目的探讨脑电监测及脑电图(EEG)分级对重型颅脑损伤患者脑功能评价及判断预后的作用。方法对60例重型颅脑损伤患者行脑电监测并将EEG分级和格拉斯哥(GCS)评分、格拉斯哥预后(GOS)评分相结合判断患者脑功能变化和预后结果。结果60例重型颅脑损伤患者初次EEG检查全部异常。EEG分级与其对应的GCS评分成负相关(r=-0.795,P<0.01),EEG分级与其对应的GOS评分示亦成负相关(r为-0.583～-0.806,P均<0.01),初次EEG分级与其相应的GOS评分有显著相关性(P<0.01)。结论脑电监测及其EEG分级可从电生理学角度客观地评价重型颅脑损伤脑功能变化,判断患者预后。
Objective To investigate the effects of EEG monitoring and EEG grading on brain function and prognosis in patients with severe craniocerebral injury. Methods Sixty patients with severe craniocerebral injury underwent EEG monitoring and the EEG grading and Glasgow (GCS) scores and Glasgow prognosis (GOS) scores were combined to determine the changes of brain function and prognosis. Results 60 cases of severe head injury in patients with initial EEG examination all abnormal. EEG grading was negatively correlated with its corresponding GCS score (r = -0.795, P <0.01). EEG grading was also negatively correlated with its corresponding GOS score (r = -0.583-0.806, P <0.01) There was a significant correlation between grading and its corresponding GOS score (P <0.01). Conclusions EEG monitoring and its EEG grading can objectively evaluate the changes of brain function in severe craniocerebral injury from the electrophysiological point of view and judge the prognosis of patients.
