We report an unusual case of ventilatory impediment caused by the obstruction of an endotracheal tube (ETT) by a nasogastric (NG) tube. A 72-year-old woman with bronchial asthma was scheduled for colostomy closure. An ETT of 7.5-mm internal diameter (ID) could not be advanced, and finally a 5.0-mm ID ETT was placed, because she had post-intubation tracheal stenosis. When an NG tube was inserted after endotracheal intubation, ventilation suddenly became nearly impossible. She was treated for an asthmatic attack, but her respiratory condition did not recover. We then exchanged the ETT for a laryngeal mask airway (LMA) and removed the NG tube. It was suspected that the cause of the airway obstruction was that the NG tube in the esophagus compressed the membranous portion of the stenotic trachea and the tip of the ETT was obstructed.
我们报告了一例不寻常的病例，即鼻胃管（NG）阻塞气管内导管（ETT）导致通气障碍。一名72岁的支气管哮喘女性计划进行结肠造口关闭术。由于她存在插管后气管狭窄，内径7.5毫米的ETT无法推进，最终置入了内径5.0毫米的ETT。气管插管后插入NG管时，通气突然几乎无法进行。她接受了哮喘发作的治疗，但呼吸状况未恢复。然后我们将ETT更换为喉罩气道（LMA）并取出了NG管。怀疑气道阻塞的原因是食管内的NG管压迫了狭窄气管的膜部，阻塞了ETT的尖端。
