i-gel® from Intersurgical: clinical evidence listing

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

Does prewarming the i-gel supraglottic airway device fit the larynx better compared to keeping it at room temperature for non-paralysed, sedated patients: a randomised controlled trial

Komasawa N, Nishihara I, Tatsumi S, Minami T. BMJ Open. 2015 Jan 13;5(1):e006653

Patients were assigned to a warm (at 42 degrees centigrade) or control room temperature group. Number of attempts until successful insertion and sealing pressure were compared. Authors conclude that pre-warming did not increase insertion success rate.

The effects of prewarming the I-gel® on fitting to laryngeal structure

Nishiyama T, Kohno Y, Kim HJ, Shin WJ, Yang HS. The American Journal Of Emergency Medicine 2012; 30(9): 1756- 1759

180 patients were randomised into two equal groups, one for insertion of i-gel® at room temperature, the other at 37 degrees centigrade. Insertion time, number of insertion attempts, inspiratory and leak pressures, and leak fraction were compared. Report found no significant difference between the two groups.
