Elgebaly AS, Eldabaa AA. Anesth Essays Res. 2014 May-Aug;8(2):216-22

49 adult patients were randomly assigned between each device group, with fentanyl doses, hemodynamic parameters and mean arterial pressure among results taken at various points throughout the procedure. i-gel requires less anaesthetic doses in this scenario.

Ransomised control trial comparing LMA Supreme with i-gel in 70 patients, with leak pressure, insertion success rates and leak fractions among the outcomes measured. While no post-operative complications were reported with i-gel, three patients suffered mild sore throat and one had mucosal injury in the Supreme group. i-gel had a higher but 'clinically inconsequential' leak fraction.

In this survey distributed to the members of APAGBI, the current usage of supraglottic airway devices in routine practice and difficult airways in the UK was assessed. Of the 244 members, 88% preferred the use of first-generation devices, with the most important design feature being the availability of a complete range of sizes. 77% would like to see more randomised controlled trials on SAD safety in children.

Prospective, randomised study conducted in 80 fasted patients, split equally between i-gel® and PLMA, of ASA grades I/II. Ease and speed of insertions were primary outcomes measured, with i-gel® significantly quicker and easier than PLMA. Post-operative complications also lower in i-gel® group.
