This paper describes the history of the gastric channel in supraglottic airways, providing case reports and performance comparisons between devices. The section on the i-gel® states that the device has inferior seal pressure compared to the LMA Proseal®, but that drainage through the gastric channel was comparable. The i-gel® is quicker and easier to place than standard LMAs. A case report is included which describes the successful use of a size five i-gel® in a 63-year-old man with a difficult airway.
