2Spinal Cord CompressionPatient History
- Pt Demographics 55 year old female, diagnosed 1
year prior with metastatic colon cancer. This
patient had a section of colon removed in 11/02
she now has a permanent transverse colostomy.
She was admitted to Kaiser South San Francisco on
11/20/03 for Spinal Cord Compression with
paralysis of the lower extremities.
3Spinal Cord CompressionPatient History
- History of Present Hospitalization In 9/03,
multiple retroperitoneal nodes were discovered on
CT. On the advice of the physician, the pt flew
to El Salvador to visit family. On 11/19, pt
awoke with severe 10/10 back pain accompanied by
b/l weakness of the lower extremities. She was
seen in the ER in El Salvador where she received
epidural analgesia in order to sit through the
flight back to the U.S. By the end of the
flight, the pt had no sensation or movement of
the lower extremities.
4Spinal Cord CompressionDiagnostic Tests
- CT Scan A scan of the thoracic spine done on
11/20. The impression showed probable metastatic
disease to the thoracic spine. Air was seen
within the epidural space at the lower thoracic
level. Exact etiology is unknown. - MRI A follow up MRI was done of the thoracic and
lower spine that same day. The impression showed
extensive metastatic tumor involving the
cervical, thoracic, lumbar and sacral vertebrae,
with evidence or spinal cord compression at T2
and T9.
5Spinal Cord CompressionPathophysiology
- Definition Spinal cord compression damage occur
when a tumor directly enters the spinal cord or
when the vertebral column collapses from tumor
entry. Tumors may begin in the spinal cord but
more commonly spread from other areas of the body
such as the lung, prostate, breast, colon.
6Spinal Cord CompressionPathophysiology
- Direct compression or distortion of the spinal
cord may result from neoplastic infiltration of
the vertebral bodies or paravertebral spaces. - Rarely, cancerous growths may originate from
structures within the epidural space. - Nerve tracts most vulnerable to mechanical
pressure include the corticospinal and
spinocerebellar tracts and the posterior spinal
columns.
7Spinal Cord Compression Pathophysiology
- Spinal cord compression usually follows
hematogenous dissemination of a malignancy to the
vertebral bodies, with subsequent expansion of an
epidural mass. Generally, metastatic seeding
appears in the thoracic spine 70 of with the
lumbar spine being the next most involved
site.The cervical spine is affected in
approximately 10 of cases.Multiple spinal levels
are affected in about 30 of patients. - Systemic cancers with a tendency for spinal cord
metastasis include the following breast,
prostate, renal, or lung neoplasms lymphoma
sarcoma and multiple myeloma.
8Spinal Cord CompressionPathophysiology
- Spread into the epidural space may occur by means
of tumor extension through the intervertebral
foramina or hematogenous spread by way of the
Batson venous plexus. Additionally,
gastrointestinal and pelvic malignancies tend to
affect the lumbosacral spine lung and breast
cancers are more likely to affect the thoracic
spine.
9Spinal Cord CompressionPathophysiology
- Leptomeningeal metastases spread by means of
diffuse or multifocal seeding of the meninges
from systemic cancer (eg, lung or breast cancer,
melanoma, lymphoma). Consequent signs and
symptoms are referable to the brain, cranial
nerves, or spine. Evidence of spinal compromise
includes lower extremity weakness, paresthesias,
reflex asymmetry, and spinal pain.
10Spinal Cord CompressionSigns and Symptoms
- Signs and Symptoms Spinal cord compression
causes back pain, usually before neurologic
deficits occur. Neurologic deficits are related
to the spinal level of compression and include
the following - 1. Numbness
- 2. Tingling
- 3. Loss of urethral, vaginal and rectal
sensation - 4. Muscle weakness
- 5. If paralysis occurs, it is usually permanent.
- 6. Valsalva maneuvers, such as coughing,
sneezing, or straining, may exacerbate radicular
back pain.
11Spinal Cord CompressionTreatment
- Nurses caring for clients with spinal cord
compression must recognize the condition early.
The nurses assesses the client for neurologic
changes consistent with spinal cord compression.
The nurse also teaches clients and families to
recognize the symptoms of early spinal cord
compression and to seek medical assistance as
soon as possible. - Treatment is largely palliative. High-doses
radiation is usually administered to reduce the
size of the tumor in the area and relieve
compression. Radiation may be given in
conjunction with chemotherapy to treat the total
disease. Surgery is occasionally performed to
remove the tumor from the area and rearrange the
bony tissue so less pressure is placed on the
spinal cord. External back or neck braces may be
prescribed to reduce the weight borne by the
spinal column and to reduce pressure on the
spinal cord or spinal nerves.
12Spinal Cord CompressionPatient Medications

23 days throughout therapy.
14Spinal Cord CompressionPatient Medications
- InsulinDue to glucocorticoid administration.
- Dosage Sliding Scale before meals and bedtime
Action Lower blood glucose by increasing
transport into cells and promoting the conversion
of glucose to glycogen Adverse reaction rebound
hyperglycemia (Somogyi effect), hypoglycemia
Serious reaction-anaphylaxis Implications Check
type, species source, dose, and expiration date
with another licensed nurse. Do not interchange
insulins without consulting physician or other
health care professional.
15Spinal Cord CompressionRadiation Therapy
- Radiation treatment to areas of tumor compression
should be pursued after appropriate imaging and
consultation. - Cord compression from an epidural tumor is
considered one of the few emergencies in
radiation oncology. - Spinal cord tolerance to radiation depends on the
fraction size and cumulative dose.
16Spinal Cord CompressionRadiation Therapy
- Radiation treatment affects normal cells while
damaging cancer cells. Sometimes this effect on
normal cells and tissues can cause pain and
discomfort. - Skin dryness, difficulty in swallowing or skin
sores may occur. The radiation therapy specialist
can recommend a program to care for the skin to
alleviate these side effects. - Fatigue can be a disabling side effect of cancer,
cancer treatments and dealing with pain. It
restricts a person's ability to manage their
usual activities. - This patient was receiving external beam
radiation for 8 days as palliative treatment to
shrink the tumor that invaded the spinal column.
17Spinal Cord CompressionNursing Assessments and
Interventions
- Monitor and document vital signs.Rationale
Obtain info on patients overall condition - Assess neurological status including limb
strength, sensation, bladder and bowel
functionRationale Establish patients level of
consciousness. Ascertain any evidence of
increasing spinal cord compression as indicated
by motor dysfunction, weakness, ataxia, sensory
loss, numbness, tingling, loss of sensation to
pain and temperature, constipation and urinary
retention.
18Spinal Cord CompressionNursing Assessment
- Monitor blood chemistry and patient for signs of
hypercalcemia, such as confusion, drowsiness and
lethargy. Rationale Elevated calcium levels may
be associated with bone mets causing spinal cord
compression - Assess alterations in elimination of urine and
feces in terns of urgency, frequency, level of
control over function, retention, constipation
and incontinence. Rationale Early autonomic
and nervous system involvement results in
constipation and urinary retention. Bowel and
bladder incontinence develop with advanced
autonomic nervous system involvement.
19Spinal Cord CompressionNursing Assessment
- Assess patients pain level. Assess for
duration, location, type, intensity and quality.
Assess pain interventions. Consider
non-pharmacological interventions such as
relaxation, therapeutic massage and adjustment of
patients position. - Assess patients skin as there are at risk for
impaired skin integrity. Rationale Maintain
good body alignment at all times to decrease the
risk of further injury to spine.
20Spinal Cord CompressionNursing Assessment
- Assess for signs and symptoms of deep venous
thrombosis due to activity. This can lead to
pulmonary embolism, which can be a lethal
complication. Many die within one hour of onset
of symptoms or before it has been suspected. - For a DVT assess for calf and groin tenderness,
pain, sudden onset of unilateral swelling of leg
and positive Homans sign. Symptoms of pulmonary
embolism include dyspnea, chest pain,
restlessness, cough and hemoptysis. Signs
include tachypnea, crackles, pleural friction
rub, tachycardia, diaphoresis, fever and
petechiae over chest and axilla.
21Spinal Cord CompressionNursing Assessment
- Assess and monitor patient and familys
psychological status and adaptation to diagnosis
and implication on lifestyle. Feelings of
helplessness, hopelessness and depression are
common. Bed bound patients become withdrawn and
lose motivation.
22Spinal Cord CompressionNursing Diagnoses and
Interventions
- Impaired physical mobility related to
neuromuscular impairment. Interventions include
maintain proper body alignment, ROM exercises,
adequate nutrition, teach patient how to move in
bed, monitor skin area over pressure areas. - Risk for falls related to decreased or absent
lower extremity sensation and strength.
Interventions include bed in low position, side
rails up, keep frequently used items within
patients reach, provide assistance with
ambulation.
23Spinal Cord CompressionNursing Diagnoses and
Interventions
- Risk for impaired skin integrity related to
physical immobilization and loss of bladder and
bowel control. Interventions include Active or
passive range of motions, ambulate to the extend
possible, change positions every 2 hours, reduce
pressure using things like pillows, air
mattresses and bed cradles, maintain good body
hygiene, encourage adequate fluid and nutritional
intake. - Bowel incontinence related to loss of rectal
sphincter control. Interventions include Keep
area clean and dry. Monitor anal and genital
skin integrity. Record each episode including
when it occurs, amount, color and consistency.
Provide emotional support for patient.
24Spinal Cord CompressionNursing Diagnoses and
Interventions
- Ineffective Individual Coping related to
inadequate level of confidence in ability to
cope. Interventions include maintain
consistency in approach and teaching whenever
interacting with patient, monitor for and
reinforce behavior suggesting effective coping
continuously, assist patient to identify and use
available support systems before discharge from
hospital and help patient evaluate which methods
he or she have used that have not been successful
or have been only partially successful.
