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

The association between thenar eminence and i-gel dimensions in paediatric patients

Cuvas Apan O, Apan A. Rev Bras Anestesiol. 2016;66(2):171-5

270 patients aged 0-12 years not requiring tracheal intubation were recruited. After induction, thenar eminence dimensions were measured and compared with the patient's inserted i-gel. Authors conclude their results showed that the dimensions of thenar eminence fitted the weight-based size selection of i-gel, and that it could be a practical way to choose the correct size device.

Randomised comparison of the effectiveness of the laryngeal mask airway supreme, i-gel and current practice in the initial airway management of out of hospital cardiac arrest (REVIVE-Airways): a feasibility study

Benger J, Coates D, Davies S, Greenwood R, Nolan J, Rhys M, Thomas M, Voss S. Br J Anaesth. 2016;116(2):262-8

A cluster randomised trial of paramedics within one ambulance service in England over a 12-month period, split into groups using either the i-gel or LMA Supreme or usual practice for all patients with non-traumatic adult OHCA. Primary outcome was study feasibility, including recruitment and protocol adherence. Secondary outcomes included survival to hospital discharge and to 90 days. 184 of 535 paramedics consented, with 615 patients recruited. The LMA Supreme arm was suspended following 'adverse incidents'. No differences were reported 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.

i-gel as alternative airway tool for difficult airway in severely injured patients

Häske D, Schempf B, Niederberger C, Gaier G. Am J Emerg Med. 2016;34(2):340

Report of two cases where i-gel was successfully used in a prehospital setting on patients with severe head and neck trauma. Authors suggest that, on evidence, i-gel is an 'appropriate primary airway tool'.
