Would IV fluids help someone who is dying?

Sometimes IV fluids help in palliative care, but they do not usually help when a person is actively dying and the body is shutting down.

Sometimes IV fluids help in palliative care, but they do not usually help when a person is actively dying and the body is shutting down. In the last days of life, extra fluid may not make the person stronger or more comfortable. It can sometimes make symptoms worse.

This is a decision for the person's treating team, the person if they can decide, and their substitute decision-maker or family where appropriate. Ask what benefit is expected, what burdens are possible, and what comfort care can be given instead.

General information: This page gives general information for people in Australia. It cannot tell you exactly what is happening in one person's situation. If you have concerns about a symptom, medicine, treatment decision or change in someone's condition, contact their doctor, palliative care team, nurse or other treating health professional.

When fluids may help

Fluids may help when dehydration is making symptoms worse and the person is not in the final phase of dying, or when there is a reversible problem that treatment may improve. For example, a person may be dehydrated after vomiting, diarrhoea, fever or poor intake during an infection.

Even then, the team needs to consider the person's illness, goals of care, ability to tolerate fluid, and whether fluids are likely to improve comfort or function.

Why fluids may not help near death

When someone is dying, the body often cannot handle fluid normally. The heart, kidneys, lungs and gut may be slowing down. Giving fluid through a drip may not fix the underlying dying process.

Extra fluid can sometimes add to swelling, breathing secretions, coughing, nausea, vomiting, discomfort, or the need to pass urine when the person is too weak. A drip can also mean needles, tubes, alarms, monitoring, hospital transfer, or attempts to pull the line out if the person is confused.

This does not mean fluids are never used. It means the question should be: "Will this help this person feel better now?"

Dry mouth is different from thirst

Families often ask for IV fluids because the person's mouth is dry. Dry mouth is common near death and can be caused by mouth breathing, medicines, less saliva, oxygen, dehydration or illness.

IV fluids may not relieve dry mouth. Mouth care is often more useful. This may include moistening the mouth, cleaning the tongue and gums, using lip balm, and offering small sips or ice chips if the person is awake and can swallow safely.

Ask the nurse to show you what mouth care is safe for this person.

Questions to ask before agreeing to fluids

You can ask:

"What problem are we trying to fix with fluids?"
"Is this likely to make them more comfortable?"
"Could fluids worsen breathing, secretions or swelling?"
"Would this need hospital transfer?"
"How long would we try it before reviewing?"
"What would make us stop?"
"What can we do for dry mouth without a drip?"

If the person has an advance care directive or has spoken about drips, hospital transfer or life-prolonging treatment, tell the team.

What comfort-focused care can include instead

Comfort care may include mouth care, careful positioning, medicines for pain or breathlessness, small sips if safe, skin care, eye care, and keeping the room settled. If the person is awake, ask what they want. If they cannot speak, watch for comfort or distress.

The decision is not "fluids or no care". Not giving IV fluids can still be careful, active care when fluids are unlikely to help.

When to get help now

Contact the palliative care team, GP, nurse or aged care staff if the person seems thirsty, has a very dry or sore mouth, has new confusion, repeated vomiting, fever, worsening breathlessness, swelling, or the family is distressed about fluids.

Call 000 if the person has a sudden life-threatening emergency and is not expected to be dying, or if there is no care plan and urgent help is needed. If the person is expected to die and has a plan, follow that plan and call the listed service.
