There are several factors that usually cause nosebleeds:
1, dry climate. The nasal mucosa is moist, so avoid dryness. No matter in the crisp autumn season or in the cold1February season, as long as the indoor and outdoor climate is dry, nosebleeds are prone to occur.
2, fever. When fever occurs, the heart rate increases, the blood flow rate is fast, and the small blood vessels dilate. In addition, when fever, less water intake, sweating more. In the case of dry mouth, it is easy to cause nosebleeds.
3. trauma. Digging nostrils by hand damages nasal mucosa, leading to blood vessel rupture; In nasal trauma, such as falls and bumps; There are foreign bodies in the nasal cavity; Or sometimes due to external forces such as coughing, sneezing and blowing your nose hard, it may damage the nasal mucosa and cause nosebleeds. Therefore, nosebleeds should be prevented according to the induced causes.
What should I do if I have a nosebleed?
Calm down first, immediately pinch both sides of the nose with your thumb and forefinger to the nasal septum, and then press to stop bleeding.
Second, head forward, face down, open your mouth and breathe, or lie down and raise your head. Never look up, it will make the blood swallow, and if you vomit too much, it will be mistaken for hematemesis.
Third, wet the towel with cold water and apply it to the root of the nose to make the blood vessels contract and stop bleeding when they are cold.
Fourth, use sterile cotton, gauze or toilet paper to block the bleeding site and press the broken blood vessel to stop bleeding. If the bleeding continues after the blockage, or the blood flows out of the mouth through the pharynx, you should go to the hospital for nasal emergency immediately, and you should not neglect it.
In addition, it should be noted that frequent nosebleeds may be a local problem of the nose or a manifestation of some disease. Therefore, people who often have nosebleeds should go to the hospital for further examination so as not to delay their illness.
Because I always have a nosebleed, I am experienced and have used:
Cold compress your forehead, or fill your nostrils with cold water.
Commonly known as "tooth picking" (local name, I don't know how to call it elsewhere), the water droplets squeezed out of the leaves of grass (with thorns around the leaves) are stuffed in the nose of cotton.
Put vinegar and Yunnan Baiyao in a cotton ball and stuff it in your nose.
Raise your right hand when the left nostril bleeds and raise your left hand when the right nostril bleeds.
The left and right middle fingers just hook together.
Pinch it on the blood vessels of the nose wing (where the nose meets the eyes) for 2 minutes.
These are all the methods I have used, but they don't feel particularly effective. But now I still think that the common misunderstanding of nosebleeds should be said, that is, don't look up. Looking up is useless for stopping bleeding.
Because I have been to the hospital because of nose bleeding (they use a hemostatic needle or cotton ball to drop chemicals, and then find a bleeding point to stop bleeding. Only using chemicals is very effective, but in the hospital, because the bleeding point is deep, cotton plugs the nostrils, but it is very effective. You said that cold compress is ineffective, so you might as well try the chemicals used to stop bleeding in the hospital. I don't remember the name, you can go to the hospital to ask.
Just don't look up, find the bleeding point in front of the mirror (if it's shallow, it's easy to find, if it's deep, it's not practical), and stop the bleeding with a cotton ball. This method is the fastest.
I think it is still relatively easy to use. The method with good effect and high feasibility is to press the blood vessels in the alar while pouring cold water into the nostril (hook your head slightly, pour cold water into the nostril to cool down, but it is not conducive to the healing of the broken blood vessels, pour it for a while, then plug it up, and then cold compress your forehead) (don't look up, tilt your head slightly, and stretch your nose forward to prevent clothes from being contaminated).
Nosebleed, also called nosebleed, is a symptom. There are two reasons for nosebleeds, one is systemic, such as hypertension, blood system diseases and vitamin deficiency. Hypertension is generally more common in adults and has a history of hypertension. Blood diseases often have bleeding spots and ecchymosis on the skin and oral mucosa, or there is bleeding. The other is the local causes of nasal cavity: trauma, tumor, special infectious diseases and so on. And women's compensatory menstruation. Trauma has a history of trauma, nose bleeding caused by tumor is mostly fixed on one side, and there are other symptoms such as nasal congestion. Specific infections include tuberculosis, syphilis, nasal induration, etc. These diseases are rare and should all have a past history.
The most common nosebleed is nosebleed caused by trunk of nose. This kind of bleeding is usually small and not fixed on one side, because the bleeding site is close to the front of the nasal cavity, so it is easy to stop bleeding, and it can stop bleeding by itself. This is because the blood vessels at the front end of the nasal cavity are shallow and the mucosa is dry, which is easy to cause rupture. If this is the case, it is recommended not to pick your nose as much as possible, keep your stool unobstructed and spend less effort. Before going to bed at night, apply chlortetracycline eye ointment to the nasal cavity and then apply hot compress. Take vitamin K, B2, vitamin C, etc. Oral, you can also eat Niuhuang Jiedu tablets. If this is not the case, it is recommended to go to the hospital for a specialist examination, a clear diagnosis and symptomatic treatment.
