Nostrils

Introduction The snot is also called the snot. It refers to the blood from the Qing dynasty. It is a common disease. Mainly due to the lungs, stomach, liver heat and heat, forced blood, so that the blood overflows the clear road, from the nostrils out of the nose, there are also a few caused by kidney deficiency or qi deficiency. The snot is also known as sputum. When the amount of nasal discharge is large, it is also called nasal sinus or nasal sputum. It is also a common nosebleed.

Cause

The reasons are complex and can be roughly divided into two categories:

(a) local causes

1. Trauma.

2. Pneumatic damage.

3. Nasal septum deviation: nasal septum perforation also often has nasal symptoms.

4. Inflammation:

1 non-specific inflammation: dry rhinitis, atrophic rhinitis, acute rhinitis, acute maxillary sinusitis, etc., often the cause of nosebleeds.

2 specific infection: nasal tuberculosis, nasal diphtheria, nasal syphilis, etc., due to mucosal ulceration, easy to cause nosebleeds.

5. Tumors.

6. Others: nasal foreign bodies, nasal leeches, can cause repeated massive bleeding. In the plateau area, due to low relative humidity, and suffering from dry rhinitis, it is an important cause of regional nosebleeds.

(two) systemic reasons

1. Blood disease:

1 platelet volume or qualitative abnormalities.

2 abnormalities in the coagulation mechanism.

2. Acute infectious diseases.

3. Cardiovascular disease:

1 arterial pressure is too high: such as hypertension, atherosclerosis, nephritis, eclampsia with hypertension.

2 increased venous pressure: such as mitral stenosis, chest or mediastinum and large neck mass, emphysema, pulmonary edema and bronchial pneumonia.

4. Vitamin deficiency: When vitamin C, K, P and trace element calcium are lacking, they are prone to nosebleeds.

5. Chemicals and drug poisoning: poisoning of phosphorus, mercury, arsenic, benzene, etc., can damage the function of the hematopoietic system and cause nasal discharge. Long-term use of salicylic acid drugs can cause a decrease in prothrombin and easy bleeding.

6. Endocrine disorders: Compensatory menstruation, auratic nosebleed often occur in puberty, mostly due to decreased estrogen content in the blood, caused by vasodilatation of the nasal mucosa.

7. Hereditary hemorrhagic telangiectasia, liver and kidney chronic diseases, rheumatic fever, etc., may also be associated with nosebleeds.

Endoscopic examination of fiberoptic nasopharyngoscopy

In general, nosebleeds caused by local diseases are mostly limited to one side of the nasal cavity, and those caused by systemic diseases may alternate or simultaneously bleed on both sides of the nasal cavity. Before the nose can not find the bleeding site, such as bleeding, after surgery, nasal or fiberoptic nasopharyngoscopy. Hemorrhage in the sinus, the blood often flows out from the nasal passages or olfactory. In addition to finding bleeding points, perform necessary systemic examinations (measure blood pressure, blood routine examination, bleeding time and clotting time measurement, capillary fragility test and platelet count, etc.). There is a fashion to consult with the relevant departments to find the cause.

Differential diagnosis

(1) unilateral snoring: hemorrhage on one side of the nose, found in trauma, nasal infection, local vascular injury, nasopharyngeal carcinoma, nasal septum deviation.

(2) bilateral snot: caused by systemic diseases, such as some febrile infections (epidemic hemorrhagic fever, typhoid fever, etc.), blood system diseases (thrombocytopenic purpura, aplastic anemia, leukemia, hemophilia) Disease), high blood pressure, liver and spleen disease, vitamin C or K deficiency.

Different ages of snoring disease:

(1) Pediatric: The child has a pus and bloody sputum on one side of the nostrils, and there is a foul odor, taking into account the foreign body in the nose. Because some children have the habit of incorporating soybeans, peanuts, buttons and other foreign objects into the nasal cavity.

(2) Youth: Adolescent women with periodic nasal discharge should consider endometriosis, that is, the menstruation of Chinese medicine (menstrual manifestations of nasal bleeding). A large number of nasal discharges in adolescence, to consider nasopharyngeal fibroids.

(3) middle-aged or older: middle-aged or more snot, can not forget nasopharyngeal cancer.

(4) Elderly: The snot of the elderly is mostly related to arteriosclerosis and hypertension. The elderly may have nasal discharge when the blood pressure rises rapidly, which may be regarded as a signal of a cerebrovascular accident (stroke). Since the nose is very common in daily life, it often does not attract people's attention. For the bleeding that is not bleeding, people often go to the hospital because of too much bleeding. For those who don't have a lot of bleeding or bloodshot in the nose, people tend to think that they are "getting angry" and ignore it, or take the heat and sputum. In fact, for bloody nose, especially the possibility of nasopharyngeal cancer. Nasopharyngeal carcinoma is one of the common cancers in China. Chinese people have five times the chance of developing nasopharyngeal cancer. This disease occurs mostly in adults, and its pathogenesis is related to genetic, viral, environmental and other factors. The early symptoms of nasopharyngeal carcinoma are: sucking blood or blowing nose, especially in the morning when you get up in the first nasal sputum with bloodshot or small blood clots, neck lumps, tinnitus, hearing loss, headache. Therefore, when a bloody nose occurs, a nasopharyngeal examination should be performed as soon as possible to confirm the diagnosis.
