Bleeding from the nose is a common occurrence. It is a symptom of a disease, not a separate disease, because many diseases can have nosebleeds. The causes of nosebleeds are basically divided into two categories: 1, systemic causes, 1 , such as blood diseases: (like leukemia, hemophilia, thrombocytopenia, purpura, DIC (diffuse intravascular coagulation); 2, advanced stages of disease: (advanced cirrhosis, liver cancer; advanced chronic nephritis, renal failure, etc.); 3, hypertension, arteriosclerosis, old slow gas (chronic bronchitis in the elderly): cause pulmonary heart disease, so that jugular venous hypertension, etc. In short, anything that affects the body’s hematopoietic and coagulation functions, and increases the vascular (whether arterial or venous) pressure will cause rhinorrhea. Second, the nose local causes: 1, trauma: this is the most common cause; 2, tumors: whether benign (such as bleeding nasal polyps, papilloma) or malignant (such as nasopharyngeal carcinoma, malignant granuloma); 3, inflammation: common chronic rhinitis, sinusitis, atrophic rhinitis; 4, fever: caused by dry mucosa, or their own nasal mucosa on dry, picking nose and other reasons. Nose bleeding, although often occurring, but improperly handled, not only patients suffer, and can be dangerous, and therefore still need to be taken seriously. Before proceeding to deal with, first of all, we must judge that nose is the real bleeding, generally speaking, that nose first see blood, that nose is the real bleeding nostrils, because the general patients bleeding, a nervous blinded, especially out of the ground quickly and a large amount, it is not clear. This is very important because bleeding from the front end is easier to handle, while the back end is more complicated and relatively dangerous and should be taken seriously. According to my experience, I have summed up a few jargon, whether it is the patient or the family and the doctor, I hope to follow this principle: 1, calm and comfortable, with a clear mind. (Whether the patient, family members, and the doctor, no one should shout, creating a tense atmosphere) because this will make the patient more nervous, and therefore blood pressure will be more elevated, and secrete adrenaline and catecholamines, so that blood pressure further increase, making the bleeding more serious) 2, check the local, systemic balance. (That is, try to find out the site of bleeding, find out the site of bleeding, the treatment is very sure, and very simple. Systemic balance is not to focus on the local stop bleeding and ignore the general condition of the patient, especially patients with systemic diseases and elderly patients, otherwise the nasal bleeding is stopped, but the patient has a big problem, or even an irreversible situation). 3, urgent is to treat the symptoms, slow is to treat the root cause, not urgent or slow, both the symptoms and the root cause. (The condition is urgent, bleeding, the condition does not allow to check the bleeding site, seize the time, the simplest way to stop the bleeding first, such as filling method, and when the condition allows further comprehensive treatment.
