Worse consistency seen for C-MAC and A.P. Advance versus Macintosh and Airtraq
MONDAY, Aug. 22, 2016 (HealthDay News) — Laryngoscopy skill performance levels change after one month without practice, with worse consistency for C-MAC and A.P. Advance, according to a study published online Aug. 17 in Anaesthesia.
I. Hunter, from the Royal United Hospital in Bath in the United Kingdom, and colleagues compared the time taken to intubate the trachea of a manikin by novice medical students immediately after training and after one month with no intervening practice. The authors conducted a two-period, four-group cross-over trial to compare the Macintosh, Venner A.P. Advance with difficult airway blade, C-MAC with D-Blade, and Airtraq with wireless video-viewer.
The researchers observed no significant difference in median intubation time using the videolaryngoscopes versus the Macintosh (30 seconds) after training. Intubation time was longer using the C-MAC and A.P. Advance versus the Macintosh (41 and 30 seconds, respectively, versus 27 seconds) one month later; there was no difference for the Airtraq (27 seconds) versus the Macintosh. For each laryngoscope, skill acquisition after a brief period of learning and practice was equal; however, after one month without practice, performance levels differed. In particular, worse consistency was seen for C-MAC and A.P. Advance versus Macintosh and Airtraq.
“While the clinical significance of this is doubtful, we believe that reliable and consistent performance at laryngoscopy is desirable; for the devices that we tested, this requires regular practice,” the authors write.
