Coughing up blood is a common clinical symptom in patients with pulmonary tuberculosis. When coughing up a small amount of blood, patients should be comforted, eliminate tension, rest in bed, and be treated with hemostatic drugs such as aminohexanoic acid and phenolsulfonamide. In case of massive bleeding, posterior pituitary preparations can be used. If posterior pituitary preparations are not effective, surgical treatment can be chosen. If a patient with tuberculosis bleeds less than 100mL per day, it is considered a small amount of bleeding; if the bleeding is between 100-300mL per day, it is a moderate amount of bleeding; if the bleeding is over 300mL per day, it is considered a large amount of bleeding. The main cause of bleeding in patients with tuberculosis is the breakdown of small blood vessels after Mycobacterium tuberculosis invades the lung tissue. In case of damage to large blood vessels, surgery is required. Patients with tuberculosis can be cured with reasonable and regular anti-tuberculosis treatment, which is effective and has a good prognosis.
