Palliative Medicine Flashcards
What is the PAM index?
Pre-arrest morbidity - looks at whether CPR will work (clinical team’s decision when deciding the efficacy of CPR in DNACPR decision)
(Common Pain syndromes)
Mx of Bone Pain?
- NSAIDs (e.g. diclofenac)
- Radiotherapy
- Bisphosphonates (e.g. pamidronate infusion)
(Common Pain syndromes)
What is Visceral pain?
Dull, deep-seated, poorly localised pain. May be tender over particular organ. Some visceral pain is spasmodic such as bladder spasm/ bowel colic.
(Common Pain syndromes)
Mx of different types of visceral pain?
- Constant pain: follow analgesic ladder
- Visceral stretch (e.g. liver capsule pain): NSAIDs/ corticosteroids (reduce inflam)
- Colic pain: anticholinergic drugs e.g Hyoscine butylbromide for bowel colic, or Oxybutunin for bladder spasm.
(Common pain syndromes)
Management of neuropathic pain?
- Antidepressants (amitriptyline)
- Anticonvulsants (gabapentin/ pregablin)
- Corticosteroids if compression of nerve
What is the 2nd stage on the Analgesic Ladder? (after paracetamol)
Codeine (240mg max)
Co-codamol (8/500, 15/500, 30/500)
Tramadol (not well tolerated in elderly, causes delirium
In pain mx, what must you always prescribe in?
mg !!!!
e.g. Oramorph 10mg/5ml, or 100mg/5ml
Example of Oral Morphine- quick release?
How do you work out the dose? What is the max dose?
How do you prescribe it?
Oramorph liquid/ Sevredol tablets.
-Takes effect in 15-30mins, lasts 4hrs.
Should be 1/6th total daily dose of regular opiate. Max top-up pain is 6 doses in 24hrs!
Prescribing:
- ‘hrly’ in frequency box.
- ‘6doses max’ in extra info box.
Example of Oral Morphine- modified/ slow-release?
Morphine Sulphate Tablets (MST)/ Zomorph capsules
MST is prescribed 12 hourly!!!
Lasts up to 12 hours.
What is the starting dose of MST?
20mg BD (if pt on max strength co-codamol)
Remember- always check the pain is opioid sensitive.
How much more potent than oral morphine is:
a) Parenteral morphine
b) Parenteral diamorphine
a) 2x more potent than oral
b) 3x more potent than oral
How can you administer Diamorphine/ Morphine Sulphate for injection?
Both can be given subcut either as required or as a continuous SC infusion via a syringe driver.
(n.b. the total 24hr SC infusion diamorphine dose should be 1/3 of total 24hr oral morphine)
Duration of action of Fentanyl transdermal patch?
72 hours
Mainly suitable for pts with severe chronic pain already stabilised on other opioids.
Example of a syringe driver, and what are they used for?
McKinley T34
Portable, delivering a continuous infusion of drugs usually via subcut route.
(usually indicated if: cannot swallow, persistent N&V, intestinal obstruction, malabsorption)
Drugs suitable for subcut infusion via a syringe driver? (avoid mixing >3 compatible drugs)
- Diamorphine/morphine sulphate
- Cyclizine (may cause skin irritation)
- Haloperidol
- Metoclopramide (useful prokinetic, avoid if colic)
- Levomepromazine (can cause skin irritation)
- Hyoscine hydrobromide (may cause sedation/ agitation)
- Hyoscine butylbromide (doesn’t cross BBB)
- Midazolam
