pain pathway
transduction
transmission
perception of pain
modulation
WILDA
Words Intensity Location Duration Aggravating and alleviating factors
soft tissue involvement, musculoskeletal
ache, throbbing
somatic
somatic pain is responsive to
NSAIDc/COX-2
opioids
involves organs, referred pain
cramping, pressure, tightness
visceral
visceral pain is responsive to
NSAIDs/Cox-2
opiods
numbness, tingling, radiating, burning, shooting
neuropathic pain
nerve involvement
neuropathic pain is responsive to
mildly to opioids
anticonvulsants
Antidepressants (TCA)
short term
episodic
physiological changes
acute
long term, baseline pain
breakthrough pain
no objective physiological signs
chronic
the simultaneous use of different analgesic agents or forms of analgesic delivery that suppress pain transmission in the peripheral and CNS
can be designed to inhibit the release of noxious mediators, block conduciton in sensory nerves, suppress pain perception in the CNS
Multimodal Analgesia
acetaminophen
NSAIDs/Cox-2
non-opioids
unless contraindicated, any analgesic regimen should include ________ even if pain is severe enough to require the addition of an opioid
non opioid
non-opioid of choice for patients with renal disease
Acetaminophen
tylenol
extremely useful in pain that involves inflammation
adverse effect profile, GI, renal and CV
drowsiness and confusion common in elderly
non selective NSAIDs
do not directly provide analgesia
used more extensively in chronic pain than acute pain
help with suffering
adjuvant medications
antidepressants
anticonvulsants
benzodiazepines
muscle relaxants (short term use only)
selected adjuvant medications
used for mild to mod pain
usually given in combination with non opioids which limits doses
rarely appropriate for post op pain or chronic pain
short-acting - used for rescue or pre-eptive
codeine, hydrocodone, oxycodone, tramadol
combination (weak) opioids
used for moderate to severe pain
no maximum dose
can be given by many different routes
long-acting forms available for chronic pain
single-agent opioids
paravertebral blocks for
thoracotomies
thoracoscopies
lung biopsy
interscalene block
total shoulder arthroplasty
provides continuous infusion of a local anesthetic at the surgical site
portable and requires little management by caregiver or patient
Peripheral nerve catheter PNC
frequency of side effects such as nausea, vomiting, constipation, and sedation are reduced
places medication directly onto the cerebrospinal fluid
implantable (intrathecal) pumps
delivers low voltage electric stimulation to the spinal cord to block the sensation of pain
neurostimulator
