B6.032 Prework 4: Analgesics and muscle relaxants Flashcards
describe nociceptive pain
well localized pain between costal angles and gluteal folds
describe neuropathic pain
radiculopathy
leg pain associated with numbness/tingling following specific nerve tissue involved
musculoskeletal pain
involves somatic tissues
intermittent, sharp, achy, tender
changes with position and posture
examples of MSK pain
disc pain facet lock ligament injury muscle strain arthritis
treatment of MSK pain
responds well to opioids and NSAIDs
may also respond to steroid, muscle relaxants, and some antidepressants
visceral pain
involves solid organs
pressure, tight, crampy in nature
doesn’t change with position and posture
poorly localized, may refer to other areas
examples of visceral pain
AAA
GI, pelvic, or kidney conditions
treatment of visceral pain
responds to opioids and NSAIDs
may respond to steroids and antispasmodics
neuropathic pain
results from damage to nerve tissues
intermittent sharp, shooting, burning leg pain, night pain, muscle weakness
examples of neuropathic pain
cord compression spinal stenosis radiculopathy sciatic pain peripheral nerve injury
treatment of neuropathic pain
responds poorly to opioids
may responds to TCAs, SNRIs, anticonvulsants, or topical local anesthetics
commonly recommended pharm treatment for nociceptive pain
APAP
NSAID
muscle relaxants
non-opioid recommended
degree of evidence for APAP in back pain
fair
inferior to NSAIDs
best for people w renal disease
use of muscle relaxants in acute back pain
generally not 1st line unless severe
short term use only in most
works through CNS
examples of muscle relaxants
diazepam
methocarbamol
etc.
