Be Aware Of Poison I.V. In Your Arm. The next time you’re in the hospital and need an intravenous tube in your arm, be aware that you might be at risk.
The Journal of General Internal Medicine points out that those intravenous lines are held in place with adhesive tape, and 74 percent of those pieces of tape are carrying colonies of possibly harmful bacteria.
Tape Roll May Have Bacteria
So make sure the nurse tears off the outer layer of the tape and throws it away. Even though the outside of the tape roll may have bacteria on it, the inside of the tape is almost always safe to use.
