Full Answer

What is the proper placement of a central venous catheter?

The steps are as follows:

• Infiltrate the skin with 1% lidocaine for local anesthesia around the site of the needle insertion.
• Use the bedside ultrasound to identify the target vein.
• If using landmarks for the subclavian vein CVL, the needle should be inserted approximately 1 cm inferior to the junction of the middle and medial third of the clavicle. ...

What is a Central Venous Access Device (CVAD)?

• A CVAD is an intravenous line that is put into a large vein in your body and travels to the upper chest
• It can be used to give intravenous medications and chemotherapy and to take blood tests
• Your Central Venous Access Device (CVAD) includes your Hickman or PICC.

What is the purpose of a client having a central venous access device?

Central venous access devices (CVADs) or central venous catheters (CVCs) are devices that are inserted into the body through a vein to enable the administration of fluids, blood products, medication and other therapies to the bloodstream.

What is a central venous device?

A central venous catheter is a thin, flexible tube that is inserted into a vein, usually below the right collarbone, and guided (threaded) into a large vein above the right side of the heart called the superior vena cava. It is used to give intravenous fluids, blood transfusions, chemotherapy, and other drugs.

What are the types of central venous access devices?

Two types of implanted central venous devices are available: tunneled catheters and totally implantable venous access devices, which are placed entirely under the skin tissue (no skin exit site) (figure 1).

Why would a patient have a Cvad?

Common reasons for having a CVAD include: To give IV medicines over a long period of time. An IV catheter can be in a large vein for a longer time than in a small vein. This would be for medicines such as antibiotics and chemotherapy.

Is a central venous catheter the same as a PICC line?

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's the difference between a central line and a PICC 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 PICC line a central venous catheter?

A PICC line is one type of catheter used to access the large veins in your chest (central venous catheter). Examples of other types of central venous catheters include implantable ports and central lines.

How long can a central venous catheter stay in for?

Some central venous catheters are tunneled under the skin so the entry site into the vein is away from the skin entry site. With care, central venous catheters can remain tunneled in the body for several months without becoming infected.

What is a central venous access device?

It’s also called a central venous access device (CVAD) or central venous catheter (CVC). A small, soft tube called a catheter is put in a vein that leads to your heart. When you no longer need the central line, it will be taken out. Your skin will then heal. This sheet describes types of central lines.

Where is the catheter placed in the vein?

Types of central lines include: 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.

What is the name of the thrombus that blocks blood flow?

An air embolism can travel through the blood vessels and block the flow of blood to the heart, lungs, brain, or other organs. Blood clot ( thrombus) that can block the flow of blood.

What are the risks of having a central line placed?

Risks and complications. As with any procedure, having a central line placed has certain risks. These include: Air bubble in the blood (air embolism). An air embolism can travel through the blood vessels and block the flow of blood to the heart, lungs, brain, or other organs.

What is injected near the vein?

Medicine (local anesthetic) is injected near the vein. This numbs the skin so you don’t feel pain during the procedure.

What to do if you have problems with your central line?

If you have any problems with your central line, talk to your healthcare provider.

What is a central line?

What a central line does. A central line is often used instead of a standard IV (intravenous) line when you need treatment for longer than a week or so. The line can deliver medicine or nutrition right into your bloodstream. It can also be used to measure blood flow (hemodynamic monitoring), to draw blood, or for other reasons.

Where does a CVC go?

It goes into your arm or hand. But if you need care for longer than that, you might get what’s called a central venous catheter. It’s also called a central line. A CVC is also a thin tube, but it’s much longer than a regular IV. It typically goes into a large vein in your arm or chest.

What is a port tunneled CVC?

Tunneled CVC. Often when you need medicine, you just pop a pill in your mouth, down some water, and go about your day. But at other times your doctor may need to give you drugs or fluids that go right into one of your veins.

What is the cuff in a catheter?

There’s a cuff in the part that sits in the tunnel, which helps hold the catheter in place. Your doctor then uses stitches to close the cuts and puts a dressing over both.

How do you close a heart tube?

Then, they place the disc end of the port into a pocket between the two cuts. Your doctor closes both cuts with stitches or a special glue called Dermabond.

What is a syringe used for?

They can also be used for taking samples for tests and to give you fluids, nutrients, and blood.

How far out of your chest do you get a CVC?

The other end goes in the tunnel between the two cuts, and the lumens hang 6 to 10 inches out of your chest.

How to secure a CVAD?

A manufactured catheter stabilization device is the recommended way to secure a CVAD. These devices contain an adhesive anchoring pad to help reduce catheter dislodgment and the need for removal and reinsertion. 16,17 However, sterile tape and surgical strips also are acceptable methods of catheter stabilization. Sutures and a dressing alone aren't sufficient. In fact, sutures are associated with needle-stick injuries and should be avoided whenever possible. And because sutures break the skin, they increase the potential for irritation and infection. If a suture site appears inflamed, the sutures should be removed and replaced with a manufactured stabilization device.

Where should a CVAD be placed?

Exactly where the CVAD tip should rest is controversial. Most practitioners prefer to place it in the distal end of the superior vena cava, at or near its junction with the right atrium. Others prefer to place it in the right atrium, as it may cause less fibrin formation, but this position also raises the patient's risk of dysrhythmias. So far, no research has established which site is better; however, national standards of practice, Food and Drug Administration (FDA) guidelines, studies, and CVAD manufacturers' instructions recommend placement in the superior vena cava. Guidance documents from the FDA state that the intracardiac tip location isn't recommended. 2 The Infusion Nursing Standards of Practice recommends that all members of the healthcare team collaboratively address CVAD tip location if the superior vena cava isn't used. 1

What to do after CVAD?

After a CVAD is inserted and before anything is infused through it, verify and document the anatomic location of the CVAD tip. If the CVAD was inserted at the bedside, obtain a chest X-ray. If it was inserted in the radiology department, fluoroscopy may be used to confirm tip location.

How does a catheter related bloodstream infection affect nursing?

Catheter-related bloodstream infections (CRBSIs) take a tremendous toll on patients and eat up nursing time and other healthcare resources. Recent reports suggest that by paying close attention to many aspects of catheter care, you may be able to reduce these infection rates to zero. 3

How to assess patient for insertion site?

When performing your patient assessment, carefully palpate the area around the insertion site through the dressing. If the patient has tenderness or discomfort, investigate for infection. Assess surrounding areas for erythema, warmth, and edema. If the patient has a peripherally inserted central catheter (PICC), assess the entire arm. Erythema, tenderness, and edema could indicate phlebitis or vein thrombosis.

Why do you need to zero in on your role in managing these common I.V. catheters?

Zero in on your role in managing these common I.V. catheters so you can protect your patient from complications.

Where to document CVAD insertion?

If a CVAD is inserted via the femoral vein, obtain a chest X-ray to confirm placement in the inferior vena cava above the diaphragm.

What is central venous catheter?

Central venous catheter insertion is a common and often, necessary procedure for the care of critically ill patients. Central venous access may be attained with various devices, depending on the indication for catheter insertion. Broadly, central venous catheters allow for the administration of vasoactive medications and agents that are known venous irritants but catheters are also used to perform dialysis or plasmapheresis, or as a conduit to insert additional devices for more complex procedures. This activity reviews central venous catheter insertion and highlights the role of the interprofessional team in managing patients who undergo this procedure.

What are the three main access sites for central venous catheter placement?

There are three main access sites for the placement of central venous catheters. 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). A discussion of tunneled catheters and other central access obtained via advanced interventional radiology techniques is beyond the scope of this article. We will focus on the three main sites of access routinely used for short-term (days to weeks) central access.

Why do we use a femoral CVC?

The femoral site is sometimes preferable in critically ill patients because the groin is free of other resuscitation equipment and devices which may be required for monitoring and airway access. Central venous access in the common femoral vein offers the advantage of being an easily compressible site, which may be helpful in trauma and other coagulopathic patients.[25]  Additionally, unlike the IJ and SC sites, iatrogenic pneumothorax is not a concern. Patients may be more comfortable with a femoral CVC because it allows relatively free movement of the arms and legs as compared with other sites. However, femoral CVCs are typically associated with increased thrombotic complications, and likely an increased rate of catheter-associated infections, although studies have shown conflicting results about the true risk of infection when the proper sterile technique is used. [5][26][27][28] Unlike IJ or SC lines, femoral central lines do not allow for accurate measurement of central venous pressure (CVP), though this is not important in every clinical scenario. The common femoral vein is located within the femoral triangle.  This region is outlined by the adductor longus medially, sartorius muscle laterally, and the inguinal ligament superiorly. There are important anatomical considerations to keep in mind when accessing this particular site.  Whereas in the neck, the (carotid) artery is medial to the (internal jugular) vein, in the leg, the artery is lateral to the vein. The mnemonic NAVEL is useful to recall the order of structures from lateral to medial: femoral nerve, femoral artery, common femoral vein, "empty space" (femoral canal), and lymphatics.[29]  It is important to know this anatomy not only for landmark guided central line placement but also because some of these structures may also appear similar on ultrasonography. [11]

How to use manometry for angiocatheter?

In order to do this, an angiocatheter is threaded over the wire, the wire is removed , and the included extension set for the central venous catheter is attached and held upright in the air. The meniscus formed by the column of blood that slowly fills the extension tubing should plateau if the angiocath is in the venous system. However, this method is time-consuming and is not entirely reliable in shock states. Regardless, it can be helpful with the subclavian approach, which is often difficult to fully accomplish with dynamic ultrasound visualization.

How to dilate a venous catheter?

Grasping the dilator in the middle portion, apply gentle, steady pressure, sometimes with a slight twisting motion, in order to dilate the soft tissue and enable passage of the central venous catheter. Approximately 1/3 to 1/2 of the length of the dilator will need to be inserted into the skin/soft tissue space. This depends upon the anatomic site, as well as the specific type of central venous catheter. Dialysis catheters will require several stages of dilation with increasingly larger dilators, and potentially multiple uses of a scalpel to widen the incision.

How to use a finder needle?

Under ultrasound guidance, use the finder needle with a 10 cc syringe attached, at a 45-90 degree angle, advance needle through the skin, holding negative pressure on the syringe until a flash of dark venous blood appears .  Be sure to maintain dynamic visualization of the needle tip as it enters the vessel.

How to prevent bleeding from a guidewire?

Remove the dilator, and place sterile gauze over the site to maintain sterility and minimize bleeding. Again, at no point should the proceduralist lose control of the guidewire.
