Authors conducted a specialised search of study databases for eligible randomised controlled trials, setting device insertion time and first-attempt insertion success rate as their primary outcomes. In the 14 RCTs included, i-gel was faster than the majority of other supraglottic airways, with only three others recording shorter insertion times. Authors concluded that the 'unapparent advantage' of insertion success rate indicated the need for further evidence gathering in this area.
