This study compared the use of the i-gel®, LMA Supreme®, LMA Unique® and LMA ProSeal® supraglottic airways and bag-valve mask ventilation. 267 third-year medical students were given standardised training before using all devices in random order on an airway training manikin. The number of attempts needed to secure the device, time to successful ventilation, tidal volume, ease of use and incidence of gastric inflation were all recorded. After 12 months, participants used the devices again without further training. In both assessments, the i-gel® and the Supreme were the most likely to be inserted successfully on the first attempt. These devices were rated as the easiest to use. The i-gel® and bag-valve mask had the quickest time to successful ventilation, however the rate of gastric inflation was much higher with the bag-valve mask.
