急性脑梗死脑电图与临床观察

The clinical observation and the EEG of acute cerebral infarction

目的探讨脑电图（EEG）在急性脑梗死的辅助诊断及判断预后方面的意义。方法将106例急性脑梗死患者的脑电图、CT及临床资料进行对比分析。结果性脑梗死早期（〈24h）EEG异常率63．6％，CT异常率25％，两者比较差异有非常显著意义（P〈0．01）。随着病情发展，24h后CT阳性率88,4％，明显高于EEG异常率。结论EEG反映脑功能状况，对皮质缺血十分敏感，在评价急性脑梗死中有一定优势，特别是在急性脑梗死超早期诊断方面。EEG对脑梗死的病情演变和预后有预测价值。CT反映的是组织结构的状态。二者结合，为其诊断、治疗、预后评估提供客观依据。

Objective To discuss the significance of EEG in the auxiliary diagnosis and prognosis of a- cute cerebral infarction. Methods To analyze 106 cases of acute cerebral infarction in patients with EEG, CT and clinical data. Results Early acute cerebral infarction （ 〈 24 h） EEG abnormality rate of 63.6%, CT ab- normal rate of 25 %, difference was very significant （P 〈 0. 01 ）. As the disease development,24 h after the CT- positive rate was 88.4%, significantly higher than the rate of EEG abnormalities. Conclusion EEG reflects the state of brain function, very sensitive to the ischemic cortex, in the evaluation of acute cerebral infarction has cer- tain advantages, especially in the ultra-early period diagnosis of acute cerebral infarction area. EEG have predictive value in disease evolution and prognosis of cerebral infarction. CT are reflected in the state of the organiza- tional structure. Combination of both, provide an objective basis for cerebral infarction in diagnosis, treatment, prognosis.
