Central Venous Access Devices- UNIT 1 EXAM Flashcards
What is a CVAD?
Intravenous catheter or infusion port
A CVAD is designed to administer what trough a central vein??
- Medications
- Nutrients
- IV Fluids
- Blood products and other viscous fluids
A CVAD contains one 1___ and multiple __2/__3__/__4_
- Catheter
- Lumens
- Gauges
- Exits
Distal Lumens are primarily used for? (may need to tweak after lecture
- Blood draw
- Blood infusion
- Meds
- CVP
Proximal lumens are primarily used for? (may need to reword after lecture)
- Iv fluids
- Meds
- Blood draw
Inserted into large veins in central circulation with catheter tip ending in ______. _____ confirmation.
- Superior Vena Cava
- Xray confirmation.
What are the indications for CVAD
- Peripheral access not available or contraindicated
- For patients that need moderate to long term use)***
- Need for multiple intravenous access
- Hemodialysis
- Total parenteral nutrition (TPN)
- Chemotherapy
- Multiple blood transfusions/blood draws
- Long term antibiotic/iv medications or solutions
- Central venous pressure monitoring
When preparing the patient for a central line what should you tell your patient.
- Purpose- What will be administered (meds, IV, fluids, etc)
- Estimated length of time. (most often the CVAD will be removed before patient leaves but sometimes it will go home with the patient)
What are the CVAD Insertion: Pre and Post Protocols?
1.Dr’s order & Signed consent
2. Support for patient/family- what to expect in the room,etc
- Surgical asepsis **
3. Pre and post vital signs/assessments
4. Pt in Trendelenburg position
5. Standby assist for physician/PICC team
6. X-ray confirmation
7. Documentation by both parties
What should we know about Port-A cath, Infusaports?
- Surgically implanted line below the skin-tunneled
- External, tunneled through jugular, subclavian, or cephalic/basilic vein
- Expensive
- Long term months to years
- Silicone septum, surrounded by titanium, stainless steel, or plastic
- Single or dual ports
- Chemotherapy
- Huber needle to access
- Less restrictive
What are 3 types of CVADS?
- Non tunneled
- Tunneled
- Port-A-Cath
What should we know about non-tunneled CVADs?
- inserted directly into subclavian (most common), jugular, femoral or peripheral vein.
-(peripherally inserted central catheter = PICC line) - Secured by sutures outside the insertion site to the skin
- Acute, moderate term, = 6weeks
- High infection rate than tunneled
- Nurse can discontinue
Why are non-tunneled CVAD at high risk of infection
More open to air
What are some complications of CVAD’s
1.Infection (CLABSI)
2. Pneumothorax
3. Air embolism
4. Occlusion
5. Thrombosis
6. Catheter Rupture
7. Catheter Migration
What should we know about Peripheral Inserted Central Catheter (PICC)?
Peripheral vein
1. Basilic or cephalic vein, IF peripheral vein can be accessed
2. PICC team or IR insertion
3. No phlebotomy or blood pressures in affected arm
4. Tend to clot easier
What should we know about Tunneled CVAD’s
- Surgically tunneled beneath skin
- Unique due to Dacron cuff on the catheter
-Cuff is sutured in place (SQ tissue) initially then scar tissue secures itself around the cuff- Dacron cuff helps secure, prevent infection
- Common sites- Subclavian vein, IJ,
- Can also be placed in a femoral vein
- Chronic, long term, >6weeks
- Multiple ports
- Nurse cannot discontinue” Must be surgically removed because of the Dacron cuff
When does a nurse assess?
- Dressing change (intact and within time from),
2.med change (checking site),
3.IV fluids,
4.PRN
What are the signs and symptoms of an infection (CLABSI) in a CVAD?
- Redness
- Drainage
- Swelling
- Discomfort at insertion site
- Fever
- Chills
- Tachycardia
- Increased WBC
