In autumn and winter, many people will have nosebleed, which is mostly caused by the dry weather, but some children will have nosebleed inexplicably, and even in their sleep dreams, nosebleed will be left out, which makes the majority of parents worried. What causes nosebleed? How can children often have nosebleed prevented?
1. The climate is cold and dry
The reason why the nose is more prone to bleeding in cold and dry seasons is mainly because in cold weather, we like to eat some hot food. When we eat, hot air will accelerate the blood flow in the nasal cavity. If the nasal mucosa is thin or has been injured, it is easy to bleed. In addition, in the cold and dry environment, we need more blood to flow through the nasal cavity to improve the temperature and humidity. Therefore, the micro blood vessels of the nasal mucosa are easy to be congested, resulting in nosebleed.
2. Bad habits
Children are lively and active. They often hurt their nose unintentionally. The nose is an organ exposed on the body surface. Once there is an injury, such as a blow injury or a fall injury, the nose will bear the brunt naturally. Under the impact of severe trauma, submucosal blood vessels will rupture and bleed.
Strictly speaking, nose digging should also be included in the scope of trauma. Out of curiosity and suffering, children often like to dig blindly in the nasal cavity with their fingers, which is not healthy, but also easy to cause local mucosal bleeding in the nasal cavity. Generally, the part of nose digging is in the front and lower part of the nasal septum, and there are many blood vessels in this part. Many small blood vessels are interwoven into a network, which is still like a spider's web. The blood vessels are both superficial and very thin, and the part is at the mouth of the nasal cavity. As long as you dig with your hand, you can dig and break the blood vessels. More than 90% of children's epistaxis is here.
3. Lung fever caused by burning
The nose belongs to the lung orifices, and there are diseases in the nose. Generally speaking, there is a great relationship between the nose and the abnormalities in the lung, liver and other parts. When one's Qi and blood rise, especially when the lung qi is hot, one will have nosebleed. Therefore, in the daily diet, we should pay attention to clearing away heat and reducing fire, eat less spicy food, and try to avoid the occurrence of lung heat.
4. Tired Sports
Light nosebleed is also related to tiredness and sports. In general, these bleeding symptoms can be stopped by patients themselves. However, there is no sign that people with sudden nosebleeds had better go to the hospital for a check-up, and eliminate diseases such as nasal tumors as soon as possible.
5. Acute febrile diseases
Children often have some infectious diseases with acute onset and high fever, especially upper respiratory tract infection. When high fever occurs, the blood vessels of the skin and mucous membrane of the whole body will be congested and swollen. This pathological change also occurs in the nasal mucosa. The acute congestion and swelling of the nasal mucosa are more likely to cause rupture and bleeding. Because the hailblood vessels of the nasal mucosa are superficial. Once the severe fever occurs, and the external force of blowing the nose forcefully, the submucosal blood vessels will rupture and bleed.
6. Foreign body in nose
Usually, in addition to some secretion of the nasal mucus, there is no object blocking the nasal cavity, so that the breathing is free and smooth. But sometimes, children like to put some small objects in their noses for fun, such as peanut, melon seeds, nuts, soybeans, plastic paper, small metal toys, etc.
Once these objects are stuffed into the nose and become foreign bodies, the child can't take them out and dare not speak. After a long time, they are forgotten and left in the nasal cavity. Some foreign bodies in the nasal cavity with water swelling, mildew, causing nasal mucosa infection, erosion and bleeding, sometimes under the adverse stimulation of foreign bodies, the nasal mucosa will also cause traumatic bleeding.
7. Have blood diseases
The blood in human blood vessels should be neither bleeding nor agglutinating, which is determined by some special factors in the blood. If under the action of some factors, some factors in the blood will have a series of changes, making the blood vessels and blood in the event of bleeding, it is not easy to agglutinate and stop these diseases, such as white blood and hemophilia and thrombocytopenic purpura, aplastic anemia, etc., collectively referred to as blood glass, which is the direct cause of children's epistaxis, and will cause repeated and massive bleeding.
8. Rhinitis and paranasal sinusitis
Children are also prone to acute, chronic rhinitis and paranasal sinusitis. Once this kind of inflammation occurs, the mucous membrane in the nasal cavity or paranasal sinuses will be congested and swollen, and the mucopurulent snot will be discharged from time to time. Under the stimulation of the purulent snot, the blood vessels under the mucous membrane will also bleed.
How do children often have nosebleed
1. Before bleeding, try to blow the clot. Blow your nose, parents with their hands slightly pinched the child's nose, can also stop bleeding.
2. Fill with gauze or wet cotton. Put a small piece of sterilized wet gauze in each nostril, and some experts prefer to wet cotton with white vinegar. The acetic acid in the vinegar burns slightly. However, decongestant can only provide temporary hemostasis, so it is recommended not to abuse it, because it may damage the nasal membrane.
3. After blowing nose blood (removing blood clots) and stuffing cotton, squeeze the nostrils together with thumb and index finger, and keep pressing for 5-7 minutes. If the bleeding is still not stopped, repeat the action of stuffing cotton and pinching nose, and keep pressing for 5-7 minutes.
4. Having the child lie down or head up will cause blood to flow to the throat. You can sit in a chair and lean forward (don't lean your head back).
5. Cold compress with ice. Cold can cause blood vessels to contract and reduce bleeding. Cold compress nose, neck and cheek with crushed ice or ice towel.
6. When nasal blood is under control, apply some vitamin E ointment to the nose. If there is no vitamin E, it can be replaced by a little antibiotic or steroid ointment, which can be applied 2-3 times a day.
