title: Optimising tracheal intubation success rate using the Airtraq laryngoscope.
abstract: In this study we have used a video-recording, retrospective analysis technique to evaluate the influence of the Airtraq laryngoscope manipulations and the resulting changes in position of the glottic opening and inter-arytenoids cleft, on the success rate of tracheal intubation. The video recordings of the internal views of 109 tracheal intubation attempts, in 50 anaesthetised patients were analysed. We demonstrated that successful tracheal intubation using the Airtraq laryngoscope require the glottic opening to be centred in the view, and positioning the inter-arytenoid cleft medially below the horizontal line in the centre of the view. We also demonstrated that repositioning of the Airtraq laryngoscope following a failed tracheal intubation attempt required the performance of a standard series of manoeuvres.
