Canada is the 3rd largest opioid consumer globally. What implications are their?
- Are we using them responsibly
- Significant mortality due to resp depression
- Are there alternatives
____ live with chronic non cancer pain
25%
Gate control theory.
Transmission of nerve impulses modulated by a gating mechanism from afferent fibers to the spinal cord; when the gate is CLOSED there are no pain impulses and when OPEN small fibres facilitated pain transmission (ascend from spinal cord)
SUBSTANTIA GELATINOSA NEURONS in the dorsal hornin in the SC act as the GATE
Chemicals release in response to stimuli can influence opening and closing of the gate
In gate theory what is the gate?
SUBSTANTIA GELATINOSA NEURONS in the dorsal hornin in the SC act as the GATE
What type of fibres is the gate gating
afferent fibres that go to the spinal cord
What influences the opening and closing of the gate?
chemicals released in response to stimuli
How can rubbing help close the gate?
activates large diameter fibres and that closes the gate of neutrons in the dorsal horn
Chronic pain.
Pain that persists for more than 3 months or beyond the usual course.
- Persists beyond expected tissue healing time or d/t an underlying disease
- Persistent pain or pain that recurs at intervals for months or years
Chronic pain leads to…
suppression of immune function and disability
Elderly man comes into the clinic with persistent pain. VS are WNL, and he states 8/10 on pain scale. Drug seeking?
chronic pain causes the body to adapt thus VS are not an indicator of pain level (only in acute)
What are the consequenses of chronic pain?
FATIGUE(d/t pain, depression, decreased sleep), DEPRESSION (lack of control and social isolation), ANXIETY (can increase pain), SLEEP DISTURBANCES
Nociceptive pain.
due to tissue damage; free nerve endings in the skin respond to intense damaging stimuli
Somatic.
skeletal muscle fascia and tendons
Visceral.
deep bodily organs, GI, pancrease
Neuropathic pain.
d/t nerve damage or abnormal processing of sensory input
- peripheral or CNS injury (phantom limb pain)
- peripheral nerve endings (diabetic neuropothy)
- described as burning; can be short lived or lingering
What assessment should be done for ppl with chronic pain?
depression and chronic pain go hand in hand
- MSE to assess for depression
What are the multidimensional factors of chronic pain?
PHYSIOLOGICAL SENSORY BEHAVIOURAL AFFECTIVE SOCIOCULTURAL FAMILY/GENDER ROLES
Physiological aspect of pain.
PHYSIOLOGICAL- involve transduction, transmission, perception and modulation of pain
Sensory aspect of pain.
PQRSTU
Behavioural aspect of pain.
action to decrease intensity/indicate presence of pain (rubbing, grimacing, bending over)
Affective aspect of pain.
emotional component
Sociocultural aspect of pain.
SOCIOCULTURAL- pain response, perception, how much is tolerable; ways to express pain; pain relief methods
