Vascular Access Devices
Valved Catheters
• Closed-ended valved catheter: Groshong®
‒ Slit valve near distal tip of catheter
‒ Three way pressure sensitive valve
‒ No heparin needed
‒ No clamp
Vascular Access Devices
Valved Catheters
• Open-ended valved catheter: PAS-V®, SOLO®
‒ Pressure sensitive valve is in hub
‒ No heparin needed
‒ No clamp
Vascular Access Devices
Non-Valved Catheters
• Distal tip open
• No pressure sensitive valve
• Requires heparin to prevent backflow of blood into catheter,
causing clot formation
Non-valved catheters
usually have clamps and
must be clamped at all
times when not in use!

Vascular Access Devices
Power Injectable Catheters
• Power injectable catheters are designed to withstand the high
pressures associated with procedures requiring the use of
contrast media.
• Power rated catheters are manufactured using stronger grade
plastics that allow for infusion of solutions at rapid rates of up to
5 mL/second and compatible with pressures of up to 300 PSIs
required during contrast enhanced CTs.
Vascular Access Devices
Power Injectable Catheters (cont)
• PICCs, implanted ports, tunneled and non-tunneled catheters
may be rated for power injection
• External catheters rated for power injection may have a purple
hub, purple catheter and/or purple clamps to help identify them
as power injectable. Caution: not all power rated catheters
are purple. Other brands have the power rated clearly labeled
on the hub or other external part of the catheter.
Vascular Access Devices
Power Injectable Catheters
• Power rated implanted ports may have raised tabs that can be
palpated on the septum to identify them as power rated ports
• In the LTC setting, catheters that are rated for power injections are
maintained and utilized the same as non-power rated catheters
• Regardless of power rating, follow prescribed flushing/locking
protocols for catheters according to catheter classification
• Power injectable catheters may be valved or non-valved. Follow
prescribed flush based on catheter type.
1/22/2016

Vascular Access Devices
Power Injectable Catheters • Power injectable catheters may be single or multi-lumen. The lumens
able to be used for power injections will be marked.
• Infusion of solutions or medications in power rated catheters shall not
exceed manufacturer’s recommendations for the medications or
solution being infused. For example: Vancomycin 1 Gram in 250 mL of
normal saline infused through a power injectable catheter would still be
infused over 90 minutes.
With all vascular access devices, information from the referring institution
is the best way to identify the type and brand of the catheter.

Vascular Access Devices
Peripherally Inserted Central Catheter (PICC)
Where is the tip supposed to be?
• According to national guidelines, the tip of a PICC must terminate in
the superior vena cava, not in the right atrium, subclavian, or
innominate (brachiocephalic) vein
• If not in the SVC, the tip is malpositioned and should be adjusted.
Adjustments are done under fluoroscopy or by a PICC qualified nurse.
‒ Tips in the subclavian and innominate veins have a higher risk of
thrombophlebitis development
‒ Tips in the atrium can lead to arrhythmias

Implanted Venous Port
An implanted venous port is a catheter that is surgically placed into a blood
vessel and is attached to a reservoir. The tip terminates in the superior vena
cava (SVC).
• The reservoir is placed under the skin and has a self-sealing septum, or
diaphragm.
• The port is accessed using a percutaneous needle directly through the skin
and septum.
• Venous ports may be implanted in the chest or upper extremity. Once placed,
a port is completely covered by skin with no exposed parts.
Vascular Access Devices
Implanted Venous Port
• Stainless steel, titanium, or plastic reservoir with silicone septum connected to silastic catheter
• Self sealing septum allows multiple punctures
• Available in single or dual ports. A dual lumen port has two separate septums, reservoirs, and catheters.
• Most ports are placed in the chest and sutured into a subcutaneous pocket created by the surgeon located superficially above the breast tissue, although smaller ports may be implanted into the arm (e.g., P.A.S. Port® and X-Port™). If a patient has an implanted port in their arm, blood pressure cuffs and tourniquets should be avoided on the affected arm.

Vascular Access Devices
Implanted Venous Port
Port Specific Complications
• Port malposition – May be seen after there has been trauma to the
port body. One of the major complications that is seen when this
occurs is the port flipping over inside its subcutaneous pocket. The
nurse will not be able to access the port as the needle will be hitting the
bottom (back) of the port reservoir. Should this occur, surgical
intervention is needed.
If the non-coring needle becomes partially removed from the port body during active therapy, do NOT attempt to push the needle back into the septum of the
port. Instead, de-access and re-access per facility policy.
Vascular Access Devices
Implanted Venous Port
Port Specific Complications
• Port erosion –May occur as a result of a misplaced non-coring
needle; improper needle length selection, or as a result from a
malnourished patient in negative nitrogen balance.
Vascular Access Devices
Implanted Venous Port
Port Specific Complications
• Extravasation – A partially dislodged needle is the most common
reason for extravasation. Always assess the needle placement and
dressing integrity, especially when vesicants are infusing. In addition,
verify the presence of a brisk blood return. If swelling is noted during
an infusion, or patient has pain over port during an infusion, promptly
stop the medication, assess the patient and follow physician/LIP order
for extravasation, as needed.
1/22/2016
23
Vascular Access Devices
Implanted Venous Port
Port Specific Complications
• Twiddler’s syndrome – This is a rare complication that can
occur due to the resident’s consistent manipulation of the port’s
body. This manipulation loosens, or breaks, the sutures which
were holding the implanted port’s body into the subcutaneous
pocket.
Vascular Access Devices
Implanted Venous Port
Assessments to be performed before accessing the port:
• Verify orders: for accessing/de-accessing; flushing
solutions/amounts/frequency; blood draws
• Ensure that the skin over the port is not inflamed, or showing s/s
of infection. Do not access if symptoms present, and follow up
with physician/LIP.
• Gently assess the mobility of the port
• Assess the depth of the port body to aid in determining the
needle length needed

Hemodialysis/Apheresis Catheters
Hemodialysis
Hemodialysis is a method for removing waste products such
as potassium and urea as well as free water from the blood
when kidney function is inadequate (e.g., renal failure).
Vascular Access Devices
Hemodialysis/Apheresis Catheters
Apheresis
Apheresis is the process of temporarily removing blood from the
body and separating it into its components.
• Blood is made up red and white blood cells, platelets, and plasma
• Some diseases are caused by excessive numbers of these cells and
by abnormalities of the proteins and other substances dissolved in the
plasma
• During the apheresis process the unwanted component(s) can be
discarded before returning the other components to the body

Hemodialysis/Apheresis Catheters
• Hemodialysis/apheresis catheters are often large-bore, dual
lumen tunneled catheters.
• Short term catheters are often made of polyurethane, and long
term catheters of silicone.
• Apheresis may also be accomplished via large bore short
peripheral catheters.
Vascular Access Devices
Hemodialysis/Apheresis Catheters
• Hemodialysis/apheresis catheters must be clearly marked with
tape, or a printed label:
“Hemodialysis (or Apheresis) Catheter –
Do Not Access Without Permission”

Care and Maintenance
• The facility nurse’s role in the care of the catheter is:
− Ensuring clamps are closed, if present
− Monitoring the integrity of the patient’s dressing and needleless connectors. Dressings are routinely changed during the patient’s dialysis treatments. If the dressing becomes wet, loose, or soiled, and the dialysis nurse is not available, the licensed nurse may change the dressing. A sterile dressing change must be done as soon as possible. Follow dialysis center’s instructions for emergency care and maintenance.
− Notifying the patient’s hemodialysis nurse/nephrologist/LIP if complications occur

Care and Maintenance
• Because of the large diameter necessary to accommodate the flow rates for hemodialysis and apheresis, flushing/locking protocols are different from other central vascular access devices.
− Hemodialysis/apheresis catheters are usually locked with higher heparin concentrations to avoid the development of intraluminal thrombosis.
− The volume used is usually equal to the internal volume of each specific lumen.
− This high concentration of heparin is withdrawn prior to flushing with next use to prevent heparin bolus.
− Specific orders must be obtained if the nephrologist/dialysis center wants the catheter flushed/locked and/or dressing changed in the post-acute care setting.

Assessment
• Any bleeding or drainage at catheter site must be reported to the
nephrologist, hematologist, oncologist or dialysis center immediately
• In the event of catheter fracture or breakage:
− Immediately clamp the catheter as close to the chest wall as possible
− Position patient in bed on left side in Trendelenburg (head down)
− Notify appropriate physician/LIP
− Arrange for immediate transport to acute care facility for catheter
assessment/repair
A smooth edged clamp must remain with the patient at all times
