Symptoms of small foreign body in trachea

summary

Foreign body in respiratory tract is one of the common emergencies in life. If there is a history of foreign body inhalation, or suspected history of foreign body inhalation, although there is no sign, or X-ray examination is negative, or there is no obvious reason for bronchial obstruction, and long-term treatment of acute or chronic pneumonia and atelectasis patients should consider bronchoscopy, further definite diagnosis. If some foreign bodies are misdiagnosed, serious complications will occur, even life-threatening. Symptoms of small foreign body in trachea? Let's talk about it

Symptoms of small foreign body in trachea

The symptoms of foreign body were similar to those of laryngeal foreign body, mainly choking. Later, the active foreign body moves with the airflow, which can cause paroxysmal cough and dyspnea. At the end of expiration, the slapping sound of the foreign body impacting the tracheal wall and subglottic area can be heard in the trachea. The impact vibration of the foreign body can be felt under the thyroid cartilage. Because the trachea cavity is occupied by foreign bodies, or the subglottic edema is narrow, the respiratory tract is not completely blocked, the patient has serious dyspnea, and can cause wheezing. With the extension of time, due to respiratory secretions and other reasons (such as blockage expansion, etc.), incomplete blockage of respiratory tract can develop to complete blockage. The patient is characterized by inability to speak, extremely painful face and V-shaped hand, accompanied by severe cyanosis. If the foreign body is not discharged, the patient will be coma or even death.

The early symptoms were similar to those of tracheobronchial foreign bodies. Due to different types of foreign bodies can appear different symptoms. Plant foreign bodies, such as peas and peas, stimulate the mucous membrane greatly, and often have symptoms of acute bronchitis such as high fever, cough and purulent sputum. If it is a metal foreign body, it has less local stimulation. If it does not block, it can remain in the bronchus for several months without symptoms. Later, the foreign body embedded in the bronchus caused different degrees of obstruction and different symptoms.

When the bronchi are not completely obstructed, the trachea expands and the air can enter when inhaled. When exhaled, the bronchi shrink and the exhaled air is less, resulting in the continuous increase of the gas at the distal end of the obstruction and the formation of obstructive emphysema. During the examination, it was found that: (1) the chest movement of the affected side was limited during breathing; ② The respiratory sound of the affected side was decreased, the speech tremor was weakened, and the percussion was tympanic.
