Prospective observational study on 22 patients comparing the use of i-gel against orotracheal intubation. Tidal volume, peak pressure, gas leaks and adverse events were recorded. Authors conclude i-gel is 'an effective and safe alternative' to OTI in this scenario.

120 patients were randomly assigned to i-gel or LMA Fastrach groups, with tracheal intubation and mask insertion success rate measured. Use of i-gel as a conduit in this scenario is equivalent to Fastrach, however gives shorter intubation times and a better visualisation of the glottic opening.

A 69-year-old man with a history of difficult intubation could not be intubated via conventional bronchoscopy. Different ETT sizes and airway manoeuvres were tried without success, until the bronchoscope was properly placed through a size 5 i-gel. Operation was completed without complication and the patient reported no neck discomfort or difficulty breathing.
