Study Notes

Central Venous Access Devices (CVADs)

CVADs are catheters placed in large veins (subclavian, jugular, or femoral) for frequent, long-term, or specialized vascular access.
Examples include chemotherapy, antibiotics, hemodialysis, and nutritional support.

Advantages of CVADs

Immediate access to the central venous system.
Reduced venipuncture frequency.
Access for patients with limited peripheral access.
Hemodynamic monitoring capabilities.

Disadvantages of CVADs

Increased risk of infection, including central line-associated bloodstream infections (CLABSIs).

Types of CVADs

Centrally Inserted Catheters

Tunneled or non-tunneled.
A dacron cuff stabilizes the catheter.
Used for long-term access.
The catheter tip is placed in the superior vena cava.
Lower risk of infection compared to non-tunneled catheters.
Placement is usually surgical, often in an outpatient setting.
May be single, double, or quadruple lumen.

Peripherally Inserted Central Catheters (PICCs)

Typically used for 1 week to 6 or 12 months.
Inserted into a vein in the arm (usually cephalic or basilic).
Placed in the lower one-third of the superior vena cava.
Nontunneled.
Can be placed in an outpatient setting by trained personnel.
Redness, swelling, drainage, tenderness or dressing condition should be assessed.
Phlebitis can occur within 7 to 10 days after insertion.
The arm with the PICC should not be used for blood pressure measurements or blood draws.

Implanted Infusion Ports

Long-term use (1 year or more).
Commonly used for chemotherapy.
Placement is surgical, into a chest wall pocket.
The catheter tip is in the superior vena cava.
Accessed by specially trained personnel with a Huber-point needle.
Equipped with a self-sealing silicone septum.
Drugs are injected through the skin into the reservoir then released into the bloodstream.
Regular flushing is essential.

Tunneled Catheters

Insertion involves placing part of the catheter in subcutaneous tissue. The Dacron cuff is placed to create separation between the skin and the vein where the catheter enters.
The subcutaneous tunnel separates the entry point from the vein, reducing the risk of infection.

Nontunneled Catheters

Used only for short-term use (no more than a few months for typical use).
The catheter tip rests in the superior vena cava.
Gauze dressings are changed every 48 hours and transparent dressings every 5-7 days as needed.
May have single, double, or quad lumens.

Nursing Management of CVADs

Inspect the catheter and insertion site.
Assess for pain.
Change dressings according to facility policy.
Review injection procedure in the hospital/facility laboratory setting.
Regular flushing is important.

Removing Central Lines

Performed according to institution policy.
Only trained nurses should remove lines.
Gently withdraw the catheter while the patient performs the Valsalva maneuver.
Ensure the catheter tip remains intact.
