Study on 120 patients comparing intubation success through i-gel or ILMA. Overall success rate proved lower with i-gel in this scenario, with no differences in secondary outcomes.

In the original post, and in response to Cook's study on abandoning vintage laryngeal masks (Br J Anaesth. 2015 Oct;115(4):497-9), Pearson cautions against the 'universal replacement of 1st generation devices' especially considering sub-group care (paediatrics), versatility, training and cost, and instead suggests there should not be a one-size-fits-all approach. Pearson also comments on the significant move towards the use of i-gel in her hospital.

In response to this, Cook suggests clinicians use the best performing and safest device where available as first choice. Cook makes mention of the two published meta-analyses on i-gel in children: by Choi GJ and Maitra S.

Randomised human cadaver study comparing Laryngeal Tube, EasyTube, LMA Classic, i-gel, ETI and BVM effect on protection against regurgitation and aspiration during CPR. Five minutes of CPR was administered according to 2010 European Resuscitation Council Guidelines. Aspiration was detected in two out of five cadavers with i-gel, while none were recorded when using ETI. Study provides experimental evidence that ETI offers superior protection during CPR.
