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;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 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 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.

Is i-gel® a new revolution among supraglottic airway devices? - a comparative evaluation

Jindal P, Rizvi A, Sharma JP. Middle East J Anesthesiol. 2009; 20(1): 53-58

This study compared i-gel® to two other supraglottic airways in respect of haemodynamic changes, including heart rate, systolic and diastolic blood pressure, mean arterial pressure and rate pressure product. The authors concluded that ‘i-gel® effectively conforms to the perilaryngeal anatomy despite the lack of an inflatable cuff, it consistently achieves proper positioning for supraglottic ventilation and causes fewer haemodynamic changes as compared to other supraglottic airway devices.’

Evaluation of four airway training manikins as patient simulators for the insertion of eight types of supraglottic airway devices

Jackson KM, Cook TM. Anaesthesia. 2007 Apr;62(4):388-93

The airway arm of this trial compared devices including i-gel, Cobra, SLIPA and Laryngeal Tube Suction II. Each device was inserted twice into each manikin by ten anaesthetists, with each insertion scored and ranked. No one manikin outranked the others for all devices. i-gel insertion was 'significantly the easiest'.
