The development of less expensive, smaller, and more reliable video cameras has revolutionized the design of laryngoscopes and the process of endotracheal intubation. The term video laryngoscopy defines a broad range of devices, distinct from fiberoptic bronchoscopes, in which a video camera is used in place of line-of-sight visualization to accomplish endotracheal intubation. Over a dozen laryngoscopes are marketed currently. Each model of video laryngoscope has its own unique strengths, weaknesses, and best applications. For the purposes of this review, video laryngoscopes are grouped into 3 different designs: stylets, guide channels, and video modifications of the traditional (usually Macintosh) laryngoscope blades.
