Invasive therapies for Pain mgmt
***Trigger Point Injections
good for focal pain!!!
Not super invasive!
*Joint Injections
we don’t do these in ER for pain control.
Lots of PCPs do- it’s a good idea!
*Regional Nerve Blocks
we will be better at these than providers before us!
*Epidural Injection
later line
*Various Surgeries
APAP 1* MOA
Inhibit the syntheses of prostaglandins in the central nervous system
APAP other MOA
*Works peripherally to block pain impulse generation
Does APAP do anything for coag pathways?
No
Does APAP inhibit plt funciton?

ASA 1* MOA
↓ prostaglandin and thromboxane A2 synthesis
Does ASA ↓ platelet aggregation
yes!
How does ASA inhibit plt function?
Irreversibly inhibits platelet function for the life of the platelet, interfering with hemostasis and prolonging bleeding time
ASA:
Caution with (3)
Gastrointestinal tract injury/upset
Renal injury
Viral syndromes in children and teenagers
-risk of Reye syndrome
A single does of ___ can precipitate Asthma in ___ sensitive pts

“MOM”
Migraine
OA
Muscle pain
NSAIDS MOA:
Nonselective
Inhibit cox-1 and Cox-2
NSAIDS MOA:
Selective
Only inhibit COX-2
7 Nonselective NSAIDS
Non selective about dinner-“DINES IN”
Diclofenac
Ibuprofen
Naproxen

Dysmenorrhea
Migraine
Tension HA
Muscular pain
Tendionous pain
Sprain/Strain
T/F: NSAIDS can be used in pregnancy
NOope
How do NSAIDS decrease pain with menses?
NSAIDS slow down prostaglandin production→less uterine shedding→ fewer cramps & less bleeding
T/F: You can use NSAIDS after a fx to reduce pain
No! esp scaphoid fx and fx at risk for malunion
6 conditions you cannot use NSAIDs with:
Fracture pain
Pregnant women
Known history of PUD
Renal dysfunction
Bleeding disorders
Uncontrolled HTN

T/F: NSAIDS delay healing
True
Adverse Effects of NSAIDS
(AABCDEFGH)
AA- anaphylaxis in ASA sensitive pts & Asthma precipitation
B- BP (HTN)
C- Coag probs (inhibit plts)
D- DM and renal failure (Naproxen)
E- Exacerbate CHF
F- failure of kidneys
G- GI bleed/ulcers/perforation
H- Hepatotoxicity
How do NSAIDs cause renal failure or HTN?
↓ synthesis of renal vasodilator prostaglandins
and ↓ renal blood flow
→ fluid retention
