Q

PQRST

Assessment Questions for External Analgesics

A

Precipitating Factor
is pain related to specific activity?

Quality
describe the pain + other symptoms

Region
localization / JOINT?

Severity

Time

12
Q

When to REFER for
P

in PQRST

A

Precipitating Factor
Is the pain related to a specific activity?

Refer if:
pain occured
after a prolonged period of IMMOBILIZATION
plane&car ride / bedridden / hospitilization

13
Q

When to REFER for
Q

in PQRST

A

Quality
Can you describe the pain?
Are there any other symptoms?

Refer if:

( burn/ tingle/ electrical/ numb) / (limb weakness / swelling/redness)

14
Q

When to REFER for
R

in PQRST

A

REGION
Where is the pain / Localized?
is the pain in or around a JOINT?

Refer if:
Pain follows a nerve path = Shooting pain
if pain in non-localizable = generalized pain
if there is joint redness / tenderness / swelling
if there is prolonged/pronounced STIFFNESS after period of inactivity
if there is joint deformity / abnormal movement

15
Q

When to REFER for
S

in PQRST

A

Severity
how severe is the pain?

Refer if:
If pain is constant and doesnt abate with rest​ of AA
if pain is moderate - severe = >6 on 1-10 scale

16
Q

When to REFER for
T

in PQRST

A

TIME
How long has the pain been present
How Often does the pain occur

REFER if:
pain is present for >10 days
if lower back pain >6 weeks
>7 days after treatment / self care
if pain intensity increases / resolves->reoccurs

17
Q

RICE

Non-Drug Therapy for External Analgesics

A

REST
Stop offending activity / avoid using are / use immobiling techniqiues

  • *ICE**
  • *Post Injury:** Apply for first 12-24 hours = 10 min 4-6x a day
  • *Non-Acute:** use HEAT/moist heat for 20 min every 2-4 hours
  • do not use on INFLAMMED areas or w/ counter irritants*

COMPRESSION
use bandages / wraps

ELEVATION
elevate injured area @/above level of heart

18
Q

Counter-Irritant External Agents

general info

A

Prduce acute analgesic benefit in appropriate musculoskeletal conditions
minimal efficacy for chronic pain

4 GROUPS

_Although all are applied topically:_
there is some systemic absorption
serious toxicity after EXCESSIVE use esp in children
<2 y/o, no FDA approved agents

19
Q

RUBEFACIENTS

Group A

External Analgesics

A

Produce redness & warmth with mild inflammation due to
VASODILATION“rubefAAAcients” = redness/warmth/inflammation

Methyl Salicylate
(wintergreen oil)
may have systemic effects,
DNU in children + _asprin/salicylate ALLERGY_

Other agents:
Ammonia water / allyl isothiocyanate / turpentine oil = Vicks/Sloans

20
Q

Group B

External Analgesics

A

Produce COOLING SENSATIONB-Cool

Menthol
commonly used on its OWN = Bengay / biofreeze

Camphor
typically used w/ menthol = tiger balm
smell / avoid use in infants / young children

21
Q

Group C

External Analgesics

A

Induce VASODILATION
“vasCodilation”

Histamine Dichloride
Australian dream pain relief

Methyl Nicotinate
found in new combo products

22
Q

Group D

External Analgesics

A

Substance P Depletors
“D-epletors”
do NOT cause redness / vasodilation
Acute use –> release substance P = NT for pain perception
Chronic use –> depletes substance P = decreased pain perception

  • *CAPSAICIN / Capsicum /** Capsicum olersin
  • *Zostrix / Capzasin** HP Lotion / Cream
23
Q

Substance P Depletors

Indications

A

Depletors = Group D external analgesics

  • *Acute** use: found in combo products, limited data
  • *Chronic Disorders**
  • *DM** Neuropathy / Post-Herpetic Neralgia (shingles=herpesZ)

Arthritic Conditions = reduce PAIN, not inflammation
only for HAND OA

24
Q

Substance P Depletors

Instructions

A

Depletors = Group D for CHRONIC USE:

Apply 3-4 times QD on a SCHEDULED BASIS, not PRN

onset is SLOW
Arthritis pain = 1-2 weeks
Neurologic Pain = 2-4 weeks

pain relief MAY persist for several weeks AFTER d/c
may INITIALLY cause increased pain/burning = 72 hours

DO NOT USE ON BROKEN SKIN

25
Q

Product SELECTION guidelines for:

External Analgesics

A

do NOT select products w/ ingredients from the same class/group
except for MENTHOL + CAMPHOR = Group B-cool

READ LABELS carefully
​many brand line extensions w/ diff ingredients
look for both active & inactive ingredients
can be problematic if h/o of allergies / ADR

DO NOT USE Counterirritants w/
Topical anesthetics / antipruritics / skin protectants

26
Q

Trolamine Salicylate

External Analgesics

A

Found in Aspercreme / Blue-emu

OTC CAT 3 for efficacy, might have systemic absorption

Has same DI’s as SALICYLATES
avoid in patient with ANTICOAGS / OTHER salicylates

27
Q

Topical NSAIDS

External Analgesics

A

Diclofenac = RX only, only FDA-approved agent

Allows for localized NSAID treatment
similar benefit to ORAL NSAID

  • *AAA BID**
  • rash / topical pruritis*
  • expensive = cos issue*
28
Q

Formulation Considerations of

External Analgesics

A

Liniment / Ointment
application w/ friction or massage = therapeutic benefit

Gel
increased warmth / systemic absorption

Lotion
RAPID / uniform application + okay for hairy areas

Patch
up to 4 patches /24 hours

Spray
easy application to large areas

29
Q

Patient Education

External Analgesics

A

do NOT apply to broken skin
or use with heating pads / hot water bottles / heat wraps
