i-gel® from Intersurgical: clinical evidence listing

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

Fiberoptic-guided intubation after insertion of the i-gel airway device in spontaneously breathing patients with difficult airway predicted: a prospective observational study

Arévalo-Ludeña J, Arcas-Bellas JJ, Alvarez-Rementería R, Alameda LE. J Clin Anesth. 2016 Dec;35:287-292

85 patients with at least three difficult airway predictors were included, with insertion time, intubation time and oxygen saturation outcomes measured, amongst others. No serious adverse events were recorded and no airway damage reported. Authors conclude that fibreoptic-guided intubation through the i-gel is a 'safe and effective' technique.

The i-gel Supraglottic Airway as a Conduit for Fibreoptic Tracheal Intubation - A Randomized Comparison with the Single-use Intubating Laryngeal Mask Airway and CTrach Laryngeal Mask in Patients with Predicted Difficult Laryngoscopy

Michálek P, Donaldson W, McAleavey F, Abraham A, Mathers RJ, Telford C. Prague Med Rep. 2016;117(4):164-175

Comparative study of three supraglottic airways as conduits in patients with predicted difficult laryngoscopy. Primary outcome measure was success rate of tracheal intubation through the device. No statistical difference was recorded in success rates between devices, however i-gel proved quicker to insert compared to ILMA and the intubation time was shorter compared to CTrach. i-gel is a suitable alternative to sILMA and CTrach in this scenario, and the shorter times recorded may provide an advantage in cases of difficult oxygenation.

Pillow height for i-gel® insertion: a randomized clinical trial

Fujiwara A, Komasawa N, Minami T. J Anesth. 2016;30(3):542

Randomised controlled trial of 70 patients divided into two groups by height: low (4cm), and high (12cm). Performed by novice doctors, insertion efficacy difference between groups did not differ.

Application of the LMA-Supreme™ and i-gel™ laryngeal masks during pelvic operations in adults

Wang F, Zhang R. Asian J Surg. 2016 Jan;39(1):1-5

90 patients divided into two groups, i-gel and LMA Supreme. Latter group required less time to insertion and gastric tube indwelling time, but i-gel group had fewer complications. Authors conclude both devices are safe and effective for this procedure.
