I haven't seen any posts on this, it seems to be a rare problem. I thought my husband's experience might help someone else. He had a Picc line inserted at MDA and received first chemo. I was taught to flush and dress the insertion point. After he was discharged, we drove 9 hours home. When he removed his shirt, the dressing was wet. It was a gauze type dressing with a wide band of adhesive at the edges. I changed the dressing and the next day it was stained and damp again. When I changed it again, I could see that the skin under the adhesive area was red. We went to our local oncology office and they switched him over to a 4 x 4" Tegaderm that includes a non-adhesive pad over the insertion point. Next day we could see fluid under the clear plastic. Returned to oncology office where they switched to 2 small Tegaderm patches with sterile gauze to protect the insertion and allow inflammed skin to dry out, and started him on Bactrim to bring down the swelling and redness. Fluid oozing continued, so the Picc line was replaced, old line was tested without being able to find a leak. Overnight, more fluid accumulated inside the Tegaderm patch, and now the skin outside the dressing is healing, but the skin under the patch is getting red. Rather than call the professionals, I searched on line and found a site for cystic fibrosis and another for nurses that discussed weeping skin around a picc line and adhesive allergy. Found 2 similar suggestions which I have followed and now 5 days later his skin is clear.
1) Place a bio-patch over the insertion point, hold it in place by lightly taping to the butterfly. Cover with 4 x 4" sterile gauze, tape corners and change daily.
2) Place 2 x 2" sterile gauze over the insertions point. Hold in place by lightly taping to the butterfly. Cover with 4 x 4" sterile gauze, tape corners and change daily.
I have alternated between the biopatch and the all gauze dressing. I found that when paper tape or 3M micropore tape got wet, it was very difficult to remove and irritated his skin. I use the same Nexcare flesh colored waterproof tape that I use to make Press and Seal waterproof for showering. It sticks beautifully and releases instantly with no pain or irritation. We now know that he has interstitial fluid seeping from the insertion point. As the inflammation dimenishes and the skin around the cather closes up, we see less and less fluid on the gauze. When you are dealing with high grade muscle invasive BC with probable lymph involvement and just starting chemo, this is relatively minor, but it felt like a crisis that was going to push us over the top. Hope this may help someone else.
