目的

分析动态脑电监测(AEEG)对急危重症脑血管病预后评估的作用和价值。

方法

选择30例在我院神经内科接受治疗的72 h内发病的急危重症脑血管病患者作为研究对象，对其进行AEEG监测，确定患者的EEG分级，并分析EEG分级与预后以及EEG分级的动态变化与预后，急危重症脑血管病患者的预后与相关因素之间关系使用Logistic回归进行分析。

结果

第1次EEG分级与预后具有良好的相关系，EEG分级越高显示患者预后越差；EEG的评分会随患者病情的变化而发生变化，第1次EEG分级为Ⅰa者，若持续分级为Ⅰa，则预后良好，若分级恶化，则预后较差；第1次分级为Ⅰb者，若分级持续为Ⅰb，则预后较差，若分级转变为Ⅰa，则预后良好；EEG分级为3级或以上的患者向更高分级发展，其预后极差。EEG分级预测患者生存率的准确率显著高于格拉斯哥-匹斯堡(GCS-P)评分(P＜0.05)。

结论

AEEG监测及其分级结果可以准确以及客观地反映出急危重症脑血管患者疾病的严重程度并能较好地对预后进行预测，准确率高，值得临床推广使用。

Objective

To analyze the role and prognostic evaluation value of dynamic electroencephalography monitoring on the critical cerebrovascular disease.

Methods

Thirty patients with critical cerebrovascular disease in 72 hours and accepting treatment in our hospital neurology were selected as research object.Conduct EEG monitoring and then identify the EEG grading.Then,we analyzed the correlativity between EEG grading and prognosis,EEG grading variation and prognosis,and between critical cerebrovascular disease patients'prognosis and relevant factors,Logistic regression analysis were be used.

Results

There is good relationship between the first EEG classification and prognosis,the higher grading show the patient would have worse prognosis.The EEG score would be changed by patient's changing condition.The first EEG grading identified to beⅠa,if that condition continue,so the prognosis would be good,if not,then the patient's condition would be bad.The first EEG grading identified to be 1b,if it is persistent,that show bad prognosis,if it changed toⅠa,that indicate a good prognosis.Paitients with EEG grading three or higher,abominable prognosis is inevitable.To predict the patient's survival rate,EEG grading is more preciser than GCS-P score cale(P<0.05).

Conclusion

AEEG monitor and grading could have a precisely and objectively reveal the order of severity of critical cerebrovascular disease,giving a good predicton to prognosis and having high accuration,it is worth to be wild used in clinical practise.
