目的:探讨一氧化碳中毒迟发性脑病的脑电图、CT检查特征以及开始高压氧治疗次数与脑病的关系。方法:选取2010年7月~2013年6月期间在我院治疗的147例一氧化碳中毒患者为研究对象,采用脑电图和头颅CT检查,分析中毒程度、高压氧治疗次数与迟发性脑病的关系。结果:脑电图检查一氧化碳中毒迟发性脑病异常率为100%;CT检查一氧化碳中毒迟发性脑病异常率为77.78%;早期脑电图、CT检查结果异常与正常比较脑病的发生率高;开始高压氧治疗时间与一氧化碳中毒迟发性脑病大发生率有关。结论:一氧化碳中毒迟发性脑病大发生率与中毒程度、高压氧治疗次数有关;脑电图比CT敏感,CT特异性比脑电图好,脑电图适合指导疗程,CT有助于评定预后。
Objective: To investigate the characteristics of electroencephalogram (EEG) and CT examination of delayed encephalopathy after carbon monoxide poisoning and the relationship between the number of hyperbaric oxygen therapy and encephalopathy. Methods: A total of 147 patients with carbon monoxide poisoning who were treated in our hospital from July 2010 to June 2013 were enrolled in the study. EEG and CT were used to analyze the degree of poisoning, the number of hyperbaric oxygen therapy and the incidence of delayed encephalopathy relationship. Results: The abnormal rate of delayed encephalopathy after carbon monoxide poisoning was 100%. The abnormal rate of delayed encephalopathy after carbon monoxide poisoning by CT was 77.78%. The incidence of early EEG and CT abnormalities was higher than that of normal encephalopathy. The duration of hyperbaric oxygen therapy is associated with a high incidence of delayed encephalopathy after carbon monoxide poisoning. Conclusion: The incidence of delayed encephalopathy after carbon monoxide poisoning is related to the degree of poisoning and the number of hyperbaric oxygen therapy. EEG is more sensitive than CT, CT specificity is better than EEG, and EEG is suitable for guiding therapy. CT is helpful to evaluate prognosis .
