i-gel® from Intersurgical: clinical evidence listing

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

Paediatric i-gel evaluation under nuclear magnetic resonance (NMR)

Monclus E, Garces A, Vassileva I, Sanchez A, Banchs R. Eur J Anaesthesiol 2010; 27(47): 155

70 children who were already scheduled for a cranial MRI scan took part in this study. The epiglottis was found to be in the bowl of the i-gel® in all patients, however the device still performed well.

In vitro study of magnetic resonance imaging artefacts of six supraglottic airway devices

Zaballos M, Bastida E, del Castillo T, de Villoria JG, Jiménez C. Anaesthesia 2010; 65(6): 569-572

In this study, the artefacts created during MRI by six supraglottic airways, the Classic LMA®, the ProSeal LMA®, the LMA Unique®, the LMA Supreme®, the Ambu® disposable laryngeal mask and the i-gel® were investigated. There were no artefacts with the i-gel® or Ambu® devices.

Extraglottic airway devices for use in diving medicine - part 3: the i-gel®

Acott CJ. Diving and Hyperbaric Medicine 2008; 38(3): 124-127

This study looked at the use of i-gel® in airway management of a patient in a diving bell or deck decompression chamber. The study highlighted the potential limitations of some supraglottic airways used in Hyperbaric Medicine, such as possible cuff expansion with a decrease in pressure on decompression and change in cuff volume due to gas diffusion as the gas mixtures change, problems not associated with i-gel®. It showed that, subjectively, there was no change in the consistency of the i-gel® at 203 and 283kPa pressure and that no bubbles were detected following decompression from 203, 283 or 608kPa. The i-gel® was also preferred by the Diver Medical Technicians (DMTs) to the alternative device included in the manikin section of the study because it ‘lacked a cuff and was easier to insert from any position’.
