i-gel® from Intersurgical: clinical evidence listing

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

Layperson mouth-to-mask ventilation using a modified i-gel laryngeal mask after brief onsite instruction: a manikin-based feasibility trial.

Schälte G, Bomhard LT, Rossaint R, Coburn M, Stoppe C, Zoremba N, Rieg A. BMJ Open. 2016 May 12;6(5):e010770.

100 participants were presented with a manikin and an airway management package containing a labelled i-gel and a mouthpiece with a filter which connected to the i-gel connector. They were given a sheet of instruction and attempted to ventilate the manikin. Time to ventilation, success rate, i-gel position and direction, and participant age and first aid experience were recorded. Participants rated their success and the ease of use, stated whether they would use the device in an emergency, and stated whether they would feel comfortable performing ventilation with the device. The three devices were generally comparable. However, the i-gel was quicker to insert, most likely due to the lack of inflatable cuff. The incidence and severity of both perioperative and postoperative complications was low.

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.
