question
4 Types of CVAD
answer
1. Nontunneled: Central venous Catheters (CVC) Ex. Triple Lumen 2. Tunneled Catheters: Ex. Hickman, Broviac 3. Peripherally Inserted: Central Catheters PICCs 4. Implanted Port: Port-A-Cath
question
Nontunneled Central Venous Catheter site? where inserted? conformation? securement? time frame?
answer
Site: subclavian, jugular or femoral vein Inserted at bedside Placement confirmed with X-ray Held in place with sutures or securement device Short term therapy
question
Nontunneled CVC lumens? flush? risk?
answer
1 to 4 lumens Flush with normal saline May flush with low concentration heparin (100 units/ml) Femoral access possible but not first choice, - increase risk of infection Risk: pneumothorax
question
Tunneled Central Venous Catheter site? insertion? securement? time frame?
Tunneled Central Venous Catheter site? insertion? securement? time frame?
answer
Site: chest, subclavian Inserted in OR or IR Held in place Dacron cuff Long term use tunneled subcutaneously to exit site on chest
question
Tunneled Catheter types? how works?
answer
Examples: Groshong, Hickman Has a valve that reduces risk of blood reflux and clotting >> no need for Heparin Pressure opens and closes valve
question
Peripherally Inserted Central Catheter
Peripherally Inserted Central Catheter
answer
length 20-24 inches No venipunctures or blood pressures in arm Assess for catheter migration by measuring external catheter length from hub to insertion site Held in place with sutures or securement device Power PICC: larger lumen, withstand more pressure *NEVER use a syringe smaller than 10mL * A mid-line catheter is shorter (8-10 inches), not the same Midline tip under axillary area, longer than a peripheral but shorter than CVC, not central venous access Caution: Looks same as PICC but not caution when infusing meds or TPN
question
PICC - Double Lumen
PICC - Double Lumen
answer
Note clamps and stabilization, 10 ml syringe
question
Implanted Subcutaneous Port site and type
answer
Long term use (oncology patients) Sites: chest, abdomen, inner arm "hidden" under the skin, when not accessed nothing external No dressing change once healed, Tunneled catheter Single or double port Access with a 90 degree non-coring safety needle
question
Port-A-Cath
answer
Surgically implanted port subcutaneously, accessed with Huber needle; flushed with heparin Usually Needle changed every 7 days
question
Needle free cap/hub connector
answer
All CVC need an adapter or "cap" to provide a closed system to prevent air from going in and blood flowing out.
question
Nursing Management of CVADS what needs to be done before using it?
answer
Assist MD/HCP with insertion Confirm placement before using catheter!!!!!! Assessment and maintenance is RN responsibility Maintain patency Maintain sterile technique Apply dressing and cap changes per protocol Administer IV fluids & medications Prevent complications - *infection* * Always per hospital protocol*
question
assessment of catheters
answer
Type of catheter Date inserted, date of last dressing and cap change Skin integrity insertion site & surrounding area- redness, edema, pain, drainage, leaking Assess patency of catheter Assess for signs or complications Assess patient's knowledge ; learning needs
question
Flushing the catheter reason and technique
answer
To maintain patency Wash hands apply non-sterile gloves Flush with 10mls of sterile normal saline (20 mls following blood draw) Use 10 ml pre-filled saline syringe expel all air bubbles Scrub hub - twist alcohol wipe for 15 -30 seconds ; allow to dry Push-Pause technique Flush ALL lumens not being used for infusions Clamp unused ports if indicated per protocol Syringe size - smaller creates increased PSI, "Minimize contamination risk by scrubbing the access port with an appropriate antiseptic (chlorhexidine, povidone iodine, an iodophor, or 70% alcohol)" CDC Guidelines
question
Which lumens get flushed on catheters
answer
Flush ALL lumens not being used for infusions Clamp unused ports if indicated per protocol
question
Push pause technique and why?how to end?
answer
Creates positive pressure ; turbulence to keep catheter patent Push 1 -2 mls, pause, push 1-2 mls pause, continue until all 10 ml instilled but END with positive pressure Alternate pushing ; pausing on syringe plunger apply a steady gentle pressure
question
Flushing catheter procedure?
answer
Don non-sterile gloves "scrub hub" with alcohol or chloraprep Allow to dry Expel air bubbles from 10 mL pre-filled saline syringe Attach saline flush to catheter hub, twist on Inject saline using push-pause technique (positive pressure) End with pressure on plunger while removing syringe Apply disinfectant cap IF Heparin flush indicated per protocol: Scrub hub again for 15 seconds Attach heparin filled syringe (100u or 10u per mL) Instill correct amount of Heparin per hospital protocol Apply disinfectant cap
question
Administering Medication S.A.S.H Method
answer
"Scrub hub" - antiseptic solution (15 - 20 seconds) each ; every time you access S aline - sterile normal saline 10 ml syringe A dminister - IV medication - using 6 rights ; 3 checks! S aline - flush with 10 ml saline after IV medication H eparin - only if indicated **per protocol** **heparin may be used as last flush to prevent thrombus forming, low concentration 100u/mL or 10u/mL
question
why do we use a 10 mL syringe with flushing a catheter?
answer
Use a 10 ml syringe because smaller size syringes create increased pressure on catheter lumen
question
Administering a med via CVAD part 1
answer
Perform the 3 checks ; 5 rights of medication gloves Scrub hub ; allow to dry Attach prefilled 10 mL saline syringe *Pull back plunger slightly to aspirate small amount blood Inject saline using push-pause and remove syringe
question
administering a med via CVAD part 2
answer
Scrub hub again Connect IV tubing with medication ; set IV pump to infuse at correct rate (ml/hr) When infusion complete - Disconnect IV tubing, put a sterile cap on end of IV tubing scrub hub and flush (push-pause) with 10 mLs of saline If using Heparin ; scrub hub again and administer Heparin as prescribed per hospital protocol Apply disinfectant cap Clamp CVC if indicated
question
CVAD dressing change
answer
Gauze dressing for first 24 hours then..... Transparent dressing Wash site with antiseptic solution (chlorhexidine) for 30 seconds Chloraprep applicator - break ampule release antiseptic into sponge allow time to air dry Apply stabilization device label dressing Usually every 7 days ; PRN Measure catheter length
