peripherally inserted central catheter (PICC) care, a nursing intervention from the Nursing Interventions Classification (NIC) defined as insertion and maintenance of a peripherally inserted central catheter either midline or centrally located. See also Nursing Interventions Classification.
Midlines are used for medications or fluids that do not irritate veins. PICC stands for peripherally inserted central catheter. It is put into a large vein in the arm and ends in a large vein near the heart. Sometimes a leg vein is used for infants. A PICC can be used for longer periods of time than a midline.
