Abstract:
Objective To evaluate the values of amplitude-integrated electroencephalogram(aEEG) on the diagnosis of hypoxic ischemic encephalopathy(HIE),and the changes of aEEG in HIE with hypother-mia treatment.And to assess the therapeutic effect of hypothermia.Methods The changes of aEEG were continuously monitored before and after hypothermia treatment,and the proportions of various waveforms ap-pearing in aEEG were analyzed.Results A total of 90 cases were enrolled in this study,the changes of aEEG were monitored,including aEEG normal in 43 cases,mild abnormalities in 33 cases and severe abnor-malities in 14 cases.aEEG monitoring had a higher consistency with HIE grade and cranial MRI examination (Kappa ﹦0.584,P 〈0.001 ;Kappa ﹦0.590,P 〈0.001 ).The sensitivity,specificity,positive predictive val-ue,and negative predictive values of aEEG were high in predicting the severity of HIE.The index of with mild and severe abnormalities of aEEG was significant difference before and after the treatment of hypother-mia(P 〈0.05).Conclusion aEEG has a better evaluation effect on early diagnosis and severity assessing of HIE.Hypothermia can significantly reduce the proportion of abnormal aEEG after HIE,have a neuroprotective effect on the treatment of mild to moderate HIE.
