PAIN Flashcards
Defined as
“unpleasant sensory, emotional experience with actual or potential tissue damage”
PAIN
Pain is a __&___ experience
Personal and subjective experience
WHO is the most reliable indicator of pain and essential component of pain assessment
PATIENT.
PAIN AFFECTS EVERY ONE
…NO MATTER THE
Age
Sex
Race
Gender
Socioeconomic class
Affects every system
There are 3 types of pain.
Name them?
- Acute pain
- chronic pain
- breakthrough pain.
Which type of PAIN am I?
*Differs from chronic by duration
*Result of tissue damage; surgery; trauma
*SHORT duration and resolved with normal healing
ACUTE PAIN
WHAT type of PAIN am I?
*Can be time limited OR last a lifetime
*SUCH AS:
- Cancer
- Noncancer: peripheral neuropathy, back pain, osteoarthritis
CHRONIC PAIN
WHICH TYPE OF PAIN AM I?
chronic pain with acute exacerbations
Breakthrough pain
TWO types of CLASSIFICATION of Pain are:
- Nociceptive (physiologic) pain
- Neuropathic (pathophysiologic) pain
Example of Nociceptive (physiologic) pain
Tissue injury
Example of Neuropathic (nerve) pain
Damage to the peripheral or central nervous system
There are 4 Processes of Nociceptive (physical) Pain.
What are they?
- Transduction
- Transmission
- Perception
- Modulation
Which Nociception Process am I?
PROCESS by which noxious stimuli, such as a surgical incision or burn, activate primary afferent neurons called nociceptors, located throughout the body in the skin, subcutaneous tissue, and visceral (organ), and somatic (musculoskeletal structures).
TRANSDUCTION
Which Nociception Process am I?
- Transduction along the A-delta fibers (rapid) and C fibers (slower impulse)
- The A-delta fibers detect thermal and mechanical injury responsible for rapid reflex withdrawal.
- C fibers respond to thermal, mechanical, and chemical stimuli.
Transmission
Which Nociception Process am I?
- A process of the neural activity associated with transmission of noxious stimuli.
*This requires higher brain structures.
Perception
Which Nociception Process am I?
- Occurs at every level from the periphery to the cortex and involves many different neurochemicals.
Modulation
DEFINE:
caused by either a lesion or a disease.
Neuropathic Pain
Neuropathic Pain:
Results from damage or dysfunction of the
peripheral OR central nervous system
Neuropathic Pain May occur in the absence of tissue ___&____.
damage and inflammation
NEUROPATHIC PAIN includes both mechanisms.
1.
2.
- Peripheral mechanisms
- Central mechanisms
Components of Pain ASSESSMENT include
- Self-report
- Location
- Intensity
- Quality
- Onset and duration
- Aggravating and relieving factors
- Effects on function and quality of life
What is the NURSES FUNCTIONAL GOAL for patient with pain?
Comfort
What is the MOST COMMON Pain scale used?
The Wong-Baker FACES Pain Scale
What scales are used to Assess the INTENSITY of pain?
5 TOTAL
- Numeric Rating Scale (NRS)
- Wong–Baker FACES Pain Rating Scale
- Faces Pain Scale—Revised (FPS-R)
- Verbal descriptor scale (VDS)
- Visual Analog Scale (VAS)
What scale is used to Assess Pain for NONVERBAL patients?
The Hierarchy of Pain Measures
What scale is used to Assess Pain for YOUNG CHILDREN?
FLACC
F- facial expression
L- Leg movmnt
A- Activity
C- Crying
C- Consolability
*Assigned scores from 0-10
What scale is used to Assess Pain for patients with ADVANCED DEMENTIA?
PAINAD
(Pain Assessment In Advanced Dementia)
What scale is used to Assess Pain for patients in CRITICAL CARE units?
CPOT
(Critical Care Pain Observation Tool)
*Indicates whether or not they may be intubated.
Gerontologic (older adults) CONSIDERATIONS while administration of Analgesic Agents
- Older Adults often live with chronic pain
- Physiologic changes and comorbidities make pain management more complicated
- Older adults are often sensitive to the effects of analgesic agents
- Analgesic agents should be initiated with LOW doses and titration should proceed slowly with assessment of patients response
How to Manage Pain?
- Effective and safe analgesia: to control pain without depressing breathing. Always count Respiratory Rate before administration of opioids. Normal Resp. rate adult: 12 to 20 b/min. Watch for Bradypnea (respiratory rate below 12) when administering opioids, DRUG OVERDOSE is the MAIN cause of Bradypnea.
- Optimal relief: so that the patient can move without extreme pain
- Comfort function goal
- Responsibility of all members of the health care team
- Pharmacologic: multimodal
- Routes and dosing: take into consideration of the type of patient and age level and rate of metabolizing drug. Every patient is different. No one size fits all.
- Patient-controlled analgesia (PCA): *When setting up a PCA Pump for a patient make sure that the doctors orders includes a Dose Limit *
Physiologic Basis for Pain Relief- Pharmacologic Interventions
Opioid analgesics act on the_______ to INHIBIT activity of ascending nociceptive pathways
CNS
Opioid analgesic agents exert their effects by interacting with the body’s opioid receptor sites located throughout the body, including in the peripheral tissues, GI system, and CNS
The Opioid analgesics that are designated as FIRST LINE are
1.
2.
3.
4.
- morphine
- fentanyl
- hydromorphone (Dilaudid)
- oxycodone.
Common to see morphine, fentanyl and hydromorphone.
Hydromorphone (Dilaudid) is 2 to 8 times stronger than_______, also has a rapid onset.
morphine
The antagonists for opioid overdose and reverse adverse effects is called
NALOXONE
Adult dose IV o,4-2mg, may repeat q2-3 minutes up to 10mg if necessary
Physiologic Basis for Pain Relief- Pharmacologic Interventions
______ decrease pain by inhibiting Cyclo-oxygenase
(enzyme involved in production of prostaglandin)
NSAIDs
Physiologic Basis for Pain Relief- Pharmacologic Interventions
Local anesthetics block ________ when applied to nerve fibers
nerve conduction
NAME THE TWO ANALGESIC AGENTS
- NONOPIOID
- OPIOID
EXAMPLES OF NONOPIOID ANALGESIC AGENTS
- Acetaminophen (Tylenol)
- NSAIDs: ibuprofen, naproxen, celecoxib
