What did I suggest?
I suggested that discontinuing antibiotics was appropriate.
It didn’t make sense that this was a non-responding cellulitis of his arm. He had also had some cefuroxime in the ICU (not sure of the indication) and this developed while on it. The “look” isn’t typical of cellulitis and the distribution is very suspicious for a response to extravasation of some infusion he received in ICU.
Antibiotics were discontinued and it resolved over the next several days.
Not all acute inflamed areas of skin are cellulitis.
