i-gel® from Intersurgical: clinical evidence listing

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

A systematic review and meta-analysis of the i-gel(®) vs laryngeal mask airway in adults

de Montblanc J, Ruscio L, Mazoit JX, Benhamou D. Anaesthesia. 2014 Oct;69(10):1151-62

31 adult randomised controlled trials on i-gel against the LMA were assessed, finding that the main clinical advantage of i-gel was less frequent sore throat.

Evaluation of chest compression effect on airway management with air-Q®, aura-i®, i-gel®, and Fastrack® intubating supraglottic devices by novice physicians: a randomized crossover simulation study

Komasawa N, Ueki R, Kaminoh Y, Nishi SI. J Anesth 2014; 28(5): 676-80

A group of 20 novice physicians inserted the named devices into manikins with or without chest compressions, whereupon insertion time and successful ventilation rate were measured. In cases of successful ventilation, blind tracheal intubation via the inserted device was performed. Chest compression did not significantly decrease ventilation success rates in each device, however insertion time with i-gel® did suffer, according to the authors.

Insertion time and successful ventilation rate were measured, with the latter unaffected by chest compression.

Emergency airway management by paramedics: comparison between standard endotracheal intubation, laryngeal mask airway, and I-gel

Leventis C, Chalkias A, Sampanis MA, Foulidou X, Xanthos T. Eur J Emerg Med. 2014 Oct;21(5):371-3

72 briefly-trained paramedics were allocated to intubate a manikin. Success rate was higher, and insertion time 'significantly' shorter for the i-gel group.

Emergency airway management by paramedics: comparison between standard endotracheal intubation, laryngeal mask airway, and I-gel

Leventis C, Chalkias A, Sampanis M A, Foulidou X, Xanthos T. Eur J Emerg Med. 2014 Oct; 21(5): 371-3

Study to investigate intubation skill levels of 72 paramedics using ETI, LMA and i-gel® in a manikin model. The success rate was higher, and the insertion time lower for those using i-gel®. There was a ‘statistically significant association’ between experience level and insertion time of LMA. Authors conclude that paramedics should ‘lay greater emphasis on airway management using supraglottic devices, especially i-gel®’.
