100 patients were randomly assigned to either device group, with insertion success rate, leak pressure and postoperative complications among results measured. i-gel demonstrated higher leak pressure, but a longer insertion time.

Reported failure of an i-gel® and an Ambu® AuraOnceTM to ventilate a drowning victim due to changes in lung physiology following inhalation of water requiring ventilation pressures up to 40cmH20. Authors say that supraglottic airways, thanks to rapid insertion, are recommended for resuscitation as they facilitate the continuation of cardiac compression, however low leak pressures may cause inadequate ventilation and entrainment of air into the stomach of drowning victims.

A 36-year-old morbidly obese pregnant woman presented for emergency caesarian was anaesthetised using RSI. To limit insertion attempts an i-gel® was used, successfully inserted at the first attempt and a healthy baby was delivered with no further complication to the mother. Concluded that i-gel® is likely to be the better airway management device when speed is of the essence, compared to other laryngeal masks.

This report details the use of an i-gel® to provide an airway for a 63-year-old male with severe subglottic swelling. Two prior attempts at insertion of a gum elastic bougie failed and facemask ventilation was ineffective. A well-known brand of laryngeal mask was inserted, but ventilation was impossible, so it was removed and replaced with an i-gel®. Subsequent intubation through the i-gel® was performed successfully with a flexible fibrescope.
