The aim of this study was to compare the performance of the I-Gel airway (IGA) to the King LT laryngotracheal airway (KA) in a simulated tactical scenario. The evaluation was carried out by assessing the time to successful tube placement on a manikin. Participants were also videomonitored to assess their height exposure above the protection barrier. Finally, participants were questioned on which device they preferred with results favouring i-gel.

Study to determine if a bougie could be successfully placed in a cadaver by emergency medicine providers using four supraglottic airway devices: LMA Supreme®, i-gel®, LMA® and KingLT®. Time to placement, confidence in the procedure and correct placement via direct laryngoscopy post-removal were recorded. No great significant differences in most areas, however i-gel® was much quicker than KingLT® to successfully insert, and generally outperformed it. LMA Supreme® and i-gel® considered the better devices for such a procedure, although the authors concede that using a cadaver did inhibit the study.
