Effects of needle retaining at Zusanli (ST 36) on hemodynamic change of anterior tibial artery / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effects of needle retaining on hemodynamic change and investigate the significance of retaining needle.</p><p><b>METHODS</b>Manual acupuncture was performed at the left Zusanli (ST 36) of 26 healthy adult volunteers who have not receiued acupuncture. 26 cases were randomly divided into a needle retaining group and a quick needling group, 13 cases in each group. Hemodynamic parameters of the anterior tibial artery were observed with color Doppler ultrasound before needling and 0, 1, 2, 3, 4 and 5 minutes after needle manipulation. Hemodynamic parameters were also compared between the two groups 0, 1, 2, 3, 4 and 5 minutes after needle manipulation.</p><p><b>RESULTS</b>There were no significant difference in V(max) and Vm between 0, 1, 2, 3, 4 and 5 minutes after needling manipulation (all P > 0.05).</p><p><b>CONCLUSION</b>Needle retaining can not change regional hemodynamic.</p>
