A central line, or central venous catheter, is like an artificial vein. It will make it easier for your healthcare team to access your blood vessels for medications and tests. Central lines can collect bacteria and cause infection. If you have a central line and have a temperature of 100.4° F (38 ° C) or higher, or you have redness, swelling, or tenderness at the catheter site, call your doctor as soon as possible.
