Airway sealing ability, success rate of insertion and adverse events were among the recorded outcomes in this study. Leak pressures and insertion success rates are similar between the two devices, however the i-gel slid out of the mouth of a small amount of patients in this scenario. Authors recommend the device should be secured more tightly.
