The three supraglottic devices were inserted into eight unfixed cadaver models with exposed oesophagi, connected to a water column producing both a slow and fast oesophageal pressure increase. During a fast increase of oesophageal pressure (simulated vomiting procedure) with the oesophageal lumen of the i-gel® and pLMA open, the authors reported that ‘the entire oesophageal liquid was drained to the outside without any tracheal aspiration occurring.’
