Alzahem AM, Aqil M, Alzahrani TA, Aljazaeri AH. Saudi Med J. 2017 May;38(5):482-490

Randomised assignment of 112 patients to either AuraOnce or i-gel groups in which oropharyngeal leak pressure, ease of insertion and fibreoptic viewing were measured. i-gel recorded more favourable leak pressures and superior fibreoptic viewing.

Case report of light anaesthesia in a patient with a size 1.5 i-gel, despite adequate inspired concentration of sevoflurane and optimum positioning of the device by experienced operators. Entrainment was confirmed by capnography. No harm came to the patient. Authors pose the question of whether the gastric port inlet is positioned too anteriorly in paediatric i-gel sizes.

105 patients were including in this paediatric study, with primary outcomes including leak pressure and respiratory dynamic data. Authors conclude that the 'i-gel presented a better sealing effect and fewer adverse reactions.'
