Published Apr 12, 2026

A central venous catheter, also known as a central line, is a tube that doctors place in a large vein in the neck, chest, groin, or arm to give fluids, blood, or medications or to do medical tests quickly.

What are examples of central lines?

  • Peripherally inserted central catheter (PICC). This line is placed in a large vein in the upper arm, or near the bend of the elbow.
  • Subclavian line. This line is placed into the vein that runs behind the collarbone.
  • Internal jugular line. …
  • Femoral line.

Is an IV considered a central line?

What Are Central Lines? A central line (or 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. A patient can get medicine, fluids, blood, or nutrition through a central line.

What makes a central line a central line?

A central line is longer, with a larger tube, and is placed in a large (central) vein in the neck, upper chest or groin. This type of catheter has special benefits in that it can deliver fluids into a larger vein, and that it can stay in the body for a longer period of time than a usual, shorter IV.

What is the difference between a PICC line and a central line?

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. PICC stands for “peripherally inserted central-line catheter.” A CVC is identical to a PICC line, except it’s placed in the chest or neck.

Is a midline a central line?

Peripherally inserted central catheters (PICC), which are central lines, and midline catheters, which are peripheral lines, are two types of vascular access devices (VAD) that are used frequently and are often confused with one another.

Can nurses place central lines?

A central line placement is performed in an X-ray room by a radiologist and specially trained nurses and technologists. The radiologist will place a small tube in the vein under your shoulder bone and anchor it by making a small tunnel under your skin.

Why put an IV in the neck?

The catheter is guided through the veins until it is positioned in the large vein (superior vena cava) leading to the heart, where blood flow is fast. This placement allows for better mixing of medicines and IV fluids. The rest of the CVL is tunneled under the skin, from the neck to the chest area.

Can you draw blood from central line?

Blood draws via central line catheters may be performed only by RNs trained in central line. 4. This procedure shall be done using aseptic technique.

Where should you not insert a central line?

Contraindications include distorted local anatomy (such as for trauma), infection overlying the insertion site, or thrombus within the intended vein. Relative contraindications include coagulopathy, hemorrhage from target vessel, suspected proximal vascular injury, or combative patients.

Is a port a central line?

An implanted port 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 vein is a central line placed in?

A central venous catheter (CVC) is an indwelling device that is peripherally inserted into a large, central vein (most commonly the internal jugular, subclavian, or femoral), and advanced until the terminal lumen resides within the inferior vena cava, superior vena cava, or right atrium.

Can a PICC line be in the chest?

A PICC line is one type of catheter used to access the large veins in your chest (central venous catheter).

Is a Hickman line a central line?

A central line is a long, thin, hollow tube made from silicone rubber. They are also called skin-tunnelled central venous catheters. But you may hear them called by brand names such as Hickman® or Groshong® lines. They are used to give chemotherapy treatment or other medicines.

Is a triple lumen catheter a central line?

Triple-lumen catheter The most commonly used catheter for central venous access is the triple lumen catheter. They are preferred (particularly in the ICU) for their three infusion channels that allow for multiple therapies to be administered simultaneously.

Is a tunneled dialysis catheter A central line?

There are several types of central venous access catheters: Tunneled small-bore catheters, which are often referred to as Hohn, Hickman, or Broviac catheters, are frequently used for infusion of antibiotics or other medications, nutritional supplements, and chemotherapy treatments.

What is the difference between a central line and an arterial line?

Arterial lines are different from central lines in several ways. The most obvious difference is that the cannulation is of an artery instead of a vein. As with central line insertion, there are clear indications for the insertion of arterial lines.

How do you prevent a central line infection?

  1. Use appropriate hand hygiene.
  2. Use chlorhexidine for skin preparation.
  3. Use full-barrier precautions during central venous catheter insertion.
  4. Avoid using the femoral vein for catheters in adult patients.
  5. Remove unnecessary catheters.

How long can you leave in a central line?

Central venous catheters may be used for the following reason: To give medicines for treatment of pain, infection, or other medical issues (e.g., cancer or heart problems) To provide fluids for nutrition. To help conduct certain medical tests.

Why can't you draw blood from a Midline?

There is a small risk for infection. The longer the midline catheter is in place, the greater the risk. Bleeding and bruising at the site of insertion. Inflammation of the vein (phlebitis).

How do you know if it is a PICC or Midline?

A PICC catheter is applied through a vein located in one arm. This is then guided along the larger vein to your chest. On the other hand, a midline catheter is inserted through the upper arm or the elbow region. PICC lines are longer than midline because of the regions that they pass through.

How can you tell the difference between a PICC line and a Midline?

PICC lines are placed into a vein in your arm, and then guided into a larger vein in your chest. A midline catheter is put into a vein by the bend in your elbow or your upper arm. The midline catheter tube is shorter than a PICC line. The midline tube ends in a vein below your armpit.

Do you flush a central line?

A central venous catheter must be flushed every day to keep it clear of blood and prevent clotting. If it ends in more than one line (lumen), flush them in the same order each time. Depending on the type of CVC you have, you will flush it with either heparin or saline solution.

Do you flush a central line before drawing blood?

To maintain patency, flush all CVCs before and after access and infusion. You can draw blood from a CVC using the discard method with direct Vacutainer connection or a syringe or using the push-pull method with a syringe.

Can you draw blood from a UVC?

A UVC is used to give necessary intravenous fluids and medications. A UAC is used to draw blood for tests without causing pain and monitor blood pressure without disturbing the baby.

What is the most common immediate complication of central line insertion?

Cardiac complications: Cardiac complications are considered to be one of the immediate complications seen in a central line insertion. Physicians will encounter arrhythmias during or as an immediate result of the insertion because of the guide wire coming into contact with the right atrium [14].

Can you draw blood from a human jugular?

Ideally, blood should be collected from the jugular, as this generally allows for better sampling. However, if a patient is known to have a coagulopathy (clotting dysfunction), blood samples should then be taken from the saphenous (either lateral or medial) vein or the cephalic vein.

What vein does an IV go into?

The three main veins of the antecubital fossa (the cephalic, basilic, and median cubital) are frequently used. These veins are usually large, easy to find, and accomodating of larger IV catheters. Thus, they are ideal sites when large amounts of fluids must be administered.

Which central line insertion site has the highest risk of infection?

The short answer is: yes, femoral central venous catheters (CVCs) have the highest rates of infection and thrombosis according to current literature, but both complications are associated with long-term insertion.

When would you use a central line?

Purpose of a Central Line If a patient needs fluid resuscitation, meaning large amounts of intravenous fluids need to be given, a central line may be placed to allow fluid to flow faster. Central lines can be used to draw blood as well.

How far should a central line be inserted?

Based on the mean distance from the CVC insertion point to the distal SVC, we determined that the recommended depth of insertion should be 14 cm for the right subclavian vein, 15 cm for the right internal jugular vein, 17 cm for the left subclavian vein and 18 cm for left internal jugular vein.
