173例颅脑外伤脑电图变化并与CT结果的比较

CHANGE OF EEG ON 173 PATIENTS WITH CRANIAL TRAUMA AND COMPARISON WITH CT

目的:探讨脑电图检查在颅脑外伤中的应用,并与 CT 结果比较。方法:对173例颅脑外伤患者进行 EEG 和 CT 检查。结果:发现 EEG 异常率为46.8%,主要为不同程度慢波增多,部分病例还出现局灶性变化及痫样波。结论:1、颅脑外伤 EEG 变化与其严重程度密切相关,外伤严重程度愈高,其 EEG 异常率愈高,出现局灶及痫样波机率也愈多。2、轻及中型颅脑外伤 EEG 较 CT异常率高,提示大多系脑功能变化而非结构性改变;而重型颅脑外伤两者无明显差异。3、动态检查 EEG 有重要临床价值。

Objective:To explore the application of EEG in patients with cranial trauma and compari- son with CT.Method:EEG and CT were examined in 173 cases with cranial trauma.Results:EEG abnormali rate is 46.8%.In most cases,slow waves increased,and in some cases,local changes and epileptic waves ap- peared.Conclusions:1.EEG changes are related closely with degree of cranial trauma.The more serious the trarma is,the higher EEG abnormal rate is and the more local changes as well as epileptic waves appeared.2.In light and middle cases of crannal trarma,EEG abnormal rate is higher than CT,and most are changes of function brain but not structural changes.However,in serious cases with cranial trauma,EEG and CT abnormal rates are not very different.3.Monitor of EEG was important clinical valuable.
