[Esophageal obturator tube, a new method for emergency artificial respiration].

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.
