The esophageal obturator airway, in lieu of placement of an endotracheal tube, has been found to be an effective and reliably safe means of providing an artificial airway. By occluding the esophagus, it prevents gastric dilatation and aspiration. However, it is not totally without hazard. Two cases of pharyngoesophageal trauma are reported: a high esophageal tear found at post mortem examination and a pyriform sinus laceration noted on admission to the hospital. The authors recommend conservative treatment for cervical esophageal perforations and surgery for thoracic esophageal perforations. Despite these complications, the authors feel the esophageal obturator airway is safe and effective for use by those unskilled in direct endotracheal intubation when participating in cardiopulmonary resuscitation.
已发现食管阻塞气道可作为放置气管内导管的替代方法,是建立人工气道的一种有效且可靠安全的手段。通过阻塞食管,可防止胃扩张和误吸。然而,它并非完全没有风险。本文报告了两例咽食管创伤病例:一例是尸检时发现的高位食管撕裂伤,另一例是入院时发现的梨状窝撕裂伤。作者建议对颈部食管穿孔采用保守治疗,对胸部食管穿孔采用手术治疗。尽管有这些并发症,但作者认为,对于那些不熟练直接气管插管的人员,在参与心肺复苏时,食管阻塞气道是安全有效的。
