i-gel® from Intersurgical: clinical evidence listing

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

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.

I-gel Versus LMA-Fastrach Supraglottic Airway for Flexible Bronchoscope-Guided Tracheal Intubation Using a Parker (GlideRite) Endotracheal Tube: A Randomized Controlled Trial

Moore A, Gregoire-Bertrand F, Massicotte N, Gauthier A, Lallo A, Ruel M, Todorov A, Girard F. Anesth Analg. 2015 Aug;121(2):430-6

120 patients were randomly assigned to i-gel or LMA Fastrach groups, with tracheal intubation and mask insertion success rate measured. Use of i-gel as a conduit in this scenario is equivalent to Fastrach, however gives shorter intubation times and a better visualisation of the glottic opening.

The i-gel® supraglottic airway- a useful tool in case of difficult fibreoptic intubation

Emmerich M, Tiesmeier J. Minerva Anestesiol 2012; 78(10): 1169-70

A 69-year-old man with a history of difficult intubation could not be intubated via conventional bronchoscopy. Different ETT sizes and airway manoeuvres were tried without success, until the bronchoscope was properly placed through a size 5 i-gel. Operation was completed without complication and the patient reported no neck discomfort or difficulty breathing.
