i-gel® from Intersurgical: clinical evidence listing

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

Should supraglottic airway devices be used by lifeguards at all?

Baker P, Webber J. Anaesthesia 2014; 69(8): 928-9

A further response to Adelborg et al (Anaesthesia. 2014 Apr;69(4):343-7), expressing concern at this being a manikin study, and suggesting that the “vital issue” is whether a device is “fit for purpose” in the case of a drowning patient.

A reply

Lofgren B, Adelborg K. Anaesthesia 2014; 69(8): 929-30

A response to the two concerns raised by McKenna (Anaesthesia 2014; 69(8): 928) and Baker (Anaesthesia 2014; 69(8): 928-9), acknowledging that more studies are needed and that there is currently “insufficient evidence” to recommend any specific ventilation technique among lifeguards. They also reiterate their study conclusions.

Utility of the Aintree Intubation Catheter in fiberoptic tracheal intubation through the three types of intubating supraglottic airways: a manikin simulation study

Ueki R, Komasawa N, Nishimoto K, Sugi T, Hirose M, Kaminoh Y. J Anesth. 2014 Jun;28(3):363-7

Manikin trial comparing LMA Fastrach-Single Use, air-Q and I-gel with success rate of tracheal intubation, intubation time and collision with the glottis measured. Results suggest Fastrach took longer to intubate with a higher failure rate, and the Aintree Intubation Catheter reduces collisions.

The LMA-Supreme versus the I-gel in simulated difficult airway in children: a randomised study

Kus A, Gok CN, Hosten T, Gurkan Y, Solak M, Toker K. Eur J Anaesthesiol. 2014 May;31(5):280-4

In this double-blind study, the scenario was made more difficult by using a cervical collar. Primary aim was to compare leak pressures between devices, with success rate, insertion and fibreoptic view other parameters measured. First attempt success and leak pressure was higher with LMA Supreme. Both devices proved effective, and differences may not be clinically significant.

Is I-gel airway a better option to endotracheal tube airway for sevoflurane-fentanyl anesthesia during cardiac surgery?

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.
