i-gel® from Intersurgical: clinical evidence listing

Matsunami S, Komasawa N, Minami T. J Clin Anesth. 2014 Sep;26(6):509-10

Case report of an obese patient with difficult airway inserted with an i-gel following failed facemask ventilation. After using a combination of I-gel and facemask ventilation improved sufficiently due to device's fit to the larynx.

Comment on two case reports by Schaer et al and de Graaff et al in which the importance of evaluating risk factors for difficult supraglottic airway use were highlighted. Author focuses on the importance of understanding recommended insertion techniques as part of greater knowledge of SADs.

In this double-blind study, the scenario was made more difficult by using a cervical collar. Primary aim was to compare leak pressures between devices, with success rate, insertion and fibreoptic view other parameters measured. First attempt success and leak pressure was higher with LMA Supreme. Both devices proved effective, and differences may not be clinically significant.

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.

Prospective, crossover, randomised trial of i-gel® against cLMA on 48 post-burn neck contracture patients with reduced neck movement and mouth opening. Primary outcome was overall success rate, with other measurements taken in time to ventilation, leak pressure, fibreoptic view and visualisation of square wave pattern. Success rate for i-gel® was 91.7%, against 79.2% for cLMA. i-gel® outperformed cLMA in all measurements. Authors conclude their study has ‘better clinical performance in the difficult airway management of the airway in the post burn contracture of the neck’.
