i-gel® from Intersurgical: clinical evidence listing

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

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.

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.

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 chest compression effect on airway management with air-Q, aura-i, i-gel, and Fastrack intubating supraglottic devices by novice physicians: a randomized crossover simulation study

Komasawa N, Ueki R, Kaminoh Y, Nishi S. J Anesth. 2014 Oct;28(5):676-80

Insertion time and successful ventilation rate were measured, with the latter unaffected by chest compression.
