In this study, 85 patients were randomised into two groups for ventilation via LMA Supreme® or i-gel® supraglottic airways. Ease of insertion, seal pressure, ventilatory parameters and insertion of a gastric tube were all recorded. Both devices were easy to insert, with the SupremeTM and i-gel® being inserted on the first attempt in 95.2 and 86% of cases respectively. Performance was generally comparable.
