急性一氧化碳中毒后迟发性脑病患者的脑电地形图分析

Analysis of Brain Electrical Activity Mapping(BEAM)in Patients with Delayed Encephalopathy after Acute Carbon Monoxide Poisoning(DEACMP).

目的 探讨脑电地形图 ( BEAM)对急性一氧化碳中毒后迟发性脑病 ( DEACMP)患者的应用价值。方法 对 40例DEACMP患者进行 BEAM检查。结果 BEAM异常率 1 0 0 % ,主要改变为 δ频带功率增高 (多在额颞区 ) ,θ频带功率减弱 ,其异常程度与痴呆程度基本一致。结论 BEAM可以反映 DEACMP患者的脑功能状况 。

Objective To explore the application value of BEAM in patients with DEACMP.Methods BEAM were determined in 40 patients with DEACMP.Results The abnormality rate of BEAM was 100%.The mainly showing the increase of δ and θ frequency band powers (mostly located on frontal and temporal regions)and the decrease of α frequency band powers.The abnormal degree of BEAMAND dementia was basically consistant.Conclusion BEAM might objectively evaluate the brain function of patients with DEACMP so as to provide evidence for evaluating the degress and the prognosis of DEACMP patients.
