目的 探讨离子型造影剂加入地塞米松在CT增强中预防或减少过敏及毒副反应效果。方法 回顾性分析 2 480例患者中观察组 1860例用离子型造影剂加入地塞米松 ,两药混均后经肘静脉注入进行CT扫描。结果 2组结果表明 ,过敏及毒副反应发生率轻度反应观察组比对照组降低 3 .1%,中度反应率对照组 1.4%,观察组 0 .5 %。结论 离子型造影加地塞米松在CT增强的应用中预防或减少过敏及毒副反应研究是切实可行的措施之一。
Objective To investigate the effect of dexamethasone on the enhancement of CT in preventing or reducing allergy and toxic side effects by adding ionic contrast agent. Methods A retrospective analysis of 2 480 patients in the observation group of 1860 patients with ionic contrast agent added dexamethasone, two drugs mixed by the elbow vein for CT scan. Results The results of two groups showed that the incidence of allergic reaction and toxicity were lower in the observed group than in the control group by 3.1%, the moderate response rate was 1.4% in the control group, and the observation group was 0.5%. Conclusion Ionic contrast plus dexamethasone is one of the feasible measures to prevent or reduce allergy and toxicity in the application of CT enhancement.
