i-gel® from Intersurgical: clinical evidence listing

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

A randomized controlled trial of the effect of preoperative dexmedetomidine on the half maximal effective concentration of propofol for successful i-gel insertion without muscle relaxants

Jang YE, Kim YC, Yoon HK, Jeon YT, Hwang JW, Kim E, Park HP. J Anesth. 2015 Jun;29(3):338-45

37 patients were randomly allocated to either a dexmedetomidine or control (saline) group. Authors conclude that preoperative dexmedetomidine reduced the EC50 of propofol.

An evaluation of the I-gel supraglottic airway in 70 pediatric patients

Yeoh TY, Chan KB, Yeo LS, Liu EH, Pan TL. J Anesth. 2015 Apr;29(2):295-8

An evaluation of 70 children undergoing general anaesthesia, with insertion time, leak pressure and gastric tube insertion among the results. Overall insertion success was 96%.

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 S. J Anesth. 2014 Oct;28(5):676-80

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

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.

Utility of the Aintree Intubation Catheter in fiberoptic tracheal intubation through the three types of intubating supraglottic airways: a manikin simulation study

Ueki R, Komasawa N, Nishimoto K, Sugi T, Hirose M, Kaminoh Y. J Anesth. 2014 Jun;28(3):363-7

Manikin trial comparing LMA Fastrach-Single Use, air-Q and I-gel with success rate of tracheal intubation, intubation time and collision with the glottis measured. Results suggest Fastrach took longer to intubate with a higher failure rate, and the Aintree Intubation Catheter reduces collisions.
