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 ,为病情判断及预后评估提供依据
Objective To investigate the clinical value of BEAM in patients with delayed encephalopathy (DEACMP) after acute carbon monoxide poisoning. Methods 40 cases of DEACMP patients BEAM examination. Results The anomalous rate of BEAM was 100%. The main changes were the increase of power in δ band (mostly in frontotemporal area) and the decrease of power in θ band. The degree of abnormality was almost the same as that of dementia. Conclusion BEAM can reflect the status of brain function in patients with DEACMP and provide a basis for disease judgment and prognosis evaluation
