i-gel® from Intersurgical: clinical evidence listing

Sen S, Mitra K, Ganguli S, Mukherji S. Anesth Essays Res. 2018 Jan-Mar;12(1):288-290

Peri-operative management of patients with haemophilia involves the risks of excessive bleeding. This is especially true when securing the patient’s airways during anaesthesia with standard instrumentation (e.g. direct laryngoscopy), as this could lead to severe haemorrhage. Therefore, this case study assessed the efficacy of the i-gel in the airway management of a patient with haemophilia undergoing laparoscopic cholecystectomy.

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.

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.
