摘要
目的:评价单腔静脉留置针在冠状CTA检查中的安全性应用。方法:对2006年1月至2009年12月我院行冠脉CTA检查4600例病人全部采用美国Becton-Dickinson(B-D公司)18-20#单腔静脉留置针注射对比剂,注射速率5-6ml/sec,对比剂浓度350mg/ml。结果:99.8%病例顺利完成冠脉CTA检查,图像质量优良;有0.2%的患者因穿刺技术、血管本身条件差或等待中保护不当造成不同程度渗漏,未完成检查。结论:冠脉CTA检查需高流速、高浓度注入对比剂,其静脉留置针的安全性明显高于传统强化头皮针;同时便于对比剂毒副反应抢救用药。
Objective：To evaluate the safety of using single-luminal indwelling intravenous needle（SLIIN） during coronary computed tomography angiography（CTA）.Methods：From January 2006 through December 2009,coronary CTA was performed in 4600 patients.All the contrast material（concentration：350mg/ml） was injected through No 18 to 21 SLIIN（BD Company,US）,of which the injection velocity was 5 to 6 ml/sec.Results：The CTA was successful in 99.8% cases with an excellent image as a result.However,the examination was unsuccessful in the remaining patients because of failing intravenous puncture,unfavorable veins,or the contrast extravasation owing to the unreliable securing needle before carrying out CTA.Conclusions：SLIIN is securer than traditional intravenous metal needle in the duration of Coronary CTA which required high velocity and strong concentration of contrast medium.Moreover,it is more convenient to administer medication in emergency if the side effects of contrast medium occurred.
