脑电图监测对重型颅脑损伤后癫痫的诊断价值

Diagnostic value of electroencephalographic monitoring for seizures of severe brain injuries

目的 探讨重型颅脑损伤后早期癫痫的发生率及预防治疗。方法 对 6 7例重型颅脑损伤病人入ICU后立即行连续脑电图监测至伤后 7天。结果 16例经脑电图确诊为外伤性早期癫痫 ,诊断率为2 3.88%。临床观察到 6例有癫痫发作 ,其中 2例脑电图先出现癫痫波形 ,而后出现临床癫痫发作 ,临床诊断率为 9.0 0 %。结论 对重型颅脑损伤病人行连续脑电图监测可大大提高早期癫痫的诊断率。脑电图显示有癫痫波型者 ,应预防应用抗癫痫药 ,以防临床癫痫发作。

Objective To evaluate the incidence and prevention of early seizures caused by severe brain injuries.Methods Sixty-seven patients with severe brain injuries were undergone EEG monitoring which began at the admission to the ICU and lasted for 7 days postinjury.Results Sixteen patients with early seizures were diagnosed on the base of EEG studies alone.EEG diagnosed rate was 23.88%。There were seizures activities clinically in 6 cases and among them,first seizure wave on EEG and then seizure activity clinically in 2 cases.Clinical diagnosed rate was 9.00%.Conclusion Patients with severe brain injury should be monitored by continous EEG so that diagnosis rate of their early seizures can be elevated.As soon as there are seizures waves on EEG in the patient,anti-seizure drug should be used to prevent seizure activity clinically.
