Common causes of rhinorrhea in children are: 1. Acute febrile diseases: Some infectious diseases with rapid onset and high fever temperature, especially upper respiratory tract infections, can easily lead to acute congestion and swelling of the nasal mucosa, easily causing rupture and bleeding. Trauma trauma is also one of the common factors. The nose is exposed to the body surface, and children are more active, encounter impact, bruises, nose bear the brunt of the impact of external forces mucosal vessels rupture bleeding.
2, digging nostrils: digging nostrils is a common “small action” of children, fingers in the nasal cavity repeatedly digging, easy to damage a part called “Lai’s area”. This area is located in the front of the nasal cavity, below the front of the nasal septum, there are many blood vessels, and the nasal mucosa is thin, this location and physiological characteristics, the blood vessels in this area are prone to rupture, bleeding.
3, sinusitis: acute and chronic sinusitis, the mucous membrane in the nasal cavity or sinuses is congested and swollen, and under the stimulation of purulent nasal discharge, the blood vessels under the mucous membrane are prone to bleeding. Seasonal changes in the nasal cavity dry spring and autumn dry, the mucosa of the nasal area is also prone to dry, capillary toughness is not enough, digging nose, collision, etc. easily lead to blood vessel rupture bleeding.
4, hematological diseases: such as leukemia, thrombocytopenic purpura, aplastic anemia, etc., can directly cause nasal bleeding in children, and can cause repeated massive bleeding.
When a baby has a nosebleed, how to deal with it appropriately? The first thing is not to panic, let the child take slow deep breaths and relax, and then take appropriate measures to stop the bleeding. Put the child in a sitting or semi-sitting position, leaning forward slightly, and do not tilt the head, because the common site of nosebleeds in children is the above-mentioned “Lai’s area”. Pinch the upper end of the child’s nose with your index finger and thumb, push the bleeding side of the nose into the nasal septum, and compress for several minutes, usually 4-8 minutes.
After the above treatment, most children’s nosebleeds can be stopped. If this does not work, you should go to the hospital immediately. In addition, if nosebleeds occur regularly in children, it is prudent to consult an ENT and have blood tests performed to clarify the cause of nosebleeds as soon as possible.
