If we look at the clinical manifestations, in light cases of nasal bleeding, there is only blood in the snot, or there are crusted blood clots in the nasal cavity without blood outflow, or unilateral or bilateral nasal bleeding, there is only a small amount of blood dripping from the front nasal cavity, the bleeding time is short and sometimes it can be stopped naturally without treatment. In severe cases, the blood often flows like a stream, or the blood gushes out from the mouth and nose at the same time, and the bleeding lasts longer and is not easily stopped.
If the nasal mucosa damage, bleeding parts, roughly divided into the following four parts: 1, the anterior part of the nasal cavity bleeding: mostly nasal septum before the lower vascular intersection area bleeding, we call the Little area bleeding, is the most common bleeding parts of children, some children like to dig the nose, and can even directly damage the vascular plexus in the region, causing bleeding. The bleeding in this area is mostly characterized by a small amount of bleeding, short duration and easy to stop, but there are also some patients who need to be hospitalized for massive bleeding.
2.Hemorrhage in the middle and upper part of the nasal cavity: in children, it is mostly caused by trauma, often arterial bleeding, the bleeding is large and not easy to stop.
3, bleeding from the posterior part of the nasal cavity: commonly seen in the elderly. In children, it is sometimes seen as posterior nasal bleeding caused by nasopharyngeal fibrovascular tumor.
4.Diffuse nasal mucosal bleeding:It is mostly seen in children with systemic chronic diseases, such as leukemia and liver and kidney dysfunction; children with vitamin and nutritional disorders can also cause diffuse nasal bleeding.
