老年急性一氧化碳中毒后迟发性脑病的脑电图分析

目的:探讨老年急性一氧化碳中毒后迟发性脑病(DEACMP)患者的脑电图(EEG)特征。方法:对54例老年DEACM患者进 行EEG检查,并与52例健康老年人对照。结果:两组EEG总异常率、额颞区局灶性异常率及α波平均频率比较,差异有显著性(P<0.001、 P<0.005及P<0.001),且EEG异常程度与痴呆程度呈正相关(r=0.488、P<0.001=0.000)。结论:EEG检查在老年DEACMP患者诊 断、疗效判定及预后评估方面有一定的价值。

An analysis of EEG in aged patients with delayed encephalopathy after acute carbon monoxide poisoning

Objective:To observe the characteristics of EEG in aged patients with delayed encephalopathy after acute carbon monoxide poisoning.Methods:EEG were determined in54aged patients with delayed encephalopathy after acute carbon monoxide poisoning and52healthy old people controls.Results:There was significantly difference among the total abnormal rate and rate and focus abnormal rate in the frontal part and temporal regions and average frequency of a wave between the two groups(P<0.001,P<0.005and P<0.001).And there were positive correlation between the abnormal degree of EEG and the degree of dementia.Conclusions:EEG has positive value in the diagnosis and in the judgementing the therapeutic effect and evaluating the prognosis of aged delayed encephalopathy after acute carbon monoxide poisoning.
