目的 :探讨急性脑梗死溶栓治疗脑电图改变。方法 :采用 SW- JH2 0 0 0 AR智能化脑电监护仪 ,对 10例急性脑梗死(发病 <6 h)患者溶栓治疗前中后同步进行脑电图动态监测 ,按冯应琨《临床脑电图学》的诊断标准进行分析。结果 :脑电图 (EEG)反应溶栓过程中随溶栓剂用量增加有经时变化之特征 ,静注 5 0万 u尿激酶 (天普洛欣 ) ,慢波明显增多 ,频率变慢 ,定位更明确 ,追加静点 10 0万 u后 ,慢波减少频率增快。 8例患者随 EEG改变 ,肌力恢复显著 ,2例肌力恢复差者复查头颅 CT为大面积脑梗死 ,EEG表现慢波减少 ,1例呈各导联 α波增强 ,1例 θ波明显增多。结论 :(1)急性脑梗死超早期脑电图的异常程度对选择溶栓治疗有指导意义 ;(2 )超早期溶栓治疗同步行脑电图动态监测对患者近期病情演变及预后可作出初步判断。
Objective: To investigate the changes of EEG after thrombolytic therapy in acute cerebral infarction. Methods: SW-JH2 0 0 0 AR intelligent EEG monitor was used to monitor EEG dynamic changes in 10 patients with acute cerebral infarction (onset <6 h) before and after thrombolysis. According to Feng Ying-kun’s “Clinical EEG Figure ”diagnostic criteria for analysis. Results: With the increase of thrombolytic agents, the amount of thrombolytic agents increased with time and the amount of thrombolytic agents increased with the dose of thrombolytic agents (EEG) Positioning more specific, additional static 10 million u, slow wave to reduce the frequency faster. 8 cases of patients with EEG change, significant muscle strength recovery, 2 cases of poor muscle recovery recanalization of cranial CT for large-area cerebral infarction, EEG showed slow wave reduction, 1 case of each lead α-wave enhancement, 1 case of θ-wave increased significantly . Conclusion: (1) The ultra-early EEG abnormality of acute cerebral infarction is instructive for the choice of thrombolytic therapy; (2) The ultra-early thrombolytic therapy with synchronous dynamic monitoring of EEG can make a preliminary assessment of the patient’s recent disease progression and prognosis judgment.
