Constant, dull, aching, localized, changing with movement pain
Somatic
Deep, aching, cramping, poorly localized pain
Visceral
Burning, shooting, tingling, or shock-like pain
Neuropathic
Pain levels expected to interfere with function and sleep
Moderate (4-6/10) or greater
Pain levels expected to interfere with concentration
Severe (7-10)
Opioid selection in renal insufficiency?
Fentanyl and methadone
Opioid selection in hepatic insufficiency?
Fentanyl, hydromorphone, oxycodone, and methadone with caution
Methadone receptor profile
Mu and delta receptor agonist, NMDA receptor antagonist
Methadone re: serotonin
Inhibits reuptake
Methadone re: norepinephrine
Inhibits reuptake
Methadone Absorption
Lipophilic, Through the stomach, No transdermal application
Methadone Metabolism
Hepatic, with no known active metabolites
Methadone Elimination
Fecal
Methadone EKG effects
QT prolongation
Nociceptive Pain Mechanism
stimulation of intact pain receptors and transmission along normal nerves
Nociceptive Pain Prevalence
Most common type of pain
Nociceptive Pain Quality
aching, throbbing, sharp
Nociceptive Pain Examples
arthritis, myofascial pain
Neuropathic Pain Mechanism
injury to or disease of peripheral or central nerves
Neuropathic Pain Prevalence
Less common and often more difficult to treat
Neuropathic Pain Quality
tingling, burning, electrical, lancinating
Neuropathic Pain Examples

30%
% of elderly with constant pain with regular pain medication available?
less than 1/3 (33%)
Verbal Agitation
High association with pain or other physical symptoms
PQRST of Pain History “P”

Temporal patterns
piper methysticum (Kava Extract)
Effective in treating anxiety, causes Hepatotoxicity
Cognitive Behavioral Therapy
Best risk/benefit ratio for insomnia. Better than relaxation techniques.
Opioid Induced Neuroexcitability Symptoms
Increased Agitation, Hyperalgesia, Agitation
Aspiration pneumonia
Most common mechanism of death in dementia
Opioid Related Nausea
Try antiemetics, then rotate opioids
Complication from Transjugular Intrahepatic Portosystemic Shunt
Encephalopathy
Absence of pupillary or corneal response
High predictor of mortality in comatose patients

MRI for patient with worsening back pain
Malignant Spinal Cord Compression Treatment
Surgery followed by radiation

No
