Clinically Preferred Videolaryngoscopes in Airway Management: An Updated Systematic Review

Abstract

Videolaryngoscopes (VLs) have emerged as a safety net offering several advantages over direct laryngoscopy (DL). The aim of this study is to expand on our previous study conducted in 2016, to deduce which VL is most preferred by clinicians and to highlight any changes that may have occurred over the past 7 years. An extensive systematic literature review was performed on Medline, Embase, Web of Science, and Cochrane Central Database of Controlled Studies for articles published between September 2016 and January 2023. This review highlighted similar results to our study in 2016, with the CMAC being the most preferred for non-channelled laryngoscopes, closely followed by the GlideScope. For channelled videolaryngoscopes, the Pentax AWS was the most clinically preferred. This review also highlighted that there are minimal studies that compare the most-used VLs, and thus we suggest that future studies directly compare the most-used and -preferred VLs as well as the specific nature of blades to attain more useful results.

Styletubation versus Laryngoscopy: A New Paradigm for Routine Tracheal Intubation

“…Factors influencing such comparator include design of the device, patient's factors, clinical scenarios, and airway operator's skills and competency. Numerous clinical studies and meta-analyses show the comparison between Macintosh DL and various VL in normal and difficult airway scenarios [86][87][88][89] In our experiences, when either experienced staff or novice trainees applied styletubation, it usually took about 5 s to 10 s (from lip to trachea) to accomplish the trachea intubation in patients with normal airway. Although it can be done in 3 s in an easy airway scenario and 30 s to 60 s for teaching purpose, we regard 10 s of such "time to intubation" be reasonable, easy, smooth, and elegant.…”

“…Factors influencing such a comparator include design of the device, patient's factors, clinical scenarios, and airway operator's skills and competency. Numerous clinical studies and meta-analyses show the comparison between a Macintosh DL and various VLs in normal and difficult airway scenarios [86][87][88][89]. For example, the time to intubation in normal airways with a DL and VL, respectively, are 9 s and 11 s [90] In our experiences, when either experienced staff or novice trainees applied styletubation, it usually took about 5 s to 10 s (from lip to trachea) to accomplish the trachea intubation in patients with normal airways.…”
