【Objective】 To analyze the clinical characteristics of severe cerebral trauma in children and pertinent treatment. 【Method】 The influences of various risk factors on the prognosis were analyzed by statistics. 【Results】 Among the 45 children with severe cerebral trauma,6(13.33%)died.The degree of primary trauma influced the prognosis.32 patients with GCS between 5 and 8 survival,the survival rate was 71.11%,whereas 7 patients with GCS lower than 5 survived, the survival rate was 15.56%.Diffuse cerebral swelling and cerebral edema after trauma was an major risk factor influencing the prognoses. 【Conclusion】 After craniocerebral injury childrens tolerance on intracranial hypertension is poor and the change of the patients condition is rapid.Close observation of mind,pupil and GCS scoring and dynamic observation of CT is key to judge the injury condition.During treatment,ICP monitoring has important clinical significance.
