i-gel® from Intersurgical: clinical evidence listing

A comprehensive list of all known published clinical evidence on the device

Use of the i-gel® laryngeal mask for management of a difficult airway

Emmerich M, Dummler R. Anaesthesist 2008; 57(8): 779-781

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.

Fibreoptic intubation through an i-gel® supraglottic airway in two patients with predicted difficult airway and intellectual disability

Michalek P, Hodgkinson P, Donaldson W. Anesth Analg 2008; 106(5): 1501-1504

This case study describes successful fibreoptic guided tracheal intubation through the i-gel® in two uncooperative adult patients with learning disability and predicted difficult airway. The i-gel® maintained the airway immediately after induction, allowing oxygenation and ventilation. Fibreoptic identification of the laryngeal inlet was successful on the first attempt and a tracheal tube inserted into the trachea, without complication, in both patients.

The i-gel® airway for ventilation and rescue ventilation

Sharma S, Rogers R, Popat M. Anaesthesia 2007; 62(4): 412-423

This case report concerns use of an i-gel® on a teenage patient scheduled for closure of colostomy. Two years previously he had a grade 3 (Cormack & Lehane) view at laryngoscopy. On this occasion there were no clinical features to predict difficult intubation.Laryngoscopy revealed a grade 4 view. Two attempts at tracheal intubation with a gum elastic bougie failed. A cLMA® was inserted. Despite providing satisfactory ventilation, two attempts at fibreoptic intubation through the device failed. A size 4 i-gel® was inserted and satisfactory ventilation achieved. After fibreoptic confirmation of a good view of the vocal cords, a size 6.5mm cuffed tracheal tube was successfully passed through the i-gel® blindly into the trachea at the first attempt. The i-gel® was left in place until extubation.
