急性脑血管病患者脑干听觉诱发电位研究

Brainstem auditory evoked potentials in patients with acute cerebral vascular disease.

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。

Objectives To study the changes of brainstem auditory evoked potentials (BAEP) in patients with acute cerebral vascular disease(CVD). Methods The BAEP was performed on 243 patients with acute CVD in 7 days after the onset and 122 normal subjects. Results The abnormality rate of BAEP was 85.6% in CVD group ,significantly higher than that in the control group (25.4%)( P <0.01).The abnormality rate of BAEP in the serious patients was 100%,significantly higher than that in the mild and the moderate ones (79.2% and 83.7%) .The main abnormalities of BAEP were:prolongation of peak latency (PL) and inter peak latency (IPL), disappearance or undifferentiation of the main waves. Conclusions The BAEP can be used as an index in evaluation the outcome of the CVD and the patient′s condition.
