目的研究急性脑血管病患者脑干听觉诱发电位（ＢＡＥＰ）变化。方法２４３例发病７天内的急性脑血管病患者和１２２例正常人进行ＢＡＥＰ检查。结果急性脑血管病患者ＢＡＥＰ异常率为８５．６％，明显高于正常对照组２５．４％，Ｐ＜０．０１。病情严重患者ＢＡＥＰ异常率为１００％，而轻、中型患者分别为７９．２％和８３．７％，与严重患者比较，Ｐ＜０．０１。ＢＡＥＰ异常主要表现为主波潜伏期和波间期延长，主波消失或分化不良。结论脑干听觉诱发电位可作为判断急性脑血管病的预后和观察病情变化的一项客观指标。
Objective To study the changes of brainstem auditory evoked potential (BAEP) in patients with acute cerebrovascular disease. Methods 243 patients with acute cerebrovascular disease within 7 days of onset and 122 normal subjects underwent BAEP examination. Results The abnormal rate of BAEP in patients with acute cerebrovascular disease was 85.6%, significantly higher than that in normal control group (25.4%, P <0.01). The abnormal BAEP rate was 100% in patients with severe disease, compared with 79.2% and 83.7% in light and medium patients, respectively, P <0.01 compared with severe patients. BAEP abnormalities mainly manifested as the main wave latency and wave interval prolongation, the main wave disappeared or poorly differentiated. Conclusion Brainstem auditory evoked potentials can be used as an objective index to judge the prognosis of acute cerebrovascular disease and observe the changes of the disease.
