摘要
目的探讨总结婴幼儿CT增强扫描的技术特点。方法选取受检患儿30例，造影剂为非离子型造影剂欧乃派克，镇静催眠药物10％水舍氯醛或安定，剂量按公斤体重计算。结果30例中，28例一次检查成功，2例首次检查患儿无法镇静入睡，再次检查成功。结论婴幼儿属于高危人群，在CT增强扫描中，正确使用造影剂，合理应用镇静催眠药物，作好造影剂过敏反应的预防和急救工作，可降低婴幼儿造影剂过敏反应的发生率。
Objective To research and summary the technic behavior of CT contrast enhancement scanning about infants. Methods 30 infants were chosed to have a test. CT contrast enhancement with ornnipaque,one of the non - ionic contrast media, All the infants were calmed with Chloral Hydrate（ 10% in Concentration or Diazepam）. These doses of the drugs were determined by the weight of these infants. Results 28 cases of infants were checked successfully for the first time in 30 cases. Other 2 cases of infants couldn＇t be poised to sleep for the first time, hut they were poised to sleep and checked successfully for the second time. Couclusion Infants belong to high - vish group. It must be strict to grade of suitabte sign and coutraindication. It must be ready for all kinds of work before or after scanning, and select safer hyposmolality nonionic iodin coutrast medium. It must be ready for prevention and first aid of allergic reaction of contrast medium. All the above can decrease the incidence of infants contrast medium allergic reaction.
