Airway securing through the placement of an endotracheal tube continues to be the definitive and the global standard management. The successful first attempt is aimed to avoid the consequences of multiple intubation trials as bleeding, tissue swelling, and airway contamination from gastric content that led to considerable morbidity and mortality. Visualization of the larynx and the glottic opening is the key to first-pass success requiring long-term training and availability of specific equipment concerned to that. For confirmation of the position endotracheal tube or its displacement, various clinical and equipment aids to that which are not valid or limited in different scenarios. Video laryngoscopes (VL) have been proposed to improve laryngeal visualization, hence a higher first-pass success rate accomplished. Despite that, there are limitations of video laryngoscope use in different circumstances that requiring adding of other aids to facilitate endotracheal intubation.

Video laryngoscopes (VL) have been proposed to improve laryngeal visualization, hence a higher first-pass success rate accomplished. Despite that, there are limitations of video laryngoscope use in different circumstances that requiring adding of other aids to facilitate endotracheal intubation.

The proposal of this study is to assess the feasibility and the impact of infrared/near-infrared (IRD) light on the performance of video-laryngoscopy and reduction of the time needed for endotracheal intubation and increase the credibility of the device.

Data-collection will be started after induction of the anesthesia and ended at the confirmation of endotracheal tube position
