Is KingVision videolaryngoscope with a bougie really an effective solution for emergency intubation?

Excerpt

The recent article of See et al. [1] introducing the bougie-in-channel intubation technique shows that the use of a KingVision videolaryngoscope with a bougie can result in high first-attempt success in manikin and human trials. However, their manikin and human studies were small single-arm observable studies without a control design. Thus, an important question that remains unanswered in this study is whether this new technique really performs better than other methods for emergency intubation. Other than first-attempt success, moreover, the time required for intubation is also a special concern for critically ill patients requiring emergency intubation, especially patients at risk of hypoxia and aspiration [2]. In their manikin trial, the use of a 2-min cut-off time for successful intubation is evidently inappropriate. …
