Influencing factors of puncture site bleeding after trans-radial coronary intervention / 现代临床护理

ABSTRACT

Objective To investigate influencing factors of puncture site bleeding after trans-radial coronary intervention (TRI)in order to provide guidance for prevention of post-operative bleeding complications.Methods A total of 198 patients with TRI hospitalized at the department of interventional cardiology of our hospital from August,2011 to December,2011 were recruited in the study.In the prospective study,they were divided into two groupsbleeding group(n=62)and non-bleeding group(n=136).The general status,medication,position of radial compressor,time of immobilization of the wrist joint,duration of loosing tourniquet between the first time and second time and number of laps,time for depression,duration for total release of compression device and laboratory testing were recorded as data.Cox regression analysis was done to explore factors influencing bleeding.Results The factors for puncture site bleeding after trans-radial coronary intervention included pre-operative medications,location of compression device at the midline of operated forearm,distance between the compression device midpoint and the second wrist crease,and time for total release of compression device,with their RR=2.001,3.521,1.470 and 0.999,respectively.Conclusion Factors contributing to increased risk of local bleeding at puncture site following TRI included pre-operative medications,location of compression device at the midline of operated forearm,distance between the compression device midpoint and the second wrist crease;whereas the time for total release of compression device may be a protective factor.
