The summary below is from an episode of ERcast: Clinical Perspectives
Videolaryngoscopy is no longer one technique. Hyperangulated blades and Mac-style video blades create different views, require different tube-delivery strategies, and fail in different ways during emergency airway management.
Videolaryngoscopy 2.0 Airway Approach
- Precise VL terminology: “VL” is too vague for modern airway practice; naming hyperangulated VL versus Mac-VL better describes the intubation you actually performed and improves how clinicians communicate about difficult airways.
- Blade geometry matters: The key distinction is blade shape, not the presence of a camera: hyperangulated blades run about 60 to 70 degrees, while Mac-VL keeps standard Macintosh geometry with a very different feel and workflow.
- Different device techniques: Hyperangulated VL generally needs a rigid stylet for tube delivery, whereas Mac-VL is better suited to bougie-assisted intubation and should not be approached with the same hand mechanics.
- Soiled airway advantage: Mac-VL can look past the tongue and still permits a direct view if blood or vomit obscures the screen, a practical rescue advantage we get into in the episode.
- Teaching and backup planning: Mac-VL is useful for teaching direct laryngoscopy while sharing the screen, but neither blade guarantees first-pass or rescue success, so a backup airway plan still has to be explicit.
- Research language problem: Pooling hyperangulated devices and Mac-VL under one “VL” label muddies airway research, because device geometry changes performance, complications, and what success rates really mean.
