16
Q

neuropathic pain factors

A

does not have to occur w/ inflamm

abnormal processing of stimuli

17
Q

neuropathic pain peripheral mech

A

neuroplasticity

damage nerve endings= abnorm firing

18
Q

neuropathic pain central mech

A

neur become hyperactive

inc response to stimuli

19
Q

pain assessment components

A
self- report- pt most important source
location
intensity
quality
onset-duration
aggravating and relieving factors
effects on quality of life
comfort-function goal for pain
20
Q

pain management techniques

A

multimodal pharmacologic
multip. diff meds or nsaids w/ opioid or w/ distraction and imagery

PCA
continuous dose w/ option for bolus
entirely patient controlled

21
Q

pain medication routes

A

oral pref- need to be able to swallow and intact GI tract

transfer off IV ASAP- dec risk infection, reach discharge goals faster

22
Q

NSAID patho

A

dec pain by inhib COX enzymes

23
Q

Opioid patho

A

act on CNS inhibit act. ascending nociceptive pathways

24
Q

local anesth. patho

A

nerve block

25
Q

analgesic agents- nonopiod

A

mild to moderate pain
acetaminophen
nsaids-
side effects- GI bleeding, peptic ulcer

26
Q

analgesic agents- opioid

A

Mu agonist- morphine, fentanyl, oxycodone
act dopamine release
agonist-antagonist- buprenorphine, nalbuphine
side effects- confusion, LOC changes, inc falls, respir depression
3-5 day trtmnt recommended

27
Q

Monitoring for OIRD 1st step

A
id pt at risk
obstructed sleep apnea
obesity hypoventilation syndrome
prior experience w/ acute opioid trtment
pre-existing chronic pain
28
Q

monitoring for OIRD

A
cont. ox
capno for those on o2
(ETCO2 lvl change before O2 changes)
20-30 min monitoring after parenteral, 1-2 hrs after oral
sedation scales
29
Q

excessive sedation ORID response

A
hold opioids, notify provider
stimulate pt
monitor trends
rapid response team
naloxone- goal pt alert , rr >10
30
Q

physical dependence

A

dev w/ in 3-5 days
normal response w/ use opioids 2+ wks
manifested by withdrawl symptoms

31
Q

addiction 4C’s

A

compulsive use
cravings
loss of control
conseq. after use

chronic, relapsing, treatable
influenced by genetics, psychosocial and environment

32
Q

nerve blocks

A

multimodal
help manage pain post
12-18 hr duration
blocks motor/ sensory function

assess for circulation, sensation, motor function and skin breakdown

33
Q

adjunctive analgesics

A

local anesth- lidocaine patch
anticonvulsants- gabapentin
antidep- TCAs and SNRIs

34
Q

gerontologic considerations

A

sensitive to sedation and CNS effects
start w/ lose dose
inc risk NSAID- induced GI toxicity
opioid dose dec 25-50% due dec renal func

35
Q

nonpharmacologic methods

A
natural products- herbs, vitamins
mind/body- yoga, massage therapy
positioning
heat/cold- about 20 min
range of motion
36
Q

nursing process for pain

A
id goals (educated realistic options)
est. nurse-pt relationship
provide physical care
manage anxiety r/t pain
evaluate pain management strategies continually
