Caring for a central line at home, and knowing when it is infected | CION Cancer Clinics
Central line care at home comes down to three things: keep the line clean, dry and covered, look at it every day, and act the same day on any sign of infection. A fever of 38°C or higher, or shivering after a flush, means going to the emergency department now. This page explains the daily checks, safe handling, everyday life with a line, and what only your team can decide. At CION Cancer Clinics, our haematology team supports patients and families through treatment, cost questions and life at home.

The short answer
What does caring for a central line at home actually involve?
Caring for a central line at home means keeping it clean, dry and covered, looking at it every day, and acting the same day if you see signs of infection. Flushing and dressing changes are usually done by a trained nurse, either at the day-care unit or at home, on a schedule your team gives you.
Why the line needs this much attention
A central line is a thin, soft tube that sits in a large vein near the heart. It lets the team give chemotherapy, blood and platelets, and take blood samples without a new needle each time. The same open path that makes it useful also lets germs from the skin travel straight into the blood. During blood cancer treatment your white cells, the ones that fight infection, are often very low. A small infection that a healthy person would shake off can become serious within hours.
Who does what at home
You, or the family member caring for you, are the daily watcher. You keep the dressing intact, keep the line clamped and secured, and notice changes early. The nurse does the flushing and the sterile dressing change unless your team has trained you to do it and watched you do it correctly.
Never flush, unclamp or repair the line yourself unless your own team has trained you and asked you to.
!
Fever or shivering with a central line cannot wait
If your temperature is 38 degrees Celsius or higher, or you start shivering or shaking, especially soon after the line has been flushed, go to the nearest emergency department now or call 108. Say that you have a central line and are on blood cancer treatment. Do not take paracetamol first and wait to see if it settles. It hides the fever without treating the infection underneath.
Not sure whether this applies to you?
Ask an oncologistEvery day
What should you check on the line each day?
A two-minute look in good light, once in the morning and once at night, catches most problems while they are still small.
The skin where the line comes out
Look at the exit site through the clear dressing. A little dryness is common. Spreading redness, warmth, swelling or pain is not.
Call the team the same day for
- Redness that is growing
- Pus or cloudy fluid
- Tenderness along the line
The dressing
It should be dry, sealed at the edges and not lifting. If it is wet, loose or dirty, cover it with a clean dressing and ask for a proper change the same day. Do not leave it open to the air.
The line and the clamps
Check the clamps are closed and the caps are firmly on. Look for any crack, leak or kink. Keep the line taped or looped so it cannot be pulled by clothing or a child.
If the line cracks, clamp it above the damage and call the team at once.Your arm, neck and chest
New swelling of the arm, neck or face on the side of the line, or visible veins across the chest, can mean a clot has formed around the line. This needs checking the same day.
Before anyone touches it
How do you handle the line safely at home?
Clean hands first, every time
Wash your hands with soap and running water for a slow count, then dry them on a clean towel or paper. Anyone who touches the line or dressing does the same, including the nurse.
Prepare a clean surface
If a nurse is visiting, clear a table, wipe it down and keep pets and children away. Fans and open windows blow dust, so switch them off for the few minutes the line is open.
Keep the caps and ends covered
Never let the open end of the line touch skin, clothing or bedding. If a cap falls off, do not put it back. Clamp the line, cover the end with clean gauze and call the team.
Write it down
Keep a small notebook with the dates of each flush and dressing change, and anything you noticed. It helps the team see a pattern quickly.
Side by side
What is usually fine, and what needs a call?
Usually fine
Call the team the same day
Slight itching under the dressing
Redness, pus or pain at the exit site
A small dry crust where the line leaves the skin
Fluid leaking from the line or the site
Feeling the line move a little under the skin
The visible part of the line suddenly looks longer
Mild soreness in the first days after insertion
Swelling of the arm, neck or face on that side
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
Living with the line
Can you bathe, sleep and move around normally?
Yes, with some care. Most people carry on with ordinary daily life with a central line. The rules are about keeping it dry and keeping it from being pulled.
Bathing
Take a bucket bath or a short shower rather than sitting in water. Cover the dressing with a waterproof cover or cling film sealed with tape, and keep the shower head pointed away from it. Swimming is not safe while the line is in. If the dressing gets wet, it needs changing the same day.
Sleeping, clothing and children
Loose cotton tops with buttons at the front make the line easier to reach and less likely to catch. Sleep on the other side if you can. Small children love to pull at tubes, so keep the line tucked and taped and hold a child on the opposite side.
Work, travel and home in a district town
Light work is often possible. Avoid heavy lifting and hard exercise with the arm on the line side. If you live far from the treating centre, ask before discharge where the nearest place is that can handle a line problem, and keep that number with you.
Commonly believed
What do families often get wrong about central lines?
"If the site looks clean, the line cannot be infected."
An infection can sit inside the line with no redness at all on the skin. Fever or shivering, especially just after a flush, can be the only sign. That is why a fever is treated as urgent even when the dressing looks perfect.
"Putting antiseptic powder or turmeric on the site will protect it."
Anything placed under the dressing that the team has not given you can irritate the skin and hold germs. Use only what the nurse uses, and let the team decide on the cleaning solution.
"We should wait until the next visit to mention it."
A small problem at the exit site is much easier to treat early. Calling the team the same day is not bothering them. It is exactly what they have asked you to do.
"An infected line always has to come out."
Not always. Some line infections are treated with medicine given through the line itself. Whether it is removed depends on the germ, how unwell you are and your treatment plan, and only your team can decide that.
Questions we are asked
Common questions about central line care at home
How do I know if my central line is infected?
Watch for fever, shivering or feeling suddenly unwell, particularly soon after a flush. At the exit site, look for spreading redness, warmth, swelling, pain or pus. Any of these needs a call to your team the same day, and fever or shivering means going to the emergency department now. This page cannot tell you whether a line is infected. Only an examination and blood tests can.
How often does the line need flushing and a new dressing?
It depends on the type of line and the dressing used, so your team sets the schedule and writes it down for you. Some lines are flushed more often than others. Ask for the schedule in writing before you go home, and ask who to call if a visit is missed or a dressing comes loose between visits.
Can I do the flushing myself?
Only if your team has trained you, watched you do it correctly and asked you to. Flushing uses sterile equipment and an exact technique, and a mistake can let air or germs into the line. For most families in and around Hyderabad, a nurse at the day-care unit or a home-care nurse does it.
What do I do if the dressing gets wet or comes off?
Wash your hands, cover the site with a clean dry dressing or gauze, and call your team to arrange a proper change the same day. Do not leave the site open, and do not reuse the old dressing. If the line has moved or looks longer than before, say so when you call.
The line is leaking or cracked. What now?
Close the clamp between the crack and your body, or fold and tape the line above the damage if there is no clamp there. Cover it with clean gauze and call your team straight away. If you feel breathless, have chest pain or start bleeding, go to the emergency department or call 108.
Is it safe to have visitors and pets at home?
Visitors who are well are usually fine, but ask anyone with a cough, cold or fever to stay away until they recover. Keep pets off the bed and away from the line, and wash your hands after touching them. Your team may give stricter advice while your white cell count is very low.
Who is the line not suitable for?
A line at home asks a lot of the household. It may not suit someone living alone with no one to check it, or a home far from any hospital that can manage a line problem. If that is your situation, tell your team before discharge. They can plan more frequent day-care visits or a different kind of line.
Does Aarogyasri or insurance cover line care?
Line care is often covered when it is part of an approved blood cancer treatment plan, but the rules differ between Aarogyasri, PM-JAY, CGHS, ECHS, EHS and each insurer, and they change. Call the helpline with your card or policy details and we will help you check what applies to you before you arrange home visits.
