Comparison of oropharyngeal leak pressure between the Ambu® AuraGain™ and the LMA® Supreme™ supraglottic airways: a randomized-controlled trial

Purpose Studies comparing the recently introduced Ambu® AuraGain™ (Auragain) with the LMA® Supreme™ (Supreme) supraglottic airway (SGA) have reported conflicting results regarding differences in oropharyngeal leak pressure (OLP). This randomized-controlled trial investigated the OLP of the Auragain compared with the Supreme in patients undergoing ambulatory surgery.
