临床脑死亡病人动态脑电图和脑波功率值监测分析

MONITORING ANALYSIS ON AEEG AND BRAIN WAVE POWER OF PATIENTS WITH CLINICAL BRAIN DEATH

目的:探讨动态脑电图(AEEG)和脑地形图(BEAM)对脑死亡的诊断价值。方法:对12例符合脑死亡临床标准的患者进行AEEG监测和BEAM分析。结果:Ⅰ级1例,Ⅱ级1例,Ⅲ级1例,Ⅳ级3例,Ⅴ级6例;AEEG脑电图由Ⅰ级向Ⅴ级演变;BEAM各脑波功率值与时降低。结论:临床脑死亡与AEEG表现趋同步,AEEG和BEAM对脑死亡诊断及预后评估有价值。

Objective:To study the value of AEEG and BEAM in diagnosis the brain death.Method:AEEG and BEAM of 12 patients according with the clinical standard of brain death were analyzed.Result:Grade Ⅰ was 1 case,Grade Ⅱ was 1 case,Grade Ⅲ was 1 case,Grade Ⅳ was 3 cases,Grade Ⅴ 6 was cases.AEEG develops from Grade Ⅰ to Grade Ⅴ.The power of each brain wave of BEAM lowers with time.Conclusion:The clinical brain death tends to appear gradually with AEEG.The AEEG and BEAM have certain value in diagnosis and prognostic assessment of brain death.
