The Ambu® Aura GainTM is a relatively new 2nd generation Supraglottic Airway Device (SGA) with a second port, providing gastric access to drain gastric content and air and it has an intergrated bite-block that helps avoiding rotation of the SGA. It has been described and it is known from daily routine, that SGA in edentulous patient provide inferior oropharyngeal leak pressure (OLP). The aim of the study is to evaluate if the placement of a gastric tube through the second orifice leads to better OLP and lowers the number of intervention needed for replacing the SGA. The study also evaluates the OLP after 15 minutes and after 30 minutes.
