Abukawa Y, Hiroki K, Iwakiri H, Fukuda T, Ozaki M. J Anesth. 2016;30(2):199-204

130 patients aged 7 months to 13 years monitored under general anaesthesia, with size selection based on patient's body weight. Average insertion length grew longer with increasing height and weight. Authors conclude a line could be drawn on sizes 1.5 and 2 only.

270 patients aged 0-12 years not requiring tracheal intubation were recruited. After induction, thenar eminence dimensions were measured and compared with the patient's inserted i-gel. Authors conclude their results showed that the dimensions of thenar eminence fitted the weight-based size selection of i-gel, and that it could be a practical way to choose the correct size device.

In this case of a 13-year-old patient, the i-gel was inserted passed the swollen tonsil to give unventful mechanical ventilation and no postoperative complications or bleeding of the tonsil.

Patients were randomly assigned to i-gel size 2 or LMA Classic size 2 groups, with target end-tidal sevoflurane concentration maintained for 8-10 minutes before insertion. This concentration was decreased in subsequent patients depending on response according to Dixon method. Authors conclude i-gel insertion can be accomplished at nearly half the concentration required for LMA Classic.

30 children induced with sevoflurane in oxygen and administered atracurium intravenously. Oropharyngeal leak pressure in neutral, maximum flexion and maximum extension were primary outcomes measured. In extreme flexion of head and neck, caution is warranted during ventilation.
