摘要
目的观察脑震荡伤者脑干听觉诱发电位(brainstem auditory evoked potential,BAEP)的变化。方法对19例脑震荡伤者进行BAEP检测,并与文献报道的正常人的异常率进行比较。结果脑震荡伤者BAEP的异常率为89.5%,明显高于正常对照组(P<0.05)。其中脑干段电反应异常率达73.7%,提示脑震荡伤者存在脑干功能障碍。结论BAEP对脑震荡损伤的认定有一定的价值。
Objective To investigate changes of brainstem auditory evoked potential （BAEP） in patients with brain concussion. Methods Nineteen patients with brain concussion were studied with BAEP examination. The data was compared to the healthy persons reported in literatures. Results The abnormal rate of BAEP for patients with brain concussion was 89.5%. There was a statistically significant difference between the abnormal rate of patients and that of healthy persons（P〈0.05）. The abnormal rate of BAEP in the brainstem pathway for patients with brain concussion was 73.7%, indicating dysfunction of the brainstem in those patients. Conclusion BAEP might be helpful in forensic diagnosis of brain concussion.
