What is a Central Venous Assess Device (CVAD)?

Tube passed through a vein to end up in the vena cava or in the right atrium.

Self-Administration of IV therapy
Sclerosed peripheral veins
Limited peripheral access

Is it implanted or external?
How many ports/lumens does it have?
Is the tip open or valved?
Is the external tunneled or non-tunneled?
Where does the tip end?
Is it designed for dialysis or not?

Basilic Vein
Cephalic Vein
when will it end if using femoral vein

why
not desirable
Why?High incidence of complications
where will these normally end up-
best is-
true-
Superior Vena Cava
Best is at right atrial junction
True CL placement
what do you need to do before using central line
can rn read X-ray
what need before using
All central lines must be confirmed with X-ray before use!
Rn cannot read the xray- but need the xray to confirm its correct before usage
RN Responsibilities include
monitor what
use what
change dressing how often
assess before what
respond
assisting with
who can insert pics
Monitor & Assess CVL, PICC, and implanted ports
Use STERILE technique! (sterile gloves)
Change dressings(q7days), change caps (q7days or after blood draw), and flush per protocols
Access CVL, PICC and implanted ports for medication administration, blood draw, and IV infusions
Respond to any adverse situations related to these devices
Assisting with placing CVL and implanted ports (surgical)
PICC certified nurses can insert PICCs under Ultrsound guided!
Assessment of the CVAD includes:
trace where
assess
monitor
assess what
asses for any
always do what
Trace line(s)-bag to pump to line
Assess site, dressing, caps
Monitor for any s/s infection
Assess patency
Assess for any potential complications
Always look at patient! How do they look?
Central Line Dressing Change
how often
patient lays how-wears what as well
with gloves do what
put on what
cleanse w/
cover w/
might have
Usually changed 5-7days (per agency policy)
Patient should lay on back and turn head away (can wear mask)
With clean gloves, remove old drsg
Put on Sterile gloves
Cleanse with chloraprep for at least 30 seconds
Cover with sterile dressing and biopatch, depending on agency policy
Might have small gauze if recently inserted.
Infusion via Central lines

do what before removing syringe

connect
__lumen
pump
remember
Scrub the hub
Attach 10 ml saline syringe
Unclamp lumen
Aspirate for blood return
Instill saline slowly, approximately 5 ml-Maintain positive pressure!
Clamp catheter before removing syringe
Scrub the hub again
Connect IV fluids, unclamp lumen, set pump.
Remember to trace your line.
Administration of medications via central lines
same as what
except need(x2)
Same procedure
except you always need at least a 10ml syringe and you may need to use the SASH method:
SASH method
saline
administration
saline
heparin
why always use a 10 ml syringe
always use a 10 ml or larger syrnge when apritating- anything smaller may collapse catheter
Managing Ports
brown
red
white
Brown (usually largest) – Use for blood administration
Red – use for blood draw
White – TPN or IV fluids
what to do with a port when withdrawing blood
Stop all infusions when withdrawing blood becayse it may scew results
PICC: Assisting in insertion
put patient in what
place what//turn where
maintain
watch what for what
Patient in Trendelenburg
Place mask on pt and turn pt’s head away from side of venipuncture.
Maintain sterility.
Nurse watches the ecg to make sure pt doesn’t go into lethal rythmm
why put the patient in trendelenerg
(to prevent air embolism and help distend subclavian and jugular veins).
What should you do when a PICC pulls out even a small amount?
do not
notify

Do NOT push a PICC line back in
Notify physician

Supine flat or 10 degree
Hand hygiene, PPE
Remove old dressing
Sterile gloves, sterile dressing kit and suture removal supplies
Hold 4x4 gauze to site-sterile
Deep breath (them)and Valsalva maneuver as catheter is removed
Smooth, continuous motion, immediate pressure at site
Apply sterile occlusive dressing
Inspect tip intactness and length
Remain in supine position for 30 minutes

Surgically placed under skin in SQ pocket
Attached catheter enters superior vena cava
Accessed with special needle, non-cored (Huber) which can remain in place for 7 days
Newer ports are MRI/CT compatible (POWERPORTS)
Used for long-term (Chemotherapy

Air embolism:

monitor for
Potential Complications with CVAD
Trendelenburg position, turned to left(in suspected and confirmed)(prevents air from rising to brain)
Administer 02 via non-rebreather at 15 ml
Call rapid response immediately-put patient in hyperbaric chamber
Monitor for Respiratory Distress, BP, Pulse
air embolism prevention
always have
c and use
no what should ever be in
Always have pt. perform Valsalva’s maneuver;
clamp and use positive pressure
-no air should ever be in anything that you are pushing in catheter
Infection:
prevention:
keep clients
can shower but
Potential Complications with CVAD
Prevention: Wash hands, maintain sterile technique!-use sterile awlays
Keep clients head turned away when accessing or changing dressing
Can shower but need to cover appropraitly
Dysrhythmia:
assess for
if Cath is rubbing-causes
watch
Potential Complications with CVAD
Assess patient for any palpitations/chest pain
If cath is in right place but rubbing against the wall it can cause life threatening dysrhythmias
Watch monitor always
Catheter dislodgement –

Potential Complications with CVAD
stop all infusions,
