Allergic reaction to ????

So yesterday, Nurse D. came over and change the IV access for Jagger, as we cannot keep the needle in for more than a week.
It is quite an ordeal to change the access. It has to be sterile, so anyone helping or neat Jagger when it is change ahs to wear mask and gloves.
The area has to be clean with Chlorostep for 30 seconds then air dry before the needle can be inserted into the port. And if you know Jagger that is the hardest part has it is impossible to get him to stay still for more than 5 seconds so we have to hold his arms during this part of the procedure.
Then it has to be tape very well as you can not leave any opening for possible infection to get in his body.
Anyhow, we notice he was having a reaction this last night, btu it got worst overnight. He did it to a smaller extent at the hospital but this is really bad. We actually had to give him some morphine last night so he coudl sleep.

I am posting a pic to show how bad the reaction was. Nurse D. thinks it is the Chlorostep, but I am not sure if it is not a combination of that and the tape too.
Anyhow, Nurse D. came by and took the needle out and order a steroid cream to stop the swelling and redness. Since he has been getting nearly enough fluid thru the G tube we are going to try to hold off for a few days and not have to access the port until next week so his skin can heal
