“…Notably, this study, which was published in 2019, is seldom cited, and we did not find any study or study protocol describing the analysis of this outcome in actual out-of-hospital cardiac arrest situations. While some might argue that no difference in carotid blood flow was found in anesthetized human patients when SGA devices were inserted [17], cardiac arrest is an entirely different condition and should therefore be analyzed, per se.…”

The Importance of Acknowledging an Intermediate Category of Airway Management Devices in the Prehospital Setting

Prehospital airway devices as often classified as either basic or advanced, with this latter category including both supraglottic airway (SGA) devices and instruments designed to perform endotracheal intubation (ETI). Therefore, many authors analyze the impact of SGA and ETI devices jointly. There are however fundamental differences between these instruments. Indeed, adequate airway protection can only be achieved through ETI, and SGA devices all have relatively low leak pressures which might compromise both oxygenation and ventilation when lung compliance is decreased. In addition, there is increasing evidence that SGA devices reduce carotid blood flow in case of cardiac arrest. Nevertheless, SGA devices might be particularly useful in the prehospital setting where many providers are not experienced enough to safely perform ETI. Compared to basic airway management (bag-valve-mask) devices, SGA devices enable better oxygenation, decrease the odds of aspiration, and allow for more reliable capnometric measurement by virtue of their enhanced airtightness. For all these reasons, we strongly believe that SGA devices should be categorized as “intermediate airway management devices” and be systematically analyzed separately from devices designed to perform ETI.
