瞬目反射及听觉诱发电位对脑干梗死的诊断价值

Blink Reflex and Brainstem Auditory Evoked Potential in the Diagnosis of Brainstem Infarction

目的:探讨瞬目反射(BR)和脑干听觉诱发电位(BAEP)检查对于脑干梗死患者脑干功能受损的诊断价值。方法:选择40例经头颅MRI检查证实的脑干梗死患者(梗死组),分别行BR和BAEP检查,计算BR各成分平均潜伏期,观察BAEP波形及各波潜伏期、峰间期,并与40例健康者作对照。结果:梗死组中BR检出脑干异常33例(82.5%),BAEP检出脑干异常32例(80%),两者联合检测脑干异常37例(92.5%)。结论:BR与BAEP均能敏感地反映脑干的病变,两者从不同的解剖路径反映了脑干病变的病理生理基础,有助于定位诊断。

Objective： To investigate blink reflex and brainstem auditory evoked potential in the diagnosis the function of brainstem in brainstem infarction. Methods： Forty patients proved brainstem infarction by MR were investigated compared with 40 healthy people. Patients were examined by BR and BAEP respectively. The mean incubation period in BR were calculated. The wave shape ,the peak latency and the inter-peak latency of each wave in BAEP were observed. Results： In 40 patients of brainstem infarction, 33 patients （82.5%） were detected to be injury in brainstem by BR, 32 patients （80%） were detected to be injury in brainstem by BAEP, 37 patients （92.5%）were detected to be injury in brainstem by connected detection BR and BAEP. Conclusion： Both BR and BAEP can reflect the affection in brainstem sensitively. Both things reflect the foundation of pathology and physiology from different anatomy pathways. They can provide the diagnosis of brainstem an addition and conduce to level diagnosis.
