目的 :了解慢性肾功能衰竭患者脑干听觉诱发电位 (BAEP)及瞬目反射 (BR )的变化。方法 :应用丹迪公司Keypoit型神经肌电描记仪对 3 2例慢肾衰患者进行脑干听觉诱发电位及瞬目反射检测 ,并与 3 5例同龄健康人的检测结果作比较。结果 :慢肾衰患者组BAEP显示Ⅰ、Ⅲ、Ⅴ波潜伏期和Ⅰ～Ⅲ、Ⅰ～Ⅴ波峰间潜伏期明显延长 ,Ⅲ～Ⅴ波峰间潜伏期基本正常。BR显示R1 波、R2 波和R2 ’波均明显延长。结论 :慢肾衰病人存在多发周围性颅神经损害 ,脑干中枢受损相对较轻
Objective: To investigate the changes of brainstem auditory evoked potential (BAEP) and blink reflex (BR) in patients with chronic renal failure. Methods: The brainstem auditory evoked potentials and blink reflexes of 32 patients with chronic renal failure were detected by using the Keypoit electromyogram of Dandy Company, and compared with the test results of 35 healthy people at the same age. Results: The BAEP of patients with chronic renal failure showed that the latency of Ⅰ, Ⅲ and Ⅴ waves and the latency of Ⅰ ~ Ⅲ, Ⅰ ~ Ⅴ peaks were prolonged obviously, while the latency of Ⅲ ~ Ⅴ peaks was basically normal. BR shows that R1 wave, R2 wave and R2 ’wave are obviously prolonged. Conclusion: There are multiple peripheral cranial nerve damage in patients with chronic renal failure, and the damage of the central trunk of brain stem is relatively mild
