一氧化碳中毒迟发性脑病高压氧治疗前后脑电图的改变

目的：探讨一氧化碳中毒迟发性脑病（DEACMP）患者高压氧治疗对脑电图改变的意义。方法：对46例急性一氧化碳中毒迟发性脑病患者进行高压氧治疗，治疗前后检查脑电图，并对其中34例患者进行长谷川痴呆量表检测和临床疗效观察。结果：治疗后脑电图和痴呆症状与治疗前比较均有明显改善（P＜0．01）。治疗后临床症状改善总有效率为82．6％，并且临床症状改善与脑电图改善相平行。结论：高压氧对治疗DEACMP有明显疗效；脑电图对该病的病情和疗效判断具有重要意义。

The Changes of Electroencephalograms Following Treatment of Retarded Brain Trouble Caused by Acute Toxicosis of Carbon Monoxide with Hyperbaric Oxygen

Objective: To investigate the implication of the changes of electroencephalograms following treatment of retarded brain trouble caused by acute toxicosis of carbon monoxide with hyperbaric oxygen. Methods: Forty six cases of retarded brain trouble caused by acute toxicosis of carbon monoxide were treated with hyperbaric oxygen. Through testing the electroencephalograms before and after the treatment and testing the H.D.S of 34 cases out of them, clinical curative effects were observed. Results: The electroencephalograms showed distinct progress after the treatment ( P < 0.01 ). The dementia symptoms were also relieved ( P < 0.01 ). Conclusion: Hyperbaric oxygen treatment has distinct curative effect to retarded brain trouble caused by acute toxicosis of carbon monoxide. Electroencephalograms are of great significance for the judgement of curative effect and prognosis of these patients.
