改良充气压迫法用于经桡动脉冠状动脉造影

目的探讨改良充气压迫法用于经桡动脉CAG患者的效果。方法将择期接受经桡动脉CAG的100例患者随机分为改良组和常规组,每组50例,术后改良组以改良充气压迫法压迫桡动脉,常规组采用常规充气方法压迫桡动脉。比较两组压迫桡动脉2 h、4 h末患者肿胀溢水量及数字疼痛评分,压迫6 h后去掉压迫器时桡动脉穿刺点出血情况以及术后24 h穿刺侧桡动脉闭塞情况。结果改良组压迫桡动脉2 h、4 h末肿胀溢水量、数字疼痛评分均低于常规组(P均0.01)。穿刺点压迫6 h后去掉压迫器时,改良组出血3例,常规组2例;术后24 h改良组桡动脉闭塞1例,常规组2例;组间差异均无统计学意义(P均=1.00)。结论改良充气压迫法可减轻经桡动脉CAG患者术后穿刺侧肢体肿胀及疼痛,且不增加穿刺点出血及血管闭塞危险。

Modified inflatable compression method applied on patients underwent transradial CAG

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.
