摘要
目的：研究高血压脑出血患者脑干听觉诱发电位（ＢＡＥＰ）与脑血流量（ＣＢＦ）的相关性。方法：检测８３例高血压脑出血患者和７５例正常人的ＢＡＥＰ及用１３３Ｘｅ吸入法测定ＣＢＦ。结果：脑出血患者ＢＡＥＰ和ＣＢＦ异常率分别为６９．９％和６３．９％，病情愈重则异常率愈高，脑出血量大者ＢＡＥＰ和ＣＢＦ异常率高于出血量少者，Ｐ＜０．０５～０．０１。脑出血患者ＢＡＥＰ主波潜伏期和波间期均比正常对照组明显延长，Ｐ＜０．０５～０．０１；ＢＡＥＰ异常患者ＣＢＦ明显低于ＢＡＥＰ正常患者，Ｐ＜０．０５～０．０１。结论：ＢＡＥＰ是评估脑出血患者脑干功能和脑血流量的良好手段。
Objective:To study the relationship between brainstem auditory evoked potentials (BAEP) and cerebral blood flow (CBF) in patients with hypertensive cerebral hemorrhage.Methods:BAEP and CBF ( 123 Xe inhalation method) were determined in 83 patients with hypertensive cerebral hemorrhage and 75 healthy volunteers (control group).Results:Abnormal rate of BAEP and CBF were 69 9% and 63 9% in patients with hypertensive cerebral hemorrhage.As the severity of illness increased,abnormal rates of BAEP and CBF became much higher.Also,abnormal rates were higher in serious hemorrhage than that in mild hemorrhage ( P <0 05～0 01).The peak latency (PL) and inter peak latency (IPL) in cerebral hemorrhage group were significantly longer than those in controls ( P <0 05～0 01).In addition,CBF in abnormal BAEP was much lower than that in normal BAEP( P <0 05～0 01).Conclusions:BAEP is a good method in evaluating the function and CBF of brain in patients with hypertensive cerebral hemorrhage.
