Exam 3 (pain management) Flashcards
- converts energy produced by thermal, chemical, or mechanical stimuli into electrical energy
Transduction
- a sensory peripheral pain nerve fiber
Nociceptor
- generated from the breakdown of cell membranes; thought to increase sensitivity to pain
Prostaglandins
- produced by mast cells causing capillary dilation and increased capillary permeability
Histamine
- released from the brainstem and dorsal horn to inhibit pain stimulation
Serotonin
- natural morphine like substances in the brain released as a response to pain
Neuromodulators (inhibitory)
_____ is protective and usually has a identifiable cause, is short duration, has limited tissue damage and emotional response
Acute pain
________ serves no purpose but and an emotional impact on one’s life; examples such as arthritis, low back pain, headache etc
Chronic/persistent non cancer pain
_____ pain comes from one, joint, muscle, or tissue
Somatic
_____ pain arises from visceral organs such as the GI tract and pancreas
Visceral
- normal stimulation of peripheral nerve endings such as somatic and visceral pain
Nociceptive pain
- abnormal processing of sensory input such as phantom pains or nerve root compression
Neuropathic pain
- chronic pain in the absence of a cause or pain that is excessive for the extent of a condition
Idiopathic pain
- pain resulting from stimulation of the skin
Superficial or cutaneous
- pain from internal organs
Deep or visceral
- pain in unaffected areas due to lack of nociceptors
Referred
- sensation of pain extending from initial injury site to another body part
Radiating
-drugs like aspirin, ibuprofen, and naproxen that relieve mild pain such as headache or muscle strain
NSAID (non-steroidal anti-inflammatory drug)
- acetaminophen (tylenol) and NSAIDs
Non Opioid
- traditionally called narcotics
Opioids
- co-analgesics that enhance the analgesic properties
Adjuvants
- combines drugs with two different mechanisms so that dosage and side effects can be minimised and pain control can be optimized
Multimodal analgesia
- drug delivery system that allows for a patient to administer their drugs; benefits are that the patient gains control over pain relief
Patient controlled analgesia (PCA)
- the local infiltration of an anesthetic medication to include loss of sensation in a body part
Local analgesia
