1 PAIN MANAGEMENT 101 By: Vicki McCulloch RN, NP & DeAnna Looper RN, CHPN, CHPCA

2 Objectives Identify a step-wise approach to pain management. Identify the WHO Pain Ladder. Identify non-pharmacological pain control measures. Identify adjuvant treatment measures. Identify common myths and truths Identify common side effects and treatment options.

3 Pain Management Principles Use Multi-Treatment and Multi-Discipline Approach Combine opioids with non-opioid medications Non-pharmaceutical approaches Include family and caregiver in planning Include the patient! Coordinate with facility Coordinate with all providers- Primary Care Provider Nursing Home Physician Hospice IDG Members

4 Utilize the WHO Ladder World Health Organization (WHO) analgesic ladder Follow the steps as indicated. Determine if adjuvants are necessary.

5 WHO Pain Ladder STEP 3 Strong opioid for severe pain +/- non-opioid +/- adjuvant STEP 2 Mild opioid for mildmoderate pain +/- nonopioid +/- adjuvant STEP 1 Non-opioid + / - adjuvant

6 Step 1-Mild Pain NON-OPIOID MEDICATION OPTIONS Acetaminophen (Tylenol)-(Paracetamol)-(Panadol) Non-steroidal anti-inflammatory drugs (NSAIDs) Traditional NSAIDS Ibuprofen-(Motrin) Aspirin-(Bayer) Naproxen- (Aleve) Nabumetone-(Relafen) Cox-2 Inhibitors Celecoxib-(Celebrex) Rofecoxib-(Vioxx) Valdecoxib-(Bextra)

7 Adjuvants Antidepressants amitriptyline-(elavil) nortriptyline- (Pamelor) Anticonvulsants gabapentin-(neurontin) carbamazepine-(tegretol) Antispasmodics dicycloverine-(bentyl) scopolamine-(transderm Scop) Steroids prednisone-(deltasone) methylprednisolone-(medrol)

8 Non-Pharmacological Measures Environmental controls Room Temperature Osculating Fan Conservation of Energy Frequent rest periods Aromatherapy vanilla, peppermint, jasmine, citrus Massage Therapy simple back massage to deep muscle massages

9 Non-Pharmacological Measures Physical therapy Frequent position changes Heat, and cold Relaxation, imagery, hypnosis Music therapy Distraction

10 Step 2-Moderate Pain Hydrocodone-(Lortab) Oxycodone-(Percocet) Ultram-(Tramadol)

11 Adjuvants Antidepressants amitriptyline-(elavil) nortriptyline- (Pamelor) Anticonvulsants gabapentin-(neurontin) carbamazepine- (Tegretol) Antispasmodics dicycloverine-(bentyl) (Transderm Scop) scopolamine- Steroids prednisone-(deltasone) methylprednisolone- (Medrol)

12 Step 3-Severe Pain Morphine-(MS Contin, MSIR) Hydromorphone-(Dilaudid) Methadone-(Methadose) Fentanyl-(Duragesic, Actiq)

13 Adjuvants Antidepressants amitriptyline-(elavil) nortriptyline- (Pamelor) Anticonvulsants gabapentin-(neurontin) carbamazepine-(tegretol) Antispasmodics dicycloverine-(bentyl) scopolamine-(transderm Scop) Steroids prednisone-(deltasone) methylprednisolone-(medrol)

14 Common Myths I will become addicted to pain medication Use of opioid will shorten length of life Taking pain medication will mask pain and delay diagnosis Starting pain medication in early stage of disease will lead to lack of options in future

15 Common Myths Patients can not drive or carry out normal activity These might make me drugged out They will cause the patient to stop breathing

16 The Truth In advanced disease patients do not become addicted to opioids. Will not shorten life if used properly and if doses are titrated controlling pain may even lengthen life. Opioid use at an earlier stage of disease does not mean that options later in the disease progression will be used up

17 The Truth Respiratory depression is one of the last symptoms with titration. Sedation can be transient or managed. During chronic use and slow titration normal activity can be maintained and even improved.

18 Common Side Effects & Statistics Constipation up to 80 % Not transient Nausea or vomiting % Often transient lasting 2 3 days Sedation 20 60% Often transient at initiation or dose increase Confusion or hallucinations -No figures available May herald toxicity Myoclonic jerks- Up to 60% (at higher doses) May herald toxicity, check for renal failure (Hall and Sykes 2004)

19 Common Side Effects & Statistics Respiratory depression -Rare in chronic dosing. Stop opioid for a few hours, restart at 30% 50% of dose, use naloxone in mg increments only if respiratory rate,8 10/min Xerostomia Common Exclude candidiasis and other drugs; offer ice, Artificial salivas or pilocarpine may help Urinary retention Rare cholinergic agonists may help Pruritus 2 10 %

20 Treatment for Side Effects Urticaria, pruritus fexofenadine, 60 mg po bid; diphenhydramine, loratadine, or doxepin, mg po q hs Constipation All patients on routine opioids should be started on bowel program unless contraindicated. Start with routine Senna or bisacodyl. Add stool softener If no BM in two days add MOM or lactulose

21 Treatment for Side Effects Nausea/Vomiting Promethazine or Reglan. Difficult to treat symptoms may respond Haldol or Benadryl or Nausea Blocker compounded medication. to

22 Treatment for Side Effects Sedation Opioid-induced sedation usually disappears over a few days as tolerance develops. Ritalin was effective in reducing sedation in 90% of cancer patients. If undesired sedation persists, a different opioid or an alternate route of administration may provide relief.

23 Treatment for Side Effects Delirium (rare) Try reducing dose or changing opioid agent Respiratory depression (rare) Try reducing dose or changing opioid agent Narcan only in severe cases as it can cause withdrawal symptoms in long term opioid users.

24 Tips for Effective Pain Management First choice for severe pain is Morphine Follow the WHO pain ladder Consider NSAIDs and other non-opioids Identify and dispel myths (Hall and Sykes 2004 )

25 Pain Management Tips 101 Use one long acting medication and one short acting for breakthrough pain. Increase the long acting medication if ineffective. Do not crush long acting medications Avoid mixing narcotics Start at the lowest possible dose first.

26 Pain Management Tips 101 Don t wait until pain is severe before starting patient on pain management regimen. Consider ATC dosing. ALWAYS perform a detailed pain assessment! Determine the TYPE of pain before implementing a treatment plan.

27 Pain Management Tips 101 All patients should be started on bowel program immediately on initiation. Change agent for severe side effects or inadequate control. Oral route is the most effective!
