Brief summary
Videolaryngoscopy is a simple and effective alternative to direct laryngoscopy. To our knowledge, there are no clinical studies on patients evaluating reusable metal and single-use videolaryngoscopic blades. A total of 180 adult patients of both genders were included in this randomized controlled clinical trial. We compared C-MAC S, C-MAC, D-BLADE and D-BLADE S videolaryngoscopic blades using seven point intubation difficulty scores (IDS) as our primary outcome measure. Patients with predicted difficult airway were excluded. We recorded success rate, time to optimal glottic view, time to tube placement, total time to intubation, POGO score and seven point IDS. Failure of the procedure was declared if intubation was not successful after 120 seconds or if SaO2 dropped <90%. Our study has shown that C-MAC blade provides better results in terms of the total time used to complete the intubation, better view of the glottis and intubation difficulty in comparison to disposable C-MAC S blade, without any differences in overall success or incidence of complications. Regarding the difference between D-BLADE and D-BLADE S, our results have shown that the use of both blades achieves similar times to successful intubation, overall success rate and complication incidence, with a statistical difference in respect of quality of laryngeal view and intubation difficulty in favour of the reusable blade. Our results suggest that there is more difference between C-MAC and C-MAC S than D-BLADE and D-BLADE S blades, which could be the result of differences in the blade design.
