i-gel® from Intersurgical: clinical evidence listing

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

Presumed air entrainment through the gastric port of a paediatric i-gel device

Seeley JP, Pearson K, Baxter A. Anaesthesia. 2017 Feb;72(2):262-263.

Case report of light anaesthesia in a patient with a size 1.5 i-gel, despite adequate inspired concentration of sevoflurane and optimum positioning of the device by experienced operators. Entrainment was confirmed by capnography. No harm came to the patient. Authors pose the question of whether the gastric port inlet is positioned too anteriorly in paediatric i-gel sizes.

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.

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.

What are the factors associated with successful I-gel™ insertion and uneventful anaesthesia in children under age two?

Magne C, Pichenot V, Didier P, Bérard L, Lejus-Bourdeau C. Anaesth Crit Care Pain Med. 2016 Sep 23

Size 1 and 1.5 were used in this study on patients under the age of two. Successful insertion at the first attempt was recorded in 75% of cases.
