Q

describe the modulation of pain:

A

once the pain perceives pain, there is a release of inhibitory neurotransmitters such as: endorphins (endogenous opioids), serotonin, norepinephrine, and gamma-aminobutyric acid (GABA), that hinder the transmission of pain and help produce an analgesic effect

  • inhibits pain impulse and serves as a protective reflex

Deliver - deliver interventions in a timely, logical, and coordinated fashion

Empower - enable them to control their course to the greatest extent possible.

45
Q

why is pain assessment not simply a number?

A

relying solely on a number fails to capture the multidimensionality of pain and may be unsafe

because of the first-pass effect of medication metabolized in the liver

65
Q

Describe co-analgesics/adjuvants drugs

A

co-analgesics and adjuvants drugs are used to treat other conditions, but they also have analgesic qualities (tricyclic antidepressants and
anticonvulsants).

66
Q

Follow these guidelines from the American Society for Pain Management Nurses:

A

1) Avoid administration of partial doses at more frequent intervals so as to not under dose a patient with small, frequent, ineffective doses from within a range.

2) Avoid making a patient wait a full time interval after giving a partial dose within the allowed range.

3) Wait until peak effect of the first dose has been reached before giving a subsequent dose.

67
Q

what is PCA?

A

Patient controlled analgesia. Allows patients to control when they take their PRN medications including: analgesics, antiemetics, and anxiolytics

68
Q

what form of administration is patient controlled analgesia?

A

1) IV
2) SUBQ
3) oral (rare)

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

77
Q

what is perineural local anesthetic infusion?

A

peri-neural: Next to nerve

a surgeon places the tip of an un-sutured catheter near a nerve or group of nerve fibers and the catheter exits from the surgical wound (common after surgery)

78
Q

A

1) pruritus (burning of the skin)
2) localized rash

79
Q

application of a topical anesthetic to a vascular mucous membrane increases the chance of what?

A

increases the chance of systemic effects like a change in HR

80
Q

The use of local anesthetics on peripheral nerves and epidural infusions may have what effect?

A

block motor nerves in addition to sensory nerves leading to temporary paralysis of affected body part

81
Q

what does epidural analgesia treat(4)?

A

effectively treats:
1) acute postoperative pain
2) rib fracture pain
3) labor and delivery pain
4) chronic cancer pain

reducing a patient’s overall opioid requirement which minimizes adverse effects

82
Q

is epidural analgesia a long-term or a short-term therapy?

A

can be either or depending on a patient’s condition and life expectancy

83
Q

One of the concerns related to the use of peripheral and epidural anesthetic techniques?

A

because the epidural space is a highly vascular area, patients with epidural catheters are at risk for developing epidural hematomas which can lead to ischemia of the spinal cord. If unaddressed, serious neurological complications can occur.

84
Q

why do you NOT administer supplemental doses of opioids or sedative/hypnotics to someone receiving epidural analgesia?

A

risk of possible additive central nervous system adverse effects

85
Q

With a patient receiving epidural analgesia, anticoagulants and antiplatelets…

A

should not be administered to a until safe use can be verified with a pain specialist because of increased risk of bleeding and hematoma formation

86
Q

What interventions are available when severe pain persists despite medical treatment?

Invasive interventions:

A

available invasive interventions include: intrathecal implantable pumps or injections, spinal cord and
deep brain stimulation, neuroablative procedures (cordotomy, rhizotomy), trigger point injections, cryoablation, and intraspinal medications.

87
Q

when patients receive epidural analgesia, how often do you monitor them?

A

initially assessments every 15 minutes. Once stabilized, monitoring occurs about every hour for 12-24 hours.

88
Q

when severe pain persists despite medical treatment, what are some more invasive treatments available(6)?

A

1) intrathecal implantable pumps or injections
2) spinal cord and deep brain stimulation
3) neuroblative procedures

5) cryoablation
6) intraspinal meds

89
Q

Describe the prevalence of chronic or acute cancer pain.

A

chronic or acute cancer pain ranges from 64% in patients with metastatic, advanced or terminal phases of the disease, 59% in patients on anticancer treatment, and 33%
in patients after curative treatment.

90
Q

what is breakthrough cancer pain (BTCP)?

A

BTCP - a transient worsening of pain that occurs either spontaneously or in relation to a specific predictable or unpredictable trigger,despite relatively stable and adequately controlled background pain.

91
Q

According to the American Pain Society, what is the primary goal in treating chronic noncancer pain with opioids?

A

he primary goal is to increase patients’ level of function rather than just to provide pain relief

92

A

D

93
Q

what is the analgesic ladder?

A

a three step approach to manage cancer pain that begins with NSAIDs and/or adjuvants and progresses to opioids

94
Q

what is the bidirectional approach to the analgesic ladder?

A
  • the original analgesic ladder progresses up the steps starting from NSAIDs
  • the bidirectional approach would include a step down approach for patients with intense acute pain, uncontrolled cancer pain, and breakthrough pain
95
Q

what can be considered the 4th step of the 3-step analgesic ladder?

A

rectal

98
Q

define physical dependence on a drug

A

a state of adaptation that is manifested by a drug class-specific withdrawal syndrome produced by an abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist

99
Q

define addiction

A

a primary, chronic, neurobiological disease with genetic, psychological, and environmental factors influencing its development and manifestations

100
Q

define drug tolerance

A

a state of adaptation in which exposure to a drug induces changes that result in diminution of one or more effects of the drug over time

101
Q

what are barriers to effective pain management?

List some examples.

A

1) patient barriers
ie fear of addiction, worry about side effects, Fear of tolerance (will not be there when I need it)

2) healthcare provider barriers. ie Inadequate pain-assessment skills, No pain-management protocols available, Concern with addiction or accidental overdose

3) healthcare system barriers.
ie Concern with creating “addicts”, Difficulty in filling prescriptions, Limitation on reimbursement for prescriptions

102
Q

Define “pain contracts”

A

Many patients on long-term opioid medications enter into “pain contracts” that state the expected responsibilities of both the patient and healthcare provider. If the patient violates the agreement or if assessment data indicate potential violation of the contract, help to identify additional resources to
aid the patient in addressing the addictive illness.

103
Q

What are some examples of Restorative and Continuing Care?

A

Pain clinics, palliative care, and hospices
1. Pain centers treat patients on an inpatient or outpatient basis.
