“…A study performed showed that it is necessary to constantly practice airway management methods including performing endotracheal intubation [41]. It is particularly important to learn how to use multiple laryngoscopes, as this can be useful in unconventional situations that require the modification of the technique, equipment, or body position [33].…”

The aim of the study was to test the hypothesis that the results obtained with three different types of video laryngoscopes (UESCOPE VL-400, I-View, Non-Channeled Aitraq) with and without an endotracheal stylet should be better than the results obtained with a Macintosh laryngoscope in a simulated out-of-hospital scenario by a person without clinical experience. Primary outcome measures were the time taken to successfully achieve tracheal intubation (TI). Secondary outcomes included the grade of glottic view (Cormack and Lehane grades 1–4), the incidence of successful TI, the number of audible dental clicks indicating potential dental damage, the level of effort required to perform TI, and the operator’s comfort during the procedure. The time required to achieve tracheal intubation successfully was significantly longer with the Macintosh laryngoscope and Airtraq than with the other video laryngoscopes. The use of the stylet significantly reduced the time required for tracheal intubation with the Macintosh laryngoscope (21.8 sec. vs. 24.0 sec., p = 0.026), UESCOPE VL 400 (18.1 sec. vs. 23.4 sec., p = 0.013), and Airtraq (22.7 sec. vs. 34.5 sec., p < 0.001). There were no significant differences in intubation time when using the I-View with or without stylets. No differences were observed in the Cormack–Lehane grading. The success rate of intubation was 100% for the Macintosh and I-View laryngoscopes used with or without stylets and for the UESCOPE VL 400 and Airtraq laryngoscopes used with stylets. Without stylets, the success rate of intubation was 96.6% for the UESCOPE VL 400 and 86.6% for the Airtraq. There were no significant differences in the risk of dental damage between the Macintosh, UESCOPE VL 400, I-View, and Airtraq laryngoscopes, regardless of the use of stylets (without and with stylets). The use of stylets significantly reduced dental damage only for the Airtraq laryngoscope: 8 (26.6%) vs. 2 (6.6%). Statistically significant differences in perceived exertion were observed between the mentioned laryngoscopes, both with and without stylets. However, there were no differences in the comfort of use between the laryngoscopes, regardless of the use of stylets (without and with stylets. The use of stylets led to better comfort in the case of the Macintosh (2.5 vs. 3, p = 0.043) and UESCOPE VL 400 (2 vs. 3, p = 0.008) laryngoscopes. In our study, the I-View and UESCOPE VL-400 video laryngoscopes provided better intubation results than the Macintosh laryngoscope in terms of time needed to intubate, glottis visibility, and reduction in dental damage. The use of the stylet did not significantly improve the intubation results compared to the results obtained in direct laryngoscopy. Due to the small study group and the manikin model, additional studies should be performed on a larger study group.

The aim of the study was to evaluate the laryngoscopes Macintosh, Miller, McCoy, Intubrite, VieScope and I-View in simulated out-of-hospital conditions when used by people without clinical experience, and to choose the one that, in the case of failure of the first intubation (FI), gives the highest probability of successful second (SI) or third (TI). For FI, the highest success rate (HSR) was observed for I-View and the lowest (LSR) for Macintosh (90% vs. 60%; p < 0.001); for SI, HSR was observed for I-View and LSR for Miller (95% vs. 66,7%; p < 0001); and for TI, HSR was observed for I-View and LSR for Miller, McCoy and VieScope (98.33% vs. 70%; p < 0.001). A significant shortening of intubation time between FI and TI was observed for Macintosh (38.95 (IQR: 30.1–47.025) vs. 32.4 (IQR: 29–39.175), p = 0.0132), McCoy (39.3 (IQR: 31.1–48.15) vs. 28.75 (IQR: 26.475–35.7), p < 0.001), Intubrite (26.4 (IQR: 21.4–32.3) vs. 20.7 (IQR: 18.3–24.45), p < 0.001), and I-View (21 (IQR: 17.375–25.1) vs. 18 (IQR: 15.95–20.5), p < 0.001). According to the respondents, the easiest laryngoscopes to use were I-View and Intubrite, while the most difficult were Miller and VieScope. The study shows that I-View and Intubrite are the most useful devices, combining high efficiency with a statistically significant reduction in time between successive attempts.

Introduction: Airway management in pre-hospital settings is often challenging and difficult to perform. This is particularly true during tracheal intubation of entrapped patients with difficult airway access. There are various airway adjuncts available in the current practice. Their aim is to facilitate tracheal intubation. One of the recently introduced devices is the flexible tip bougie. The aim of this study was to evaluate the flexible tip bougie for intubation in a simulated condition of an entrapped trauma patient with simultaneous cervical spine immobilisation. Methods: An intubation manikin with the cervical collar on was placed on and secured to the driver’s seat of a passenger car. The car was then positioned on its left side. The first attempt success rate as well as the intubation and successful ventilation time were recorded. The ease of use by the operator and user-friendliness were also assessed. Results: The standard gum elastic bougie required the shortest mean intubation to successful ventilation time, 38.4 s (±9.6) vs. 41.4 s (±6.8), p = 0.46. The first attempt success rate was higher in the standard gum elastic bougie group, 92% vs. 88%, p = 0.04. There were no failed intubations when the standard gum elastic bougie was used. The flexible tip bougie was found to be more difficult to use and less user-friendly, 7.6 (±1.5) vs. 5.8 (±2.9), p = 0.02. Conclusions: The standard gum elastic bougie was superior in terms of the first attempt success and the time required for intubation and successful ventilation. Moreover, it was found to be easier to use and more user-friendly.
