How long will the typical patient die after stopping fluids?
3-14 days
List 4 nonoral routes of fluids
IVF
SubQ (hypodermoclysis)
Enteral (via NG/PEG/PEJ)
Rectal (proctoclysis)
What are some arguments against
parenteral fluids in palliative care?
- Comatose patients unlikely to feel
- Dry mouth not improved with fluids
- Thirst not improved with fluids
- Reduces voiding
- Reduces terminal secretions risk
- Reduces pulmonary edema risk
- Reduces effusion/ascites accumulation
- Reduces medicalisation at EOL
What are some arguments for parenteral fluids in PC?
- Some patients thirsty at EOL
- Can treat opioid neurotoxicity
- Can treat electrolyte abn (esp. Na/Ca)
- No evidence this prolongs dying
- Relieves family/cultural anxiety
What are contraindications to parenteral fluids in PC?
- Short days/hours of life
- Excessive peripheral edema
- Excessive terminal secretions
- Accumulation of ascites/effusions
- Pulmonary edema
- Request of patient/SDM to stop
What are indications for parenteral
fluids in palliative care?
These assume patient is conscious and prognosis likely >days
- Symptomatic hyperNa+ or hyperCa++
- Delirium expected to respond
- Strong patient/SDM preference despite education around limitations
- Time-limited trial
Describe a serum-Na approach to beginning parenteral fluids
Fluid deficit can be divided into:
- Dehydration (always hyperNa)
- Volume deficit (any Na state)
Treat dehydration w. fluids
Treat volume deficit according to cause
What is a usual volume of fluid daily
required by a terminal patient?
700-1000mL
What are the advantages of IVF?
- Rapid onset
- High volumes
- High bioavailability
- Allows IV-only drugs
What are the disadvantages of IVF?
- Venous access issues
- Limits patient mobility
- Frequent site changes
- Higher infection risk
- Higher cost
- Requires trained personnel
- Ties patient to medical location
What are the advantages of HDC?
- Easy tissue access
- Catheter can remain up to 7 days
- Minimal training required
- Lower bleeding/infection risk
- Patient can remain mobile
- Cheaper
What are the disadvantages of HDC?
Sites can get irritated
More work than no fluids
(BUT generally superior to IVF in PC)
What equipment is best for HDC?
Teflon > steel catheters
Insert at 45* angle to skin, then tape
Pump or gravity infusion
