The research of time of bandage removal after coronary angiography through the radial artery

AIM To study the time of bandage removal after coronary angiography through the radial artery.

METHODS 300 patients were selected with coronary heart disease who underwent coronary angiography but without stent implantation were divided into three groups according to postoperative pressurized bandaging time: a 4 h group (100 patients), a 6 h group (100 patients), a 8 h group (100 patients). The present investigation observed incidence of complications, including puncture point bleeding, forearm hematoma, limb necrosis, skin blister formation, discomfort of patients, routine blood work, prothrombin time (PT) and activated partial thromboplastin time (APTT) changes.

RESULTS There were no significant differences in routine blood, prothrombin times, and activated partial thromboplastin times between the three groups before operation. There were no significant differences in incidence of bleeding at 4 h, 6 h and 8 h punctures after operation. There were no significant differences in puncture point bleeding, forearm hematoma, limb necrosis or local skin blister formation between the three groups. The discomfort in group 4 h was significantly lower than that in the 6 h and 8 h groups.

CONCLUSION Based on the results of this study, bandage removal at 4 h after coronary angiography through the radial artery was safe with no obvious bleeding in the puncture point.
