目的　观察脑通 (麦角溴烟酯 )治疗 2 8例椎基底动脉短暂缺血性眩晕的疗效。方法　采用高刺激率短声刺激ABR测试 ,比较治疗前后各波潜伏期及波间期。结果　治疗后高刺激率ABR异常出现率明显减少 ,各波潜伏期及波间期明显缩短。结论　脑通是治疗椎基底动脉短暂缺血性眩晕的有效药物 ,高刺激率ABR可客观评估其疗效 Objective To observe the curative effect of Nomoto (nicergoline) on 28 cases of vertebrobasilar transient ischemic vertigo. Methods The ABR test was performed with high stimulation rate and short-sonic stimulation. The latency and wave interval of each wave before and after treatment were compared. Results After treatment, the abnormal rate of ABR with high stimulus decreased significantly, and the latency and wave interval of each wave were significantly shortened. Conclusion Nao Tong is an effective drug for the treatment of transient ischemic vertigo of vertebrobasilar artery. The high stimulation rate ABR can objectively evaluate the curative effect
