Encephalitis can be life-threatening if not detected in time, and many people believe that encephalitis can cause permanent damage to a child. The type of infection varies and so does the treatment. For children with fever, physical cooling is needed, and to reduce the severity of intracranial hypertension, mannitol and dehydration diuretics are given to reduce high cranial pressure, and for some children, hormones and immunoglobulin support drugs are needed, and the dosage is determined by the actual condition of the child. The dosage should be determined according to the actual situation of the child. For children with viral encephalitis, symptomatic treatment is needed to inhibit the replication of the virus in the body and to prevent the virus from penetrating into the cells and causing other complications. For bacterial encephalitis, treatment with sensitive antibiotics that can cross the blood-brain barrier is required, and treatment to prevent exacerbation of the infection is also essential. The above is a general treatment plan for children with encephalitis. The aim of treatment for children with encephalitis is early detection and early treatment. Not only is the treatment course shorter, but the harm to the child is also minimized. Each child has different symptoms, so it is important to find abnormalities and go to the hospital early.
