Pain management Flashcards
Analgesics
meds that relieve pain w/o loss of consciousness
adjuvant drugs
assist primary drugs in relieving pain NSAIDs antidepresseants anticonvulsants corticosteroids
Opioids
bind to opiate receptors to relieve pain
Mereridine no long term use - seizures
I - pain, cough suppressant, diarrhea, balanced anesthesia
C - allergy, respiratory depression, elevated intercranial nerve pressure, prego & constipation
AE - CNS depression, NV, itching
I - Alcohol, antihistamines, benzos, MAOI
antidote - Narcan or naltrexone resp below 12
Agonists
bind to opioid pain receptor in brain
Agonist-antagonist
safer
bind to pain receptor, weaker neurological response
antagonists
reverse the effects
Equianalgesic
equlivant pain relief
Fentanyl
0.1 iv = 10mg morphine
schedule 2
Dilaudid (hydromorphine)
schedule 2
1mg iv = 10mg of morphine
Methadone Hydrochloride (Dolophine)
schedule 2
detoxification treatment for opioid addicts
Codeine Sulfate
schedule 2
obtained from opium
antiussive drug
GI disturbance
Morphine Sulfate
protoype for all drugs
high abuse potential
do not give to pple w/head injury
natural - opium poppy
Naloxone Hydrochloride ( Narcan)
pure opioid antagonist
failure to reverse effects may mean its not an opioid overdose
Acetaminophen ( Tylenol)
Analegesic and antipyretic, no antinflammatory blocks pain impulses no more than 3000mg/day possible liver dysfunction and failure antidote: Acetylcysteine regimen
General, local and balanced anesthesia
g- complete loss of consciousness
l- no paralysis of respiratory functions. end in “caine”, and be careful of ‘spinal headache’
b - mixing drugs to give safer dose
anesthetics
drugs that reduce or elimate pain by depressing nerve function
AE - malignant hyperthermia - 104 degrees temp
general anesthetics
Ketamine, nitrous oxide, Propofol ( diprivan)
Paralysis
autonomic activity is lost first, then pain and other sensory functions are lost, then motor activity is lost,
recovery occurs in reserve order (motor, sensory, autonomic)
NSAIDS
A4 properties analgesic, antinflam, antipyr, aspirin-plalete inhibition
do not give to pple w/ vitam K deficiency, or peptic ulcer disease, or aspirin allergy
Aspirin
Salicylates - do not give to children or teens because of Reyes syndrome
administer first sign of MI
Reyes syndrome triggered by viral illness
Gout
urin acid build up
