Coughing with blood clots, clinically this symptom is called hemoptysis, that is, the blood comes from the part below the throat and is discharged through coughing, and the amount of blood is relatively large, which indicates that the source of blood and bronchial tube is very likely, for example, bronchial tube dilatation, pulmonary tuberculosis, which can cause the symptom of coughing with blood clots. Bronchopulmonary cancer can also cause coughing with blood clots, therefore, the corresponding examination should be improved in time for clarification, first of all, the lung CT should be improved in time for investigation, and at the same time, actively give the treatment of stopping hemorrhage, for example, use of phenol-sulfonyl ethylamine or posterior pituitary hormone, and also give the corresponding cough expectorant drugs, such as aminobromine hydrochloride and acetylcysteine, etc. If the examination is not successful, it will be difficult for the patient to find out the source of the blood. If the lung CT examination is not clear, further bronchoscopy is needed to clarify.
