A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...

On anteroposterior X-rays, a catheter tip between 55 and 29 mm below the level of the carina is regarded as acceptable placement. [37] Electromagnetic tracking can be used to verify tip placement and provide guidance during insertion, obviating the need for the X-ray afterwards.
One of the PICC insertion risks is median nerve damage, and a conscious patient will immediately report tingling, numbness, or an electric shock feeling if the insertion needle is near a nerve. If the patient is under general anaesthesia, they are not aware of any of this and severe (possibly irreversible) nerve damage can result.
A catheter embolism may occur when a small part of the cannula breaks off and flows into the vascular system. When removing a peripheral IV cannula, the tip should be inspected to ensure it's intact. [5] Because of the risk of insertion-site infection the CDC advises in their guideline that the catheter needs to be replaced every 96 hours. [6]
Blood is aspirated from the catheter to confirm the position. Then, the free-end of the port catheter is inserted through the peel-off sheath. After the tip of the port catheter is confirmed at the aortocaval junction, the peel-off sheath is taken-off by peeling away with two hands. While peeling off, the port catheter should remain in-situ.
