i-gel® from Intersurgical: clinical evidence listing

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 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.

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’.
