Children’s brain bleeding may be related to due to vitamin K deficiency, cerebral vascular malformation, intracranial tumors, hemophilia and other blood system diseases, etc., which can be treated by medication, surgical treatment and other ways. 1. Vitamin K deficiency: children due to vitamin K deficiency in the body, resulting in coagulation disorders, which leads to cerebral hemorrhage should be immediately injected with intravenous vitamin K₁, at the same time, intravenous transfusion of fresh blood, plasma or plasminogen complex, in order to rapidly replenish the coagulation factors, if necessary, follow the doctor’s orders to perform intracranial hematoma removal surgery. 2. Cerebral vascular malformation: refers to pediatric arteriovenous malformation, with bleeding as the first symptom, cerebral vascular rupture can occur in the brain, small amount of bleeding can be used to lower the cranial pressure, hemostatic drugs, to promote the absorption of the hematoma, such as mannitol injection, furosemide and so on. Angiography can also be performed to clarify the site of vascular malformation for embolization treatment, if the situation is urgent, craniotomy is required to remove intracranial hematoma. 3. Intracranial tumor: no matter it is primary or secondary tumor, it may cause cerebral hemorrhage when it violates blood vessels. At this time, it is necessary to firstly reduce intracranial pressure and stop bleeding, and then surgically remove the tumor if necessary; chemotherapy, radiotherapy or immunotherapy can also be carried out according to doctor’s instructions. 4. Hemophilia: hemorrhagic disease caused by hereditary coagulation factor deficiency, easy to induce intracranial hemorrhage after trauma, at this time need to transfuse fresh plasma or fresh frozen plasma, cold precipitation preparations and other supplemental coagulation factors, and can also be prescribed to use aminomethylcyclic acid and other drugs to protect the already formed blood clots. There are many other causes of pediatric cerebral hemorrhage, it is recommended that timely treatment to avoid delay.
