This article discusses the gastric channel or drain tube as a safety feature provided in supraglottic airways. Although pulmonary aspiration of gastric contents is a relatively rare event, it can be made rarer with the use of devices that include a gastric channel, particularly if they are inserted using a bougie. i-gel® is discussed.
