ONCOLOGY - EoL CARE (CPR + ANTICIPATORY DRUGS) Flashcards
What are the 3 classes of analgesia?
Non-opioid
Opioids
Adjuvants
What are examples of weak opioids?
Codeine
Dihydrocodeiene
Tramadol
What are examples of strong opioids?
Morphine
Diamorphine
Oxycodone
Fentanyl
Alfentanil
Hydro morphine
Buprenorphine
Methadone
What are the side efefcts of opioids?
Constipation (very common so always prescribe a laxative)
Nausea and vomiting (always prescribe a p.r.n. Antiemetic)
Drowsiness
Confusion
Hallucinations and delirium
Respiratory depression
What are the symptoms you need anticipatory drugs for at end of life?
Pain
Respiratory secretions
Restlessness and agitation
Delirium
Dyspnoea
Emesis
What is anticipatory prescribing?
Medication prescribed in anticipation of symptoms, designed to enable rapid relief at whatever time the patient develops distressing symptoms.
Outline the management of pain at end of life for a patient not currently taking any medication for pain?
Start by giving paracetamol or NSAIDs regularly for mild pain
If not sufficient then opioids alone or in combination with non-opioid analgesic for moderate pain
If refractory…
Prescribe diamorphine s/c injection in intimidation
If 2-3 PRN doses are required then commence a syringe driver whilst also maintaining injections for breakthrough pain
Review and reassess pain every 24 hours as a minimum
Outline the management of pain at end of life for a patient taking oral morphine?
Convert oral morphine dose to diamophrine s/c (divide 24 hours dose of morphine by 3)
Also prescribe prn diamophine s/c injections for breakthrough pain (1/6th of dose in driver)
Review and reassess pain every 24 hours as a minimum
Outline the management of pain at end of life for a patient on fentanyl?
Maintain fentanyl patch at existing dose and prescribe diamophine s/c prn in anticipation of breakthrough pain (divide strength of fentanyl patch by 5)
If 2-3 prn doses are required in 24 hours then commence diamophine s/c via a syringe driver
Review and reassess pain every 24 hours at minimum
What should you do for a patient in pain at the end of life?
Undertake a pain assessment
- is this new pain?
- does the pain fit with a known pathology?
- look for underlying causes and reverse if possible
- review current analgesia (efficacy and side efefcts)
How much more potent is fentanyl than morphine?
150 times
Why do we treat respiratory tract secretions at end of life?
They cause the death rattle which can be extremely disturbing for the family
How do we manage a patient who does not yet have increased respiratory secretions/death rattle?
Prescribe in anticipation glycopyrronium or hyoscine butylbromide (antimuscarinics)
How should you manage a patient with increased mucus secretions?
Try turning the patient first and explain to the family that the patient may not be distressed by the secretions as they are semi-conscious
Immediately administer glycopyrronium or hyoscine butylbromide and continue to administer s/c PRN doses
How can you manage restlessness and agitation?
First look for a cause and reverse if possible
Prescribe midazolam in anticipation if not yet started
If present then administer midazolam
Second line is levomepromazine (more sedation effect)
