What does PICC mean?

A PICC (Peripherally Inserted Central Catheter) is a medical device used for long-term intravenous therapy. It is often used for patients who cannot be treated by conventional venipuncture, such as cancer patients, patients on long-term infusions, or patients who need repeated blood tests.

A PICC is a thin, flexible, bendable catheter usually made of polyurethane, silicone, or other biocompatible materials. It inserts the catheter through a superficial vein in the arm or leg and gradually works its way up the venous line until it reaches a large vein near the heart, such as the superior or inferior vena cava.

The use of a PICC has the following advantages:

1. Protection of the vein: A PICC reduces damage to the patient's blood vessels and reduces the risks associated with routine venipuncture.

2. Improve the efficiency of infusion: Since the PICC is located in the central vein, the drugs can enter the blood circulation faster and improve the therapeutic effect.

3. Reducing the risk of infection: Since the PICC is inserted deeper, it can reduce the risk of infection and improve patient safety.

4. Facilitate patient activities: The PICC has a shorter exposed portion on the body surface, which facilitates the patient's daily life and activities.

However, PICC may also bring certain risks and complications, such as catheter blockage, phlebitis, and catheter displacement. Therefore, when deciding to use a PICC, patients should fully communicate with their doctors about the risks and precautions involved. Meanwhile, after PICC placement, patients need to follow the doctor's recommendations for catheter maintenance and care to ensure the safety and effectiveness of treatment.
