To investigate the efficiency of chitosan hemostatic dressing combined radial artery hemostasis device in patients after transradial coronary intervention.

Six hundred consecutive patients after transradial coronary intervention were selected and randomly divided into the experimental group and the control group according to the hospital number, there were 300 cases in each group. Single pneumatic tourniquet was used in the control group, while the chitosan hemostatic dressing combined with pneumatic tourniquet was used in the experimental group. Hemostasis consumption time, incidence of bleeding, ecchymosis and radial arterial occlusion were compared between two groups.

There was no significant difference in the incidence of skin ecchymosis between two groups,P>0.05. The hemostasis consumption time and the incidence of bleeding,early radial arterial occlusion and chronic radial arterial occlusion were (127.6±33.0)min, 7.0%(21/300), 5.7%(17/300), 4.0%(12/300)in the experimental group and (181.6±32.2)min, 20.0%(60/300), 11.7%(35/300), 9.0%(27/300)in the control group,t or χ² values were 20.258, 21.708, 6.822, 6.170 respectively, and there were significant differences,P<0.01 or <0.05.

In patients after transradial coronary intervention, the application of chitosan hemostatic dressing combined with pneumatic tourniquet is safer and more effective than using pneumatic tourniquet alone.
