摘要
目的观察经皮电刺激双侧耳后乳突对缺血性卒中患者经颅多普勒超声(TCD)和脑干听觉诱发电位(BAEP)的影响。方法将40例缺血性脑卒中患者分为观察组和对照组(每组各20例)。两组均给予常规药物治疗,而观察组给予电刺激双耳后乳突部治疗。治疗前及治疗2周结束时均应用TCD和BAEP分别监测大脑前、中、后动脉(ACA、MCA、PCA)及椎动脉(VA)、基底动脉(BA)的血流速度和Ⅰ波、Ⅲ波、Ⅴ波潜伏期、Ⅰ～Ⅲ间期和Ⅲ～Ⅴ间期波峰间潜伏期的变化。结果与治疗前相比,治疗后两组TCD各项血流峰速度指标均有改善(P<0.05),而观察组显著优于对照组(P<0.001);观察组BAEP各指标也优于对照组(P<0.05)。结论电刺激双耳后乳突对缺血性脑卒中患者的血流速度及脑干神经传导功能改善有加强作用。
Objective To observe the effects of electric stimulation on mastoidea in the patients with ischemic stroke by transcranial Doppler sonography （TCD） and brainstem auditory evoked potentials （BAEP）.Methods 40 patients with ischemic stroke were equally divided into two groups,i.e.,observation group （20 cases） and control group（20 cases）.The two groups received routine treatment,while the observation group added electrical stimulation on mastoidea.The blood flow vecolity of anterior cerebral artery （ACA）,middle cerebral artery （MCA）,posterior cerebral artery （PCA）,vetebral artery （VA） and basilar artery （BA）,and the peak latency（PL） of wavesⅠ,Ⅲ and Ⅴ,and inter-peak latency（IPL） of Ⅰ-Ⅲ and III-V were examined by TCD and BAEP before and 2 weeks after treatment.Results The blood flow velocity in the observation group accelerated after treatment compared to pre-treatment（P〈0.05）.Compared with the control group,the blood flow velocity in the observation group accelerated more markedly（P〈0.001）.The nerve conduction in both groups improved after treatment.After treatment,PL of waves I,Ⅲ and V,and IPL of I-Ⅲ,III-V and III-V/I-Ⅲ in the observation group improved more significantly than the control group（P〈0.05）.Conclusion Electric stimulation on mastoidea can enhance the blood flow velocity of brain and the function of brainstem nerve conduction in patients with ischemic stroke.
