Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

6. Peripheral vascular disease (PVD)
includes disorders that alter the natural flow of blood
through the arteries and veins of the peripheral circulation.
affects the lower extremities much more frequently than the
upper extremities.
Generally, a client with a diagnosis of PVD has arterial
disease (peripheral arterial disease [PAD]) rather than venous
involvement.
Some clients have both arterial and venous disease.
7. Peripheral Arterial/ Venous Disease
A chronic disorder in which partial or total occlusion
deprives the lower extremities of oxygen and nutrients
Tissue damage occurs below the level of the arterial
occlusion
Atherosclerosis - most common cause of peripheral arterial
disease
9. Peripheral Arterial Disorders (PAD)
Aka: Peripheral arterial occlusive disease
Arterial Occlusive Disorders
Lower extremity arterial disease (LEAD)
Is the arterial insufficiency of the extremities
most common cause is Arteriosclerosis Obliterans (ASO)
lower extremities are more commonly affected.
More prevalent among men 50-70 years old
10. Assessment
intermittent claudication: hallmark of the disease
rest pain: severe
is a numbness or burning, often described as feeling like a
toothache, that is severe enough to awaken clients at night.
it may be so excruciating that it is unrelieved by opioids.
elevating the extremity or placing it in a horizontal position
increases the pain, whereas placing the extremity in a
dependent position reduces the pain.
In bed, some sleep with affected leg hanging over the side of the
bed.
Some patients sleep in a reclining chair in an attempt to relieve
the pain.
11. Assessment
Coldness or cold sensitivity – Coldness in the feet with
exposure to a cold environment, associated with blanching or
cyanosis due to ischemia
extremity
Cold and pale when elevated
or ruddy and cyanotic when placed in a dependent position
nails : thickened and opaque
Skin: shiny, atrophic, and dry, with sparse hair growth.
comparison of the right and left extremities.
Bruits may be auscultated with a stethoscope
12. Assessment
Ulceration and gangrene. May be due to ischemia ot
trauma. Impaired tissue perfusion inhibits healing
process
Edema. Due to severe obstruction
Sexual dysfunction. Occlusion of terminal aorta
decreases blood supply to the penile arteries
Gangrene
muscle atrophy
13. Assessment
peripheral pulses: important part of assessing arterial
occlusive disease.
Unequal pulses between extremities or the absence
of a normally palpable pulse is a sign of peripheral
arterial disease.
The femoral pulse in the groin and the posterior tibial
pulse beside the medial malleolus are most easily palpated.

17. Diagnostic Findings
CW Doppler and ankle-brachial indices (ABIs)
Treadmill testing for claudication
duplex ultrasonography
18. Medical Management
Control hypertension
Reduce risk factors:
Control serum lipids
Weight reduction
Low fat low cholesterol diet
Daily walking
Cessation of tobacco use
Note: Patients should not be promised that their symptoms will
be relieved if they stop tobacco use, because claudication may
persist, and they may lose their motivation to stop using
tobacco
Skin and foot care
20. hemorheologic agent
Pentoxifylline (Trental)
Increase flexibility of RBCs
decreases blood viscosity by inhibiting platelet aggregation and
decreasing fibrinogen and thus increases blood flow in the
extremities.
24. SURGICAL MANAGEMENT
choice of the surgical procedure depends on the
degree and location of the stenosis or occlusion.
overall health of patient and length of procedure that can be
tolerated.
25. vascular grafting or endarterectomy
For patients, severe intermittent claudication and disabling or
when the limb is at risk for amputation because of tissue loss
palliative therapy of primary amputation rather than an
arterial bypass.
26. Endarterectomy
an incision is made into the artery
atheromatous obstruction is removed.
artery is then sutured closed to restore vascular integrity
27.
28. Bypass grafts
are performed to reroute the blood flow around the stenosis
or occlusion.
Before bypass grafting, the surgeon determines where the
distal anastomosis (site where the vessels are surgically
joined) will be placed.
The distal outflow vessel must be at least 50% patent for the
graft to remain patent.
A higher bypass graft patency rate is associated with keeping
the length of the bypass as short as possible.
29. femoral-to-popliteal graft
surgical procedure of choice if atherosclerotic occlusion is
below the inguinal ligament in the superficial femoral artery
Class. based on location of distal anastomosis
above-knee
below-knee grafts
30. Bypass grafts may be synthetic or autologous vein.
Native vein or autologous vein
greater or lesser saphenous vein or a combination of one of the saphenous
veins and an upper extremity vein such as the cephalic vein are used to
meet the required length.
woven or knitted Dacron, expanded polytetrafluoroethylene
(ePTFE, such as Gore- Tex or Impra), collagen-impregnated,
and umbilical vein.
31. Nursing Management
Maintaining circulation
Maintain skin integrity and prevent infection
Monitoring and managing potential complications
Promoting home and community-based care
32. Maintaining circulation: Post op care
Monitor the ff q hour for first 8 hours and then every 2 hours
for 24 hours
Pulses
color and temperature of the extremity
capillary refill
Sensory and motor function of the affected extremities
Note: Compare extremities
Doppler evaluation
ABI : at least once q 8 hrs for 1st 24 hrs and then OD until
discharge (not usually assessed for pedal artery bypasses).
33. Disappearance of a pulse that was present may
indicate thrombotic occlusion of the graft
Notify surgeon STAT
34. Maintain circulation
Warm environmental temperature
Place legs in slight dependency to promote arterial flow
Avoid pressure on affected extremity; use padding for support
Avoid vigorous massage of extremities
Avoid
Chilling and exposure to cold
Avoid contrictive clothing
Crossing legs
Quit smoking
Do not go barefootd
Trim toenails straight
Avoid scratching or rubbing feet
35. Exercise
may improve arterial blood flow to the affected limb through
buildup of the collateral circulation.
is individualized for each client
Contrindicated: severe rest pain, venous ulcers, or gangrene
Initiate gradually and is slowly increased
nurse instructs the client to walk until the point of
claudication, stop and rest, and then walk a little farther.
Eventually, clients are able to walk longer distances as
collateral circulation develops.
36. Positioning
To promote circulation
Still controversial
Some have swelling in extremities
Because swelling prevents arterial flow, should elevate feet at rest,
but shld be taught to refrain raising legs above heart level.
Extreme elevation slows arterial blood flow to the feet.
In severe cases, clients with PAD and swelling may sleep with the
affected limb hanging from the bed, or they may sit upright in a
chair for comfort.
avoid crossing their legs, which may interfere with blood flow.
37. Maintain skin integrity and prevent
infection
Examine skin on a daily basis
Take daily bath and dry the skin gently
Apply moisturizing cream/lotion in the skin. Avoid using
alcohol
Foot care
Wear comfortable, well fitted pair of shoes
Avoid direct heat application over the extremities
38. Monitoring and managing potential
complications
UO
central venous pressure
mental status
pulse rate and volume
permit early recognition and treatment of fluid imbalances.
39. Monitoring and managing potential
complications
Bleeding / Hematoma
can result from the heparin administered during surgery or from an
anastomotic leak.
Avoid leg crossing and prolonged extremity dependency
to prevent thrombosis.
Edema
normal postoperative finding
elevating the extremities and encouraging the patient to exercise the
extremities while in bed reduces edema.
Elastic compression stockings
care must be taken to avoid compressing distal vessel bypass grafts.
Severe edema of the extremity, pain, and decreased sensation of
toes or fingers can be an indication of compartment syndrome.
40. Promoting home and community-based
care
Assess patient’s ability to manage independently.
Determine if patient has a network of family and friends to
assist with ADL
Encourage to make the lifestyle changes necessary with a
chronic disease, including pain management and
modifications in diet, activity, and hygiene (skin care).
Ensure has knowledge and ability to assess for any postop
complications such as infection, occlusion of the artery or
graft, and decreased blood flow.
Assists in developing a plan to stop using tobacco.
41. Promote activity
Regular aerobic exercises such as walking, swimming,
jogging , bicycling
Do exercises 30-45 minutes 3-4 times a week
42. Prevention
Primary – provide info on the effects of the following:
Cigarrete smoking. Nicotene causes vaso-constriction, spasms
of the arteries, reduced circulation to the extremities. CO2
reduces O2 transport to the tissues
Hypertension. Cause elastic tissue in the arteries to be replaced
by fibrous collagen tissue reducing arterial elasticity and
increases resistance.
43. Hyperlipidemia. Contribute to atherosclerotic plaques in vessels
Obesity. Added burden on the heart and blood vessels
Physical inactivity. Compromises circulation
Emotional stress. Stimulates the sympathetic response which
results to vasocontriction
DM. Changes in glucose and fat metabolism enhances
atherosclerosis
44. Secondary prevention
Encourage clients with early symptoms to seek medical care to
prevent complications
Tertiary prevention
Rehabilitation . Exercises to develop collateral circulation.
47. ACUTE PERIPHERAL ARTERIAL
OCCLUSION
Aka: Arterial embolism and arterial thrombosis
arterial occlusions : sudden and dramatic.
Occlusion may affect the upper extremities, but it is more
common in the lower extremities.
most common cause : embolus or local thrombus
Emboli originating from heart: are most common
Risk factors
AMI within the preceding weeks
atrial fibrillation
infective endocarditis
chronic heart failure
48. Assessment
severe pain below level of the occlusion
occurs even at rest.
affected extremity : cool or cold, pulseless, and mottled.
Minute areas on the toes may be blackened or gangrenous.
"six P's" of ischemia:
pain, pallor, pulselessness, paresthesia, paralysis, and
poikilothermia (coolness) of the involved extremity.
49. Interventions
initiate treatment promptly to avoid permanent damage or
loss of an extremity.
Anticoagulant therapy with unfractionated heparin (UFH;
Hepalean*) is usually the first intervention to prevent further
clot formation.

protected from trauma.
Heating and cooling pads are contraindicated
ischemic extremities are easily traumatized by alterations in
temperature.
If possible, tape and electrocardiogram electrodes should not
be used on the extremity
sheepskin and foot cradles are used to protect the leg
from mechanical trauma.
53. PostopNursing care
Monitor affected extremity for improvement in color,
temperature, and pulse, other extremities for s/s of new thrombi
or emboli.
mild incisional pain is normal
Watch closely for complications caused by reperfusing the artery

spasms and swelling of the skeletal muscle.
Swelling of the skeletal muscles is characterized by edema, pain on
passive movement, poor capillary refill, numbness, and muscle
tenseness.
Fasciotomy (surgical opening into the tissues) may be necessary to
prevent further injury and save the limb.
55. Buerger’s disease
Inflammatory, non-lipid occlusive condition of small to medium
arteries followed by vein that impairs circulation to the legs, feet
and occasionally hands
Rare, occurs most often in men, ages of 20 and 35 years, all
races
56. Cause
Unknown

70. NURSING MANAGEMENT OF
COMPLICATIONS
Postop care amputation
Elevate stump for first 24 hours to promote venous return and
minimize edema.
The incision is monitored for signs of hematoma (unapproximated
suture line, discoloration or ruddy color changes of the skin along the
suture line, tenderness with palpation, or oozing of dark blood from
the suture line).
Assess fit of elastic bandages and ensures integrity of wrap and
continued ability to fit two fingers between layers of wrap.
Distal skin color and warmth are assessed, if accessible, and recorded.
Elastic bandages are removed and reapplied as prescribed by the
surgeon (eg, every 6 hours using figure-of-eight turns).
71. NURSING MANAGEMENT

72. Discharge planning
Assess ability to manage independently.
Assist in developing a plan to stop using tobacco and to
manage pain.
Encourage to make the lifestyle changes necessary with a
chronic disease, including modifications in diet, activity, and
hygiene (skin care).
Determine whether patient has a network of family and
friends to assist with ADL.
Ensure that patient has knowledge and ability to assess for
any postoperative complications such as infection and
decreased blood flow.
73. Lifestyle and home remedies
Take care of fingers and toes
Check the skin on arms and legs daily for cuts and scrapes,
keep in mind that if lost feeling to a finger or toe may not feel, for
example, a cut when it happens.
Keep your fingers and toes protected and avoid exposing them to cold.
Low blood flow to extremities means body can't resist infection as easily.
Small cuts and scrapes can easily turn into serious infections.
Clean any cut with water, apply antibiotic ointment and cover it with a clean
bandage.
Keep an eye on any cuts or scrapes to make sure they're healing.
If they get worse or heal slowly, see doctor promptly.
Visit your dentist regularly to keep gums and teeth in good health and
avoid gum disease, which in its chronic form is associated with Buerger's
disease.

artery
An aneurysm is a localized
sac or dilation formed at a
weak point in wall of aorta
Can be located anywhere
along the aorta

tunica layers and they separate.
the blood is contained by the
surrounding tissues, with
eventual formation of a sac
communicating with the artery
(or heart).
If the separation continues, a
clot may form, resulting in a
dissecting aneurysm.

80. Etiologic Classification of Arterial
Aneurysms
atherosclerotic changes in the aorta
Congenital: Primary connective tissue disorders (Marfan’s
syndrome, Ehlers-Danlos syndrome) and other diseases (focal
medial agenesis, tuberous sclerosis, Turner’s syndrome, Menkes’
syndrome)
Mechanical (hemodynamic): Poststenotic and arteriovenous
fistula and amputation-related
Traumatic (pseudoaneurysms): Penetrating arterial injuries,
blunt arterial injuries, pseudoaneurysms
Inflammatory (noninfectious): Associated with arteritis
(Takayasu’s disease, giant cell arteritis, systemic lupus
erythematosus, Behçet’s syndrome, Kawasaki’s disease) and
periarterial inflammation (ie, pancreatitis)
84. Aortitis
is inflammation of the aorta, particularly of the aortic arch.
Two types
Takayasu’s disease
occlusive thromboaortopathy
is uncommon
syphilitic aortitis
Rare
85. Aorta
main trunk of arterial system
divided into
(1) ascending aorta (5 cm [2 inches] in diameter, contained in
the pericardium)
(2) aortic arch (extending upward, backward, and downward)
(3) descending aorta
86.
87. Thoracic aorta is above diaphragm
Abdominal aorta is below the diaphragm.
further divided as
suprarenal (above renal artery level)
perirenal level (at renal artery level)
infrarenal (below renal artery level).

89. Takayasu’s disease
chronic inflammatory disease of the aortic arch and its branches
affects young or middle-aged women; Asian descent
Cause
nonatherosclerotic
exact pathologic mechanism is unknown
thought to be immune complex mediated
progresses from a systemic inflammation with localized arteritis to
end-organ ischemia bcoz of large vessel stenosis or obstruction.

111. Diagnostic Findings
Duplex ultrasonography or CT
used to determine the size, length, and location of the aneurysm
Ultrasonography
Watchful Waiting Period
For sml aneurysm
conducted at 6-month intervals until aneurysm reaches a size at
which surgery to prevent rupture is of more benefit than the
possible complications of a surgical procedure.
Some aneurysms remain stable over many years of
observation.
112. Conventional angiography
Angiography is used to diagnose the renal area. In this
instance, an endoleak represented continued pressurization of
the sac.
113.
114. Gerontologic Considerations
Most occur ages of 60 and 90 years.
Rupture is likely with coexisting hypertension and with
aneurysms wider than 6 cm.
In most cases at this point, the chances of rupture are greater
than the chance of death during surgical repair.
If the elderly patient is considered at moderate risk for
complications related to surgery or anesthesia, the aneurysm
is not repaired until it is at least 5 cm (2 inches) wide.
117. Management
Size- <5cm and asymptomatic- follow up with serial
ultrasound every 3-12 months
>5cm elective repair
Growth rate- normally 2-8mm/year, if > 4mm/year consider
elective surgery
Symptomatic – mandates repair
control blood pressure
Systolic pressure is maintained at about 100 to 120 mm Hg with
antihypertensive medications
Correct risk factors
Pulsatile flow is reduced by medications that reduce cardiac
contractility (eg, propranolol [Inderal]).
118. SURGICAL MANAGEMENT
Surgery : treatment of choice for abdominal aneurysms wider than
5 cm (2 inches) wide or those that are enlarging
Endoaneurysmorrhaphy- opening the sac and suturing a prosthetic
graft to the normal aorta within the aneurysm
(Teflon/Dacron/Gortex)
Endovascular repair
Elective aneurysm repair
Via traditional open laparotomy
standard treatment

Insert a Foley catheter
Establish large-bore intravenous access
Monitor central venous pressure or establish Swan-Ganz
catheterization (if indicated)
Prepare the skin from the nipples to the mid thigh
Administer general anesthesia (with or without epidural
anesthesia)

121. Post Op Nursing Interventions
Thoracic Aneurysm Repair
Thoracotomy or median sternotomy approach is used
Aneurysm is exposed and excised and a graft or prosthesis is
sewn onto the aorta
Total cardiopulmonary bypass is necessary for excision of
aneurysms in the ascending and arch of the aorta
Partial cardiopulmonary bypass for descending aneurysms
122. Monitor for signs of hemorrhage
Monitor chest tubes for an increase in chest drainage
Assess sensation and motion of all extremities and notify
physician for deficits
Monitor serum creatinine, BUN and hourly outputs

132. DISSECTING AORTA
Occasionally, in an aorta diseased by arteriosclerosis, a tear
develops in the intima or the media degenerates, resulting in
a dissection
133. Pathophysiology
Arterial dissections (separations) are commonly associated with poorly
controlled hypertension;
three times more common in men than in women
occur most commonly in the 50- to 70-year-old age group
Dissection is caused by rupture in the intimal layer.
A rupture may occur through adventitia or into the lumen through the intima,
allowing blood to reenter the main channel and resulting in chronic dissection
or occlusion of branches of the aorta.
As the separation progresses, the arteries branching from the involved area of
the aorta shear and occlude. The tear occurs most commonly in the region of
the aortic arch, with the highest mortality rate associated with ascending aortic
dissection. The dissection of the aorta may progress backward in the direction
of the heart, obstructing the openings to the coronary arteries or producing
hemopericardium (effusion of blood into the pericardial sac) or aortic
insufficiency, or it may extend in the opposite direction, causing occlusion of
the arteries supplying the gastrointestinal tract, kidneys, spinal cord, and legs.
134. Clinical Manifestations
Onset of symptoms - usually sudden.
Severe and persistent pain
tearing or ripping
anterior chest or back
extends to shoulders, epigastric area, or abdomen.

146. Raynaud’s disease
is a form of intermittent arteriolar vasoconstriction that
results in coldness, pain, and pallor of the fingertips or toes.
Vasospasm of the arterioles and arteries of the upper and
lower extremities; causes constriction of the cutaneous
vessels
occurs more frequently in cold climates and during winter
147. Raynaud's phenomenon Raynaud's disease
usually unilaterally. occurs bilaterally.
occurs in people older than occur between the ages of
30 years of age 17 and 50 years
can occur in either sex more common in women
148. The pathophysiology is the same for
both entities.
Clients often have an associated systemic connective tissue
disease, such as systemic lupus erythematosus or progressive
systemic sclerosis.
As a result of vasospasm, the cutaneous vessels are
constricted and blanching of the extremity occurs, followed
by cyanosis. When the vasospasm is relieved, the tissue
becomes reddened or hyperemic. The client's extremities are
numb and cold, and he or she may complain of pain and
swelling.
Ulcers may also be present. These attacks are intermittent
and can be aggravated by cold or stress. In severe cases, the
attack lasts longer and gangrene of the digits can occur.
149.
150. Cause
The etiology is unknown.
many have immunologic disorders (scleroderma, systemic
lupus erythematosus, rheumatoid arthritis), obstructive
arterial disease, or trauma
associated with smoking
Rarely leads to gangrene
151. Prognosis
Varies
some patients slowly improve, some become progressively
worse, and others show no change.
Ulceration and gangrene are rare
however, chronic disease may cause atrophy of the skin and
muscles.
With appropriate patient teaching and lifestyle modifications,
the disorder is generally benign and self-limiting.
152. Clinical Manifestations
Classic clinical picture - Triphasic color changes in the
hands
Blanching (pallor or white) of the fingers after exposure to
cold or stress due to vasoconstriction and spasm
Cyanosis (blue) follows because of oxygen deprivation of the
tissues
Red skin as exaggerated reflow (hyperemia) when oxygenated
blood returns to the digits after the vasospasm stops.
The characteristic sequence of color change of Raynaud’s phenomenon is described as
white, blue, and red.
153.
154.
155. Symptoms
Numbness, tingling, and burning pain occur as the color change
bilateral and symmetric
may result from defect in basal heat production that eventually
decreases the ability of cutaneous vessels to dilate.
Episodes may be triggered by emotional factors or by unusual
sensitivity to cold.
Generally unilateral and affecting only one or two digits, the
phenomenon is always associated with underlying systemic disease.
Attacks are intermittent and can occur with exposure to cold or
stress
Affects primarily the hands less commonly the feet
157. Medical Management
Avoid trigggers (e.g., cold, tobacco, stress) that provoke
vasoconstriction
Medications
Sympathectomy
Amputation
158. Vasodilating agents
Commonly prescribed drugs are
nifedipine (Procardia)
cyclandelate (Cyclospasmol)
phenoxybenzamine (Dibenzyline)
help to relieve the symptoms
can cause uncomfortable S/E (facial flushing, headaches,
hypotension, and dizziness)
159. Sympathectomy
For severe symptoms that cannot be alleviated by drugs
lumbar sympathectomy
physician cuts sympathetic nerve fibers that cause
vasoconstriction of blood vessels in the lower extremities.
effective when experiencing foot symptoms.
sympathetic ganglionectomy
for upper extremities, a similar procedure
may provide symptom relief.
long-term effectiveness is questionable.
160. Education of client is important in
prevention of complications.
Minimize exposure to cold
remain indoors as much as possible during cold weather
wear layers of clothing when outdoors
hats and mittens or gloves should be worn at all times when
outside.
Use fabrics specially designed for cold climates (e.g., Thinsulate)
warm up vehicles before getting in
To avoid touching cold steering wheel or door handle, which could elicit
an attack.
during summer, a sweater should be available when entering air-
conditioned rooms.
Maintain warm body temperature
161.
162. Methods to prevent vasoconstriction
Avoid all forms of nicotine; Smoking cessation, nicotine gum
or patches used to help people quit smoking may induce
attacks
Avoid decongestants and caffeine
163. Nursing Management
decrease stress
help the client to identify stressors and provides suggestions for
reducing them.
Stress management classes
Avoid situations that may be stressful or unsafe.
Safety
Handle sharp objects carefully to avoid injuring the fingers.
Inform abt postural hypotension that may result from
medications (ex: calcium channel blockers)
safety precautions related to alcohol, exercise, and hot weather.
166. Thoracic outlet syndrome
is a compression of the subclavian artery at thoracic outlet by
anatomic structures, such as a rib or muscle.
arterial wall may be damaged, producing thrombosis or
embolization to distal arteries of the arms.
