重症脑血管疾病的脑电图改良分级标准研究

目的 比较脑电图(EEG)改良分级标准对脑血管疾病后脑功能损伤评价及预测预后的作用,为建立脑血管疾病的脑电图评估标准提供依据. 方法 对60例大脑半球病变的急性脑血管疾病患者进行EEG监测,并应用Synek标准和改良分级标准进行EEG分级分析.结果 两种标准的EEG分级与预后均有显著相关性(P<0.05),EEG级别越高,预后越差.经Logistic回归分析,改良标准生存、综合预测准确率更高,Synek标准低于改良标准.结论 应用改良标准进行的EEG分级能够较好地反映急性脑血管疾病后脑功能损伤的程度以及提高预测预后的准确性.

Revised grading standards of electroencephalography on evaluating severe cerebrovascular

Objective To evaluate the predicting accuracy of revised grading standards of electroencephalography (EEG) in cerebrovascular diseases. Methods EEG was performed on 60 patients suffering from acute cerebrovascular diseases (CVDs) in the hemisphere and the data were recorded continuously. According to 2 different grading standards of EEG (Synek standards and revised standards), these patients were graded, respectively. Results These 2 grading standards of EEG was statistically correlated with the outcome (P<0.05); the higher the EEG grade was, the poorer the outcome was. Logistic regression showed that the revised standards had higher accuracy on the survival and total prediction as compared with the Synek standards. Conclusion The revised grading standards of EEG can demonstrate the changes of CVDs well and improve the predicting accuracy.
