中心静脉导管高压注射碘对比剂的安全性研究进展

Advances in safety of high-pressure injection of iodine contrast media via central venous catheter

CT增强检查时必需通过血管通路高压注射碘对比剂,但在急危重症或血管条件特别差的患者常常无法选择到外周血管通路进行高压输注,中心静脉导管将是另一条注射途径。本文就中心静脉导管高压注射碘对比剂安全性的国内外研究进行综述,为穿刺特别困难的患者输注通道的选择提供参考依据,为下一步的深入研究提出指导性建议。

High-pressure injection of iodine contrast media(ICM)through vascular access is a necessary step in contrast-enhanced CT,but it is hard for patients with severe and acute diseases or especially-bad vascular conditions to reach peripheral vascular access. Therefore,central venous catheter can be an alternative. This paper reviewed studies at home and abroad concerning the safety of high-pressure injection of ICM via central venous catheter,providing a reference to infusion channels for patients with particularly difficult puncture and a guidance for further research.
