Abstract

The importance of videolaryngoscopy has recently been recognized in the DAS 2015 guidelines. The gold standard for safe placement of an endotracheal tube is observing its passage between the vocal cords. For direct laryngoscopy (DL), alignment of the oral, pharyngeal, and laryngeal axes is necessary to view the glottis, but line-of-sight visualization may be impossible for some patients secondary to anatomic factors, and due to these limitations, DL may fail. Videoscopy has made inroads into our daily life especially in the field of information technology. Our surgical colleagues have been using video technology since the 1980s but the anesthetists have employed this innovation much later, in the field of airway management. The advent of the video camera chip led to the development of the videolaryngoscope (VL), one that has contributed to the safety of the airway in a variety of situations. Advantages of videolaryngoscopy, disadvantages of videolaryngoscopy, scope of videolaryngoscopes, complications of videolaryngoscopes, and safety of videolaryngoscopes are also covered in this chapter.
