Purpose : To propose safe and proper standard of storage and use for contrast by measuring time that temperature reaches to 36℃~37℃ when storing contrast media in a contrast warmer, and checking whether the temperature presented in the contrast warmer and the real temperature is same.
Material and method : We established the temperatures like 37℃ 42℃ and 47℃ differently using the contrast warmer(FINE HNC) for contrast media which is now using and measured the temperatures for thirty minutes on a case-by-case using a digital temperature indicator. First, temperature were measured and compared in the iodine content of the different maker Iobrix350 150ml, Xenetix350 150ml, Omnihexol350 150ml, Bonorex350 150ml. Second, temperature were measured and compared in the Iodine content of different contrast agents Optiray320, Omnihexol350, Pamiray370, lomeron400. Third, temperature were measured and compared in capacity of the storage containersuch as 100ml container, 150ml and 500ml using Ultravist370. Lastly, We measured temperatures When exposed for a long time at room temperature 22℃, 500ml contrast media which similar to a proper temperature.
Result : The temperatures of contrast media were the closest 36℃~37℃ when setting 42℃ by contrast warmer, to use 100ml, 150ml containers in contrast media should be kept before 3 hours, and 500ml should be kept before 4 hours. After 1 hours at room temperature 22℃ when exposed to lower 3℃ in capacity of the storage container 500ml. There was no difference in the iodine content of the different maker and the Iodine content of different contrast agents.
Conclusion : The use of contrast media in proper temperature would be very helpful to reduce side effects by providing viscosity and to minimize the impact on the human body
