监视器在CT增强检查中的应用价值

目的:评估监视器在监测增强CT扫描时对比剂外渗中的价值。方法:患者随机分采用监视器组(A组)和未用监视器组(B组),A组8603例,B组7985例,设定对比剂渗出>50ml为重度外渗,对比剂渗出<10ml为轻度外渗,观察A、B两组皮下对比剂外渗程度。结果:A组发生轻度外渗45例,重度外渗1例,B组发生轻度外渗33例,重度外渗18例。两组比较,其差异具统计学意义(P<0.05)。结论:应用监视器可早期发现穿刺、注射处的异常现象,从而防止重度对比剂外渗的发生。

Application of Monitor in the Detection of Contrast Agent Extravasation During Contrast Enhanced MSCT Scanning

Objective:To study the value of monitor for the detection of contrast agent extravasation during MSCT scanning.Methods:16588 patients were randomly divided into 2 groups.There were 8603 patients in group A(applying monitor),and 7985 patients in group B(control group).Mild extravasation was diagnosed when the volume of extravasated contrast agent was less than 10ml,and severe leakage was diagnosed when the volume of extravasated contrast agent was more than 50ml.The degree of subcutaneous contrast agent estravasation was observed and compared.Results:In group A,severe contrast agent extravasation was found in 1 patient and mild extravasation in 45 patients,whereas in group B,severe extravasation was found in 18 patients and mild extravasation in 33 patients.Statistical difference was existed(P<0.05).Conclusion:Monitor can be found the early abnormal phenomenon of puncture and injecting,preventing the severe contrast agent extravasation.
