Why is it easy for children to have nosebleed? What should we do with nosebleed? When human organs bleed, we usually can't see it personally, but nosebleed is easy to be found. According to the analysis, the causes of children's epistaxis are as follows:
Acute febrile infectious diseases often occur in children with acute onset and high fever, especially upper respiratory tract infection. When high fever occurs, the blood vessels of skin and mucous membrane of the whole body become congested and swollen, and the same pathological change occurs in the nasal mucosa. Acute congestion and swelling of the nasal mucosa are more likely to cause rupture and bleeding, because the hail vessels of nasal mucosa are superficial. Once severe fever occurs, and the external force of blowing nose, the submucosal blood vessels will rupture and bleed.
Traumatic nose is an organ exposed on the body surface. Once trauma occurs, such as strike injury and fall injury, the nose naturally bears the brunt. Under the impact of severe trauma, submucosal blood vessels will rupture and bleed.
Strictly speaking, nasal excavation should also be included in the scope of trauma. Out of curiosity and discomfort, children often like to dig blindly in the nasal cavity with their fingers, which is not hygienic and easy to cause local mucosal bleeding in the nasal cavity. Generally, the part of nose digging is in the anterior and lower part of nasal septum. There are many blood vessels in this part. Many tiny blood vessels interweave into a plexus network, just like a spider web. The blood vessels are shallow and very thin. The part is in the mouth of nasal cavity. As long as you dig with your hand, you can break the blood vessels. More than 90% of children's epistaxis is located here.
Nasal foreign bodies usually, in addition to some secretion of nasal mucus, there is no object blocking the nasal cavity, so that breathing free and smooth. But sometimes, because of the fun, children like to put some small objects in their nose, such as peanut kernels, melon seeds, nuts, soybeans, plastic paper, metal toys and so on. Once these objects are stuffed into the nose and become foreign bodies, the child can't take them out by himself, and dare not make any noise. As time goes on, they will be forgotten and left in the nasal cavity. Some foreign bodies in the nasal cavity swelling, moldy, causing nasal mucosa infection, erosion and bleeding, sometimes in the adverse stimulation of foreign bodies, nasal mucosa can also cause traumatic bleeding.
Hemagglutination is determined by some special factors in the blood vessels of the human body. If under the action of some factors, some factors in the blood will have a series of changes, making the blood vessels and blood after bleeding,
These diseases include leukaemia, hemophilia, thrombocytopenic purpura, aplastic anemia and so on, which are collectively referred to as blood glass. This is the direct cause of children's epistaxis, and can cause repeated and massive bleeding.
Children with rhinitis and paranasal sinusitis 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 is congested and swollen, and mucopurulent nasal discharge occurs from time to time. Under the stimulation of purulent nasal discharge, submucosal blood vessels will also bleed.
To prevent children's nosebleed, we should take corresponding measures according to the specific reasons, such as actively treating acute febrile diseases, admonishing and educating children not to put things in the nose, changing the bad habit of digging the nose, eating less endothermic food, cooperating with doctors to treat nasal cavity and paranasal sinusitis, etc.
After reading the above contents, we should have some understanding of why children are prone to nosebleeds and what to do with nosebleeds. Today we will introduce more topics about ear, nose and throat health. Sihai Xiaobian will continue to introduce them in the following articles. Welcome to check.
