There are many reasons for children’s colds and nosebleeds, mainly due to frequent daily rubbing of the nose, or the nasal mucosa is dry. In addition, children because of the small blood vessels in the nose is dense into a network, fragile and sensitive, to become the anatomical factors of children’s cold and nosebleed.1, rubbing the nose: due to the children’s cold, the nasal mucosa began to appear congested and swollen, at this time, if you often go to picking the nose or rubbing the nose, it will lead to the destruction of the local capillary, so as to appear in the case of cold and nosebleed; 2, the nasal mucosa is dry: because the children in the time of cold and flu, poor physique, easy to fire, resulting in local dryness of nasal mucosa, bleeding. Poor physical condition, easy to fire, resulting in localized dryness of the nasal mucosa, bleeding, it is recommended to drink more water, eat some cool food, such as watermelon, green beans, etc.; 3, anatomical factors: there is a layer of septum on both sides of the nasal cavity and in the middle of the nostrils, which will have several pairs of blood vessels converging with each other. Especially in the nasal septum below the front of the nasal vestibule area, small blood vessels dense network, only a layer of very delicate mucous membrane protection, more sensitive, fragile. When a cold is accompanied by frequent sneezing, runny nose and other symptoms, small blood vessels are prone to rupture and bleeding, which is the anatomical reason why children’s nasal cavity bleeds easily when they have a cold. Parents should not be alarmed when children have a cold with nosebleeds, and should first reassure the child so that his or her emotions are calmed and he or she is not nervous. At the same time, do not let the child lie down, tilt his head back, should sit upright, head slightly forward, with the thumb and forefinger pressure on both sides of the nose softer place, usually need to be pressed for about 10 minutes. Wet, wrung-out towels can also be applied to the child’s forehead and the base of the bridge of the nose to constrict the local capillaries and slow down the bleeding. If the bleeding is heavy and pressure does not stop the bleeding, a wet cotton ball dipped in cold water can be inserted into the nostrils and then pressed. If the bleeding still does not stop, you need to go to the hospital for nasal filling.
