Smith P, Bailey CR. Anaesthesia. 2015 Jan;70(1):84-92
Review of 62 published articles, including 14 randomised controlled trials, comparing i-gel with other supraglottic airway devices in children. Leak pressure was found to be the most common primary outcome. Authors conclude i-gel is 'at least equivalent' to other devices, and may give higher leak pressures and improved fibreoptic view of the glottis.
