Difference between picc, cvc, pvc Answer as follows:
picc (percutaneous central venous catheter):
A long, thin catheter that is inserted through the skin into the body, usually into a large central vein in the upper wrist or upper arm. It is a medical device used for long-term venous access and is usually made of polyurethane or silicone.The PICC is inserted through the skin, extends into the large central vein, and ultimately rests in the superior or inferior vena cava inlet.
1. Location: The PICC line is inserted into the body through a venipuncture through the skin, usually into the large central vein of the upper wrist or upper arm, and ultimately stays in the superior vena cava or inferior vena cava inlet.
2. Application: It is usually used for patients who need long-term intravenous access, such as chemotherapy, infusion, nutritional support or drug infusion.
3.Material: usually made of polyurethane or silicone.
4, maintenance: relatively easy to maintain, usually do not need to be replaced frequently.
cvc (central venous catheter):
It is a thicker, shorter catheter that is inserted into the body, usually surgically or through a puncture, into a large central vein such as the subclavian vein, the internal jugular vein, or the internal iliac vein. cvc is used in situations where high-flow venous access is needed such as in intensive care patients or in patients who need to have their central venous pressure measured. pressure.
1. Location: CVCs are inserted into the body surgically or by puncture into a larger central vein, such as the subclavian, internal jugular, or internal iliac veins.
2. Application: It is indicated for patients who require high-flow venous access, such as intensive care patients, or patients who need to measure central venous pressure.
3. Material: usually made of polyethylene or polyurethane.
4. Maintenance: usually require more frequent maintenance and replacement.
pvc (peripheral venous catheter):
A peripheral venous catheter (PVC) is a short, thick catheter that is inserted into the body, usually through a puncture, and into a peripheral vein, usually in the arm or the back of the hand.PVCs are used for short-term venous access needs such as transfusion of fluids, blood draws, or temporary drug infusions. It is usually made of polyvinyl chloride.
1. Location: PVC is inserted into the body through a puncture into a peripheral vein, usually in the arm or back of the hand.
2. Application: It is suitable for short-term venous access needs, such as infusion, blood draws or temporary drug infusions.
3.Material: usually made of polyvinyl chloride.
4, Maintenance: they usually need to be replaced more frequently because they are prone to complications such as phlebitis.
