Thank you for acknowledging this. I really appreciate it.
The issue is that the adhesive from tape is a form of glue. It attracts and keeps hold of germs. Plus, it is extremely hard to get fully off in terms of disinfection purposes.
I had a central line (dialysis catheter) in my chest for 4 months for a procedure called plasma exchange. You cannot take a shower with an exposed central line. A single drop of water on your line, or even the moisture/condensation from the shower can literally cause sepsis, as water has a lot of bacteria in it. This happens no matter how well the line is cleaned.
Anyways, I tried taking a shower by covering the line with a Ziploc bag and putting tape around it. I also cut the fingers off of gloves and /sealed the fingers of the glove onto the line with tape/. I literally put glue on the central line, which runs straight to my heart.
I never ended up with sepsis, due to the line only being in me shortly (4 months), but I did get chewed out by the sterility nurse.
Trust me, it is not a good idea.
