Y1 - 2018 N1 - T2 - Reichman's Emergency Medicine Procedures, 3e AB - The term supraglottic airway (SGA) or supraglottic airway device (SAD) describes a heterogeneous group of airway devices that allow ventilation and oxygenation by sitting above the glottis. The first device of this kind was the laryngeal mask airway (LMA). SGAs are classified according to their characteristics into first-generation and second-generation devices. First-generation devices include the LMA Classic, LMA Unique, LMA ProSeal, LMA Supreme, and the first version of the Air-Q. Second-generation devices generally have an additional conduit for orogastric tube insertion and higher oropharyngeal leak pressures, and some of them allow SGA-guided fiberoptic intubation.1,2 SADs result in less cervical spine movement than traditional laryngoscopes.3 This can be useful for prehospital providers and the Emergency Department patient with potential cervical spine injury.
