Abstract

Abstract:

Objective To investigate the status of management of iodinated contrast media（ICM） extravasation in Henan Province，as well as nurses’ knowledge and influencing factors，in order to provide a basis for optimizing management strategies. Methods A self-designed questionnaire was applied，employing convenience sampling，to survey nursing administrators and nurses in the radiology departments of 55 tertiary hospitals across 16 regions of Henan Province，from December 2024 to January 2025. Multiple linear regression analysis was conducted to explore the factors influencing nurses’ knowledge. Results A total of 55 nursing administrators and 64 nurses participated，with a valid questionnaire response rate of 100%. The survey results reveal that only 5.45% of radiology departments utilized high-pressure central venous catheters，and 32.73% employed vascular visualization techniques. When setting the high-pressure injection speed for ICM，only 54.55% of radiology departments required an assessment of the type and model of intravenous access. Additionally，only 9.09% of radiology departments mandated an observation for 2 to 4 hours following ICM extravasation. Furthermore，only 50.91% of radiology departments had established an information system for ICM use. The nurses’ knowledge score regarding the prevention and management of ICM extravasation was（90.00±17.59），influenced by years of experience in radiology and professional titles（P<0.05）. Conclusion The prevention and management measures for ICM in radiology departments in Henan Province need further improvement. Nursing administrators should optimize management strategies，improve relevant training systems，and continuously enhance nurses’ knowledge and practical abilities.

摘要：

目的调查河南省含碘对比剂（iodinated contrast media，ICM）外渗管理现状、护士对相关知识的认知水平，并分析认知水平的影响因素，为优化管理策略提供依据。方法自行设计调查问卷，采用便利抽样法，于2024年12月—2025年1月对河南省16个省辖市55所三级医院放射科的护理管理者及护士进行调查，采用多元线性回归分析探究护士对相关知识认知水平的影响因素。结果分别有55名护理管理者、64名护士参与调查，有效问卷回收率为100%。调查结果显示，仅5.45%的放射科使用耐高压型中心静脉通路，32.73%使用血管可视化技术；在设定ICM高压注射速度时，仅54.55%的放射科要求评估静脉通路类型及型号；仅9.09%的放射科在ICM外渗后要求观察2~4 h；仅50.91%的放射科建立ICM使用信息系统。护士相关知识得分为（90.00±17.59）分，放射科工作年限、职称是其影响因素（P<0.05）。结论河南省放射科ICM外渗管理措施有待进一步完善，护理管理者应优化管理策略，完善相关培训体系，不断提升护士的认知水平及实践能力。
