摘要
目的探讨针灸"得气"的生理基础。方法未经历过针灸治疗的健康成年志愿者28名,在不同的时间针刺右侧足三里(ST36)和足三里外侧1.5 cm(A点),足三里分浅刺和深刺,A点为深刺。利用彩色多普勒超声观察胫前动脉在针刺前、进针结束时和得气3 min时收缩期峰值(Vmax)、平均血流速度(Vm)和血管内径(Dist)。结果深刺足三里得气3 min后与针刺前相关指标有显著性差异(P<0.05);浅刺足三里运针3 min后与针刺前相关指标均无显著性差异(P>0.05);足三里和A点深刺在运针3min后Vmax和Vm具有显著性差异(P<0.05)。结论动脉血流的动力学变化可能与针灸得气有关。
Objective To study physiological foundation of acupuncture Deqi. Methods 28 healthy volunteers who never experi enced acupuncture were recruited. The right Zusanli （ST36） and a site 1.5 cm beside Zusanli （ST36） （nominated as A） were acu punctured at different time. Shallow and deep acupuncturing was inserted at Zusanli （ST36）. Only deep acupuncturing was inserted at A. Hemodynamic parameters of the anterior tibial artery including the peak value in the systolic phase （Vmax）, the average blood flow velocity （Vm）, and the inner diameter of vessels （Dist） were observed with colored Doppler ultrasound before, at the end of acupuncture, and 3 min after Deqi response. Results There was significant difference in those parameters between before acupuncture and 3 min after deqi response when deep acupuncturing at Zusanli （ST36） （P〈0.05）, but was not significant difference when shallow acupuncturing （P〉0.05）. There was significant difference in △Vmax and AVm between acupuncture at Zusanli （ST36） and A points （P〈0.05）. Conclusion Arterial haemodynamics variation seems to be associated with acupuncture Deqi.
