i-gel® from Intersurgical: clinical evidence listing

A comprehensive list of all known published clinical evidence on the device

The Difficult Airway Society 2015 guidelines and the sacred cows of routine airway management

Cook TM, Kelly FE. Anaesthesia. 2016 Apr;71(4):466-7

Based on the findings of the DAS 2015 guidelines, the authors argue that evidence suggests 2nd generation supraglottic airway devices perform better than 1st generation equivalents, and that 2nd gen should be used for airway rescue and routine airway management.

Challenge to pediatric anatomical variation: Can we draw the ideal line on the pediatric I-gel?

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.

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.

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.
