i-gel® from Intersurgical: clinical evidence listing

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

A comparison of QTc intervals after laryngoscopic intubation and i-gel insertion during propofol-sevoflurane anaesthesia

Byon HJ, Song J, Shinn HK, Song K, Lee C, Lim H. Minerva Anestesiol. 2016 Sep;82(9):950-6

Patients were randomly assigned to either the i-gel or intubation group and induced using propofol or sevoflurane. Peak QTc interval was lowever in the i-gel group. Authors conclude the i-gel 'may be advantageous' to patients at risk of QTc prolongation.

A comparison of the I-Gel supraglottic device with endotracheal intubation for bronchoscopic lung volume reduction coil treatment

Arevalo-Ludeña J, Arcas-Bellas JJ, Alvarez-Rementería R, Flandes J, Morís L, Muñoz Alameda LE. J Clin Anesth. 2016 Jun;31:137-41

Prospective observational study on 22 patients comparing the use of i-gel against orotracheal intubation. Tidal volume, peak pressure, gas leaks and adverse events were recorded. Authors conclude i-gel is 'an effective and safe alternative' to OTI in this scenario.

Intubation Success through I-Gel® and Intubating Laryngeal Mask Airway® Using Flexible Silicone Tubes: A Randomised Noninferiority Trial

Naik L, Bhardwaj N, Sen IM, Sondekoppam RV. Anesthesiol Res Pract. 2016;2016:7318595

Study on 120 patients comparing intubation success through i-gel or ILMA. Overall success rate proved lower with i-gel in this scenario, with no differences in secondary outcomes.

Successful i-gel insertion combined with Macintosh laryngoscope with a swollen tonsil

Komasawa N, Nishihara I, Minami T. J Clin Anesth. 2016;28:89-90

In this case of a 13-year-old patient, the i-gel was inserted passed the swollen tonsil to give unventful mechanical ventilation and no postoperative complications or bleeding of the tonsil.

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.
