BackgroundThe Storz C-MAC videolaryngoscope has been found to facilitate endotracheal intubation and to be easy to use by novice users. However, it has never been studied in those who will probably use it most, anesthetists and anesthetic nurses. The aim of the present study was to identify the number of attempts needed before the participants were able to intubate 2 consecutive patients within 30 seconds.MethodsFollowing a didactic session, 22 anesthetists and 21 anesthetic nurses were included in the study and attempted to intubate 184 patients with predicted easy laryngoscopy scheduled to undergo elective surgery. The number of attempts before achieving 2 consecutive successful intubations and time to intubation were recorded for both groups of participants. Perception of ease of use for the device was also recorded.ResultsOverall, anesthetic nurses required more attempts before achieving 2 consecutive successful intubations (5.9 +/- 3.24 vs 2.73+/- 1.67, p < 0.0005). They also had significantly more failures until 2 consecutive successful intubations were achieved, compared to anesthetists (4.1 +/- 2.8 vs 1.32 +/- 1.25, p < 0.0005). A significantly higher percentage of anesthetic nurses required more than 3 attempts before achieving 2 consecutive intubations (75% vs 36%, p = 0.016). Regarding the intubation time, no significant differences were recorded between specialties. Anesthetic nurses assessed the C-MAC as easier to use than anesthetists did.ConclusionsThis is the first clinical study assessing the use of the C-MAC videolaryngoscope by inexperienced anesthetists and anesthetic nurses indicating that it is easy to learn and to use in their hands.
