分析61例结脑急性期的脑电图改变。正常范围脑电图24例(39.34%),异常脑电图37例(60.66%),其中边缘状态9例(14.75%),轻度异常8例(13.11%),中度异常15例(24.59%),重度异常5例(8.22%)异常脑电图的主要表现是弥漫性、持续性、散在性慢波和α波慢化。其异常率和异常程度与精神意识障碍呈正比关系,与颅内压增高不成正比。结脑急性期进行脑电图常规检查,有助于估价脑损伤的程度,对治疗预后的估计有极大的帮助 EEG changes in 61 cases of acute brain injury were analyzed. There were 24 cases (39.34%) of normal range electroencephalogram and 37 cases (60.66%) of abnormal electroencephalogram. There were 9 cases (14.75%) in marginal state, 8 cases (13.11%) in mild abnormality and 15 cases %), Severe abnormalities in 5 cases (8.22%) abnormal EEG the main manifestations of diffuse, persistent, scattered slow waves and slow wave α. The abnormal rate and abnormalities and mental disorders are in direct proportion to the increase in intracranial pressure is not proportional. Cerebral encephalitis in the acute phase of routine examination, will help assess the extent of brain injury, the prognosis of treatment is of great help to estimate
