State of the art: Video and optical laryngoscopy

Rapid expansion of video-laryngoscopes into all spheres of routine and emergency practice has been the most dramatic development in airway management over the past few years. Today, the market offers a plethora of devices from manufacturers around the globe. Video and optical laryngoscopes require adaptation of skills learnt in normal intubation. Decisions regarding the ideal device to purchase or for use in specific cases are becoming increasingly common, and familiarity with one type does not guarantee effective use of another. In this review, I examine the evidence underlying the use of video- and optical laryngoscopy, elucidate a system of classification, compare and comment on the different types and models available. Drawing on real case photographs and videos, I will demonstrate the modifications in technique required for mastery.
