Q

Nausea + vomiting causes?
(3B’s + examples)

A

3 B’s:
1. Bowels - constipation, infection, obstruction, mucositis

  1. Brain - Raised ICP
  2. Biochemical - Meds (e.g. opioids), hypercalcaemia, infection, uraemia

Q

Central + 4 surrounding systems that play a role in vomiting + their receptors

A

ALL FEED INTO VOMITING CENTRE - 5HT3, H2, ACh

  1. Chemoreceptor trigger zone (CMT) - 5HT3 + D2

2.Gut wall - 5HT3

  1. Limbic system/Higher centres - Neurokinin 1 + GABA + 5HT3
  2. Vestibular system - H1 + muscAch

Q

How do causes (3b’s) + systems of vomiting = cause it?

A

Gut wall –> distension stimulates vagus - constipation, chemo, obstruction = stimulates enterochromaffin cells

Chemoreceptor trigger zone - uraemia, drugs, chemo, hypercalcaemia

Vestibular system –> vertigo+motion sickness

Limbic system –> emotion + hyponatraemia

Q

Name some antiemetics + which nausea cause (3B’s) they work on.

What is most often used first-line in palliative care + why?

A

Bowels only:
Domperidone (D2)

Bowels+Brain
Ondansetron (5HT3)
Metoclopramide (D2)

Biochemistry+Brain
Haloperidol (D2) - EPSE!!
Levopromazine (D2, H1, 5HT3, Anti-musc)

Brain only:
Cyclizine (H1, Antimusc)

RECEPTORS ALL A BIT BOLLOCKS - SO DON’T WORRY ABOUT ‘EM

Haloperidol used 1st line - as acts on CTZ = outside blood-brain barrier. Opioids are commonly used in palliative care patients and don’t cross blood-brain barrier, so haloperiodol is good at prevent nausea from these.

Q

Why shouldn’t you prescribe cyclizine + metoclopramide?

A

C = constipating

M = Diarrhoea (as is a prokinetic)

the 2 counteract each other in the bowels

16
Q

How much PRN dose should you give (if giving modified release)

A

1/6th of daily dose

17
Q

What to prescribe alongside opioids? Why?

A

Stimulant+softening Laxative

PRN antiemetics

SIDE EFFECTS = common

18
Q

OPIOIDS

Common SE?
Less common/Serious SE?

A

Common:
Constipation, sedation, nausea, dry mouth

Less Common:
Myoclonus (jerky movement) - look for sippy cup instead of mug for tea
Confusion

Rare
Resp depression
Pruritus

19
Q

Morphine - dose adjustments for oral –> IV/SC

A

Morphine SC/IV = 2x oral

20
Q

Examples of morphine / oxycodone for background + breakthrough pain?

A

Background - modified release:
-MST (tablet) - morphine
-Zomorph (Capsule) - morphine
-Oxycontin - (oral) oxycodone

Breakthrough - immediate
-Oramorph (liquid) - morphine
-Oxynorm (liquid/tablet)

21
Q

What can reverse opioids? When to give?

A

NALOXONE
RR<8
SpO2<92%

22
Q

Renal impairment + Morphine/Oxycodone

A

Renal impairment due to accumulation of morphine

Can use oxycodone with renal impairment = as excreted by kidney differently - doesn’t accumulate

23
Q

Patient taking morphine = renal impairment - options?

A
  1. Reduce dose/frequency
  2. use renal-friendly option:
    -Fentanyl (e.g. patch)
    -buprenorphine
    -Methadone
    -Oxycodone
24
Q

When to use fentanly?

A

-Renal impairment
-For background pain
-If patient cannot take oral medication - it’s a PATCH

Not good though - as conversion charts from morphine–>fentanyl = not precise

25
Q

Adjuvants? Classes + what they’re used for + example

A

Neuropathic Pain:
-Antidepressants - amitryptilline
-Antiepileptics - pregabalin, gabapentin

Muscle spasms:
-Antispasmodics - baclofen
-Benzodiazepines - diazepam, clonazepam

Bone Pain
Bisphosphonates - zoledronic acid

Compression symptoms (e.g. spinal cord compression/^ICP)
Steroids - dexamethasone

26
Q

Key concepts in terminal care?

A

Advance care planning
DNACPR (medical decision, but should be informed)

27
Q

What does advance care planning involve?

A

Advance statement/decision
Power of attorney
Advanced decision refuse treatment - MUST SAY that refusal may shorten life
Preferred place
Bucket list for patient

28
Q

Symptoms/Change that may signify dying?

A

A

Softener (docusate) + stimulant (Senna)
