If a child has a nosebleed all the time, it is generally not abnormal. Because of the tenderness of the nasal mucous membrane, the distribution of capillaries on the nasal mucous membrane is relatively large, sometimes with the stimulation of the nasal mucous membrane, it is relatively easy to appear nosebleeds. Of course, through the examination of the Pentacenter, if this is clear, there is no need for special treatment. However, sometimes it is still necessary to check the platelet and coagulation function, there is no thrombocytopenia, to rule out whether there is a blood system disease. If we exclude the blood system disease, the general nosebleed is the case mentioned above, but there is no special need to deal with, at most, use some saline spray nose, or use some seawater to wash the nose, in this way, let the nasal mucous membrane a little bit more fluent, the nasal cavity a little bit more fluent, so as to reduce the irritation, the problem will not be too big.
