pulse width of 50-80 microseconds, and a frequency of 80-100
Hz.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1081.

20
Q

How are CRPS I and CRPS II treated?

A

The primary modes of treatment for CRPS focus on sympathetic
blocks, physical therapy, and oral medications such as
gabapentin and memantine. IV regional anesthesia has also
been employed for the treatment of CRPS.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1658.

21
Q

What is the primary difference between CRPS I and

CRPS II?

A

They present with the same symptoms and clinical
characteristics except that CRPS II (formerly known as
causalgia) is preceded by trauma to a nerve. CRPS II is usually
caused by high velocity injuries to large nerves (most commonly
the brachial plexus) and has an immediate onset.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1657.

22
Q

What are the treatment options for phantom limb

pain?

A

Phantom limb pain is treated with oral medications such as
gabapentin and antidepressants. Transcutaneous electrical
nerve stimulation, spinal cord stimulators, and biofeedback
have also been used in the treatment of phantom limb pain.

Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1652.

24
Q

What type of injection would be most likely to

improve symptoms in a patient with facet syndrome?

A

Medial branch blocks and facet joint injections are efficacious in
patients with facet syndrome.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1653.

25
Q

What are the potential complications from
transforaminal steroid injection and how do they
occur?

A

Injury to the brain or spinal cord can occur. Trauma to the brain
is associated with damage to the vertebral artery, vasospasm,
or a particulate embolus via inadvertant injection into the
vertebral artery. Injury to the spinal cord can occur via similar
mechanisms that involve the radicular artery adjacent to the
nerve root. In the lumbar area, anatomical variants of the artery
of Adamkiewicz also present a potential location of inadvertant
injection or trauma.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1652.

26
Q

How long would you expect that a radiofrequency
rhizotomy of a medial branch would provide relief of
symptoms in a patient with facet syndrome?

A

3-12 months
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1654.

27
Q

What are the characteristics of facet syndrome?

A

Facet syndrome typically results in pain that begins in the lower
back and radiates through the posterior thigh and ends at the
knee. Paraspinal tenderness is usually present on physical
examination and the pain is reproduced with extension and
rotation movements of the lower back.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1653.

28
Q

When would a radiofrequency rhizotomy be indicated

for a patient with facet syndrome?

A

Results from a medial branch block can have a relatively long
duration (3-6 months). If the results from a medial branch block
are short-lived, a radiofrequency rhizotomy should be

Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1653-1654.

29
Q

With what forms of chronic pain is a neuroendocrine

stress response generally associated?

A

A neuroendocrine stress response is typically only seen in
syndromes associated with severe recurring pain related to
peripheral mechanisms or significant central pain mechanisms
such as those associated with paraplegia.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1038-1039.

30
Q

What are the central mechanisms that contribute to

neuropathic pain?

A

Central mechanisms include the reorganization of neural
connections, wind-up of wide dynamic range neurons,
spontaneous neural discharges, and loss of inhibitory
mechanisms in neural segments.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1037.

31
Q

What are the peripheral mechanisms that contribute

to neuropathic pain?

A

Receptor sensitization to chemical, thermal, and mechanical
stimuli, spontaneous neural discharge, and up-regulation of
adrenergic receptors.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1037.

32
Q

What is the chief danger in performing cervical

transforaminal steroid injections?

A

The path of the needle for these blocks has been demonstrated
to be within 2 millimeters of the vertebral, ascending cervical,
and deep cervical artery making intra-arterial injection or
vascular trauma a significant risk.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 652.

33
Q

How long do epidural steroid injections relieve

symptoms? What are the implications of this?

A

Studies have demonstrated that the efficacy of epidural steroid
injections lasts no more than 3 months. Because of this, the
American Academy of Neurology recommends against the
routine use of epidural steroid injections. The argument for their
use by other clinicians is that epidural steroids can be used as a
modality to reduce the need for opioids or potent antiinflammatory
drugs during the acute phase of injury.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1651.

34
Q

What are the treatment options for pyriformis

syndrome?

A

Physical therapy combined with nonsteroidal anti-inflammatory
and muscle relaxant drugs and local anesthetic/steroid injection
directly into the pyriformis muscle.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1655.

35
Q

How do epidural steroids relieve symptoms from a

herniated nucleosus pulposus?

A

When the disc ruptures, it releases cytokines and inflammatory
mediators that cause a chemical inflammation of the adjacent
nerves. One of the mediators released in high quantities is
phospholipase A2. Epidural steroids can reduce inflammation
by inhibiting the activity of phospholipase A2. Epidural steroids
also have a local anesthetic quality and exert an antinociceptive
effect.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1651.

36
Q

What is the fundamental pathology that is believed to
underlie the allodynia and hyperalgesia associated
with persistent painful stimuli?

A

The concept of wind-up (also called central sensitization)
underlies these phenomena. Chronic C fiber stimulation can
enhance the response to subsequent stimulation and result in
neuronal excitability. As the cycle progresses, low level,
nonpainful stimuli can begin to produce pain.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1649-1650

37
Q

How many epidural steroid injections may be
performed if there is no response to the first
injection?

A

Up to three injections may be performed, but multiple injections
should not be administered within a short period of time.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1652.

38
Q

What are the possible complications from a celiac

plexus block?

A

Abdominal aortic dissection, paraplegia, orthostatic
hypotension, retroperitoneal hematoma, hematuria, pleurisy,
and transient motor paralysis.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1659.

39
Q

How do antidepressants help control chronic pain?

A

Antidepressants provide analgesia by inhibiting the presynaptic
reuptake of norepinephrine, serotonin, or both.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1055.

40
Q

What spinal pathway transmits the discriminative
features of pain such as location, intensity, and
duration?

A

The axons of most second-order neurons cross to the opposite
side of the spinal cord before forming the spinothalamic tract.
The spinothalamic tract is divided into lateral and medial tracts.
The lateral spinothalamic tract carries discriminatory features of
pain such as location, intensity, and duration while the medial
tract sends fibers to the thalamus which modulates the
autonomic and emotional perceptions of pain. The lateral
spinothalamic tract may also be referred to as the
neospinothalamic tract.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1031-1032.

41
Q

What are wide-dynamic range neurons and in which
of Rexed’s lamina are wide-dynamic range neurons
most abundant?

A

Wide dynamic range neurons are the most abundant nerve fiber
type in the dorsal horn and are found primarily in lamina V.
They carry noxious stimuli in addition to receiving input from Abeta,
A-delta, and C fibers. During repeated stimulation, widedynamic
range neurons increase their firing rate exponentially
despite no change in stimulus intensity.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1030.

42
Q

What nerves carry pain fibers from the head?

A

Pain fibers from the head are carried within the trigeminal,
facial, glossopharyngeal, and vagus nerves.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1028.

43
Q

Where are the primary afferent neurons located?

A

The primary afferent neurons are found within the dorsal root
ganglia. The dorsal root ganglia are located within the vertebral
foramina at each spinal cord level. An easy way to remember
the location of the sensory neurons is to remember SAD, or
Sensory Afferent Dorsal, meaning that the sensory neurons are
afferent and are located in the dorsal ganglion.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1028.

44
Q

What are the principal neurotransmitters in the
activation of dorsal horn neurons following painful
stimuli?

A

The principal neurotransmitters responsible for activation of
dorsal horn neurons in the transmission of noxious stimuli are
glutamate and substance P, although other neuropeptides such
as calcitonin, gene-related peptide, adenosine triphosphate,
somatostatin, and growth factors have also been implicated.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1647-1648.

45
Q

How does the stimulation of alpha-2 adrenergic

receptors in the spinal cord influence pain sensation?

A

Stimulation of alpha-2 adrenergic receptors in the spine can
produce analgesia by inhibiting nociceptive afferent fibers. It
has also been shown to produce muscle flaccidity in animal
studies by hyperpolarizing muscle neurons.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 920.

46
Q

What substances are capable of sensitizing

mechanoheat receptors to painful stimuli?

A

Histamine, bradykinin, substance P, prostaglandins,
leukotrienes, and serotonin are all capable of sensitizing A-delta
and C mechanoheat nociceptors to pain.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1033.

47
Q

Which nerve conduction pathway is most likely to be
associated with the autonomic and emotional
responses to pain?

A

The paleospinothalamic tract (medial spinothalamic tract)
projects to the medial thalamic nuclei and is associated with
autonomic and emotional responses to pain.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1031.

48
Q

At what spinal level should a cervical epidural steroid

injection be made?

A

Because the C6-C7 and C7-T1 interspaces have the largest
interlaminar distances, the injection is often made at this point
regardless of the level of the pathology and the practitioner
relies on the flow of drug to the level of pathology. This
technique can be used in all interspaces below C3-C4.
Interlaminar injections at the C2-C3 interspace have not been
described in the literature.
Longnecker DE, Newman MF, Brown DL, Zapol WM.
Anesthesiology. 2nd ed. New York: McGraw-Hill; 2012: 1576.

49
Q

At what spinal level is a lumbar sympathetic block

performed?

A

The sympathetic nerves to the lower extremities leave the spinal
cord above the L2 level and pass through a ‘gateway’
sympathetic ganglion at the L2 level. A lumbar sympathetic
block can be achieved by performing a single local anesthetic
injection just below that at the L3 level.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1075.

50
Q

What are the indications for a lumbar sympathetic

block?

A

A lumbar sympathetic block may be performed for the treatment
of chronic pelvic pain or peripheral vascular disease.
Butterworth JF, Mackey DC, Wasnick JD. Morgan & Mikhail’s
Clinical Anesthesiology. 5th ed. New York, NY: McGraw-Hill;
2013: 1074.

51
Q

What is pyriformis syndrome?

A

Pyriformis syndrome originates as pain in the buttocks. It can
occur due to trauma, surgery, infection, or an anatomical
abnormality in which the pyriformis muscle is bifurcated and a
branch of the sciatic nerve travels within one of the abnormally
split pyriformis bundles. The pain usually radiates from the
greater trochanter to the ipsilateral buttock.

Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1658-1659.

53
Q

What are the clinical characteristics of sacroiliac

disease?

A

Patients with pyriformis syndrome exhibit pain in the area of the
sacroiliac joint with radiation to the groin, medial buttocks, and
posterior thigh with occasional radiation below the level of the
knee.

60
Q

When is the optimal time to perform an epidural

block for the treatment of postherpetic neuralgia?

A

It should be performed within 2-4 weeks of the onset of the
herpes zoster rash to have the greatest effect.
Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC,
Ortega R. Clinical Anesthesia. 7th ed. Philadelphia, PA:
Lippincott Williams and Wilkins; 2013: 1657.

61
Q

What are the treatment options for postherpetic

neuralgia?

A

Antiviral drugs (acyclovir, famcyclovir, or valacyclovir)
administered during the episode of herpes zoster reduce the
duration and severity of the herpes zoster outbreak and
decrease the incidence of conversion to postherpetic neuralgia.
Epidural blocks have been shown to treat pain in many of these
patients. Anticonvulsants, antidepressants, and opioids are
also used in the medical management of postherpetic neuralgia.

Q

What is tic doloureux?

A

Tic doloureux (trigeminal neuralgia) is a painful condition
involving the trigeminal nerve (usually the V2 or V3 branches).
Like other forms of neuropathic pain such as shingles, reflex
sympathetic dystrophy, phantom limb pain, and central
postherpetic pain, it results from abnormalities in or damage to
the nervous system.
