低频电刺激辅助丁苯酞治疗后循环缺血性眩晕症

Low-frequency electrical stimulation assisted with butylphthalide in the treatment of posterior circulation ischemic vertigo

目的观察低频电刺激辅助丁苯酞对后循环缺血性眩晕患者眩晕症状及脑血流的影响。方法选取2021年2月至2022年12月收治的后循环缺血性眩晕患者74例,随机分为对照组与研究组,每组37例。对照组在常规治疗基础上加用丁苯酞,研究组在对照组基础上予以低频电刺激。比较两组眩晕症状评分、血液流变学指标及脑血流量。结果治疗后,研究组眩晕症状评分明显低于对照组,差异有统计学意义(P<0.05)。治疗后,研究组全血黏度、全血黏度高切、全血黏度低切均明显低于对照组;右侧椎动脉血流速度、左侧椎动脉血流速度、椎-基底动脉血流速度均明显高于对照组(P<0.05)。结论低频电刺激辅助丁苯酞治疗后循环缺血性眩晕患者能有效改善眩晕症状,降低血液黏度,提高脑血流量。

Objective To observe the effects of low-frequency electrical stimulation assisted with butylphthalide on dizziness symptoms and cerebral blood flow in patients with posterior circulation ischemic dizziness.Methods 74 patients with posterior circulation ischemic vertigo admitted to our hospital from February 2021 to December 2022 were randomly divided into the control group and study group using a random number table,with 37 cases in each group.The control group were received conventional drug therapy combined with butylphthalide,while the study group were received low-frequency electrical stimulation on the basis of the control group.The vertigo symptom score,hemorheology index and cerebral blood flow were compared between the two groups.Results After treatment,the score of dizziness symptoms in the study group was significantly lower than that in the control group,with a statistically significant difference(P<0.05).After treatment,the whole blood viscosity,high shear of whole blood viscosity,and low shear of whole blood viscosity in the study group were significantly lower than those in the control group;the right vertebral artery blood flow velocity,left vertebral artery blood flow velocity,and vertebral basilar artery blood flow velocity in the study group were significantly higher than those in the control group(P<0.05).Conclusion The use of low-frequency electrical stimulation assisted with butylphthalide in the treatment of patients with recurrent ischemic dizziness can effectively improve their dizziness symptoms,reduce blood viscosity,and increase cerebral blood flow.
