What is the difference between central line and peripheral line?


A peripheral IV line (PIV, or just “IV”) is a short catheter that’s typically placed in the forearm. It starts and ends in the arm itself. A PICC line is a longer catheter that’s also placed in the upper arm. Its tip ends in the largest vein of the body, which is why it’s considered a central line.

What is the difference between central and peripheral vein?

Peripheral venous access is indicated for the administration of fluids, drugs, or if nutrients when other routes are unavailable. Central venous access is indicated if peripheral access is unsuccessful or if hypertonic, irritant, or vasoconstrictor solutions are used.

Why use a central line instead of a peripheral line?

Doctors might use a central line instead of a regular IV line because: It can stay in place longer (up to a year or even more). It makes it easier to draw blood. Patients can get large amounts of fluids or medicines (like chemotherapy) that might not go through regular IVs.

What is a peripheral line used for?

Overview. A peripheral intravenous line is a small, short plastic catheter that is placed through the skin into a vein, usually in the hand, elbow, or foot, but occasionally in the scalp. A peripheral intravenous line is used to give fluids and medications to your baby.

Can you give blood through a peripheral line?

Background. Sampling blood from a peripheral intravenous cannula offers an alternative to venepuncture. This practice can reduce frequency of venepuncture and patient discomfort. Opponents argue the practice increases the chance of haemolysis, risk of infection and device failure.

Which vein is used for central line?

The internal jugular vein, common femoral vein, and subclavian veins are the preferred sites for temporary central venous catheter placement. Additionally, for mid-term and long-term central venous access, the basilic and brachial veins are utilized for peripherally inserted central catheters (PICCs).

Can you draw blood from a central line?

Many vascular lines, including various types of central lines, peripheral IVs, and arterial lines can be used for sampling blood. However, even if the patient has a line, it is possible to collect blood using venipuncture or fingerstick.

What are the 3 main types of vascular access devices?

Vascular Access Device (VAD): Any device utilized for venous access regardless of location. These include peripheral intravenous catheter (PIV), peripherally inserted central catheter (PICC), centrally inserted central catheter (CICC), and implanted venous port.

HOW LONG CAN peripheral IV stay in?

Background: US Centers for Disease Control guidelines recommend replacement of peripheral intravenous catheters (PIVC) no more frequently than every 72 to 96 hours. Routine replacement is thought to reduce the risk of phlebitis and bloodstream infection.

Why is peripheral IV given?

Peripheral intravenous catheters (PIVC) are the most commonly used intravenous device in hospitalised patients. They are primarily used for therapeutic purposes such as administration of medications, fluids and/or blood products as well as blood sampling.

Is a PICC line central or peripheral?

A peripherally inserted central catheter (PICC line) is a type of central line. A central line (also called a central venous catheter) is like an intravenous (IV) line. But it is much longer than a regular IV and goes all the way up to a vein near the heart or just inside the heart.

What is a peripheral vein?

The peripheral veins of normal persons are distensible vessels that contain approximately two-thirds of the total blood volume and can accept or donate blood with relatively little change in pressure.

Where is the central vein located?

In microanatomy, the central veins of liver (or central venules) are veins found at the center of hepatic lobules (one vein at each lobule center).

Is cephalic vein central or peripheral?

The objective of this study was to determine the agreement between cardiac output measured by central (cranial vena cava) versus peripheral (cephalic vein) venous injection of lithium chloride for lithium-dilution cardiac output (LiDCO) determination in the dog.

Is the external jugular vein a central line or a peripheral line?

The external jugular vein is considered a peripheral vein and it is consistent with the RN scope of practice as outlined by the Infusion Nursing Society and the Infusion Nurse Standards of Practice, to ensure safe practice and continuity of care for patients.

Why can’t you take blood from a cannula?

Avoid taking blood from a peripheral cannula that is already in situ as this may collapse / damage the vein or affect the sample through haemolysis, dilution or contamination.

How often should a peripheral IV be changed?

US Centers for Disease Control guidelines recommend replacement of peripheral intravenous catheters (PIVC) no more frequently than every 72 to 96 hours. Routine replacement is thought to reduce the risk of phlebitis and bloodstream infection.

Can a nurse insert a central line?

It is NOT within the scope of practice of the Registered Nurse (RN) to insert a central venous catheter (CVC) through the use of the subclavian vein or to insert any catheter using a tunneled or implanted approach.

Who needs a central line?

A central line is necessary when you need drugs given through your veins over a long period of time, or when you need kidney dialysis. In these cases, a central line is easier and less painful than having needles put in your veins each time you need therapy.

How many types of central lines are there?

Three common types of CVC are a tunnelled central venous catheter, a peripherally inserted central catheter (PICC) and a subcutaneous (implanted) port. Your doctor will recommend the type of CVC you should have based on your situation and how long the CVC may be needed.

What happens if you dont clamp IV?

Connection tubing that has a clamp on it can help keep the PICC from clotting. If you take the syringe off the needleless connector with the tubing unclamped, a small amount of blood will be sucked into the catheter. Over time, this can cause blood to clot in the PICC line, and stop working.

Which vein is used for IV?

Median antecubital, cephalic and basilic veins These veins are the preferred sites for insertion of percutaneous central venous catheters.

What happens if IV is not in vein?

When an IV is not inserted properly or is otherwise misused, fluids or medicine can leak into the surrounding tissue. This is called IV infiltration, and it can cause harm ranging from irritation to fluid overload, infections, nerve damage, stroke, brain injury, or even death.

What do you flush a peripheral IV with?

One (1) syringe of sterile sodium chloride (saline for IV use).

When should a peripheral cannula be removed?

6.4 Peripheral intravenous cannula must be removed immediately if complications occur, or if no longer required for intravenous medications and/or fluids (i.e. not used for over 24 hours). They should be insitu for 72 hours (or manufacturer’s recommendations).
