Hemoptysis caused by violent coughing may be caused by rupture of small blood vessels caused by foreign bodies in the respiratory tract, pneumonia, tuberculosis, etc. It can be relieved by removing the causative factors, anti-infective drugs and anti-tuberculosis drugs. 1. Rupture of small blood vessels caused by foreign bodies in the respiratory tract: If there are foreign bodies inhaled in the trachea or bronchial tube, resulting in mechanical damage and inflammatory reaction of the respiratory epithelium, and violent coughing leads to the rupture of small blood vessels and the phenomenon of sputum with blood, clinically, we need to remove the foreign body first. 2. Pneumonia: after the lung tissue is infected, the local capillaries are congested and edematous, the permeability increases, and there can be exudation of erythrocytes or part of the patient causes the local capillaries to rupture when he coughs vigorously, thus hemoptysis occurs, which can be given active anti-infective treatment. For example, bacterial pneumonia is treated with antibiotics such as cefepime, and viral pneumonia is treated with drugs such as ribavirin. 3. Tuberculosis: frequent dry cough and hemoptysis are the main symptoms of tuberculosis. Blood in sputum may be related to the local inflammation caused by tuberculosis bacillus, which increases the permeability of capillaries or damages local small blood vessels. Hemoptysis may be related to the erosion of large blood vessels by TB lesions. It can be relieved by taking oral anti-tuberculosis drugs such as isoniazid, rifampicin, pyrazinamide tablets, and ethambutol hydrochloride tablets. In addition, there are many other causes of hemoptysis due to severe cough. If the patient has the symptoms of hemoptysis caused by severe cough, he should consult a doctor in time, after clarifying the cause of the disease, follow the doctor’s instructions to use medication or under the guidance of the doctor to adopt the appropriate treatment plan.
