Objective To investigate the impact of selective ulnar artery continuous circulatory compression in reducing radial artery occlusion in elderly patients undergoing coronary intervention for coronary artery disease.
Methods A total of 450 elderly patients with coronary heart disease undergoing coronary intervention were selected as study objects, and were randomly divided into control group and experimental group, with 225 patients in each group. The control group received non-occlusive radial artery compression postoperatively, while the experimental group underwent selective ulnar arteria continuous circulatory compression using a customized pulse wave sphygmomanometer on the basis of the control group for a duration of 4 hours. Puncture site bleeding, pain, thumb skin temperature, nursing workload, delayed pressure measurement rate, radial artery blood flow velocity, and rates of radial artery occlusion and stenosis were compared between the two groups 24 hours postoperatively.
Results There were no significant differences in puncture site bleeding, pain, thumb skin temperature, nursing workload, and delayed pressure measurement rate between the two groups (P>0.05). However, the experimental group presented significantly faster radial artery blood flow velocity 0.5 hours before removing the blood pressure monitor, as well as lower rates of radial artery occlusion and stenosis 24 hours postoperatively compared to the control group (P < 0.05).
Conclusion The use of a blood pressure monitor for selective continuous circulatory compression for a duration of 4 hours can enhance radial artery blood supply and reduce rates of postoperative radial artery occlusion and stenosis in elderly coronary intervention patients under the premise of not increasing the risk of bleeding, pain, nurse workload and delayed pressure extraction.
