A 7-year-old girl presented to the emergency room (ER) with alleged history of aspiration of a toy magnet. The challenge was to safely extract the foreign body. A bronchoscopic approach with forceps, or Dormia basket, or Fogarty catheter, was considered, but these approaches had disadvantages, such as slipping or impaction of the object, and oxygen desaturation. Applying principles of removal of intraocular metallic objects in ophthalmologic surgery using magnetism, the object was removed with the help of another larger surface magnet. The location of the foreign body was confirmed by bronchoscopy. A Fogarty catheter was introduced distal to the object, under bronchoscopic guidance. A strong surface magnet was then placed on the surface of the chest and under C-arm guidance, the object was moved from the bronchus to the trachea. Once at the vocal cords, the Fogarty catheter was inflated to prevent it from slipping back and the magnet was extracted using forceps.
一名7岁女孩因据称误吞玩具磁铁而被送往急诊室。面临的挑战是安全取出异物。曾考虑使用支气管镜用钳子、多尔米亚篮或福格蒂导管的方法，但这些方法存在缺点，如物体滑落或嵌顿以及氧饱和度下降。应用眼科手术中利用磁性取出眼内金属物体的原理，借助另一个更大表面的磁铁取出了该物体。通过支气管镜确认了异物的位置。在支气管镜引导下，将福格蒂导管插入异物远端。然后在胸部表面放置一块强力表面磁铁，并在C形臂引导下，将异物从支气管移至气管。一旦异物到达声带，将福格蒂导管充气以防止其滑回，并用钳子取出磁铁。
