I-gel (tm) vs. Auraonce (tm) laryngeal mask for general anaesthesia with controlled ventilation in paralyzed patients

Abstract

The i-gel (TM) and the AuraOnce (TM) laryngeal mask are supraglottic airway devices used for airway management during general anaesthesia. Both devices are cheap, disposable and widely used.

They may be used with both spontaneous and controlled ventilation. This study compared differences in the seal and peak pressures, and postoperative complications in these devices when used in paralyzed patients under controlled ventilation.
