i-gel® from Intersurgical: clinical evidence listing

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

Lubrication of the i-gel® supraglottic airway and the classic laryngeal mask airway

Chapman D. Anaesthesia 2010; 65(1): 89

This letter is a response to the 2009 study by Janakiraman (see page 7) et al. which compared the i-gel® to the LMA Classic®. In that study, the authors stated that the devices were lubricated along the tip and the posterior surface. However, the correct lubrication procedure for the i-gel® is different; the thermoplastic material used to make the device is tacky until lubricated and requires lubrication on all four sides of the cuff.

Phenomenon with i-gel® airway: a reply

Chapman D. Anaesthesia 2009; 64(2): 228

This letter is a reply to Baxter (2008). Baxter described two incidents where air was ‘entrained through the suction port’ leading to decreased end-tidal sevoflurane and lightened anaesthesia. This response suggests that the devices in question may not have been inserted fully, meaning that the airway and gastric channels were not isolated from each other. To ensure full insertion takes place, users should make sure that the level of anaesthesia, patient position and insertion method are correct.
