Comfort Flashcards
(42 cards)
Transduction
Activated nociceptor converts energy produced by stimuli (mechanical, thermal, or chemical) into an action potential
Transmission
Pain signals move from the periphery to the level of the spinal cord and then to the brain
Perception
Conscious awareness of pain and perceiving it
Modulation
Last phase of the pain process; built-in mechanisms to slow or stop processing painful stimulus
Nociceptive pain
- Somatic pain: musculoskeletal tissues or body surface
- Visceral pain: internal organs ( heart attack=>shoulder pain
Neuropathic pain
- Difficult to assess
- Difficult to treat
Does not adhere to typical pain phases
-not detected by x-ray, CAT, or MRI
Abnormal processing of pain message
Pain perceived long after an injury healed
Evolves into a chronic condition
Breakthrough pain
Occurs in pts whose baseline persistent pain is usually mild to moderate and fairly well-concentrated
-transient
-moderate to severe pain
-avg. peak can be 3-5 minutes
-sometimes 30 min or longer
Can be predictable or unpredictable
Treatments of breakthrough pain
Lifestyle changes
Management of reversible causes
Modification of pathological processes
Nonpharmacologic management
Pharm management
Gate Theory of Pain
Suggests pain perception is influenced by โgateโ in spinal cord.
Things that OPEN the gate
Stress and tension - anxiety, worry, pain feel worse)
Mental factors - focusing all attention on the pain
Boredom and lack of activity
Things that CLOSE the gate
Relaxation and contentment - feeling happy and optimistic
Mental factors - involved - interest in life - focus elsewhere - not on pain
Activity/exercise
Counter stimulation - heat, massage, TENS, acupuncture
Distraction
Acute pain
Sudden
Mild to severe
<3 months or as long as it takes to heal
Usually can identify the cause
Pain decreases over time
Ex. Post-op, labor pain, trauma, pain from infection (UTI)
Acute pain behaviors
Increased HR, BP, RR
diaphoresis
Pallor
Anxiety
Agitation
Confusion
Urine retention
Chronic pain is persistent
Is not protective
Can be gradual or sudden (may start as acute)
Lasts longer than 3 months or past time of normal healing
Does NOT always have identifiable cause
Feels endless to pt
Can lead to depression or suicide
Can lead to opioid dependence or addiction
Chronic pain behaviors
Flat affect - try not to give an outward indication of pain
Decreased physical activity
Fatigue/hopelessness
Withdrawal from social interaction
Physiological changes for uncontrolled pain
-Cardia: tachycardia, HTN
- Pulmonary: hypoxia, decreased cough, Atelectasis
-GI: N/V, ileus
-Renal: Oliguria, urinary retention
-Musculoskeletal: spasms, joint stiffness
-CNS: fear, anxiety, fatigue
-Immune: impaired cellular immunity, wound healing
Aging Adult
NOT a normal process of aging
Does NOT feel pain less than others
Pain indicates injury
Clenched fist may = pain
Agitation may = hunger or cold
Pain assessment in Advanced dementia - PAINAD Scale
Principles of Pain Management
- Pt has right to pain management
- Pain is always subjective
- Physiological and behavioral signs of pain are NOT reliable
- Pain is unpleasant sensory and emotional experience
- Assessment approaches and tools - appropriate for age
- Pain can exist even if no physical cause can be found
- Pain experiences are different
- Pts w/ chronic pain may be more sensitive to pain and other stimuli
- Unrelieved pain has adverse consequences
Barriers to effective pain management
Fear of addiction
Fear of tolerance
Concern about side effects
Fear of injections
Desire to be good pt
Medication compliance - forgetting to take medication
Pain may indicate disease progression
Sense of fatalism or stoicism
Ineffective medication
Pain the 5th vital
PQRST
-Provocation- what makes it worse better
-Quality: sharp, burning, dull, stabbing
-Radiates: to another area
-Severity
-Timing/Treatment : when did it start?- how long does it last? - what has helped?
Comprehensive pain assessment
Location
Intensity
Quality
Onset/duration
Pattern
Contributing symptoms
Effects of pain
Comfort - function (pain) goal
Pain assessment tools
Brief pain inventory
Initial pain assessment
Universal pain assessment ๐๐ฌ
Numeric, simple, visual
Wong-Baker faces
FLACC - useful w/ children between 2 months - 7 years
Pain treatment
Follow principles of pain assessment
Every pt deserves adequate pain management
Base the treatment plan on the pts goals
Use both drug and non-drug therapies
When appropriate- use multimodal analgesia
Use an inter professional approach
Prevent or manage medication SE
Include pt and caregiver teaching
Non-opioid pharmacological interventions
Analgesics for MILD to MODERATE pain
Acetaminophen
NSAIDs : ibuprofen, aspirin
Alone - mild pain reliever
High doses - moderate pain relief
Combo w/ opioids - can reduce high levels of pain and actually reduce the opioid level required
