(Medication in) Palliative care Flashcards
Potential issues with routes of administration
Oral
Subcutaneous
Intramuscular
Sublingual/Buccal
Transdermal
Inhalation
Oral – primary route, use if available and appropriate.
Subcutaneous – preferred parenteral route
Intramuscular –painful. Difficult in cachectic patients.
Sublingual/Buccal – not useful if patient has a dry mouth.
Transdermal – limitations; dose titration can be difficult .
Inhalation – patient co-ordination can be an issue in the final stages.
3 recenprtors involved in vomining (peripherally and in vom centre)
Vomiting centre (all feed into here)- ACh, H2. 5HT2
GI tract (stasis, obstruction, irritation)- D2, 5HT3
Vestibular input (motion sickness) - Ach, H1)
Higher centre (anxiety/ raised ICP) - H1
Cemoreceptor trigger zone ( biochemical e.g. drugs) - D2, 5HT3
Give 3 treatable causes of nausea/vom
Drug side-effects, constipation, severe pain, anxiety, infection, cough, hypercalcaemia, raised intracranial pressure, and bowel obstruction.
Give 4 non-pharma management strategies
- Control odours from colostomy, wounds and fungating tumours
- Minimise sight/smell of food
- Give small snacks not large meals
- Acupressure wrist bands
N&V - Drug group Butyrophenone antipsychotics
example
mode of action
use
S/E(4)
Dose
example - Haloperidol
mode of action - Dopamine (D2 receptors) in chemo-receptor trigger zone
use - chemical causes of nausea (e.g. opioids)
S/E - EPSE, sedation, QT-prolongation,
depression
Dose - 500mcg - 1.5mg/24hr Continuous subcutaneous infusions (CSCI) or PO/SC at ight +/ 4hrly PRN (max 5mg/24hrs)
What common palliative care med causes nausea
opioids
N&V - Drug group Butyrophenone antipsychotics
example
mode of action
use
S/E(4)
Dose
what anti-emetic is used in nausea and vomiting caused by intracranial tumours
dexamethasone
(reduces ICP)
Metoclopramide and domperidone are pro-kinetic anti-emetics ( so useful in gastric dysmotility/stasis). What is the appropriate anti-emetic in refractory (tx resistant) vestibular causes of nausea and vomiting?
olanzapine
Metoclopramide and domperidone are pro-kinetic anti-emetics ( so useful in gastric dysmotility/stasis). What is the appropriate anti-emetic in chemically-mediated causes of nausea and vomiting (e.g. chemo) ?
ondansetron
name 2 anti-muscarinic medications which should not be co-prescribed with metoclopramide/ domperidone
cyclizine, hyoscine
completing confirmation of death
a) what staff should be informed
b) when should the death certificate NOT be issues
- Inform relevant nursing staff of confirmation of death (If not present, nursing staff should inform next of kin )
- Coroner referral?
- If yes – do not issue death certificate & discuss with patient’s consultant
certification of death
1a = the disease/ condition that lead directly to death. what “ conditions” would NOT be acceptable as a sole 1a
- “Failures” as a sole 1a (e.g. heart/kidney/liver/respiratory failure). (EXCEPT: congestive cardiac failure) .
- Asphyxia
- Asthenia
- Cachexia
- Cardiac arrest
- Coma
- Exhaustion
- Old age/frailty ( EXCEPT: in patients >80 years old).
certification of death, Ia .
How would you fill in 2 primary causes of death
- enter them both on the same line, then in in brackets state they are joint causes of death
