This, the first data collection study on the extent of oesophageal insufflation when oropharyngeal leak pressures are exceeded, used the i-gel® inserted into cadavers. Compared alongside LMA Supreme®, LMA ProSeal®, LTS-DTM, LTS IITM and Combitube®, performance was measured in a surgically-closed trachea to replicate total airway obstruction. Volume of insufflation from controlled ventilation was measured at inspirator pressures of 20, 40 and 60 mbar, with the former producing no insufflation with any device.

Three groups of 40 elective patients each were assigned to i-gel®, LMA Supreme® and Laryngeal Tube Suction-D for a prospective, randomised and comparative study of position (fibre optic) and clinical performance data during surgery. Speed of insertion and success rates, leak pressure, dynamic airway compliance, and signs of postoperative airway morbidity were recorded, with i-gel® registering a 95% insertion success rate and the highest airway compliance. In conclusion, all devices were considered suitable for ventilation in elective surgery.
