PICC (Peripherally Inserted Central Catheter) is a medical device used to administer medications, fluid, blood products, or intravenous therapies over an extended period. It is a long, thin, flexible catheter that is inserted into a peripheral vein, typically in the arm, and guided towards a larger central vein, often the superior vena cava or the right atrium near the heart.
The insertion of a PICC line involves a sterile procedure performed under ultrasound or X-ray guidance to ensure proper placement. The catheter is typically made of silicone or other biocompatible materials to reduce the risk of complications such as infection or phlebitis. It can remain in place for weeks to months, allowing for prolonged treatment without the need for repeated needle sticks.
The PICC line has multiple lumens, or channels, which enable various medications or fluids to be administered simultaneously. The distal end of the catheter protrudes from the arm and is capped when not in use. The proximal end, located near the insertion site, is securely anchored with a dressing.
PICC lines are commonly used in patients who require long-term intravenous therapies, such as chemotherapy, parenteral nutrition, or prolonged courses of antibiotics. They offer several advantages over traditional intravenous catheters, including reduced pain, lower risk of complications, such as damage to veins, prolonged use, and greater ease of administration.
However, PICC lines also carry certain risks, such as infection, blood clots, or catheter misplacement, and should only be inserted and maintained by trained healthcare professionals.
