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.

Fiberoptic-guided intubation after insertion of the i-gel airway device in spontaneously breathing patients with difficult airway predicted: a prospective observational study

Arévalo-Ludeña J, Arcas-Bellas JJ, Alvarez-Rementería R, Alameda LE. J Clin Anesth. 2016 Dec;35:287-292

After i-gel insertion in 85 adult patients, general anaesthesia was induced to place an endotracheal tube by fibreoptic bronchoscope. i-gel insertion time, intubation time and oxygen saturation were monitored. Authors conclude this to be a safe and effective technique.

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.

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.
