Trial on 84 adults assigned to either laryngoscopy or control groups, with number of attempts to successful insertion and difficulty of insertion the primary outcomes measured. Results suggest that laryngoscopy facilitates i-gel insertion by novice doctors.

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.
