i-gel® from Intersurgical: clinical evidence listing

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

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.

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;201

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 proseal, supreme, and i-gel SAD in gynecological laparoscopic surgeries

Mukadder S, Zekine B, Erdogan KG, Ulku O, Muharrem U, Saim Y, Mahmut D. ScientificWorldJournal. 2015;2015:634320

105 patients were randomly distributed between the three device groups. Initial leak pressure, insertion time, ease of placement and airway morbidity results all favoured the i-gel.

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.

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.
