160例颅脑外伤患者脑电图与CT结果的比较

THE CONTRAST BETWEEN EEG AND CT ON 160 PATIENTS WITH CRANIAL TRAUMA

目的:探讨脑电图检查在颅脑外伤中的应用,并与CT结果作比较。方法:对160例颅脑外伤患者进行EEG和CT检查。结果:(1)脑电图异常率为69.4%,主要表现为不同程度的慢波增多,CT异常率为33.7%;(2)颅脑外伤EEG严重程度和外伤程度有关,外伤程度越高其EEG异常率越高;(3)轻和中型颅脑外伤EEG较CT异常率高,提示大多为脑功能变化而非结构性改变,而重型颅脑外伤两者结果无明显差异。结论:(1)EEG和CT检查在颅脑外伤中只能相互补充,不能相互取代;(2)EEG检查对颅脑外伤患者的病情判断、预后评估及临床治疗有确定的价值。

Objectives ：To explore the application of EEG in patients with cranial trauma and comparison with CT. Methods：EEG and CT were examined in 160 cases with cranial trauma. Results： （ 1 ） EEG abnormal rate is 69.4% , In most cases slow waves increased, （ 2 ） EEG changes are related closely with degree of cranial trauma. The more serious the trauma is the higher EEG abnormal rate. （3） In light and middle cases of cranial trauma EEG abnormal rate is higher than CT, and most are changes of function brain but isn＇t structural changes. However, in serious cases with cranial trauma EEG and CT abnormal rates are not very different. Conclusions： EEG might be of certain value in the evaluation of the degress and prognosis of cranial trauma and treatment.
