i-gel® from Intersurgical: clinical evidence listing

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

Influence of Head and Neck Position on Oropharyngeal Leak Pressure and Cuff Position with the ProSeal Laryngeal Mask Airway and the I-Gel: A Randomized Clinical Trial

Mishra SK, Nawaz M, Satyapraksh MV, Parida S, Bidkar PU, Hemavathy B, Kundra P. Anesthesiol Res Pract. 2015;2015:705869

After induction of anaesthesia and device insertion, head position was ranomly changed from neutral to flexion, extension and lateral rotation. Leak pressure, fibreoptic view and ventilation scores were among the results measured. Effective ventilation can be performed with both devices, but 'extreme precaution' should be taken in flexion position in ProSeal.

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.

Comparison of the Disposable Streamlined Liner of the Pharynx Airway and the Disposable I-gel in Anaesthetized, Paralyzed Adults: A Randomized Prospective Study.

El-Radaideh K, Alhowary AA, Bani Hani D. Anesthesiol Res Pract. 2015;2015:971059

Patients were evenly distributed between the two device groups, with ease and number of insertions, insertion speed and leak pressure amongst outcomes measured. SLIPA appeared to be quicker to insert, however blood staining incidence was higher.

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.

Does prewarming the i-gel supraglottic airway device fit the larynx better compared to keeping it at room temperature for non-paralysed, sedated patients: a randomised controlled trial

Komasawa N, Nishihara I, Tatsumi S, Minami T. BMJ Open. 2015 Jan 13;5(1):e006653

Patients were assigned to a warm (at 42 degrees centigrade) or control room temperature group. Number of attempts until successful insertion and sealing pressure were compared. Authors conclude that pre-warming did not increase insertion success rate.
