6.1 Flashcards
acupuncture
very small needles are inserted on one of the 356 to 700 acupoints that are located on meridians throughout the body to release the flow of qi
acute pain
similar to fight or flight reactions- increased heart rate increased blood pressure increased respiratory rate dilated pupils sweating
addiction
occurs over a long time- not as a result of one hospital stay or treatment for one episode of acute pain.
analgesic
pain relief medication
breakthrough pain
transient, moderate to severe pain that occurs above the pain treated by depression
Chronic Pain
Prolonged pain usually lasting beyond six months. Is often accomplished by depression
Endorphins
Morphine like substances found in the central nervous system that alter the perception of pain
Epidural Analgesia
Infusion of pain-relieving medication through a catheter placed into the epidural space surrounding the spinal cord. The administration may be intermittent or constant and is monitored by the nurse. Side effects to me monitored are depression of vital signs and of respiratory muscles.
Pan Pathway
Afferent nerve- spinal cord-cerebral cortex-spinal cord-efferent nerve.
On-Q-Pain Pump
Balloon type pump billed with a local anesthetic directly into an intra operative side for post operative pain relief.
Pain Threshold
Point at which increasing intensity of stimuli is felt as painful, person becomes aware of the pain sensation.
Patient-Controlled Analgesic (PCA)
Self-Administration of a predetermined does of analgesia by the client (usually by IV through a machine). Allows for a constant, steady, safe serum level of the analgesic.
Phantom Limb Pain
Pain referred to an amputated leg where receptors and nerves are clearly absent. d
Placebo
Inactive substitute given instead of a medication. Relief of pain by a placebo is in no way synonymous with malingering; the client has pain. Pain relief by a placebo is neither consistent nor predictable. The psychic response is influenced as well by the “placebo”effect of a trusting relationship with a nurse, physician or other persons, distractions, suggestion, environmental factors such as privacy and noise.
Recent studies suggest the effectiveness of placebo is related to the release of endorphins
Potentiators
A group of medications used to intensify the action of narcotic agents, thus increasing the degree and duration of analgesia. Phenergan, Atarax, and Valium are examples of potentiators.
Referred Pain
Pain in an area removed from that in which stimulation has its origins
Stimulating Agents
Agents that stimulate pain receptors; mechanical, thermal, electrical and chemical.
Tanscutaneous Electrical Nerve Stimulation (TENS)
Battery operated unit with electrodes which produce tingling in are of pain. Decreased both acute and chronic pain by stimulating the non pain (non-nociceptors) in the area. If consistent with the gate control theory of pain.
