A

Superficial or Cutaneous ( Classification of Pain By Location)

77
Q

Pain resulting from stimulation of internal organs
Pain is diffuse and radiates in several directions. Duration varies, but it usually lasts longer than superficial pain. Pain is sharp, dull, or unique to organ involved.
ex Crushing sensation (e.g., angina pectoris); burning sensation (e.g., gastric ulcer)

A

Deep or Visceral (Classification of Pain By Location)

78
Q

Common in visceral pain because many organs themselves have no pain receptors (The entrance of sensory neurons from affected organ into same spinal cord segment as neurons from areas where individual feels pain causes perception of pain in unaffected areas.)

Q

A

Relaxation techniques

94
Q

transcutaneous electrical nerve stimulation (TENS) may reduce pain perception. One suggestion is that it causes release of endorphins, thus blocking the transmission of painful stimuli. The gate-control theory suggests that cutaneous stimulation activates larger, faster-transmitting A-beta sensory nerve fibers. This closes the gate, thus decreasing pain transmission through small-diameter C fibers

Q

works both peripherally and centrally: centrally it acts by activating sites in the spinal cord and brainstem that use opioid and serotonin receptors; peripherally neuroreceptors at the site of the TENS application produce analgesia

2) opioids (traditionally called narcotics);
(3) adjuvants or co-analgesics, a variety of medications that enhance analgesics or have analgesic properties

A

three types of analgesics:

101
Q

. Acetaminophen (Tylenol), considered one of the most tolerated and safest analgesics available, is available in a variety of over-the-counter (OTC) oral medications (e.g., cold and flu remedies) or rectal forms and in an intravenous (IV) preparation (Ofirmev)
-direct effect on the central nervous system by selectively inhibiting cyclooxygenase (enzyme)

A

Nonopioids

102
Q

has analgesic and antipyretic (no fever)

  • maximum 24-hour dose is 4 g like aspirin
  • combined with opioids (e.g., oxycodone, hydrocodone, tramadol) because it reduces the dose of opioid needed to achieve successful pain control.
  • cause hepatotoxicity; treat w/ acetylcysteine
A

Acetaminophen ((APAP)

325 mg/tablet

103
Q

such as aspirin, ibuprofen, and naproxen relieve mild-to-moderate acute intermittent pain such as that from headache or muscle strain.

A

Nonselective NSAIDs

104
Q

Treatment of mild-to-moderate postoperative pain begins with an NSAID unless contraindicated

  • inhibiting cyclooxygenase (COX), the enzyme that synthesizes prostaglandins
  • drugs inhibit cellular responses to inflammation
  • act on peripheral nerve receptors to reduce transmission of pain stimuli and inflammation
  • asthma or an allergy to aspirin are also allergic to NSAIDs
A

NSAID

105
Q

depress the central nervous system, & interfere with bowel or bladder function

A

opioids

106
Q

increase gastrointestinal irritation because COX normally synthesizes the prostaglandins that protect gastric mucosa. may reduce renal blood flow since COX causes vasodilation to maintain renal blood flow.
- use in the older patient is not recommended because it is associated with more frequent adverse effects (gastrointestinal bleeding as well as renal insufficiency)

Co-analgesics or adjuvants are drugs originally developed to treat conditions other than pain but that also have analgesic properties.

bisphosphonates and calcitonin(Adjuvants.)

121
Q

is a drug delivery system that allows patients to self-administer opioids (usually morphine, hydromorphone, or fentanyl) with minimal risk of overdose.
- not recommended for opioid-naïve patients following surgery because of the possibility for respiratory depression.

A

patient-controlled analgesia (PCA)

122
Q

include prescription and OTC creams, gels, sprays, liquids, patches, or rubs applied on the skin over painful muscles or joints and for peripheral neuropathy

A

Topical analgesics

123

-work when placed away 4m pain site

A

analgesic transdermal medications

124
Q

is a topical analgesic effective for cutaneous neuropathic pain such as postherpetic neuralgia in adults. Place three patches, cut to size, on and around the pain site using a 12-hour on, 12-hour off schedule

  • ELA-Max/LMX and eutectic mixture of local anesthetics (EMLA) are available for children
  • ELMA- thick cream to the skin 30 to 60 minutes before minor procedures
A

Lidoderm patch

125
Q

Do not place topical or transdermal analgesics on wounds, damaged skin, or the face. Pruritus or burning of the skin or a localized rash is common after

A

topical applications

126
Q

is the local infiltration of an anesthetic medication to induce loss of sensation to a body part. Health care providers often use local anesthesia during brief surgical procedures

A

Local anesthesia

127
Q

is the injection or infusion of local anesthetics to block a group of sensory nerve fibers

A

Regional anesthesia

128
Q

Smaller sensory nerve fibers are more sensitive to local anesthetics than are large motor fibers. As a result, the patient loses sensation before losing motor function; conversely, motor activity returns before sensation.

A

Regional anesthesia

129
Q

is the use of perineural injections and infusions of local anesthetic agents to relieve pain.

regional anesthesia

Q

be used to monitor for unintended patient sedation

  • highest risk for oversedation and respiratory distress (OSRD) during the first 24 hours of PCA administration
  • monitor first 1-2 hrs within 24 hrs
  • oversedation leads Resp depression
