i-gel® from Intersurgical: clinical evidence listing

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

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.

Pilot manikin study showed that a supraglottic airway device improved simulated neonatal ventilation in a low-resource settings

Pejovic NJ, Trevisanuto D, Nankunda JJ, Tylleskar T. Acta Paediatr. 2016 Dec;105(12):1440-1443

After brief training, 25 participants attempted insertion, with success rate and insertion time recorded. i-gel achieved 100% insertion success rate and was more effective than the face mask in establishing PPV.

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.
