目的 :采用药物定量脑电图方法判断静脉滴注尼莫通对 TIA病人脑功能的改善作用。方法 :在 3 0例TIA病人中进行静滴尼莫通 50 ml,比较治疗前后定量脑电图主频 ,θ、δ频段相对功率值的动态度化 ,并设对照组。结果 :两组治疗前后大部分脑区主频、θ、δ相对功率值 ,差异有显著性意义。治疗前与对照组比较 ,主频呈现慢波化(后移 ) ,θ、δ相对功率值明显升高 ,治疗后与治疗前比较主频大部分前移 ,θ、δ相对功率值明显下降。结论 :TIA病人定量脑电图显示慢波化趋势 ,存在明显的脑电生理变化 ,因此我们认为定量脑电图可作为判断尼莫通对 TIA病人疗效观察的指标之一
Objective: To determine the effect of intravenous drip of nimotop on the brain function of patients with TIA by using quantitative electroencephalogram (EEG) method. Methods: Thirty patients with TIA were intravenously injected with nimoton 50 ml. The dynamic changes of the main frequency, theta and delta frequencies of the quantitative electroencephalogram (EEG) were compared before and after treatment. The control group was also established. Results: Before and after treatment, the main frequency, θ, δ relative power values of most brain regions before and after treatment were significantly different. Compared with the control group before treatment, the main frequency showed a slow wave (backward), the relative power values of θ and δ were significantly increased, and the main frequency was mostly forward after treatment, the relative power values of θ and δ decreased significantly. Conclusion: The quantitative electroencephalogram of TIA patients shows the trend of slow wave and there is obvious electrophysiological changes. Therefore, we think that quantitative electroencephalogram can be used as one of the indicators to judge the effect of nimotop on TIA patients
