Mine stayed on for six weeks before being replaced, but mine was outside of the tegaderm dressing. My PICC catheter is blue, and there is almost ten cm extending from the insertion site.

This is held in place with Steristrips (sterile pieces of tape) and the clear tegaderm dressing on top. The tegaderm is like a big piece of cellophane that covers the entire site to keep things sterile.

At the edge of the tegaderm is the connection for my Statlock, which is an additional means of securing the line. Not everybody has a Statlock put on, and my nursing company didn't even have new ones to change mine. But it is the most secure way of keeping the line from moving.

I keep a roll of surgical tape around to stick on anything that starts to lift up. I'm not sure what part of your PICC keeps coming off, but you should let the health care company know if it isn't staying in place.

Keep the line in place is one of the most important things to keep the line sterile and prevent infection.

Is the entire thing coming off, or just the edges? When I use the tape over it, it seems like the adhesive starts to grab on again, and I can take the extra tape off for a few days.

Of course, this only works if your Statlock is outside the sterile dressing. Also, I found I have the least reaction to paper tape. Some of the plastic ones give me really bad rashes.

I have been on IV treatment for the last 19 weeks. For the first six weeks or so the nurse used a tegaderm dressing. However, over time we noticed that the tape was causing skin tears and irritations. So my nurse switched me over to a sorbaview 2000 dressing. I have had wonderful results with this dressing. We no longer use tape or steri strips within the sterile field or around the outside of the dressing. However, we still use tape and a piece of gauze to anchor down the IV extension tubing so that it does not dig into my skin. Perhaps it might be worth asking your nurse about trying a sorbaview 2000 dressing. Wishing you all the best.
