Use of the Airtraq laryngoscope in a model of difficult intubation by prehospital providers not previously trained in laryngoscopy.

This study evaluated the ability of prehospital providers who had no previous training in intubation, to use an Airtraq laryngoscope to intubate a manikin model of a Cormack and Lehane grade III/IV view. Volunteers attending the Australian College of Ambulance Professionals conference, Adelaide, in November 2006 received approximately 5 min of Airtraq training. First-time intubation success rate was 26/33 (79%) (95% CI 61'91%); oesophageal intubation rate was 0/33 (0%) (95% CI 0'11%); median time to intubation was 17 s (IQR 10'25 s (range 5'30 s)); and median subject-rated difficulty of use score was 21 out of a maximum of 100 (IQR 7.5'35.5 (range 1'65)). Pre-hospital providers without previous laryngoscopy training achieved high first-time intubation success rates when managing a model of a grade III/IV difficult intubation with an Airtraq laryngoscope. Users evaluated it as easy to use and achieved intubation within an acceptable breath-to-breath interval.
