Abstract: The emergence of videolaryngoscopy has transformed airway management, being widely adopted for tracheal intubation, and enhancing glottic visualization, especially in complex scenarios. Continuous research is crucial to evaluate the efficacy of various designs. This study aims at evaluating the usability and safety of videolaryngoscopes in novice intubation simulations. This study compares the impact of LANJA, UE, and VDO video laryngoscopes on simulated endotracheal intubation by beginners. This non-randomized concurrent controlled simulation study involved 29 medical student volunteers with no prior endotracheal intubation experience. Following theoretical training by experienced anesthesiologists, participants watched intubation demonstration videos and engaged in hands-on practice. Using LANJA, UE, and VDO video laryngoscopes in random order, participants performed endotracheal intubation on a simulated airway mannequin. Observers recorded intubation procedure videos, analyzing intubation time, success rate, and laryngoscope exposure grading. Significant differences were observed in the time required for glottic exposure with the 3 laryngoscopes (intubation visualization time; LANJA: 5.47 ± 2.84; UE: 9.29 ± 2.88; VDO: 8.97 ± 2.99, P = .001). The endotracheal tube placement time (visualization and fixation time) did not differ significantly among the laryngoscopes (LANJA: 25.21 ± 7.35; UE: 25.04 ± 7.75; VDO: 27.66 ± 3.80, P = .31). Overall intubation success rates varied significantly among the 3 laryngoscopes (LANJA: 89.5%, UE: 78.9%, VDO: 63.2%, P = .002); within Cormack-Lehane grades, LANJA showed the highest percentage in Grade I (68.8%). LANJA video laryngoscope demonstrated a higher success rate in guiding endotracheal intubation, reducing glottic exposure time, and is suitable for use by beginners.
