Male patients require higher optimal effect-site concentrations of propofol during i-gel insertion with dexmedetomidine 0.5 μg/kg

Choi JJ, Kim JY, Lee D, Chang YJ, Cho NR, Kwak HJ. BMC Anesthesiol. 2016 Mar 22;16:20

40 patients were split into equal gender groups prior to insertion. The EC50 of propofol in men was approximately 40% higher than in women. Gender should be considered when determining optimal dose of propofol, according to the authors.

Postoperative sore throat: a systematic review

El-Boghdadly K, Bailer R, Wiles M. Anaesthesia 2016;71(6):706-17

Review into prevalence of sore throat after use of supraglottic airway devices against tracheal intubation in general anaesthesia. Authors suggest that, in adults, i-gel results in a lower incidence of post-operative sore throat.

The association between thenar eminence and i-gel dimensions in paediatric patients

Cuvas Apan O, Apan A. Rev Bras Anestesiol. 2016;66(2):171-5

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.
