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.
