Q

how might we manage dyspnoea in a palliative setting?

A
  1. treat any easy reversible causes
  2. reassurance/relaxation techniques/environmental modifications/change in position
  3. morphine!
21
Q

what is a common presentation of hypercalcemia associated with malignancy?

A

A patient can present initially with confusion or a more pronounced delirium, but nausea and vomiting, constipation, thirst, or polyuria, may also indicate hypercalcaemia, as can increasing pain.

22
Q

how might we acutely manage hypercalcaemia associated with malignancy?

A

admission to hospital
fluid resuscitation!
bisphosphonate infusion
management of other symptoms if relevant such as delirium with anti-psychotics

+/- calcitonin infusion if severe hypercalcemia
last resort therapy- dialysis

23
Q

as a doctor managing the palliative care of a patient, what are some key things you must address with the patient and family?

A
  1. Explain the concept of palliation and explain common misperceptions about it (e.g. it is still active care). Explain that death is a normal process of life.
  2. Explain the options available for palliative care e.g. community/hospice/hospital
  3. Develop goals of care with the patient and family. Consider cultural views, religious views
  4. If competent and relevant, organise an advanced care plan
  5. Talk about other legal issues including POA etc
  6. Provide ongoing emotional support for family/carers and patient, and throughout the grieving process
24
Q

what drugs can we use to manage constipation in the palliative setting?

A

Soft faeces in rectum- propulsive agent like bisacodyl or senna

hard faeces in rectum- stool softener (docusate) and propulsive agent like bisacodyl +/- macrogol (movicol)

faecal impaction- rectal lubrication like glycerol suppositories and stool softener docusate. Can either manually disimpact under midazolam or use macrogol

refractive opioid induced constipation= methylnatrexone!! (Subcut)

prophylaxis constipation- coloxyl and senna

25
Q

why might osmotic laxatives may not be the best option for constipation in pall care?

A

draws fluid into the bowel, which is not good for a patient who has poor fluid intake… however saying that we can still use theml if we deem they are required

26
Q

if we suspect that constipation is causing intestinal obstruction, what type of aperiant might we suggest?

A

docusate or softening enemas only

27
Q

how might we manage constipation in a patient with paraplegia?

A

encourage to try to defecate after meals; use a rectal propulsive suppository (bisacodyl) at that time

or try an enema like microlax after breakfast every 2nd day

28
Q

what is the best antiemetic for chemotherapy/radiotherapy induced nausea?

A

ondanestron!

29
Q

when might we NOT use metoclopramide for a palliative patient with nausea?

A

metoclopramide contraindicated in bowel obstruction so if you have a strong suspicion of BO do not use metoclopramide

30
Q

what are some general causes for nausea in a palliative patient?

A 
anxiety
reduced gastric motility
metabolic imbalances--> affect CTZ 
intracranial cause
gastric reflux
nausea from drugs/chemotherapy/other treatments
31
Q

what are some alternative, less commonly used options for N+V in a palliative patients other than metoclopramide and stemitil?

A

you can try antipsychotics such as haloperidol/chlorpromazine/olanzapine, and dexamethasone

also think about adding a PPI or stopping NSAID for gastric reflux

32
Q

why might fentanyl not be a good analgesic agent for a cachetic cancer patient?

A

Fentanyl usually is administered subcutaneously and is lipophillic, and if the patient is severely cachetic and does not have a lot of subcutaneous tissue it may not be effective

33
Q

what are some factors you need to continually monitor in a palliated patient who is on opiate medication?

A

RR
O2 sats
Level of drowsiness/sedation
Bowels open?
N+V
previous opiate addiction/chronic use or opiate naive?
how many breakthrough doses were required?
Does the administration method need to be changed?

34
Q

what is an important SE of ondanestron

A

constipation

35
Q

describe the management of BO in palliative setting?

A

generally you have a higher threshold for surgery and try supportive measures first to rest the gut.

NBM
Fluid resuscitation +/- NGT (drip and suck)
Syringe driver- morphine, cyclazine, hyoscine butylbromide
+ dexamethasone

+/- ranitidine
+/- octreotide

36
Q

what may indicate that a patient may have faecal impaction versus faecal loading

A

faecal loading is essentially a rectum full of faeces. It is the consequence of a chronic course of constipation.

faecal impaction is acute onset, and technically a bowel obstruction. You should look for signs for bowel obstruction such as tympanic bowel sounds etc

37
Q

what is generally the dosing schedule for metoclopramide?

A

metoclopramide 10mg 3-4 times a day

can increase to 20mg QID (so usually max dose is 80mg)

38
Q

what type of anti-emetic is good for colic pain and why?

A

cyclizine

reduces bowel peristalsic spasms; promotes GIT stasis

39
Q

what are some causes of nausea and vomiting in palliative patients with advanced cancer?

A 
gastric stasis
biochemical disturbances
raised ICP
vestibular causes
bowel obstruction
psychological

often these are due to a combination of direct cancer effect, drug induced or comorbid organ failure and debility( e.g. cachexia/pain/constipation)

40
Q

what are some IX you would do for a palliative patient with N+V

A

Bloods- rule out sepsis or infection, renal failure, hypercalcemia so FBE/MSU, UEC, CMP, eGFR

Imaging- may consider an AXR if suspect bowel obstruction/faecal loading

41
Q

Describe some practice principles about prescribing anti-emetics in a palliative care patient for N+V

A

For straight forward cases of N+V:
Generally try a dopamine antagonist agent first; titrate to effect. Then if refractive, add on another anti-emetic that covers different mechanisms. Usually an empiric approach is justifiable.

If there are certain reasons for N+V such as bowel obstruction/chemotherapy/other medications, manage these and choose targeted anti-emetics (e.g. avoid metoclopramide in BO etc)

42
Q

for older patients, what do you need to think about before prescribing metoclopramide for their N+V?

A

their renal function; if impaired may need to dose reduce accordingly

monitor for EPSE

comorbid conditions such as PD, ESRF etc

43
Q

when should prochlorperazine be avoided to treat N+V?

A

if the patient is neutropenic

44
Q

how might we confirm a death?

A
  1. Go get and look at the patient’s notes
  2. Explain to the family members (if present) the need to confirm a death + condolences
  3. Go to patient and see if responsive. Take the hand and say ‘can you hear me?’ and squeeze. Can squeeze the trapezius muscle/inner part of the elbow.
  4. Look for chest rise and fall.
  5. Palpate the carotid pulse
  6. Listen to the heart for 2 minutes.
  7. Listen for breathing sounds for 2 minutes
  8. Check pupillary reflex (should be dilated and unresponsive)
  9. Write examination findings into the patient note and the time.
  10. complete death certificate or call the coroners if relevant.
  11. Contact the NOK.
45
Q

what are some signs a patient is approaching death?

A

peripheral shutdown and cyanosis
changes in respiratory pattern inc cheyne stokes
fluctuations in consciousness
retained upper airway secretions

46
Q

what are some palliative things we will consider as a doctor if we know a patient is dying?

A

If not already- transfer to appropriate palliative accomodation, whether as an inpatient or in the community with palliative care nurses/service

  1. Medication review- remove any unnecessary drugs, symptom control drugs
  2. Change meds from oral to SC
  3. Prepare subcut syringe driver
  4. Family meeting
  5. Liaise with GP
  6. Spiritual support if required
  7. Support for the family
  8. Do not resuscitate in progress notes
47
Q

which analgesics can be used in a palliated patient with ESRF?

A

paracetamol
fentanyl
methadone
bupremorphone

dose reduced oxycodone, hydromorphone

48
Q

what is a syringe driver?

A

A syringe driver is a battery-driven portable device that allows a 24-hour infusion of compatible medications to be infused evenly via a subcutaneous butterfly needle.
