i-gel® from Intersurgical: clinical evidence listing

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

Current practice patterns of supraglottic airway device usage in paediatric patients amongst anaesthesiologists: A nationwide survey.

Jain RA, Parikh DA, Malde AD, Balasubramanium B. Indian J Anaesth. 2018 Apr;62(4):269-279

This survey was sent to over 16,000 members of the Indian Society of Anaesthesiologists and given to delegates at the Asian Society of Paediatric Anaesthesiologists conference 2017. Percentage, mean and standard deviation were calculated. Results showed i-gel was the most commonly used device (60%) and 75% of respondents had access to second-generation supraglottic airways.

Ambu AuraOnce versus i-gel laryngeal mask airway in infants and children undergoing surgical procedures. A randomized controlled trial

Alzahem AM, Aqil M, Alzahrani TA, Aljazaeri AH. Saudi Med J. 2017 May;38(5):482-490

Randomised assignment of 112 patients to either AuraOnce or i-gel groups in which oropharyngeal leak pressure, ease of insertion and fibreoptic viewing were measured. i-gel recorded more favourable leak pressures and superior fibreoptic viewing.

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.

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.
