| description ?
burning, tingling, electrical, stabbing, or pins and needles

34
Seven Tenants for Conscientious Prescribing of Drugs for Pain ?
1. Remove barriers that render pain management ineffective
2. Never forget the consequences resulting from pain being poorly managed
3. Properly assess pain before prescribing any drug
4. Remember the goal of using medications for acute pain
5. Remember to use different prescribing algorithms for mild, moderate and severe pain
6. Use different algorithms when prescribing for chronic pain
7. There is a role for adjuvant medications
35
Tenant #1 ?
Remove barriers that render pain management ineffective
There are barriers to effective treatment of pain on the part of both the patient and clinician
The stigma of the pain medicines being too strong or harmful
Share concerns about drugs being addictive
Concerns about regulatory agencies like DEA
36
Tenant #2 ?
Impaired function and poor quality life
Depression
Polypharmacy through treatment of other manifestations of pain:
Agitation, confusion, sleep disturbance, false, cognitive dysfunction, decreased socialization, anorexia
**Never forget the consequences resulting from pain being poorly managed**
37
Tenant #3 ?
A detailed history and physical is imperative
“Controlled Substance Act”
-federal law and are scheduled depending upon its medical use and potential for abuse and safety
Pain needs to be identified by its source and type
A complete diagnostic evaluation
Use a standardized pain scale
Discuss with the patient realistic goals of pain control
**Properly assess pain before prescribing any drug**
38
Tenant #4 ?
A primary goal of acute pain management is to restore function as soon as possible and prevent the redevelopment of a chronic pain syndrome
Use different combinations of medicines with decreasing potential for addiction and harm
This applies to acute pain and chronic pain
**Remember the goal of using medications for acute pain**
39
Tenant #5 ?
Use a variety of medications that starts with mild pain and progress using different endpoints and assessments
Start with NSAID’s or creams Ben-Gay
For moderate pain use medications like tramadol or Tylenol with codeine or hydrocodone
For severe pain use higher dose opioids like morphine and Dilauded
**Remember to use different prescribing algorithms for mild to moderate and severe pain**
40
Tenant #6 ?
Pain described as lasting longer than three months
Often includes a significant neuropathic component and usually requires the use of medications to manage chronic pain
Hyperstimulation of NMDA receptors and ultimately decrease the effectiveness of opioids upon the mu receptors
Down regulation of the mu receptors or excessive pre-and post synaptic substance P.
**Use different algorithms when prescribing for chronic pain** - these are tough patients to manage
41
Tenant #7 ?
Medications that may be used for the management of pain but whose primary indication is not for analgesia
May include tricyclic antidepressants, and it involves, corticosteroids, anesthetics, muscle relaxants and antiarrhythmic’s (lidocaine)
