Aim To study the application effect of artificial compression and elastic bandages and bandages with dehydration, when the forearm tensition hematoma occurred after transradial coronary intervention （TRI）, to investigate the advantages and disadvantages of the three different methods in the hematoma elimination, and to provide the method of scientific treatment when the hematoma were found. Methods Using a hand pressure （A group） and bandages （B group） and bandage compress with dehydration （C group） to deal with forearm tensition hematoma in 215 patients, during 4 years in our department. The ANOVA was used in statistical analysis, and the effects with three different methods of processing were compared. Results In the 215 patients of forearm tensition hematoma, the comparison of group A and group B, the average time of the swelling subsiding, the time of finger blood supplying and function, the time of occurrence of the surrounding skin temperature increase, and forearm arm circumference were not improved （P>0.05）, the difference was not statistically significant the 70 patients in B group were given in compression by the tension bandage, the 76 patients in C group were given in compression by the tension bandage and dehydrated with mannitol or dexamethasone and so on by comparing C group with B group, the time of forearm subsiding was shortened obviously （P<0.05）, the differences has statistics significance the skin temperature had risen slightly （P>0.05）, the difference has no statistic significance the time was reduced obviously, which is improvement time of blood and function of the finger, and the arm circumference
