摘要
目的:探讨重型脑损伤患者急性期定量脑电图的变化与预后的关系。方法:选用数字化脑电监测系统,对120例重庆医科大学附属第一医院神经外科2002-01/2003-04收治急性重型脑伤损患者(格拉斯哥昏迷量表评分≤8分)于伤后行床旁脑电图监测,平均监测时间为5d,比较急性重型脑损伤患者脑电功率值变化与患者预后的关系。结果:①重型脑损伤患者初次脑电图分级Ⅱ,Ⅲ,Ⅳ,Ⅴ级生存率分别为69%,70%,8%,0%;病死率分别为31%,30%,92%,100%。②死亡患者急性期脑电图总的绝对功率下降明显,伤后24h明显低于生存组;相对功率值中,慢波频段的显著下降及β频段相对功率值的异常增高提示预后极差。结论:重型脑伤急性期定量脑电图变化对判断脑功能及预后有重要的价值。
AIM: To study the relation between the changes of quantitative electroencephalogram(EEG) and the prognosis in patients with acute severe brain injury. METHODS:Between January 2002 and April 2003, 120 cases of acute severe brain injury (Glasgow Coma Scale GCS≤8) hospitalized in the Department of Neurosurgery, First Affiliated Hospital, Chongqing Universtiy of Medical Sciences were monitored with digital EEG for an average of 5 days post injury. The average duration for monitoring was 5 days. The results of EEG power spectrum and patient outcomes were compared. RESULTS: ①Initial EEG grade of patients with acute severe head injury showed that survival rate of Ⅱ, Ⅲ, Ⅳ, Ⅴwas respectively 69%, 70%, 8%, 0%and death rate was respectively 31%, 30%, 92%, 100%. ②The total absolute power of the death patients at acute period decreased significantly, significantly lower than that of the survival patients 24 hours after injury. The significant decrease of relative power of slow band and abnormal increase of β band showed worse prognosis. CONCLUSION: Quantitative EEG is a important parameter to evaluate the brain function and prognosis of patients with acute severe head injury.
