The decision on how to remove a foreign body in a child’s bronchus depends on the size, shape, and nature of the foreign body, as well as the location of the foreign body. If the location of the foreign body in the trachea is in the main bronchus, it can be removed quickly with a rigid bronchoscope. If the location of the foreign body in the bronchus is deeper and hard to reach by rigid bronchoscope, it needs to be removed by soft bronchoscope. If all operations fail, the tracheal foreign body needs to be removed under anesthesia with open heart surgery if necessary. Tracheal foreign bodies can cause asphyxia, which can be life-threatening at any time, and life-threatening at any time during the process of removing the bronchial foreign body, so the removal of tracheal foreign body needs to be carried out under the supervision of a doctor, ready to resuscitate.
