Four cases of esophageal rupture associated with the use of the esophageal obturator airway are presented and added to the fifteen cases already in the literature. The incidence of this complication may be greater than previously suspected since a systematic search for this complication has not been made in cardiac arrest patients. The mechanism of rupture of the occluded esophagus may be similar to that seen in postemetic rupture. Endotracheal intubation remains the procedure of choice in airway control of cardiac arrest patients, although the modified esophageal obturator airway with gastric tube may prevent the occurrence of esophageal rupture by allowing decompression of the esophagus.
本文报告了4例与使用食管阻塞气道相关的食管破裂病例，并将其补充到文献中已有的15例病例中。由于尚未对心脏骤停患者进行该并发症的系统筛查，因此该并发症的发生率可能比之前怀疑的要高。阻塞食管破裂的机制可能与呕吐后破裂所见机制相似。气管插管仍然是心脏骤停患者气道控制的首选方法，尽管带有胃管的改良食管阻塞气道可通过使食管减压来预防食管破裂的发生。
