Title: Pain Management


1
Pain Management
2
Safety, Security and Comfort Needs of the Acutely
Ill Client
  • PAIN
  • The 5th Vital Sign

3
Definitions of Pain
  • Pain is whatever the experiencing person says it
    is, existing whenever he/she says it does. -Mc
    Caffery 1968
  • An unpleasant sensory and emotional experience
    associated with actual or potential tissue damage
    or described in terms of such damage. - Intl.
    Assoc. for the study of pain

4
  • Only 30 of cancer patients get adequate pain
    relief
  • 15-20 of Americans have acute pain
  • 25-30 of Americans have chronic pain
  • Leading cause disability for those lt 45 y/o

5
The Mechanisms of Pain
  • Transduction
  • Transmission
  • Perception
  • Modulation

6
The Mechanisms of Pain
  • Transduction-
  • Conversion of mechanical, thermal or chemical
    stimulus into a neuronal action.
  • Peripheral nerve sites- peripheral afferent
    nociceptor (PAN)
  • Action Potential causes movement of pain stimulus
    What causes it?
  • Nociceptive- Release of Chemicals
  • Neuropathic- Abnormal processing of stimuli by
    the nervous system

7
The Mechanisms of Pain
  • Transmission- movement of pain impulses from the
    site of transduction to the brain.
  • Transmission along the nociceptor fibers to the
    level of the spinal cord.
  • Dorsal horn processing.
  • Transmission to the thalamus and the cortex.

8
The Mechanisms of Pain
  • Perception- recognition of pain
  • However, there is no precise location where pain
    perception occurs.
  • Individualized
  • Imagery is a good pain-reduction therapy.
  • Subjective
  • Sensory Recognition that you have pain.
  • Affective Emotional responses to pain.
  • Behavioral How someone expresses or controls
    pain.
  • Cognitive Persons beliefs attitudes about
    pain.
  • Sociocultural Age, Gender, education level,
    culture and support systems.

9
The Mechanisms of Pain
  • Modulation- activation of descending pathways
    that either inhibit or facilitate effects on pain
    transmission.

10
Types of Pain
  • Nociceptive Pain
  • Normal processing of stimuli that damages or has
    the potential to damage, normal tissues if
    prolonged.
  • Different types of origins
  • Somatic Pain Arises from bone, joint, muscle,
    skin or connective tissue.
  • Visceral Pain Arises from visceral organs, such
    as pancreas or stomach.

11
Somatic Pain
  • Described as achy, stabbing, sharp
  • Examples
  • Bone pain, fractures
  • Muscle tears, sprains
  • Joint pain
  • Soft tissue injury

12
Visceral Pain
  • Diffuse and difficult to localize if d/t
    obstruction of hollow viscus
  • Sharp, aching when due to injury to other
    visceral structures such as
  • Pancreatitis
  • Kidney Stones
  • Menstrual Cramps
  • Bowel Obstruction

13
Neuropathic Pain
  • Multiple Pain Syndromes
  • Often difficult to treat.
  • Believed to be the abnormal firing of the
    peripheral or central nervous system.
  • Often described as burning, stinging, shooting,
    traveling, or electric-like.
  • Caused by phantom limb pain, complex regional
    limb pain complex regional pain syndromes,
    diabetic neuropathy, post-herpetic neuralgia, or
    trigeminal neuralgia

14
Acute VS. Chronic Pain
  • ACUTE
  • Sudden
  • Short Duration lt 3 months
  • Mild--gt Severe
  • Can identify specific cause.
  • Predictable prognosis
  • Can be single event or recurrent.
  • ? as healing progresses.
  • CHRONIC
  • Continues for more than one month after healing
    or an acute lesion, or
  • Recurs over a chronic period of time.
  • Pathophysiology may be unclear.
  • Unpredictable prognosis
  • Is associated with a lesion that is not expected
    to heal.
  • Chronic cancer pain or chronic non-malignant pain.

15
Sources of Pain
Visceral Pain Muscloskeletal Neuropathic
Generalized pain related to visceral stretch. Described as sharp ache. Usually localized. Described as dull ache. Irritation of verve. Described as burning, sharp, shooting.
Classic referral pain. PT, massage, heat cold helpful. PT helpful.
Responds best to opioids. Some response w/opioids. Adjuvants helpful. NSAIDs/Steroids, muscle relaxers Opioids usually not helpful- only dull the pain. Adjuvants helpful Tricyclic AD, anti-convulsants.
16
Acute VS. Chronic Pain Cont
  • May be associated with sympathetic hyperactivity
    and anxiety.
  • Usually resolves
  • Treated with short-acting drugs.
  • May be associated with depressed mood, sleep
    disturbance and disability.
  • Treated with long-acting drugs and adjuvant
    therapy.

17
Pharmacology of Pain Management
  • Individualized- Based on the patients medical
    and pain histories.
  • Multi-modal- Targets multiple sites of action.
  • Optimize effects
  • Minimize adverse effects

18
Pharmacology of Pain Management Cont
  • Routes of Administration
  • Oral
  • Sublingual
  • Transmucosal
  • Transdermal
  • Parenteral IV, IM, SQ
  • Nebulized
  • Rectal
  • Epidural/Intrathecal (Morphine, Fentanyl)

19
Pharmacology of Pain Management Cont
  • How do Opioids work?
  • Opioids act on the opioid receptor sites and
    activate endogenous pain suppression systems in
    the CNS (Mu receptor sites).
  • Receptor sites are found in
  • Dorsal horn of the spinal cord
  • Pituitary gland
  • GI tract
  • Endogenous exogenous opioids control pain by
    locking onto opioid receptor sites and blocking
    the release of neurotransmitters.

20
Pharmacology of Pain Management Cont
  • How NSAIDs and Acetaminophen work?
  • Non-opioids include NSAIDs, Tylenol and Aspirin.
  • They act on the peripheral nerve endings at the
    site of injury altering the prostaglandin system.
  • NSAIDs have an anti-inflammatory effect.
  • Acetaminophen does NOT have an anti-inflammatory
    effect. Like ASA, it has analgesic and
    antipyretic effects.
  • Side effects
  • NSAIDs GI irritation, possible nephrotoxicity.
  • Acetaminophen can cause hepatoxicity.
  • Limit 4 grams/24hr

21
Pharmacology of Pain Management Cont
  • Short Acting Pain Medications
  • Provide analgesia within 30 min.
  • Diluadid, Morphine
  • Actiq-fastest acting oral medication- onset
    within 5 min. (transmucosal)
  • oral solution/Roxanol-elixir form of morphine.
  • Helpful for pts. with difficulty swallowing.
  • Titratable.
  • Oxycodone/ tablets- used for short-term therapy
    or supplemental dosing (breakthrough pain).
  • Compounds Tylenol 3, Hydrocodone-
    Lortab/Vicodin, Oxycodone- Percocet.
  • Propoxyphene- Darvon/Darvocet

22
Pharmacology of Pain Management Cont
  • Long Acting Opioids
  • Usually used for long-term pain.
  • For patients requiring frequent breakthrough
    dosed of opioids.
  • More predictable serum levels
  • Easier to use lower dosing intervals, improved
    compliance

23
Pharmacology of Pain Management Cont
  • Meperidine
  • Has a metabolite that is 2x as potent as a
    convulsant and 1/2 as potent as an analgesic.
  • Breaks down to nomeperidine which has an active
    metabolite that accumulates w/multiple dosing.
  • Hepatic or renal failure and increases toxicity.
  • Accumulation of active metabolites can produce
    irritability, tremors, muscle twitching, jerking,
    agitation or seizures.

24
Common Nonopiod Analgesics
Drug Adult dose Considerations
Acetaminophen (Tylenol) 650-975 mg q 4 hr Used for headaches, osteoarthritis, lacks peripheral anti-inflammatory activity of NSAIDs.
Aspirin 650-975 mg q 4 hr Used for headaches, osteoarthritis, general pain, antipyretic, inhibits platelet aggregation.
Ibuprofen 400 mg q 4-6 hr Antipyretic, Used for osteoarthritis, available as liquid
Indomethacin (Indocin) 150-200 mg/day Used for gout, antinflammatory, antirheumatic
Naproxen (Naprosyn) 500 mg initial dose, then 250 mg q 6-8 Used for gout, headaches, smooth muscle contraction, available in liquid
25
Adjuvant Analgesics
  • Nontraditional analgesics, most approved for
    other indications.
  • Multipurpose drugs
  • For muscloskeletal pain
  • Muscle relaxants (Baclofen, Zanaflex)
  • For neuropathic pain
  • Antidepressants- (Pamelor, Cymbalta)
  • Anticonvulsants- Topamax, Gabapentin, Lyrica
  • Approved for post-herpatic neuralgia, diabetic
    neuropathy.

26

  • It is what the client says it is.
  • Location- Where?
  • Description- How does it feel?
  • Objective Assessment
  • Intensity- Rating scale
  • 0 ? pain
  • 10 worst possible pain
  • Duration- When did it start, How long does it
    last, Is it continuous or intermittent?

28
Nursing Pain Assessment
  • Objective Assessment cont.
  • Alleviating contributing factors
  • What makes the pain better or worse?
  • Associative factors
  • Nausea
  • Vomiting
  • Altered LOC
  • Impact of pain
  • How does it affect their lives?
  • Past pain experiences
  • Recent surgery, chemical use or abuse

29

31
Planning, Goal Setting Interventions
  • Alleviate Pain!!!!!!!! Improve Comfort.
  • By when?
  • From what to what? 0-10
  • Interventions
  • Pain Medication!!
  • Adjuvants
  • Positioning
  • Responsibility
  • Involve Family
  • Humor
  • Preventing Complications!!!!!!

32
Important Definitions
  • Tolerance- an adaptive process due to exposure to
    a drug over time. Results in a decrease response
    to a drugs effect over time.
  • Physical Dependence- a physiologic phenomenon
    that should be expected in persons with
    persistent use of certain drugs. Patients will
    experience a withdrawal syndrome if a drug is
    abruptly stopped, there is a rapid dose
    reduction, or if the person is given a reversal
    agent. Withdrawal can be prevented by gradual
    taper
  • Reversal Agents
  • Narcan- Opioids
  • Romazacon- Benzodiazapam

33
Important Definitions Cont.
  • Pseudoaddiction- This is not true addiction and
    is created by under treatment of pain. A term
    used to describe behaviors seen in persons who
    fear or who are experiencing uncontrolled pain
    and want to obtain medication for adequate pain
    relief. The clock-watching, requesting extra
    opioids, and demanding behaviors are eliminated
    when the pain is relieved.

34
Important Definitions Cont.
  • Addiction- A primary, chronic, neurobiological
    disease with genetic, psychosocial and
    environmental factors. Characteristics include
  • Impaired control over drug use
  • Compulsive use
  • Continued use despite harm
  • The need to use an opioid for effects other than
    for pain relief and craving.

35
Important Definitions Cont.
  • Breakthrough Pain-
  • Transitory increase in pain to greater than
    moderate intensity which occurs on top of the
    baseline pain.
  • Distinguished from
  • Continuous or uncontrolled pain
  • Acute episodic pain.

36
Pain Gerontologic Considerations
  • 45-80 of older adults have chronic pain.
  • Inadequately assessed and treated.
  • Common types osteoarthritis, low back pain and
    previous fracture sites.
  • Chronic pain can lead to
  • Depression
  • Sleep disturbances
  • Decreased mobility
  • Increased health care utilization
  • Physical social role dysfunction

37
Pain Gerontologic Considerations Cont.
  • Believe that pain is normal.
  • Nothing can be done.
  • Labeled as burdensome or bad pt.
  • Fear of drugs.
  • Pain tolerance DECREASES with age.
  • Cognitive, sensory-perceptual , and motor
    problems may impair ability to communicate or
    process information.
  • Post-stroke aphasia, paraplegia, dementia,
    delirium, vision, hearing impairments

38
Fibromyalgia Syndrome
  • Widespread, nonarticular muscloskeletal pain and
    fatigue with multiple tender points.
  • Non-degenerative, non-progressive
    non-inflammatory.
  • Effects over 6 million Americans
  • More women than men 20-55 years old.
  • Possible causes
  • Abnormal levels of serotonin, norepi and other
    neurotransmitters.
  • Hyperfunctioning of the hypothalamic-pituitary-adr
    enal axis (HPA).

39
Fibromyalgia Syndrome Treatment
  • Supportive management
  • NSAIDs
  • Tricyclic Anti-depressants or SSRIs
  • Well balanced diet
  • Behavioral Therapy
  • Financial concerns and support
  • Carefully graduated exercise program.

40
Chronic Fatigue Syndrome

    and a variety of associated complaints.
  • 3x more likely in women onset 25-45 years old.
  • Etiology unknown
  • Ideas
  • Viral infection usually precipitates the
    syndrome.
  • Abnormal immune function.
  • Alterations in the CNS.
  • Depression usually occurs in patients.

Cancer End-of-Life Care
42
Nursing Care of the Client with Cancer
  • Cancer Background
  • A. Definition

  • 1. Normal Cell Growth includes two events
  • a. Replication of cellular DNA
  • b. Mitosis (cell division)

47
Nursing Care of the Client with Cancer
  • 2. Cell cycle is under control of cyclins, and
    suppresor gene products which control process by
    working with enzymes
  • cyclins promote cell division
  • suppresor gene products limit cell
    division
  • 3. Forms the basis of how some chemotherapeutic
    agents work against cancers

48
Nursing Care of the Client with Cancer
  • Theories of Carcinogenesis (what causes cancer to
    occur)
  • 1. Cellular Mutation
  • a. Cells begin to mutate (change the DNA to
    unnatural cell reproduction)
  • 2. Oncogenes/Tumor Suppressor Genes Abnormalities
  • a. Oncogenes are genes that promote cell
    proliferation and can trigger cancer
  • b. Tumor suppressor genes normally suppress
    oncogenes but are damaged
  • 3. Exposure to Known Carcinogens
  • a. Act by directly altering the cellular DNA
    (genotoxic)
  • b. Act by affecting the immune system
    (promotional)

49
Nursing Care of the Client with Cancer
  • 4. Viruses
  • viruses break the DNA chain and mutates the
    normal cells DNA
  • Epstein-Barr virus
  • Human papilloma virus
  • Hepatitis virus
  • 5. Drugs and Hormones
  • a. Sex hormones often affect cancers of the
    reproductive systems (estrogen in some breast
    cancers testosterone in prostate cancer)
  • b. Glucocorticoids and steroids alter immune
    system

50
  • 6. Chemical Agents
  • a. Industrial and chemical
  • b. Can initiate and promote cancer

  • Ionizing radiation found in x-rays, radium,
    uranium
  • UV radiation
  • Sun, tanning beds
  • Immune function
  • Protects the body from cancerous cells
  • Increased rate of cancer in immunocompromised pts

51
Nursing Care of the Client with Cancer
  • Neoplasms also called tumors (mass of new tissue
    that grows independently of surrounding organs
  • 1. Types of neoplasms
  • a. Benign
  • 1. Localized growths respond to bodys
    homeostatic controls
  • 2. Encapsulated
  • 3. Stop growing when they meet a boundary of
    another tissue
  • 4. Can be destructive
  • b. Malignant
  • 1. Have aggressive growth, rapid cell division
    outside the normal cell cycle
  • 2. Not under bodys homeostatic controls
  • 3. Cut through surrounding tissues causing
    bleeding, inflammation, necrosis (death) of tissue

52
Nursing Care of the Client with Cancer
  • Malignant tumors can metastasize
  • a. Tumor cells travel through blood or lymph
    circulation to other body areas and invade
    tissues and organs there.
  • 1. Primary tumor the original site of the
    malignancy
  • 2. Secondary tumor (sites) areas where
    malignancy has spread i.e. metastasis (metastatic
    tumor)
  • 3. Common sites of metastasis are lymph nodes,
    liver, lungs, bones, brain
  • 4. 50 60 of tumors have metastasized by time
    primary tumor identified
  • b. Cancerous cells must avoid detection by immune
    system

53
Nursing Care of the Client with Cancer
  • C. Malignant neoplasms can recur after surgical
    removal of primary and secondary tumors and other
    treatments
  • D. Malignant neoplasms vary in differentiation.
  • a. Highly differentiated are more like the
    originating tissue
  • b. Undifferentiated neoplasms consist of immature
    cells with no resemblance to parent tissue and
    have no useful function
  • E. Malignant cells progress in deviation with
    each generation and do no stop growing and die,
    as do normal cells
  • F. Malignant cells are irreversible, i.e. do not
    revert to normal
  • G. Malignant cells promote their own survival by
    hormone production, cause vascular permeability
    angiogenesis divert nutrition from host cells

54
The steps of metastasis
55

    care if clients cancer is not responding to
    treatment

63
Nursing Care of the Client with Cancer
  • Treatment Options (depend on type of cancer)
    alone or with combination
  • A. Chemotherapy
  • 1. Effects are systemic and kills the metastatic
    cells
  • 2. Often combinations of drugs in specific
    protocols over varying time periods
  • Much more effective then a single agent
  • Consider the timing of the nadir of each drug
  • The time when the bone marrow activity and WBC
    counts are at their lowest levels after chemo
  • Different times for different drugs

64
  • 3. Cell-kill hypothesis with each cell cycle a
    percentage of cancerous cells are killed but some
    remain repeating chemo kills more cells until
    those left can be handled by bodys immune system

65
Nursing Care of the Client with Cancer
  • B. Classes of Chemotherapy Drugs
  • 1. Alkylating agents
  • 1. Action create defects in tumor DNA
  • 2. Examples Nitrogen Mustard, Cisplatin
  • 2. Antimetabolites
  • 1. Action similar to metabolites needed for
    vital cell processes
  • Counterfeit metabolites interfere with cell
    division
  • 2. Examples Methotrexate 5 fluorouracil
  • 3. Toxic Effects nausea, vomiting, stomatitis,
    diarrhea, alopecia, leukopenia
  • 3. Antitumor Antibiotics

  • 1. Occurs with rapid necrosis of tumor cells with
    chemotherapy
  • When tumor cells die they release potassium and
    purines
  • Potassium (norm 3.5-5.5) elevation causes cardiac
    arrhthymias, muscle weakness, twitching, cramps
  • Purines convert to uric acid which causes renal
    failure, flank pain, gout when elevated above 10
    mg/dl
  • Hyperphosphatemia with secondary to hypocalcemia
    causes heart block, HTN, renal failure

99
