If bacteria start to grow on the central line catheter, they can easily enter the blood and cause a serious infection. This can lead to a condition called
sepsis, which occurs when bacteria overwhelm the body.
Bacteria normally live on the skin. These bacteria will sometimes track along the outside of the catheter. From the catheter, they can get into the bloodstream.
Factors that may increase your chance of a CLABSI: Having a catheter for a long timeHaving a catheter that is not coated with an antimicrobial—a substance that kills bacteriaHaving a catheter inserted into a vein in the thighHaving a weakened immune systemBeing in the intensive care unitHaving an infection elsewhere in the body or skin
CLABSI may cause: FeverChillsFast heart rateRedness, swelling, or tenderness at the catheter siteDrainage from catheter site
