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.
