目的是评价气囊加压快速静脉滴注在ＣＴ增强扫描中的应用价值。材料与方法采用６０％泛影葡胺或Ｏｍｎｉｐａｑｕｅ（３００ｍｇｌ／ｍｌ）１００ｍｌ造影输血器。常规做碘过敏试验，阴性者穿刺最佳静脉，将血压计气囊连接在胶管上，快速挤压气囊，使空气进入造影剂瓶内，造影剂注入速度达４～５ｍｌ／ｓ。注射前，常规给以１０ｍｇ地塞米松，并将造影剂加热至３７℃左右。尽量减少副反应发生的几率。结果得到了：在没有高压注射器的条件下，采用气囊加压实现静脉团注法。经１４０例增强检查，均一次成功，效果尚满意，可作为小型医院ＣＴ室进行增强检查的种较好方法。但对动静脉各期图像缺乏系统的观察，有待今后进一步探讨。
The purpose is to evaluate the value of rapid intravenous infusion balloon compression in CT enhanced scan. Materials and Methods 100% angiography transfusions with 60% diatrizoate or Omnipaque (300 mgl / ml) were used. Routine iodine allergy test, negative best puncture the vein, the sphygmomanometer balloon connected to the hose, quickly squeeze the balloon, the air into the contrast agent bottle, contrast agent injection rate of 4 ~ 5ml / s. Prior to injection, 10 mg dexamethasone is routinely given and the contrast medium is heated to about 37 ° C. Minimize the chance of side effects. The result was: In the absence of high-pressure syringe conditions, the balloon pressure to achieve intravenous bolting method. After 140 cases of enhanced examination, were successful, the effect is still satisfactory, can be used as a small hospital CT room for enhanced screening of a better method. However, the lack of systematic observation of arteriovenous phase images needs to be further explored in the future.
