An Implantable Vascular Access Device

This handout will explain what a “port” is and how to care for it once you are home. If you have
any questions, please ask. Our staff is here to help you.

What is a port?

A port is a small rigid disc about the size of a half dollar. The center is raised and designed to
receive a needle (see drawing). You can feel the raised center under the skin.

The septum is made of self-sealing silicone. This
means it can be punctured hundreds of times with a
special needle. There is a plate under the septum,
so the needle cannot go all the way through the

Attached to the base of the port is a narrow flexible
tube. This is called a catheter. It is inserted into a
vein where the medicine is to go.

What is the purpose of the port?

The port may be used to draw blood for tests and to inject medicines into the bloodstream. It
may also be used for infusions when large amounts of fluids are needed, such as blood
transfusions, IV antibiotics, IV chemotherapy, or IV nutrition. It is not used for CT scans.

How is the port placed?

Your port will be inserted during a brief operation. The port is most often placed under the skin
just below the left or right collarbone. In some cases it may be placed in the abdomen, between
the breasts, under the arm on the side of the chest, or in the forearm. The surgeon will create a
small pocket for the port and then insert the catheter into a vein. A few stitches will be needed to
complete the operation. The incision will be closed with absorbable stitches and a special tape
that will dry and fall off when healed. PAS ports are placed in the arm and are a little smaller.


Adults: The port may be placed in Outpatient Surgery or Interventional Radiology. In
most cases the procedure is done under local anesthesia using numbing medicine
at the site. There is a chance that you may also be given medicine to help you
relax. This medicine can make you drowsy. Please arrange to have someone
drive you home. You should not drive or make important business or personal
decisions until the next day.

During your recovery, a nurse will review your home care with you.

Children: Most children will receive general anesthesia. This is done in the operating room.
Most children will not need to stay overnight if coming for port placement only.
The port can be used the same day that it is placed. Your doctor and nurses can
answer any questions you may have.

How Do I Care For My Infusaport ?

When to access and flush your port

Flush your port once a month with 20 mL of normal saline followed by 5 mL of monthly heparin
(100 u/ml) to prevent clots from forming.

If you receive infusions at home

1. Your port must be flushed after each use (at least once per day).
2. Use 10 mL normal saline followed by 5 mL of the daily heparin (10 u/ml).
3. If you plan to remove the needle or not flush it for more than 24 hours, flush the port with
10 mL of normal saline followed by the 5 mL of the monthly heparin (100 u/ml).
4. Change your needle at least once per week.
5. Change the needleless connector once or twice per week or if it is contaminated with
6. Cover the port dressing while you shower so it does not get wet

Note: Two concentrations of heparin are used.

Daily heparin is used after medicine infusions and is 10u/ml

Monthly heparin is used before pulling the needle and is 100u/ml

Flushing the port may be done by your UW clinic, local health care provider, or yourself. If your
doctor or nurse flushes the port, please give him or her a copy of the flushing protocol.

How to access and flush your port

Most patients have their ports accessed by a health care provider. Parents of small children are
often taught how to access their child’s port. An accessed port is a port that has a needle in it.


ξ ChloraPrep
ξ Sterile 4 x 4 gauze
ξ Sterile gloves
ξ Sterile non-coring Huber needle (20G 3/4 inch-common size)
ξ Pre-drawn normal saline and heparin flushes
ξ One tube of EMLA or LMX cream (optional)
ξ needleless connector
ξ 2x2 Alcohol swabs

Other supplies (if needle is to be left in place)

ξ Steri-strips or sterile tape
ξ One transparent adhesive dressing
ξ Sterile 2x2 gauze (optional)
ξ Biopatch (optional)

If EMLA will be used, apply a large dollop to the port site and cover with a transparent
adhesive dressing. Wait 60 minutes. If LMX® will be used, rub a small amount of cream into
skin for about 30 seconds. Add a “bubble” of LMX®. on top of this area of skin then apply a
transparent adhesive dressing for 20‐30 minutes to numb the skin.

1. Wash your hands with antibacterial soap or alcohol hand gel for 30 seconds.

2. Open the sterile glove package to set up the sterile field.

3. Peel open the normal saline and heparin flush packages. Lay them down next to the
sterile field. Open 2 large sterile 4 x 4 gauze squares and drop onto the sterile field.
Open the ChloraPrep and drop onto the sterile field.

4. Open the Huber needle and needleless connector and drop them onto the sterile field.
Be careful not to touch any part of the Huber needle. Always access your
Infusaport® with a Huber needle. Using other needles may damage your port and
cause it to leak.

5. Put on your sterile gloves. Twist the needleless connector onto the Huber needle
extension set.


6. Pinch the wings on the applicator to release the
ChloraPrep into the sponge pad. Do not touch the
skin with your fingers. Gently press the sponge
against the skin over the port until you see the
liquid on your skin. Clean the port site and 2-3
inches of skin around the site for one minute using
back and forth friction.

7. Allow to air dry. Do not blot, wave at, or blow dry
the area. While it is drying, do not allow your
clothing to come in contact with the place you just
cleaned, or you will have to use another applicator and start over.

8. Be sure to keep all supplies sterile. The outsides of the saline and heparin flush
syringes are clean, not sterile.

9. Pick up the saline syringe with a sterile 4 x 4 and twist it on the end of the needleless
connector. Push the saline through until you see it drip out the other end. Lay the set
down on your sterile field. If a family member is present, they can help you push the
saline through. Keep the syringe attached to the tubing.

10. Maintain the sterility of the needle and tubing. By holding the colored wings and
syringe in your dominant hand, remove the cap on the needle with the other hand. Feel
for the port while your dominant hand guides the needle into the septum or port at a 90 θ
angle. Press firmly until the needle touches the back wall of the port. Pick up a
transparent dressing and place it over the top of the port to secure the needle in place. If
you are leaving the needle in for IV therapy, put a sterile piece of tape over the wings of
the needle so it is more secure. Then, cover it with a transparent dressing.

If you are just doing your monthly flush, skip the dressing and go right to step 13.

11. Slowly pull back the plunger until you see blood in the tubing.

12. Make sure you check for air in the flushes and remove all air before using.

13. Push down on the plunger and flush the port with 10 mL of normal saline. Clamp,
attach, and flush an additional 10 mL of normal saline. Small children with ports only
need to use 10 mL of normal saline.

14. Clamp and attach 5 mL syringe of heparinized saline. Unclamp, flush, and clamp.
Leave the syringe attached if you remove the needle.
ξ 100 u/mL heparin for monthly flush or flushes over 24 hours
ξ 10 u/mL heparin for daily flush


15. To remove the needle: While securing the port with two fingers of one hand, pull out
the needle and dispose of it in the Sharps Box. Safety Huber needles are often used in
the hospital, but are not needed at home if you are doing your own port access. If you
need instructions on safety Huber needles, contact your nurse.

16. Cover the port dressing while in the shower. Change the dressing any time it becomes
wet or loose. A Biopatch antiseptic foam patch is for ports. If the needle is to remain
in for a week and if there is room for the Biopatch , it may be placed around the needle,
foam-side down on the skin, blue shiny-side up. If the Biopatch is used under the
dressing, the dressing can stay on all week, as long as it stays dry and secure. Sterile
2x2 gauze is another option to “pad” the wings of the Huber needle.


When your port is not accessed, you may safely swim, exercise, and engage in activity as usual.

1. Avoid any direct blow to port site.

2. Avoid heavy contact sports (i.e., football, hockey, etc.). If a heavy contact sport is
desired, consult your doctor or nurse.

3. You may try less aggressive sports (i.e., volleyball, basketball, etc.).

4. Do not leave the port site exposed during contact sports.

5. Take precautions to protect the port site (i.e., padding, wearing a heavy shirt, etc.).

Be aware of the signs of infection listed below. Call your doctor if any of these symptoms occur.

ξ Site becomes red and hot or tender to the touch.
ξ Temperature above 100 θF.
ξ Excess swelling or bleeding of the skin.
ξ Drainage from the site.
ξ Pain or discomfort at the site.
ξ Difficulty flushing the port.

Your doctor will watch the site for infection and draw blood cultures through the port for testing.

Most of the time, ports work well for lab draws and IVs. Once in a while, ports stop working.
When this happens, your nurse will very likely be able to get it working again by placing a small
enzyme in the port needle.
