Pain Management Flashcards
How can the three stage model explain pain patterns in EOL care?
- they face the threat of death
- there’s a universal depression once they know the disease will cause death
- they develop coping mechanisms and accept imminent death
pain occurs in 2
In what way should treatment be matched to pain?
match it to timing, duration and pattern
you don’t want to overtreat it!
Describe the WHO pain ladder.
- start with non opioid
- add an adjuvant specific to type of pain
- add opioid
after that - increase the opioid
What sort of drug administration should you start with?
enteral! if the gut workse, use it
oral, buccal, sublingual, rectal
Describe the “pain code”
treat pain as an emergency
get the patient comfortable as fast as safely possible
don’t “walk away” from a patient untilt hey’re comfortable
typical dosing of drugs is based on what?
half life
Describe dosing by maximum blood concentration
if the first dose doesn’t work, you redose at the PEAK of the pain control and keep doing that until you get up to the optimum blood concentration - after that you can space out doses
What’s the equivalent dosing between morphine IV and morphine oral?
3x
What’s the equivalent dosing between hydromorphone oral and morphine oral?
mutliply the hydromorphone by 4 for the morphine oral
What’s the equivalent dosing between hydromophone IV and hydromorphon oral?
multiple IV by 5
What are the concenrs about methadone?
stigma in community
abuse poential
difficult to dose
long QT syndrome
Why should you never use a dose converter to dose methadone?
because it’s not linear - it will have different effects at different concentrations
How does methadone differ from other opiates in terms of kinetics?
very long half life, so slow on, slow off (four days)
At what dose of methadone should you check and EKG?
30 mg
What are the side effects of the opiates?
constipation nausea delirium myoclonus urinary retention itching hyperalgesia
