针刺对高血压病患者血流动力学的影响

The Effect of Acupuncture on Hemodynamic Indeices in Patients with Essential Hypertension

本文观察了49例Ⅱ期高血压病患者针刺风池、太冲等穴前后的血流动力学变化。发现针刺后较针刺前即刻收缩压平均降低3.2kPa(P<0.001),舒张压平均降低2.0kPa(P<0.001),外周阻力平均降低0.03kPa·s/ml(P<0.001),而动脉顺应性、每博心输出量和每分心输出量无明显变化(P均>0.05)。结果表明针刺的降压作用主要是通过降低细、小动脉的外周阻力,而对大、中动脉的顺应性以及心输出量影响不大。

In this paper hemodynamic chanses were observed in 49 cases of two—stage essential hypertension before and after needling points Fengchi (GB20), Taichong (LR3), etc. It was found that systolic blood pressuire was mean 3.2 KPa lower (p<0.001), diastolic blood pressure was mean 2.0 KPa lower (p<0.001) and peripheral resistance was mean 0.03 KPa·s/ml lower after acupuncture than immediately before acupuncture, while arterial compliance, stroke volume and cardiac output didn't change obviously (p>0.05 in all). The results shows that the hypotensive effect of acupuncture is obtained mainly through lowering the peripheral resistance of small arteries and not by influencing markedly the compliance of large and middle arteries and cardiac output.
