摘要
目的寻求高压静脉注射造影剂外渗发生率较低的注射部位,以减少渗出的发生率。方法将穿刺部位分为肘正中静脉组（A）、前臂头静脉组（B）、前臂贵要静脉组（C）、前臂掌侧静脉组（D）和手背静脉组（E）五组。静脉穿刺针头与皮肤呈60°角进皮肤后直接进入血管,并血管内潜行6-10 mm,注射速度2.5-3ml/s。结果各组局部渗出发生率之间差异有统计学意义（P≤0.010）;A组（0.31%）、B组（0.50%）和C组（0.78%）的局部渗出发生率差异无统计学意义;D组（1.38%）和E组（2.3%）的局部渗出率差异也无统计学意义。A组、B组和C组注射造影剂渗出率较低。结论上肢注射部位血管直径越大、侧支血液分流量越大、渗出率越低。
Objective To seek a less frequencies of contrast material extravasation at the injection site during contrast material delivered into veins with an automated power injector. Methods Five groups （A： median cubital v, B： Cephalic v, C： basilic v, D： veins of the anterior cubital region, E： veins of the dorsum of hand）were divided according to the site of injection of contrast media. Pinhead with skin shaped at 60° clamp when venipuncture was implemented and the pinhead penetrated into skin immediately intoveins and followed the veins 6- 10 mm. Contrast material was injected at rates 2.5-3 ml/sec. Results Extravasation rates at the injection sites were significantly differ- ent among the five groups （P≤0. 010） . Extravasation rates weren＇t different significantly among group A （0.31%） , B （0. 50%） and C （0. 78%）, and weren＇t different significantly between group D （1. 38%） and E （2.3 % ） . Extravasation rates of group of A, B and C were significantly lower than group D and E. Conclusion The thicker veins and more blood diversion of injection of contrast material at upper limbs, the lower extravasation rate.
