i-gel® from Intersurgical: clinical evidence listing

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

A comparison of various supraglottic airway devices for fiberoptical guided tracheal intubation

Metterlein T, Dintenfelder A, Plank C, Graf B, Roth G. Rev Bras Anestesiol. 2017 Mar - Apr;67(2):166-171

Random assignment of 52 adult patients to different supraglottic devices, from: Laryngeal Tube, LMA, i-gel, LMA Unique, LMA Supreme and Aura-once. After successful ventilation, device positioning was examined to assess glottic opening. Glottic view ranged from 40% for Laryngeal Tube to 90%, with i-gel recording 70%.

Continuous ventilation during intubation through a supraglottic airway device guided by fiberoptic bronchoscopy: a observational assessment

Landsdalen HE, Berge M, Kristensen F, Guttormsen AB, Søfteland E. Acta Anaesthesiol Scand. 2017 Jan;61(1):23-30 

An observational study using Tracheal intubation Assisted by Bronchoscopy And Sad during Continuous Oxygenation (TABASCO) method through the i-gel. Easy intubation was secured in all patients with no adverse events recorded.

I-gel O2 resus pack, a rescue device in case of severe facial injury and difficult intubation

Baratto F, Gabellini G, Paoli A, Boscolo A. Am J Emerg Med. 2017 Jan 26

Report of two cases of attempted suicide by firearm managed with the use of the i-gel O2 Resus Pack. In both patients, laryngoscopy attempts failed before an i-gel was inserted and either fibreoptic-assisted intubation or fibreoptic bronchoscopy were performed. Authors conclude that the i-gel's properties mean the device could easily be used by untrained rescuers and might perform an important role during out-of-hospital emergency.

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

After i-gel insertion in 85 adult patients, general anaesthesia was induced to place an endotracheal tube by fibreoptic bronchoscope. i-gel insertion time, intubation time and oxygen saturation were monitored. Authors conclude this to be a safe and effective technique.

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.
