i-gel® from Intersurgical: clinical evidence listing

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

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.

A comparative study of Laryngeal Mask Airway size 1 vs. i-gel size 1 in infants undergoing daycare procedures

Pant D, Koul A, Sharma B, Sood J. Paediatr Anaesth. 2015 Apr;25(4):386-91

Forty children 2-5kg in body weight were allocated to either i-gel or LMA Classic groups, with oropharyngeal seal pressure the primary outcome measured. Results showed that i-gel OSP was higher and statistically significant.

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

A single-blind randomised trial on 61 patients allocated into i-gel and LMA Classic groups. Airway placement was categorised into three groups: first, second and third attempts. Success rate, insertion time and postoperative complications were measured. i-gel a 'good alternative' to cLMA in this scenario.

Comparison of five 2nd-generation supraglottic airway devices for airway management performed by novice military operators.

Henlin T, Sotak M, Kovaricek P, Tyll T, Balcarek L, Michalek P. Biomed Res Int. 2015;2015:201898

Prospective, randomised, single-blinded study comparing five supraglottic airway devices (ProSeal LMA, Supreme LMA, SLIPA, Laryngeal Tube Suction-D and i-gel) in low light conditions on 505 patients after induction of general anaesthesia. Insertion time was shortest in Supreme LMA and i-gel groups.

A performance comparison of the paediatric i-gel with other supraglottic airway devices.

Smith P, Bailey CR. Anaesthesia. 2015 Jan;70(1):84-92

Review of 62 published articles, including 14 randomised controlled trials, comparing i-gel with other supraglottic airway devices in children. Leak pressure was found to be the most common primary outcome. Authors conclude i-gel is 'at least equivalent' to other devices, and may give higher leak pressures and improved fibreoptic view of the glottis.
