Abstract:
Whether the difference in video laryngoscope view affects the success of endotracheal intubation in beginners is unknown. In the current study, we aimed to investigate whether the revision of the monitor program in a Macintosh-type video laryngoscope, AceScopeTM, enhances the endotracheal tube intubation skill in novice physicians. Participants with no experience performing tracheal intubation were assigned to the pre- (n=15) and post-program revision (n=16) groups. Each participant performed tracheal intubation twice using the assigned version of the AceScopeTM video laryngoscope on an immobilized airway setting in the manikin. We assessed the intubation success rate, intubation time, frequency of dental injury, numerical rating scale (NRS) of easiness, and the Cormack & Lehane (CL) classification. The intubation success rate did not differ between the pre-program revision (93%) and post-program revision (100%) groups. The median intubation times were not different between pre- (39 seconds) and post- (31 seconds) groups. The frequency of dental injury, the NRS of easiness, and the CL classification were similar between the two groups. The program revision of the AceScopeTM video laryngoscope did not alter the intubation success rate and median intubation time in novice physicians. Improving the video laryngoscope's monitor view does not enhance solely beginners' intubation conditions. J. Med. Invest. 73 : 32-35, February, 2026.
