Intubation Success and Glottis Visualization With King Vision Video Laryngoscope as Compared to Conventional Laryngoscopes in Children < 1 Years: A Randomized Control Trial

Securing the airway by tracheal intubation is one of the most critical steps during administration of general anesthesia to infants. Failure or a delay in tracheal intubation leads to severe hypoxic insult to infants as the oxygen consumption is high in them when compared to adults.Smaller caliber of the pediatric airway, relatively large tongue, anteriorly located larynx, floppy and relatively large epiglottis predispose young children to airway obstruction during Anaesthesia. In addition, the large occiput of the infant places the head and neck in the flexed position when the patient is placed recumbent, further exacerbating airway obstruction

Direct laryngoscopy requires a direct line of sight for proper glottis visualization which is achieved by proper alignment of airway axes (oral-pharyngeal-laryngeal). These manipulations can lead to significant hemodynamic disturbance, cervical instability, injury to oral and pharyngeal tissues and dental damage. In contrast to direct laryngoscopy, video laryngoscope utilizes indirect laryngoscopy via its camera and helps improve glottic visualization, thereby minimizing complications

New age videolaryngoscopes with their unique design provide better glottis visualization without the requirement of proper alignment of oral-pharyngeal-laryngeal axes, thereby minimizing the complications associated with excessive manipulation and hence provide a decent edge over the conventional indirect laryngoscopes routinely used. With the above mentioned advantages these videolaryngoscopes can be efficiently used in both elective as well as emergencysettings in infants for intubation The investigators in this study will be evaluating the efficacy of King vision video laryngoscope when compared to the conventional laryngoscopes in routine use for infants.
