After removal, the insertion site is normally bandaged with sterile gauze and kept dry for a few days, during which the wound can close and begin healing. Usually, a smaller adhesive bandage can be placed over the wound site after the gauze is removed if the wound is slow to heal. The tip of the catheter is sent for MCS (microscopy culture and sensitivity) if the patient is systemically unwell at the time of removal of the PICC.
