Subjects with out-of-hospital cardiac arrest were allocated to either the i-gel or Portex Soft Seal laryngeal mask group, within a large Australian ambulance group. Primary outcome was successful insertion of the airway. The i-gel had a significantly higher success rate than Portex Soft Seal and significantly lower median ease of insertion scores.

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.
