Since several years, there are reports from the USA about the esophageal obturator airway, a simple device for emergency ventilatory support in the unconscious patient. The simplicity of its use is of advantage and may easily be achieved by paramedics too (blind insertion into the esophagus without the need of a laryngoscope). The occlusion of the esophagus prevents gastric inflation as well as regurgitation, emesis and aspiration. In our studies in anesthetized patients, the device proved to be effective. Still, preference should be given to endotracheal intubation whenever feasible. Several modifications of the EOA are discussed as well as possible complications.
几年来，美国有关于食管阻塞气道的报道，这是一种用于无意识患者紧急通气支持的简单装置。其使用简单是一大优势，护理人员也能轻松操作（无需喉镜盲目插入食管）。食管阻塞可防止胃胀气以及反流、呕吐和误吸。在我们对麻醉患者的研究中，该装置被证明是有效的。不过，只要可行，仍应优先选择气管插管。文中还讨论了食管阻塞气道的几种改进方法以及可能出现的并发症。
