i-gel® from Intersurgical: clinical evidence listing

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

Comparison of the clinical performances of Air-Qsp and i-Gel for airway management under general anesthesia with a muscle relaxant

Watanabe A, Edanaga M, Ichinose H, Yamakage M. J Clin Anesth. 2016 Nov;34:223-6

Randomised study comparing insertion attempts, insertion time and postoperative complications (among other parameters recorded) on 37 adult patients after concerns that the i-gel sometimes fails to fit or ventilate sufficiently in Japanese patients. Results showed that two patients in the Air-Qsp group failed, compared to one in the i-gel group.

A randomised trial to compare i‑gel and ProSeal™ laryngeal mask airway for airway management in paediatric patients

Nirupa R, Gombar S, Ahuja V, Sharma P. Indian J Anaesth. 2016 Oct;60(10):726-731

Prospective, randomised controlled study on 100 patients, with the primary outcome being leak pressure assessed at five minutes. i-gel recorded 'superior' pressure and shorter insertion times compared to ProSeal.

Design and implementation of the AIRWAYS-2 trial

Taylor J, Black S, Brett S, Kirby K, Nolan JP, Reeves BC, Robinson M, Rogers CA, Scott LJ, South A, Stokes EA, Thomas M, Voss S, Wordsworth S, Benger JR. Resuscitation. 2016 Sep 30. pii: S0300-9572(16)30476-2

Patient enrollment began in June 2015 for this study comparing the use by paramedics of the i-gel against endotracheal intubation in OHCA in the UK. The primary outcome is the modified Rankin Scale score at hospital discharge. The trial will enrol 9070 patients over two years.

Laryngeal mask airway ProSeal provides higher oropharyngeal leak pressure than i-gel in adult patients under general anesthesia: a meta-analysis

Maitra S, Baidya DK, Arora MK, Bhattacharjee S, Khanna P. J Clin Anesth. 2016 Sep;33:298-305

Meta-analysis of 10 RCTs to assess results when comparing the oropharyngeal leak pressure of each device. LMA ProSeal returned more favourable results, although i-gel deemed easier to insert. ProSeal also reported higher blood staining.
