tricyclic intidepressant (TCA) antiepileptic (pregab, gabapent)
Other options include ketamine
How to treat neuropathic pain due to nerve compression
corticosteroid such as dexamethasone (reduces oedema around the tumour)
Also consider nerve blocks & regional anesthesia (e.g. epidural) if pain is localised
frequensy of morphine:
immediate release
modified release
immediate 4 hourly
modified 12 hourly
how long before an activity that causes pain should a breakthrough pain dose be given
30 mins
dose for breakthrough pain should be …
how often to reapeat dose?
1/10 to 1/6 of total 24 hour dose
2-4 hourly, up to hourly in needed
if they need breakthrough dose. ……. times a day the regular dose should be reviewed
2
increments of increase of morphine should not exceed
one half to one third of total 24 hour dose
how to transfer patient from immediate release to modified release morphine
four hours after immediate release dose give the modified release dose (with same 24 hour total dose)
when adjusting morphine do we adjust the dose or the frequency
dose
oral to parenteral morphine convertion
parenteral is about half oral dose
what is the route of admin of syringe driver
SC
why is diamorphine sometimes preferred in syringe driver
more soluble
equlvilent S/C dose of diamorphine is about ……. of the dose of oral morphine
a third
transdermal route is not suitable for what sort of pain
acute and pt who analgesic requirements are variable
when switching to transdermal patch due to opioid induced hyperanalgesia how much should the dose be reduced by?
1/4 to 1/2
anorexia symptom control treatment (2)
dexamethasone or prednisolone
symptom relief for bowel colic and repiratory recretions
S/c hyoscine hydrobromide, hyoscine butylbromide, or glycopyrronium (antimuscurinics)
(4 hourly up to hourly)
symptom treatment - capillary bleeding (3)
tranxeamic acid PO
or tranexamic acid or adrenaline solution soaked gauze to affected area
vit k ( for liver disease)
opioid induced constipation in palliative care
PREVENTATIVE -codanthramer (peristaltic stimulant & fecael softener) -lactulose and senna also -methylnaltrexone
prophylactic treatment for convulsions in palliative care
phenytoin or carbamazapine PO
rectal diazepam
phenobarb injection
midazolam syringe driver
dry mouth non pharma treatment
sucking ice, chewing gum, sucking pinapple chunks
artificial saliva
what to consider as a cause of dry mouth
too much antimuscurinic (e.g. hyoscine) candida infection (nystatin, miconazole, fluconazole treatment)
dysphagia caused by obstruction with tumour could be treated with
dexamethasone
breathlessness can be relieved with
PO morphine
diazepam if due to anxiety
corticosteroid if bronchospasm/obstruction
fungulating tumours treated with
dressings
metronidazole systemically for malodour

If this fails BZs could be considered such as temazepam
Intractable cough should be treated with ….
And you should NOT treat with …
