目的通过不同型号静脉留置针的临床应用,探讨静脉留置针对炫速双源CT冠脉成像的影响.方法将120例患者随机分为3组各40例,分别选用18G、20G、22G留置针穿刺,行CT冠脉成像,测量左冠状动脉和右冠状动脉开口处、右静脉开口平面及右心室腔CT值,并比较患者穿刺时疼痛感.结果 120例患者均完成检查,18G与20G对比和18G与22G对比:左右冠状动脉强化值和右心室的CT值比较差异均有统计学意义;20 G与22 G对比,所有监测点强化值均无统计学意义;三组右冠状静脉断面的CT值比较差异均无统计学意义.结论选用20G型号留置针能获得最佳的炫速双源CT冠状动脉图像,且患者的认可度较好.

Objective To investigate the effect of the choice of the different models of venous indwelling needle on coronary flash dual-source computed tomography (CT) angiography.Methods 120 patients were randomly divided into three groups (40 cases in each group) who were selected to use 18G,20G,22G indwelling needle.They underwent CT coronary imaging.We measured the CT value of left and right coronary artery opening,right vein opening plane and the right ventricular cavity.We also compared the pain of patients during puncture.Results 120 cases were completed inspection.There was significant difference in the strengthen value of left and right coronary artery and CT value of the right ventricle cavity between 18G and 20G.The difference in the strengthen value of left and right coronary artery and CT value of the right ventricle cavity between 18G and 22G was also significantly different.There was no significant difference in all monitoring points between 20G and 22G.Three types of right coronary vein were not statistically significant.Conclusions Model 20G indwelling needle get the best flash dual-source CT image and better patients' acceptance.
