针刺风池对高血压患者椎-基底动脉血流速度的影响

Effect of Acupuncture at Fengchi (GB20) on Blood Flow Velocity of Vertebrobasilar Artery in Hypertension Patients

目的观察针刺风池对高血压患者椎-基底动脉血流速度的影响。方法将经TCD检查提示椎-基底动脉血流速度减慢的原发性高血压患者60例随机分为对照组、治疗组,每组30例。对照组给予苯磺酸氨氯地平5 mg口服,每日1次;治疗组在口服苯磺酸氨氯地平的基础上针刺风池治疗,每日1次。以治疗前后患者血压及椎-基底动脉血流速度的改变评价其疗效。结果治疗组在降压与改善椎-基底动脉血流速度方面均优于对照组,两组比较差异有统计学意义(P<0.05)。结论针刺风池有降低血压及明显增快椎-基底动脉血流速度的作用,且与苯磺酸氨氯地平联合可有效降低患者血压,改善脑血流量。

Objective To observe the effect of acupuncture at Fengchi （GB20） on blood flow velocity of vertebrobasilar artery in patients with hypertension. Method Sixty primary hypertension patients diagnosed by transeranial Doppler （TCD） with decreased blood flow velocity of vertebrobasilar artery were randomized into a control group and a treatment group, 30 each. The control group was given Amlodipine at 5 mg per dose, once every day; the treatment group was given acupuncture at Fengchi in addition to Amlodipine, once every day. Therapeutic effect was determined by evaluating the changes of blood pressure and blood flow velocity of vertebrobasilar artery. Result The treatment group was better than the control group in anti-hypertension and improving blood flow of vertebrobasilar artery, and the differences were statistically significant （P〈0.05）. Conclusion Acupuncture at Fengchi is effective in lowering blood pressure and raising blood flow velocity of vertebrobasilar artery, and its combining use with Amlodipine can effectively lower patient＇s blood pressure and improve cerebral blood flow.
