RESUMO
Objective To observe the different methods of hemostasis and comfort of the TR -Band com-pression hemostasis device after coronary intervention and to find the best strategy for TR -Band to stop the bleeding. Methods 150 patients with coronary artery disease were randomly divided into three groups according to the digital table method.The initial time of TR -Band compression hemostasis of group A was 3h,(once per hour,2mL per time,total compression time was 10h),while that of group B was 2h(once in every two hours,3mL per time,total com-pression time was 8h),and that of group C was 1h(once per hour,2mL per time,total compression time was 6 h). Thumb oxygen saturation,complications and comfort level in the three groups of patients were observed and compared. Results The differences between the three groups of oppression hemostasis before and after 2 h thumb oxygen saturation were normal,the three groups had no statistical significance (P >0.05).lesions,hematoma,bruising and radial artery occlusion occurred rate of group A were respectively 4,3,5,2 cases,those of group B were 3,4,6, 1 cases,and those of group C were 2,5,6,0 cases.Lesions,hematoma,bruising,radial artery occlusion of local com-plication incidence of the three groups showed no statistical significance (P >0.05).The comfort level (numbness, swelling,pain)of the three groups had statistically significant differences (Fnumbness =8.215,Fswel ing =7.657,Fpain =7.985,all P <0.01).Conclusion TR -Band compression hemostasis device can achieve effective hemostasis in the treatment of coronary artery intervention.And the reasonable adjustment of different bleeding time,compression time and the amount of bleeding can affect the comfort of patients.
