Redness and Bumps After MRI Cannula Insertion

Livingasazebra

I got a cannula put in for an MRI scan on Tuesday. By last night (Friday) I noticed I got redness and like tiny little bumps around the cannula site. By much later on that night it got itchy. It still itches a lot and is red/bumpy. Is this an infection or what? I searched it up and ppl said it would clear on its own but I want to ask here has anyone had this before and did it go away or was it an infection?

      I'm allergic to the dye used for MRI scans. The cannula itself is not a problem. The tape causes irritation and a rash but the dye used for contrast in the scan causes a more severe reaction for me. I get swelling, itching and hives all over.

      Yeah, I had to wear medical tape on the same bits of skin for two months last fall when I got badly burned. The adhesive tugs on the skin and irritates it, so after multiple days it causes dermatitis. Definitely don't itch it and be super gentle with the skin, if it's irritated it can start weeping like an open wound. Ice packs and allergy medicine help a ton with the discomfort! Cold feels sooooo good!!! Having fans blowing on my skin helped me sleep with the itchiness. Anti-itch cream helps too but try to avoid ones with hydrocortisone. If you start getting full body hives or red streaks in your skin around the cannula site or pus that's all signs of things that need medical attention.

      I get this every time due to intolerance to latex and adhesives

      I've had this before!! I actually don't know what it is, my mom thought it was an allergic reaction to the adhesive, but we're both not entirely sure. Try not to touch it or itch it, the way I prevented this is using nasal spray around the area you plan to put the adhesive on! It worked immediately and after a while of using it, I didn't need it anymore!! Just don't itch it, trust me!!

        @tanaka I agree, my roommate is a nurse and she's told me that people get irritation rashes and allergic reactions to adhesive all the time. Especially if you've had that adhesive on for multiple days.

It is possible that the redness and bumps around the cannula site could be a mild allergic reaction or irritation from the tape or cannula itself. Some people have mentioned similar experiences, and it usually clears up on its own. However, if the area becomes very warm, swollen, or increasingly tender to touch, it might be a sign of infection, and you should consult a healthcare professional.
