是探讨ＣＴ增强扫描中降低造影剂副反应的基本原则和处理措施。材料和方法：对１８００例ＣＴ增强扫描病例进行造影剂应用的选型和预防性给药，对其中出现的造影剂副反应进行分类、记录和总结并提出具体的处理措施。结果：应用离子型造影剂副反应发生率为５．０４％，应用非离子型造影剂副反应发生率为０．９％。结论：合理选择造影剂、严格筛选高危人群和预防性给药以及完备的抢救措施能明显降低造影剂的副反应率和致死率。
Is to explore the CT enhanced scan to reduce the contrast agent side effects of the basic principles and treatment measures. Materials and Methods: 1800 cases of contrast-enhanced CT scan selection and prophylactic administration of contrast agents, which appeared in the contrast agent side effects classified, recorded and summarized and put forward specific measures. Results: The incidence of adverse reactions was 5.04% with ionic contrast agents and 0.9% with nonionic contrast agents. Conclusion: Reasonable choice of contrast medium, strict screening of high-risk groups and prophylactic administration and complete rescue measures can significantly reduce the contrast agent side effects and mortality.
