脑电图预测急性CO中毒后迟发性脑病研究

目的探讨急性CO中毒后迟发性脑病(DEACMP)的脑电图(EEG)演变规律与临床症状的关系。方法对136例急性CO中毒患者进行EEG跟踪检查,首次EEG检查均在中毒后48 h内完成。结果136例急性CO中毒患者共行EEG检查360次,其中异常EEG140例次(38.89%),EEG的异常程度与临床症状严重程度呈正相关。首次EEG有异常改变者43例,其中31例(72.09%)最终发生了DEACMP。第二次EEG仍有异常改变者30例,其中24例(80%)最终发生了DEACMP。结论EEG可预测DEACMP,急性CO中毒患者经抢救即使中毒症状已缓解或消失,只要EEG仍有异常改变就不应终止治疗。

EEG Predicting the Occurrence of Delayed Encephalopathy after Acute CO Poisoning

Objective To investigate the correlation between the electroencephalogram(EEG) changes and the clinical symptoms of patients with delayed encephalopathy after acute CO poisoning(DEACMP)to aid the prognosis of the disease by EEG.Methods One hundred and thirty-six patients with acute CO poisoning were checked by EEG in different times,and the first EEG test was performed in 48 h after the accident.Results Three hundred and sixty EEGs were done in 136 patients with acute CO poisoning.Abnormality rate in EEG was 38.89%(140/360) in this group of acute CO poisoning patients.There were positive correlation between the abnormal degree of EEG and the clinical symptoms,31 of 43 patients(72.09%) whose first EEG test were abnormal suffered DEACMP at the end,24 patients with acute CO poisoning out of 30 cases(80%) whose second EEG test were still abnormal suffered DEACMP at the end.Conclusions We can predict the occurrence of DEACMP by EEG,even the clinical symptoms of acute CO poisoning are disappeared the treatment should not be stopped.
