目的 为临床提供一种针对CO中毒有价值的辅助检查手段。方法 采用脑电地形图 (BEAM)对 82例CO中毒病人脑电活动进行研究 ,并将治疗前首次检查和经治疗后复检结果结合临床改变进行对比分析。结果 首检正常8例 (9 76 % ) ,异常 74例 (90 2 4% ) ;复检正常 5 6例 (6 8 2 9% ) ,异常 2 6例 (31 71% ) ,两者比较差异有非常显著意义 (P <0 0 1)。结论 BEAM结果对反映CO中毒程度、中毒后脑组织的功能状态、判断预后有较高的临床价值
Objective To provide a valuable tool for the clinical examination of CO poisoning. Methods 82 patients with CO poisoning were studied with electroencephalography (BEAM). EEG activity was compared between the first examination before treatment and the second after treatment. The results were compared with clinical changes. Results The first examination was normal in 8 cases (9 76%) and abnormality in 74 cases (90 2 4%). The recurrence was normal in 56 cases (682.9%) and abnormality in 26 cases (31 71%), There was a significant difference (P <0.01). Conclusions BEAM results have high clinical value to reflect the degree of CO poisoning, the functional status of brain tissue after poisoning, and prognosis
