i-gel® from Intersurgical: clinical evidence listing

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

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.

Comparison of the I-gel laryngeal mask airway with the LMA-supreme for airway management in patients undergoing elective lumbar vertebral surgery.

Kang F, Li J, Chai X, Yu J, Zhang H, Tang C. J Neurosurg Anesthesiol. 2015 Jan;27(1):37-41

Patients were randomised between the two groups, with device inserted in supine position. Insertion time and attempts, airway peak pressure and complications were among results measured. i-gel provided a higher airway seal pressure in the prone position and both devices recorded low complication rates.

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.

A comparison of i-gel™ and LMA Supreme™ in anesthetized and paralyzed children

Kim H, Lee JY, Lee SY, Park SY, Lee SC, Chung CJ. Korean J Anesthesiol. 2014 Nov;67(5):317-22

100 patients were randomly assigned to either device group, with insertion success rate, leak pressure and postoperative complications among results measured. i-gel demonstrated higher leak pressure, but a longer insertion time.

Evaluation of i-gel(™) airway in children: a meta-analysis

Maitra S, Baidya DK, Bhattacharjee S, Khanna P. Paediatr Anaesth. 2014 Oct;24(10):1072-9

A total of nine studies were included using search keywords, with results finding that i-gel gave significantly higher leak pressure and ProSeal. Authors conclude it is an effective alternative to ProSeal and cLMA.
