Supraglottic airway (SGA) devices provide effective conduits for oxygenation and ventilation and may offer protection from gastric aspiration. SGA devices are widely used by EMS clinicians as both rescue and primary airway management devices. While in common use for more than four decades, major developments in SGA education, science, and technology have influenced clinical strategies of SGA insertion and use in prehospital airway management for patients of all ages. NAEMSP recommends:SGAs have utility as a primary or secondary EMS airway intervention. EMS agencies should select SGA strategies that best suit available resources and local clinician skillset, as well as the nature of their clinical practice setting.EMS agencies that perform endotracheal intubation must also equip their clinicians with SGA devices and ensure adequate training and competence.In select situations, drug-assisted airway management may be used by properly credentialed EMS clinicians to facilitate SGA insertion.Confirmation of initial and continuous SGA placement using waveform capnography is strongly encouraged as a best practice.When it is functioning properly, EMS clinicians should refrain from converting an SGA to an endotracheal tube. The decision to convert an SGA to an endotracheal tube must consider the patient's condition, the effectiveness of SGA ventilations, and the clinical context and course of initial SGA insertionSGA training, competency, and clinical use must be continuously evaluated by EMS agencies using focused quality management programs.
声门上气道(SGA)装置可为氧合和通气提供有效的通道,并可防止胃内容物吸入。EMS 临床医生广泛将 SGA 装置用作抢救和主要气道管理装置。虽然 SGA 已经使用了四十多年,但在 SGA 教育、科学和技术方面的重大发展影响了各级患者的院前气道管理中 SGA 插入和使用的临床策略。NAEMSP 建议:SGA 可作为主要或次要的 EMS 气道干预措施使用。EMS 机构应选择最适合现有资源和当地临床医生技能以及其临床实践环境的 SGA 策略。进行气管插管的 EMS 机构还必须为其临床医生配备 SGA 设备,并确保进行充分的培训和获得相应的能力。在特定情况下,经过适当认证的 EMS 临床医生可以使用药物辅助气道管理来促进 SGA 插入。强烈鼓励使用波形二氧化碳描记法来确认初始和持续的 SGA 位置,这是最佳实践。当 SGA 设备功能正常时,EMS 临床医生应避免将其转换为气管内管。将 SGA 转换为气管内管的决定必须考虑患者的情况、SGA 通气的有效性以及初始 SGA 插入的临床情况和过程。EMS 机构必须使用重点质量管理计划不断评估 SGA 培训、能力和临床使用情况。
