针刺百会穴对急性缺血性卒中患者大脑中动脉血流即时效应的影响

目的观察针刺百会穴对急性缺血性卒中患者大脑中动脉血流影响的即时效应。方法设针刺百会治疗组（百会组）与对照组进行对照观察，将23例急性缺血性卒中患者随机分成百会组12例和对照组11例。两组于针刺前后分别进行经颅多普勒超声（TCD）检查，观察大脑中动脉收缩期峰速（Vs）、舒张期峰速（Vd）、平均流速（Vm）、搏动指数（PI）及阻力指数（RI）的变化。结果百会组与对照组比较，针刺前后大脑中动脉Vs、Vd、Vm差异有统计学意义（P〈0．05），PI和RI差异无统计学意义（P〉0．05）；百会组TCD探测深度52mm和56mm的Vs和Vm针刺前后的变化均优于对照组，差异有统计学意义（P〈0．05）。结论针刺法能使大脑中动脉血流量增加，且针刺百会穴更有优势。

Influence of needling Baihui point on immediate effect of middle cerebral artery blood flow in patients with acute ischemic stroke

Objective To observe the immediate effect of needling Baihui point on the middle cerebral artery（MCA） blood flow in patients with acute ischemic stroke. Methods The research objects were observed by establishing treatment group of needling Baihui point（Baihui group） and control group. 23 patients with acute ischemic stroke were randomly divided into Bai- hui group （n=12） and control group （n=l 1 ）. Both groups were checked by transcranial doppler （TCD） before and after acupunc- ture. The changes of peak systolic velocity （Vs）, diastolic peak velocity （Vd）, mean velocity （Vm）, pulsatility index （PI） and drag index（DI） of MCA in the two groups were observed. Results The difference of Vs,Vd and Vm of the MCA before and after acupunc- ture between the two groups had statistical significance （P〈0.05）, but the difference of PI and RI had no statistical significance （P〉 0.05）. When the investigation depth was 52 mm and 56 mm,the changes of Vs and Vm before and after acupuncture in Baihui group were both superior to the control group with statistically significant difference （P〈0.05）. Conclusion Acupuncture can rise the flow velocity of MCA, and the needling Baihui point has much more advantage.
