| 摘 要： | 目的 探讨闭合性颅脑外伤患者视觉P300地形图的变化。方法 使用Medicide- 03E诱发电位仪对103例闭合性颅脑外伤患者(脑外伤组)进行视觉剌激P300地形图检测,并与66例包括正常人、神经症患者及其他非脑外伤疾病而P300地形图正常者进行对照。结果 脑外伤组患者P300波潜伏期较对照组明显延长(P<0 .001),波幅降低(P<0 .01);视觉P300地形图显示两侧不对称性和扩散性。结论 闭合性颅脑外伤患者视觉P300地形图存在偏侧性和扩散性。

Preliminary study of P300 topography mapping in patients with closed craniocerebral trauma |
| |
| Abstract: | Objective To investigate changes of the visual P300 topography mapping in patients with closed craniocerebral trauma.Methods The visual P300 topography mapping was recorded from 103 patients with closed craniocerebral trauma and 66 normal subjects with a medicide-03E brain evoked potential instrument. Results The P300 latency in patient group was significantly prolonged as compared with the control group ( P<0.001) and the amplitude was decreased ( P<0.01).The visual P300 topography mapping showed asymmetrical distribution and diffusibility in patient group.Conclusion P300 topography mapping in the patients with closed craniocerebral trauma showed asymmetrical distribution and diffusibility. |
