In this study, the i-gel® was compared to the cLMA, ProSeal and Ambu Aura OnceTM supraglottic airways. 40 patients were assigned to each of the four groups for insertion of one of the airways during surgery. Ease of insertion and insertion time were comparable for all devices. The ProSeal and Aura OnceTM airways had significantly better placement and seal pressures. Airway morbidity did not occur in any of the groups. The cLMA was significantly more likely to cause postoperative sore throat.

In this case report, the i-gel® was used as a conduit for intubation in a patient who was known to have problems with intubation. Direct laryngoscopy was not possible, but ventilation and a good fibreoptic view of the glottis were achieved by using the i-gel®. Intubation via the device was completed successfully using a 6.0mm cuffed endotracheal tube.
