Introduction
Odyn- is a prefix meaning pain. An unpleasant sensory & emotional experience associated with actual or potential tissue damage or described in terms of such damage.
3 hierarchichal levels of pain
- sensory-discriminatory component
- location, intensity, quality
- motivational-affective component
- cognitive-evaluative component
- thoughts concerning the cause & significance
Classification
- nociceptive pain
- trauma or burns
- infection or inflammation
- ischemia
- mechanical deformity
- distention
- arthropathies
- rheumatoid arthritis
- osteoarthritis
- gout
- post-traumatic arthropathies
- mechanical neck & back syndromes
- myalgia (i.e myofascial pain syndromes)
- non-articular inflammatory disorders (e.g. polymyalgia rheumatica)
- visceral pain
- pain of internal organs & viscera
- trauma or burns
- neuropathic pain
- peripheral nervous system
- postherpetic neuralgia
- trigeminal neuralgia
- painful diabetic polyneuropathy
- post-amputation (phantom limb) pain
- central nervous system
- post-stroke pain (central pain)
- myelopathic/radiculopathic pain
- sympathetic nervous system
- peripheral nervous system
- mixed or idiopathic pathophysiology
- chronic recurrent headaches
- vasculopathic pain syndromes (painful vasculitis)
- psychologically-based syndrome
- somatization disorders
- hysterical reaction
- negative emotions may increase itching & pain[9]
- acute pain: pain lasting < one month
- subacute pain: pain lasting from 1-3 months
- chronic pain: pain lasting > 3 months
Epidemiology
- in long-term care facilities pain correlates with
- fractures
- pressure ulcers
- falls in the elderly
- sleeping disorders
- cancer
- unstable health
- depression
- number of drugs
- female gender
- 49% of long-term care residents experience pain[16]
History
(pain characteristics)
- temporal
- acute, recurrent or chronic
- onset & duration
- course & daily variation, including breakthrough pain
- intensity (average, worst, least, "right now")
- topography (focal, multifocal, referred, superficial or deep)
- quality
- aching, throbbing, stabbing, burning
- familiar or unfamiliar pain
- exacerbating & relieving factors
- volitional or nonvolitional
- response to treatment[1]
Clinical manifestations
- facial expressions, grimmacing, tears, crying
- vocalizations
- moaning, groaning
- outbusrts
- explicit expressions of pain
- noisy breathing
- body language
- social features
- social withdrawal
- lability
- resistance to interventions
- aggression, combativeness
- loss of appetite, refusal of food
- change in sleep patterns
- confusion, irritability, delirium[12]
- nausea & constipation from opiate use
* observing behavioral manifestations of pain is the primary mode of pain assessment in patients with dementia[11]
Complications
Management
- ABCDE for pain assessment & management[4]
- Ask about pain regularly. Assess pain systematically.
- Believe the patient & family in their reports of pain & what relieves it
- Choose pain control options appropriate for the patient, family & setting
- Deliver interventions in a timely, logical & coordinated fashion
- Empower patients & their families. Enable them to control their course to the greatest possible extent
- principles
- individualize management
- despite ABCDE recommendations, GRS11 recommends obtaining a medical interpeter over using family to assess patient's pain concerns if patient not fluent in english[11]
- use simplest approach
- identify & treat source of pain
- recognize & treat emotional & cognitive components[6]
- pain is most often undertreated, not overtreated
- consider combined pharmacologic & non-pharmacologic therapy
- analgesia
- all analgesic regimens should include a nonopioid drug (NSAID, acetaminophen) unless contraindicated, even if pain is intense enough to require opiate
- <= 3 days of opiate therapy for severe pain generally adequate
- avoid > 1 week of opiate therapy for acute pain
- consider analgesic adjuvant
- anticipate adverse effects
- address patient concerns
- physical vs psychologic dependence
- avoid placebos
- individualize management
- elderly
- acetaminophen should be the initial drug treatment for persistent particularly musculoskeletal pain
- nonselective NSAIDs & COX-2 selective inhibitors may be considered 'with caution' for patients in whom other (safer) therapies have failed
- salsalate may be less nephrotoxic & have less anti-platelet activity than other NSAIDs[11] (evidence supporting the is sparse)[11]
- patients with fibromyalgia or neuropathic pain are candidates for adjuvant analgesics
- breakthrough pain should be anticipated with opioid use; use short-acting, immediate-release opioids
- in nursing home, residents age > 95 years, cognitively impaired or black or Asian race less likely to receive prescription analgesics[11]
- investigational
- cold analgesia can block pain signaling
