Proper treatment for contrast media extravasation into tissues around a vein includes?

1. Application of cold wet towel to affected area

2. Application of moist heat to affected area

3. Application of pressure to injection site

4. Application of ice pack to affected area

The correct answer is: Application of ice pack to affected area

Contrast media extravasation occurs when the contrast medium gets infiltrated into the tissue surrounding the vein instead of entering the bloodstream. The appropriate first response to this situation is to apply an ice pack to the affected area. This method is effective because the cold temperature helps to constrict the blood vessels, which can reduce swelling and pain. It also minimizes the inflammatory response that can occur due to tissue irritation from the contrast media. The application of ice does not only aid in the management of pain but also potentially limits the spread of the extravasated contrast material. By cooling the tissue, ice can help slow down the metabolic processes that lead to further inflammation or damage. Using moist heat or a wet towel can increase blood flow to the area, potentially exacerbating the swelling and discomfort. Applying pressure to the injection site can also be counterproductive, as it may not effectively help in managing the extravasation and could cause more tissue trauma. Thus, using an ice pack is the most beneficial initial approach to treat extravasation of contrast media.
