Before performing a moderately invasive procedure, such as the insertion of a central intravenous catheter, I would wash and disinfect my hands before putting on sterile gloves and again after the procedure.
A central intravenous catheter is a thin, flexible tube that is usually inserted into the vein below the right collarbone vein and passed through the large vein above the right side of the heart, called the superior vena cava. It is used for infusions, blood transfusions, chemotherapy, and other medications. Doctors may use the central line instead of the regular IV line because it can stay longer in place up to a year.
