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.
