ObjectiveTo explore the effect of finger movements on preventing radial artery occlusion (RAO), the changes of the postoperative hemodynamic parameters of the radial artery in patients were observed dynamically, and the effects of the finger dance exercise on the early and late RAO occurrence were analyzed.

MethodsA total of 171 patients undergoing elective coronary angiography and interventional therapy were randomly divided into control group (89 patients) and observation group (82 patients).The observation group carried out finger movements for 3 h after surgery, and none was performed in the control group.The thickness, diameter and peak flow velocity of the radial artery were measured before puncture, 3 days and 1 month after surgery.The changes of the above indicators were dynamically observed, and the early and late RAO occurrence were analyzed.

ResultsThe age, gender, smoking, combined disease and other clinical characteristics of patients in the two groups were not significantly different (P>0.05).The radial artery diameter and intimal thickness in the observation group had no statistical significance compared with the control group in the same period before surgery, 3 days and 1 month after surgery (P>0.05).The peak flow velocity of radial artery in the observation group had no statistical significance compared with the control group before surgery (P>0.05), but the peak flow velocity of radial artery in the observation group was higher than that in the control group 3 days and 1 month after surgery (P < 0.05).On the third day after surgery, the early RAO rate in the observation group was 5.7% (4/70), lower than the 16.3% (13/80) in the control group (P < 0.05).At 1 month after surgery, no RAO occurred in the observation group, and the occlusion rate was 0% (0/68), which was lower than 14.9% (11/74) in the control group (P < 0.01).The incidence of adverse reactions such as forearm swelling and puncture point blood infiltration was not significantly different between the two groups (P>0.05).

ConclusionsFinger movements helps to improve the early radial artery blood flow velocity, can significantly reduce the occurrence of early and late RAO after coronary angiography, and does not significantly affect the incidence of adverse reactions.Postoperative finger dance exercise is a simple, safe and effective prevention strategy for RAO.
