Modified inflatable compression method applied on patients underwent transradial CAG / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the effect of modified inflatable compression method on patients underwent transradial CAG. Methods: Totally 100 patients underwent elective transradial CAG were randomly divided into modified group and control group (each n=50). Patients in modified group were treated with modified inflatable compression method after transradial CAG, and those in control group with conventional compression method. Swollen overflow and numerical pain rating scale (NPRS) were compared between the two groups at the end of compressing radial artery for 2 h and 4 h. When the compressor was removed after 6 h compression, the hemorrhage cases on radial artery puncture point were counted, and the cases of radial artery occlusion after 24 h were calculated and compared between the 2 groups. Results: Swollen overflow and NPRS at the end of 2 h and 4 h of compression were significantly lower in modified group than those in control group (all P<0.01). Hemorrhage after 6 h compression and removing the compressor was observed in 3 patients in modified group and 2 patients in control group (P=1.00). Radial artery occlusion was detected in 1 case in modified group and 2 cases in control group 24 h later (P=1.00). Conclusion: The modified inflatable compression method can reduce the postoperative limb swelling and pain of patients underwent transradial CAG without increase of hemorrhage at the puncture point nor vascular occlusion.
