Accessing a port: how much it hurts and what helps

Call 911 if you become suddenly and severely unwell — for example if you cannot catch your breath, feel faint, or become confused — while your port site is red, swollen or draining. A port sits in a line that runs directly to a large vein near the heart, so an infection there is not a minor skin problem and sudden severe illness must be treated as an emergency.

Call your care team the same day if you notice any of the warning signs MedlinePlus lists for a port: the port moving or shifting out of position; redness or red streaks at the site; swelling or warmth; yellow or green drainage; pain or discomfort; a fever above 100.4°F; or being unable to access the port with a needle. Do not wait for your next scheduled appointment to mention any of these.

One exception to the same-day rule: if your port is being used for chemotherapy, a fever is not a phone call. Chemotherapy drops the white cells that fight infection, and CDC treats a fever during chemotherapy as a medical emergency. Go to an emergency department and tell them you have a port. Readers whose port is used for something else — antibiotics, dialysis, feeding — can follow the same-day advice above.

An implanted port is a small device placed under the skin, usually in the chest. MedlinePlus describes three parts: a pouch made of hard metal or plastic, a silicone top that a needle can be pushed through, and a catheter — a tube — that delivers medication into, or draws blood from, a large vein leading to the heart.

Ports are used when treatment is going to run for a while. MedlinePlus lists the situations: extended antibiotic therapy, nutritional support, kidney dialysis and cancer medicines.

The needle does not go into a vein in your arm. It goes into a device just beneath your skin.

To use the port, a health care provider inserts a specialised needle through the skin and through the silicone surface into the portal reservoir underneath. Afterwards, a sterile dressing is applied to prevent infection.

That is the whole procedure. It is quick, and it happens in the treatment chair.

The single most useful fact here comes straight from MedlinePlus: a numbing cream can be used on your skin to decrease the pain of the needle stick.

Some practical notes that follow from that:

• Creams need time to work. Applying one in the waiting room is usually too late — ask your nurse how far ahead to put it on.
• Ask before the appointment where you get it and how to use it. Many people go months without realising it was an option.
• Tell the person accessing you if the site is sore from last time. They may be able to angle differently.
• If access is repeatedly difficult or painful, raise it as a problem rather than a personality trait. Something may be adjustable.

None of this makes the needle disappear. It can make it a small annoyance instead of the part of the day you dread.

When it is not being used, MedlinePlus notes the port remains hidden under the skin with no external protrusion — nothing to catch on clothing, nothing hanging out.

Routine maintenance includes monthly flushing with a special solution to prevent blood clots. That appointment is easy to let slide when you are exhausted; it is worth protecting in the diary.

MedlinePlus also says patients may bathe or swim once healed, though contact sports require provider approval. Ask your own team about the timing in your case, since it depends on how your site has healed.

The escalation list at the top of this page is much easier to act on if you know what your port area normally looks like. Take a look at it when things are calm. Note the usual colour, the usual shape, whether there is any tenderness.

Then, if something changes, you will not be trying to decide from scratch whether it is new. You will know — and knowing is what lets you make the call early rather than talking yourself out of it.
