Presumed air entrainment through the gastric port of a paediatric i-gel® device - manufacturer's reply

Chapman D. Anaesthesia. 2017 Feb;72(2):263-264.

Response to the letter from Seeley et al. Manufacturer posits that the reason for light anaesthesia and hence air entrainment, may have been caused by the tip of the device not being located in the upper oesophageal opening and the non-inflatable cuff located against the laryngeal framework, meaning the airway and gastric channels would not be isolated from each other. In the event described by the case report, reference to the user guide would suggest reinsertion of the device using a gentle jaw thrust, deep rotation or triple maneouvre to achieve optimum depth of insertion.

Presumed air entrainment through the gastric port of a paediatric i-gel device

Seeley JP, Pearson K, Baxter A. Anaesthesia. 2017 Feb;72(2):262-263.

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.
