Laryngoscopy skill performance levels change after one month without practice, with worse consistency for C-MAC and AP Advance, according to a study published online Aug 17 in Anaesthesia.

UK researchers 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.

According to results, there was 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.
