The i-gel supraglottic airway is a 2nd generation supraglottic airway device (SAD) with a soft anatomically preformed non-inflatable cuff. The device is available in seven different sizes covering a range from newborns to large male adults.
The i-gel may be used for airway maintenance in a broad spectrum of elective surgeries in fasted patients. Its insertion parameters and overall insertion success rates are comparable to established laryngeal mask airways.
Oropharyngeal seal pressures are higher than in 1st generation SADs and allow intermittent positive pressure ventilation even during laparoscopic procedures or for moderately obese patients. Temporary postoperative complaints, such as sore throat or swallowing difficulties are generally lower than in most other SADs.
Serious adverse events including aspiration of gastric contents or permanent nerve damage are extremely rare. Features of the i-gel make it a very useful conduit for fibrescope-guided tracheal intubation in patients with predicted or unexpected difficult airways.
The device may be used as an airway maintenance device in cardiopulmonary resuscitation scenarios.
