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.

Endotracheal intubation versus supraglottic airway placement in out-of-hospital cardiac arrest: a meta-analysis

Benoit et al. Resuscitation. 2015 Aug;93:20-6

A literature search was carried out in PubMed, Scopus, and the Cochrane database. Studies where intubation and SADs were compared in prehospital cardiac arrest patients were found and a meta-analysis was carried out. Outcomes measured were ROSC, survival to hospital admission, survival to hospital discharge, and neurologically intact survival until discharge.

Success rate of airway devices insertion: laryngeal mask airway versus supraglottic gel device.

Pournajafian A, Alimian M, Rokhtabnak F, Ghodraty M, Mojri M. Anesth Pain Med. 2015 Mar 30;5(2):e22068.

61 patients were randomised for cLMA or I-gel insertion for brief orthopaedic surgery. Insertion time, success/failure rate, and incidence of complications (sore throat, hoarseness, bleeding) were all recorded. The devices were comparable, with a low incidence of complications overall and no instances of blood in the airway or on the device. The I-gel is therefore an acceptable alternative to the LMA Classic.

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.

Comparison of learning performance of 2 intubating laryngeal mask airways in novice: A randomized crossover manikin study.

Liu ZJ, Yi J, Chen WY, Zhang XH, Huang YG. Medicine (Baltimore). 2017 May;96(19):e6905.

46 doctors with no intubation experience were given 20 minutes of airway training and a short practice session with the i-gel and Aura-I. They were then asked to insert each device into a manikin in random order and to attempt intubation through each airway. Time to ventilation, first-attempt and overall intubation success, incidence of gastric inflation, ease of insertion, view of the vocal cords, and insertion score were all recorded and compared. Participants attempted the same tasks at a 3-month follow-up session. First-attempt and overall success rates for intubation were high and comparable, with only 1 patient failing to intubate via the Aura-I at follow-up. Performance of the devices was generally comparable. Time to intubation was shorter with the i-gel at both time points. Participants also reported that the i-gel was easier to use. These results may be due to the lack of inflatable cuff.
