摘要：目的：探讨急性一氧化碳中毒与脑电图异常，进行高压氧治疗下，多数治愈出院，少数重型患者，因并发有不同程度合并症而死亡。方法: 50例年龄8～70岁急性一氧化碳中毒患者86份脑电图。结果：脑电图主要特征为广泛性不规则高波幅慢活动(δ、θ)连续性出现，以额、中央、颞区占优势，严重者可呈平坦波及爆发-抑制波。患者意识状态分为清醒、混浊 、昏迷，脑电图结果分别是轻、中、重度异常。结论：急性一氧化碳中毒患者，由于血中出现高浓度碳氧血红蛋白所致的低氧症和脑组织缺氧，以脑皮层及苍白球等基底受累最重(变性，软化或坏死)，并可有脑血管痉挛，出血，脑水肿等改变，而导致脑电图异常。

    Abstract： Objective： Inquiries into the impatient carbon monoxide poisoning and the electroencephalogram abnormalities, carrying on the hyperbaric oxygen, HBO treatment next, the most cures the hospital discharge, a handful of sufferer, die because of erupt the different degree to merge the disease. Methods： Impatient 86 electroencephalograms of carbon monoxide poisoning sufferer of 50 ages of 8～70 years old . Results： Cardinal feature of electroencephalogram for extensive the one who abnormality a slow activety (δ、θ) consecution appear, with frontal, central, temporal region gain advantage, serious can present the flat spread blow – depression, inhibition wave.Sufferer the meaning appearance is divided into awake, turbid , coma, the electroencephalogram effect is an abnormality respectively. Conclusion： Impatient carbon monoxide poisoning , because appearing the hypoxemia, mionectic blood and tapetums that high carboxyhemoglobin of concentration go to organiz the anoxia in the hem, implicating with the bases, such as cortex of tapetum and globus pallidus'etc. the most heavy( transformation, malacia or necrosis),and can have the changes, such as cerebral spasm, hemorrhage, bleeding and cerebral edema'etc, but cause the electroencephalogram excrescent. ......
