i-gel® from Intersurgical: clinical evidence listing

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

A randomized comparison between the i-gel™ and the air-Q™ supraglottic airways when used by anesthesiology trainees as conduits for tracheal intubation in children

Jagannathan N, Sohn L, Ramsey M, Huang A, Sawardekar A, Sequera-Ramos L, Kromrey L, De Oliveira GS. Can J Anaesth. 2015 Jun;62(6):587-94

96 children aged one month to six years were randomised into either i-gel or air-Q groups, with time to successful tracheal intubation the primary end point. Both served as effective conduit devices in this scenario.

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.

Performance of intubation with 4 different airway devices by unskilled rescuers: manikin study

Lee DW, Kang MJ, Kim YH, Lee JH, Cho KW, Kim YW, Cho JH, Kim YS, Hong CK, Hwang SY. Am J Emerg Med. 2015 May;33(5):691-6

LMA Classic, i-gel, PENTAX Airway Scope and Macintosh laryngoscope were all tested, with time to ventilation, intubation success rate and difficulty of intubation measured. Authors conclude that intubation with i-gel was faster and easier.

I-gel versus laryngeal mask airway-Proseal: Comparison of two supraglottic airway devices in short surgical procedures

Jadhav PA, Dalvi NP, Tendolkar BA. J Anaesthesiol Clin Pharmacol. 2015 Apr-Jun;31(2):221-5

Ease and time to insertion, airway sealing pressure and adverse events were measured in this study of 60 patients randomly allocated to i-gel and ProSeal groups. i-gel proved easier to insert and less traumatic.

Randomized comparison of the i-gel(TM) with the LMA Supreme (TM) in anesthetized adult patients

Beleña JM, Núñez M, Vidal A, Gasco C, Alcojor A, Lee P, Pérez JL. Anaesthesist. 2015 Apr;64(4):271-6

140 patients split into two groups: i-gel and LMA Supreme, with insertion time, success rate and leak pressure among the results measured. i-gel was quicker to insert but deemed not as easy. No differences were found in leak pressure.
