be significant differences between them regarding the clarity, focus and image quality 8. As this was a manikin study, it is difficult to extrapolate the results of such studies into real patients.…”

“…Videolaryngoscopes use modern video camera technology, which varies between different devices. This can result in a different image clarity and quality of the glottic view 8. Despite continuous development of videolaryngoscopes, some important questions remain unanswered, eg, the limitations of these devices in specific circumstances and their comparative performance 9…”

Videolaryngoscopes improve the view of the entry to the larynx in morbidly obese patients. Super obesity is one of the risk factors for difficult mask ventilation as well as difficult intubation. Super obese patients should be intubated awake either with a fiber-optic scope or with a videolaryngoscope. The glottic view during video-intubation in super obese patients using different devices was compared. The McGrath MAC (MGM) was used in all patients and then compared to the King Vision (KV) in three patients, the APA videolaryngoscope in two patients and the Airtraq Avant with a video camera in four patients. The pictures were of the same patient for two used devices. All obtained images were analyzed using the Percentage of Glottic Opening (POGO) scale. The POGO score for the MGM was better than for the KV and the APA but comparable to the Airtraq device. The images were processed electronically, and the best view of the laryngeal inlet that was obtained by the evaluated devices in the same patient was superimposed onto the other one and then compared.

“…Clinical studies have compared the display quality between different VL; taking into account light intensity, contrast between anatomical structures and view field [20]; finding clinical and design advantages in favor of CMAC that could explain the high efficiency in patients with predictors of a difficult airway [21].…”
