i-gel® from Intersurgical: clinical evidence listing

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

Comparison of the Macintosh laryngoscope and blind intubation via the iGEL for intubation with cervical spine immobilization: A randomized, crossover, manikin trial

Gawlowski P, Smereka J, Madziala M, Szarpak L, Frass M, Robak O. Am J Emerg Med. 2017 Mar; 35(3): 484-487.

Paramedics performed standard intubation and blind intubation in three airway scenarios. Results show that blind intubation with the i-gel was superior to ETI performed by paramedics.

Tracheal intubation through I-gel performed during simulated cardiopulmonary resuscitation

Wojewodzka-Zelezniakowicz M, Majer J. Am J Emerg Med. 2017 Jan 16.

Manikin study to compare the efficacy of ETI performed by 27 nurses using the i-gel as a guide with/without chest compressions. Results showed that in this scenario, nurses were able to perform blind intubation using the i-gel with 'high efficiency'.

Comparison between supraglottic airway devices and endotracheal tubes in patients undergoing laparoscopic surgery: A systematic review and meta-analysis

Park SK, Ko G, Choi GJ, Ahn EJ, Kang H. Medicine (Baltimore). 2016 Aug;95(33):e4598

In total, 17 randomised controlled trials were identified fitting the parameters outlined. Incidence of postoperative complications including cough at removal, dysphagia, sore throat and laryngospasm were higher in the ETT group. However no differences were shown regarding insertion success at first attempt and insertion time, among others.

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.
