摘　　要：目的:对33例一氧化碳中毒患者,经高压氧(HBO)治疗前后的脑电图(EEG)及脑电地形图(BEAM)进行无创伤性检查分析。方法:系统分析了33例HBO治疗CO中毒的患者EEG及BEAM的前后变化规律。结果:其EEG的阳性率为63.6%,BEAM的阳性率为87.8%。经HBO治疗后EEG所见背景的脑波基本变快,呈α慢节律,波幅略增高,δ、θ波活动基本消失,转为α节律,其阳性率为27.2%。BEAM各部位的弥漫性或局限性功率值降低,其阳性率为30.2%。结论:HBO治疗后能改善脑缺氧,脑水肿,提高血氧含量,处进患者苏醒,提高治愈显效率,减少后遗症发生。Objective EEG and BEAM were analyzed during the HBO treatment. Method We assessed characteristics of EEG and BEAM in 33 CO poisoning patients before and after the treatment with DYD- 2000 type equipment by HBO. Results EEG before treatment appeared extensive δ wave and θ wave, especially in frontal Cobe, parietal Cobe and temporal Cobe. BEAM appeared the power of diffuse or local slow wave （ δ or θ wave ） raising especially in frontal local slow wave （ δ or θwave） raising especially in frontal Cobe, parietal Cobe and temporal Cobe. The raised - power area was the pathological part involved in the poisoning, α wave can decline diffuse or locally. The positive rate of EEG is 63.6% and that of BEAM is 87.8%. After the treatment by HBO, the background wave generally is quicker like slow α wave, the positive rate is 27.2%. The power of BEAM fails down diffusely or locally and the positive rate is 30.2%. Coclusion It indicates that after the HBO treatment, the encephalon and oxygen - poor condition is improved and the cure rate is increased.
