Abstract：Objective The purpose of this study was to explore the risk factors of diminished radial pulse and analyze the effectiveness of preventive methods for diminished radial pulse following trans-radial intervention(TRI).Methods A total of 2136 patients who underwent TRI were divided into diminished pulse group and normal group by palpation near the original entry site.The risk factors of diminished radial pulse were analyzed by multivariate logistic regression.For patients with significantly diminished radial pulse,continuous freehand compression of the ipsilateral ulnar artery(UA)was used to block blood flow to restore radial pulse.Results In 149 patients(6.98%)diminished radial pulse was examined by palpation.The ratios of female and percutaneous coronary intervention(PCI)history in diminished pulse group were higher than in normal group(P<0.05).Duration of post-procedure compression and duration of sheath reservation in diminished pulse group were longer than in normal group(P<0.05).Multivariate logistic regression model analysis showed that duration of post-procedure compression and duration of sheath reservation were positively correlated with diminished radial pulse.Through the compression of the ipsilateral UA,radial pulse was restored in 148 patients.The effective rate was 99.33%in the study.Conclusion Duration of post-procedure compression and duration of sheath reservation were risk factors of diminished radial pulse.Continuous freehand compressing ipsilateral UA to block its blood stream can effectively restore postoperative radial pulse.
