Moser B, et al. - Given that oropharyngeal leak pressure (OLP) is an important factor for successful use of supraglottic airway devices in general anaesthesia, researchers investigated whether the LMA Protector vs the LMA Supreme could develop a higher OLP, which could be of clinical relevance. They randomized 96 patients to the LMA Protector or LMA Supreme groups. Using a standardized cuff pressure at 60 cm H₂O, they measured OLP within 5 minutes after insertion of the supraglottic airway device. They also assessed insertion time of the supraglottic airway device, the number of attempts inserting the supraglottic airway device and the gastric tube, volume of gastric contents, and maximum airway pressure, as well as pulse oximetry throughout the operation. Following the removal of the supraglottic airway device, blood staining was determined. They also assessed postoperative airway morbidity 3 hours post-operation. A higher OLP was offered by the LMA Protector vs the LMA Supreme. This could be of significance in cases where a higher peak pressure is needed for sufficient supraglottic airway device ventilation.
