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.

Sixty paediatric patients were split between the two groups, with scans of head and neck performed after confirmation of device placement. Both devices 'significantly' reduced the area of glottis opening. i-gel produced greater dilation of upper oesophogeal sphincter. Authors conclude more studies needed to test these results to 'reduce morbidity on pediatric airway'.

Online searches of popular databases resulted in 14 randomised controlled trials being included. Overall, leak pressure was higher with ProSeal, but i-gel was faster to insert, had lower incidence of blood staining on removal and sore throat.

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.

Original post by Pearson K. Reply by Cook TM. Anaesthesia Correspondence Website. 2016. Accessed 22 May.
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.
