摘　　要：目的:观察脑电图的95%频谱边界频率(spectral edge frequency,SEF 95%)与意识障碍程度的相关性。方法:对2007年7月至2008年4月我院神经内科ICU收治的意识障碍患者,分为嗜睡、昏睡、浅昏迷、中昏迷、深昏迷5个意识水平,按Glasgow昏迷量表(GCS)进行评分,同时行SEF 95%、频谱总功率(total power,TP)检查,共有42组数据纳入分析,分别分析意识水平与SEF 95%、GCS评分、TP,GCS评分与SEF 95%、TP的相关性。结果:经Spearman相关分析,SEF 95%与意识水平(r=-0.663,P=0.001呈负相关,SEF 95%与GCS评分(r=0.861,P=0.000)呈正相关,TP与GCS评分(r=0.421,P<0.01)呈正相关。GCS评分与SEF 95%行直线回归分析,直线回归方程为GCS=2.616+0.425 SEF 95%(t=9.02,P=0.000)。结论:SEF 95%可作为评判患者意识障碍程度的指标。Objective:To observe the correlation between spectral edge frequency(SEF 95%)of electroencephalogran(EEG)and degree of conscious disturbance. Methods: Forty-two patients with unconscious who were admitted in NICU from July 2007 until February 2008 were grouped with somnolence,stupor,mild coma,moderae coma and profound coma.Glasgow coma scores (GCSs) of them were counted.At the same time,SEF 95% and total power(TP)were examined.The data sets of the patients were inclunded for analysis to explore the correlat...
