[Effects of needle retaining at Zusanli (ST 36) on hemodynamic change of anterior tibial artery].

OBJECTIVE: To observe the effects of needle retaining on hemodynamic change and investigate the significance of retaining needle. METHODS: 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. RESULTS: 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). CONCLUSION: Needle retaining can not change regional hemodynamic.
