title: [Effects of needle retaining at Zusanli (ST 36) on hemodynamic change of anterior tibial artery].
abstract: 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).
  
  
  CONCLUSIONS
  Needle retaining can not change regional hemodynamic.
