Tracheal stuck foreign body is also known as tracheal foreign body, and its clinical manifestations are related to the size of the foreign body, the location of the stuck trachea, the time of occurrence and other factors. When the foreign body is large and stuck in the upper bronchus, the patient can have obvious dyspnea, cyanosis, accompanied by choking cough, and in severe cases, asphyxiation and death can occur. If a small and smooth foreign body can be stuck in the lower bronchial tube, the patient mainly coughs, with obvious choking, chest tightness, shortness of breath, occasional chest pain, and when coughing violently, it can also be accompanied by blood in the sputum. In addition, a small number of patients with tracheal foreign bodies can enter the distal bronchus because the foreign body is particularly small and irritating. The symptoms of coughing may not be taken seriously at that time, but with the prolongation of time, obstructive pneumonia, lung atelectasis, and lung abscess formation may occur. In addition to coughing and sputum, the patient may also have different degrees of chills and fever. Therefore, when a foreign body occurs in the trachea, chest X-ray or CT examination should be carried out in a timely manner, and bronchoscopy should be carried out in a timely manner to search for and remove the foreign body.
