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.

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.

Comparison of supraglottic devices i-gel(®) and LMA Fastrach(®) as conduit for endotracheal intubation

Kapoor S, Jethava DD, Gupta P, Jethava D, Kumar A. Indian J Anaesth. 2014 Jul;58(4):397-402.

Two randomised groups were assigned either device and after insertion, blind tracheal intubation was attempted. Success at first attempt and overall intubation success rates were assessed. Authors concluded that the i-gel is 'a better device' for rescue ventilation.

Tracheal intubation through the i-gel® Supraglottic airway versus the LMA Fastrach®: A randomized controlled trial

Halgawi A, Massicotte N, Lallo A, Gauthier A, Boudreault D, Ruel M, Girard F. Anesth Analg. 2012; 114(1): 152-156

160 patients were randomised for blind intubation via i-gel® or LMA Fastrach®. First attempt and overall success rates were recorded and time to intubation was measured.

Insertion of six different supraglottic airway devices whilst wearing chemical, biological, radiation, nuclear-personal protective equipment: a manikin study

Castle N, Pillay Y, Spencer N. Anaesthesia 2011; 66(11): 983-8

Six different supraglottic airway devices, including i-gel®, were tested by 58 paramedics for speed and ease of insertion in a manikin, whilst wearing either a standard uniform or chemical, biological, radiation, nuclear-person protective equipment (CBRN-PPE). During the latter test, i-gel® was the fastest of the six to insert with a mean insertion time of 19 seconds. Overall, the wearing of CBRN-PPE has a detrimental effect on insertion time of supraglottic airways.
