Protecting your access: the daily habits that decide how long it lasts

Everything else in dialysis can be rescheduled. Your access cannot be replaced casually — sites are limited, each new one is a procedure, and a fistula that fails takes time and often a temporary catheter to work around. The routine that protects it takes about a minute a day.

Your unit will have shown you the specifics for your access. What follows is the general shape of it, so the daily habit makes sense rather than being a list you half-remember.

If you have a fistula or a graft: check it every day

You are checking that blood is still flowing through it, and that nothing is developing around it. Two things to sense, and a look.

• The thrill — rest your fingertips lightly over the fistula. You should feel a continuous buzzing vibration, not a pulse that taps. A pulse where a buzz used to be is a change worth reporting.
• The bruit — put your ear close, or use a stethoscope if your unit gave you one. You are listening for a low continuous whooshing sound.
• The look — check for new redness, swelling, warmth, discharge, a hard lump, or skin that has become shiny and thin over a bulge.

Do this at the same time each day so a change registers as a change. It is the difference between noticing on Tuesday and noticing at your next session.

The rules for that arm

• No blood pressure cuff on that arm. Tell every nurse, every clinic, every camp — nobody will know unless you say it.
• No blood draws and no cannula on that arm, including in an emergency department. Say it early and say it again.
• No sleeping on it, and nothing tight around it: no watch, no bangles above the site, no tight sleeves, no bag strap hooked over that arm.
• No heavy lifting with it, though normal use is fine and gentle exercise is often encouraged. Ask your unit what they want for yours.
• Keep the skin clean, and wash the area before your session.
• After needles come out, hold firm pressure as your unit showed you — steady and direct, and do not keep lifting the gauze to look.

If you have a permcath or a tunnelled catheter

The trade-off is different: no needles, but a permanent opening, which means infection is the main risk and the rules are stricter.

• Keep the dressing dry and intact. No baths, no swimming, no submerging. Showering only if your unit has told you how, with the covering they specified.
• Do not touch the caps or clamps, and do not let anyone who is not trained for it open the line. It is not a port for ordinary use.
• Only the unit changes the dressing, unless you have been specifically trained. If it becomes wet, loose, or dirty, contact them rather than fixing it yourself.
• Look at the exit site daily for redness, swelling, discharge, or tenderness.
• Keep the line secured so it cannot be tugged — by clothing, by a seatbelt, in a crowd, or in your sleep.

Make the information reachable by someone else

The people most likely to need your access details are strangers treating you in an emergency, and you may not be in a position to explain. A note in your wallet and a contact your family can find beats a memory under pressure. If you travel, this matters more, not less.
