Application of intravenous management strategies in preventing contrast medium extravasation in radiology department
静脉管理策略在放射科预防对比剂外渗的应用

摘要

目的 探讨静脉管理策略在放射科CT、MRI增强患者中预防比剂外渗的应用效果。方法 成立外渗护理专家小组，基于循证护理模式，实施静脉管理策略：静脉穿刺角度、留置针送管速度、静脉管路固定方法、检查时留置针肢体摆放、对比剂推注前预测试。观察CT、MRI增强检查患者对比剂外渗的发生率。结果 项目实施前后对比剂外渗发生率差异有统计学意义。结论 实施静脉管理策略有效降低放射科增强检查患者对比剂的外渗率，值得临床推广应用。

Abstract

Objective: To investigate the application effect of intravenous management strategy in preventing contrast agent extravasation in patients with enhanced CT and MRI in radiology department.
Methods: An expert group for extravasation nursing was established, and based on the evidence-based nursing model, venous management strategies were implemented: venous puncture angle, indwelling needle delivery speed, venous line fixation method, indwelling needle limb placement during examination, and pre-injection of contrast agent. test. The incidence of contrast medium extravasation in patients with enhanced CT and MRI was observed.
Results: There was a statistically significant difference in the incidence of contrast medium extravasation before and after the implementation of the project.
Conclusion  : The implementation of intravenous management strategy can effectively reduce the extravasation rate of contrast medium in patients undergoing enhanced radiology examination, which is worthy of clinical application.
