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.

Dexmedetomidine infusion as an anesthetic adjuvant to general anesthesia for appropriate surgical field visibility during modified radical mastectomy with i-gel®: a randomized control study

Gupta K, Rastogi B, Gupta PK, Singh I, Singh VP, Jain M. Korean J Anesthesiol. 2016 Dec;69(6):573-578.

Sixty female patients split in to equal groups, one receiving a dexmedetomidine dose, the other saline as control. Patients receiving the dose infusion showed significantly less bleeding in the surgical field.

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.
