Children's nasal discharge blood

There is nothing wrong with a runny nose, but if you find that there is some blood in the runny nose, this will make people very worried, because in life most people think that nosebleeds are a very serious disease, especially many people often pick their noses due to trauma or surgery, and there are foreign objects in the nasal cavity. These are the reasons for the patient's nose bleeding, and further examination is needed to choose the appropriate method to confirm the diagnosis.

Causes of symptoms

1. Local causes

1. Idiopathic

2. Traumatic: due to local mechanical injury, such as nose picking, nose blowing, nasogastric feeding, foreign objects in the nasal cavity, etc. Skull base fracture causes rupture of the internal carotid artery (via nosebleed). Surgical trauma, such as maxillary sinus lavage, nasal biopsy, turbinate surgery, etc.

3. Inflammatory: acute rhinitis, acute sinusitis, dry rhinitis, atrophic rhinitis, erosion of nasal septum mucosa, stimulation of harmful chemical gases and specific infections, such as diphtheria. Hemorrhagic necrotic nasal polyps are a bleeding disorder that mimics a malignant tumor. Pathological examination can confirm it.

4. Nasal septum diseases: nasal septum deviation, perforation, etc.

5. Nasal and paranasal sinus tumors

(1) Benign tumors: nasal septum capillary hemangioma and nasal sinus hemangioma.

(2) Malignant tumors: malignant tumors of the nasal cavity and paranasal sinuses, malignant granulomas, etc.

6. Nasopharyngeal tumors: nasopharyngeal angiofibroma, nasopharyngeal carcinoma, etc.

2. Systemic causes

1. Blood diseases: leukemia, aplastic anemia, etc.

2. Hypertension and arteriosclerosis.

3. Increased venous pressure: emphysema, cor pulmonale.

4. Lack of vitamin E, K, B2, and P.

5. Poisoning: mercury, phosphorus, arsenic, and benzene poisoning.

6. Others: acute infectious diseases, endocrine disorders (ectopic menstruation), active rheumatic fever, uremia, sepsis, etc.
