i-gel® from Intersurgical: clinical evidence listing

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

Comparison of the i-gel and other supraglottic airways in adult manikin studies: systematic review and meta-analysis

An J, Nam SB, Lee JS, Lee J, Yoo H, Lee HM, Kim MS. Medicine (Baltimore). 2017 Jan;96(1):e5801

Authors conducted a specialised search of study databases for eligible randomised controlled trials, setting device insertion time and first-attempt insertion success rate as their primary outcomes. In the 14 RCTs included, i-gel was faster than the majority of other supraglottic airways, with only three others recording shorter insertion times. Authors concluded that the 'unapparent advantage' of insertion success rate indicated the need for further evidence gathering in this area.

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.

I-Gel is a suitable alternative to endotracheal tubes in the laparoscopic pneumoperitoneum and trendelenburg position

Lai CJ, Liu CM, Wu CY, Tsai FF, Tseng PH, Fan SZ. BMC Anesthesiol. 2017 Jan 6;17(1):3

Randomised controlled trial of 40 patients divided equally between i-gel and ETT groups. Leak fraction was the primary outcome, defined as leak volume divided by inspired tidal volume. In the LPT position, no difference was recorded in the leak fraction. In the i-gel group there was 'notably less' leakage in LPT position than in supine - this difference was not observed in the ETT group. Incidence of postoperative sore throat was significantly lower in the i-gel group.

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.
