摘　　要：目的:寻找高压静脉注射造影剂时局部疼痛程度最轻的注射部位。方法:将4062例行增强CT检查的患者按静脉穿刺部位分为A组(肘正中静脉组)、B组(前臂头静脉组)、C组(前臂贵要静脉组)、D组(前臂掌侧下段静脉组)和E组(手背静脉组)。静脉穿刺均采用直刺法,分别观察各组注射部位局部疼痛程度。结果:不同注射部位疼痛程度差异有统计学意义(P<0.05)。A组局部疼痛最轻,其次为B、C和E组,D组局部疼痛程度最重。结论:高压静脉注射造影剂时,应尽可能选用血管部位较深、管腔较大和侧支分流量较大的血管,以减轻注射时局部疼痛程度。Aim： To seek an injection site that causes less injection-associated pain during contrast medium delivered into veins with an automated power injector. Methods： A total of 4 062 cases were divided into five groups （A： median cubital vein, B： cephalic vein, C： basilic vein, D： veins of the anterior cubital region, E： veins of the dorsum of hand） according to site of injecting contrast medium into veins. The pain scores at the injection sites were observed in the five groups. Results： The pain scores at the injection sites were significantly different among the five groups（ P 〈 0. 05 ）. The pain was slightest in group A,then was group B,C, and E, and the severest in group D. Conclusion： Deeper and thicker vein with more blood diversions should be chosen to abate the pain during delivering contrast medium into vein.
