Palliative Care and Pain Management Flashcards
Converting from one opioid to another, change in dosage
decrease by 25% if well tolerated
dosing of prn opioid
10-20% of 24 hour dose
3:2:1 rule of opioid conversion
1mg IV morphine, 2mg PO oxycodone, 3 mg PO morphine
SPIKES- S
setting up
SPIKES - P
obtaining patient’s perspective
-
SPIKES - I
obtain the patient’s invitation
SKIPES - K
giving knowledge and information to the patient
SPIKES - E
address EMOTIONS with EMPATHETIC responses
SPIKES - S (final)
Strategy and Summary
VOMIT - V
Vestibular
Cholinergic and Histamine Receptors
Scopalmine patch, promethazine
VOMIT - O
Obstruction of Bowel By Constipation
stimulate mesenteric plexus - senna
VOMIT - M
Dysmotility of upper Gut
Cholinergic, Histamine 5HT3/4
Prokinetics- metoclopramide
VOMIT- I
Infection, Inflammation
cholinergic, histaminic, 5ht3, neurokinin 1
Promethazine, prochloperazine
VOMIT - T
Toxins stimulating chemoreceptor trigger zone in the brain (including opioids)Dopamine 2, 5HT3
prochloperazine, haloperidol, ondasteron
opioid receptors
mu, delta, kappa
also sigma, epsilon
Somatic Pain
well localized
aching, squeezing, throbbing, stabbing
ex bone pain
Visceral Pain
diffuse, poorly localized
dull, crampy, achy
codeine
weak opioid, metabolized in liver to morphine
many people are slow metabolizers
Methadone- MOA
mu opioid receptor
N-methyl-D-asparate (NMDA) receptor antagonist
Hyperalgesia
increased sensitivity to pain
Allodynia
pain w/ non-painful stimuli
Bone Pain treatment, consider
bisphosphonate
calcitonin
steroids
radiotherapy
Bowel spasm treatment, consider
octreotide, anticholinergic
Tramadol MOA
weak opioid (mu receptor)
NERI
alpha-2 agonist
Ketamine MOA
NMDA receptor antagonist
mu, delta, kappa
serotonergic, noradrenergic, cholinergic
