Rhinorrhea is one of the most common diseases in childhood, and its causes include two categories: local and systemic. The bleeding site is mostly located in the front and lower part of the nasal septum in the area of the Richter’s area, where the blood vessels are gathered into a network, and the surface mucosa is thin, so it is easy to make the capillaries congested and dilated and bleed due to emotional fluctuations, fatigue, nostril digging, fever, upper respiratory tract infection and other triggers. In addition, most children have bad habits such as anorexia and partiality, if the intake of vitamin A, C, PP, etc. is insufficient, it can make the capillaries brittle and permeability increase easily to bleeding. Studies have shown that zinc deficiency of trace elements can also be an important cause of nosebleeds. Children with leukemia, hemophilia, aplastic anemia and other blood disorders may have nasal bleeding in addition to systemic bleeding signs. When a child has a nosebleed, parents can sit him/her up, tilt his/her head slightly upward, and press the thumb and forefinger on his/her bilateral ear flaps, which is just in the Lai area, and generally the bleeding can be stopped in 5-10 minutes. If the bleeding still does not stop at this time, ephedrine or 1‰ epinephrine solution can be dropped on cotton balls and sent into the nasal cavity, which has a hemostatic effect. To prevent nosebleeds in children, parents should first help correct the child’s bad habit of digging his nose, and actively prevent and treat rhinitis, sinusitis and other diseases. Usually, they should ensure normal rest for children and eat more fresh fruits and vegetables, such as tomatoes, celery, radish, lotus root, water chestnut, watermelon, snow pear, loquat, orange, tangerine, hawthorn, etc. Avoid eating more spicy and fried foods that cause “fire”. Children who are prone to nosebleeds can also use the following herbal dietary therapy: 1, fresh lotus root juice drink fresh lotus root washed, grinded and squeezed juice about; can clear the heat, cool the blood to stop bleeding. 2, yellow cauliflower lean meat soup yellow cauliflower (dried, soaked and washed), lean pork, honey dates, has the effect of clearing heat, calming the liver, moistening dryness, stop nosebleeds. 3.White foxglove root 30-60 grams of decoction to take. 4.Erythromycin or gentamycin ointment applied to the front of the nasal cavity.
