In this study the success rate and time duration of standard intubation techniques were compared with two different supraglottic devices. Two different manikins were used for the study and the training effect was studied when the same manikin was repeatedly used. Methods Twenty anaesthesiologists from the Air Ambulance Department used iGEL laryngeal tube LTSII and Macintosh laryngoscopes in two scenarios with either unrestricted scenario A or restricted scenario B access to the cranial end of the manikin. Different manikins were used for ETI and placement of the supraglottic devices. The technique selected by the physicians the success rates and the times to completion were the primary outcomes measured. A secondary outcome of the study was an evaluation of the learning effect of using the same manikin or device several times. Results In scenario A all anaesthesiologists secured an airway using each device within the maximum time limit of 60 seconds. In scenario B all physicians secured the airway on the first attempt with the supraglottic devices and 16 80 successfully performed an ETI with either the Macintosh laryngoscope n 13 65 or with digital technique n 3 15 . It took significantly longer to perform ETI mean time 28.0 sec - 13.0 than to secure an airway with the supraglottic devices iGel mean 12.3 sec - 3.6 LTSII mean 10.6 sec - 3.2 . When comparing the mean time required for the two scenarios for each supraglottic device there was a reduction in time for .
