Comparison of video laryngoscopes for tracheal intubation in ER and ICU - Comparison of video laryngoscopes for tracheal intubation in ER and IC

287 cases were enrolled. First attempt success rate differed significantly among the 4 laryngoscopes (Pentax-Airway Scope, AWS=78%, King VISION, KV=58%, McGrath MAC, McG=78%, and Macintosh laryngoscope, ML=58%, p=0.004). In post hoc analysis, AWS or McG had higher first attempt success rate compared with KV or ML respectively. In non-experts subgroup, first attempt success rate was differed among 4 laryngoscopes (87%, 50% 78% and 46%, p=0.00004) and AWS or McG had significantly higher first attempt success rate compared with KV or ML respectively, but not in experts subgroup (67% vs 67% vs 78% vs 78%, p=0.556). After adjusting for indications of tracheal intubation, limited mouth opening, restricted neck mobilization, bloods/secretion/vomitus in airway, expert/non-expert, use of AWS (odds ratio 3.422, 95% confidence interval 1.551-7.550, p=0.002) and McG (3.758, 1.640-8.612, p=0.002) were associated with increased odds of first attempt success.
