(2) Hematoma in the operation area of the neck compresses the trachea;

(3) Sore throat and neck braking affect the discharge of respiratory secretions;

(4) Surgery of the spinal cord can cause spinal cord edema or spinal nerve root edema, causing paralysis of the respiratory muscles and causing central dyspnea. Therefore, the patient's respiratory frequency, rhythm and complexion should be closely observed after surgery, and respiratory secretions should be regularly aspirated if necessary.
