C. Perception :
Sensation is integrated in the sensory cortex especially in parietal lobe. The ability to recognize the
object is impaired. Recognition is observed by any sense e.g. sterognosis, the ability to perceive the
object by touch. Absence of ability is called “agnosia”.
Aprexia is another perceptual problem refers to inability to perform skillful, purposeful motor
function.
-Constructional Aprexia :- impairment in producing designs in two or three dimension to copying,
drawing or constructing may be due to damage of occipitoparietal lobe.
-Dressing Aprexia :- patient can not dress accurately due to lesion in occipital or parietal lobe.
-Idomotor Aprexia :- unable to imitate gestures or perform a purposeful motor task on command. It is
due to lesion in parietal lobe.
-Kinesthetic Aprexia:- It is loss of kinesthetic memory pattern. Patient is unable to perform a
purposeful motor task although it is understood.
D. Sensory status:-
This depends on patient co-operation, alertness and responsiveness. The person should be relaxed with
eyes closed to avoid recovering visual clues sensation should be tested to both sides of same area.

E. Assessment of Cranial Nerves: -
a) Olfactory nerve: - (Cr-1)
test for smell- ask the patient to close one nostril and close the eyes and sniff from bottle.
b) Optic nerve: - ( Cr-2)
Observe by visual field and visual acuity
c) Occulumotor, trochlear & abducens :- (Cr-3,4,6)
check the eye movement & movement of extraoccular muscle.
d) Trigeminal nerve :- (Cr-5)
The sensory part can be examined by touching or pricking, ophthalmic, maxillary & mandibular areas.
e) Facial nerve :- (Cr-7) mixed
ask the patient to smile, close both eyes, look upward, wrinkle the forehead, show the teeth. In
abnormality patient will unable to do these activities.
f) Acoustic nerve :- (Cr-8)
it is tested by turning fork
g) Glosso Pharygeal & Vagus nerve:-
supplies to posterior to pharyngeal wall, normally when wall is touched there is a contraction of the
muscles.
h) Hypoglossal nerve :-
motor nerve, tongue is firstly inspected if any lesion is present tongue deviated to that lesion.
F. Motor Status: -
Gait & stance are complex activities require muscle strength, coordination and balance. Ataxia refers
to the lack of coordination and purposeful walking. For assessment patient is asked to walk naturally
then on heal to toe in straight line.
To evaluate stance patient is asked to close the eyes and then close the feet together. If patient has no
problem, he can stand with balance.
For muscle strength ask the patient to grasp the nurses both hands and then squeeze them
simultaneously.
For testing the co-ordination ask the patient to touch the nose then touch the doctor / nurses hand.
Normally he can do that.
A. Reflexes :-
This is predictable response that resulting from nerve input over reflex are tendon.
Four points are important for that
0 = absent
1 = Weak response
2 = Normal response
3 = Exaggerated response
4 = Hyper reflexia with colonies
we observe reflex in calcaneal tendon of soleous muscle, Bicep reflex in bicep tendon, triceps in
triceps tendon, patellar in patella tendon, kerning reflex and brudzinski reflex
Diagnostic Tests
2. C.T Scan : -
This makes use of narrow beam of x-ray to scan head in successive layers. The images that are
produced provide cross sectional view of the brain with distinguish difference in tissue densities of the
skull, cortex, sub-cortical structure & ventricles. The image is displayed on a T.V monitor & is
photographed. Lesions in brain are seen variations in tissue density differing from normal brain tissue.
Possible tumor masses, brain infarction, displacement of the ventricle etc can be observed. The patient
lies fixed on the adjustable table while scanning system rotates around the head. It is non-invasive,
painless & high degree of sensitivity for detecting lesion
Patient preparation involves explaining the test producer and teaching about procedure. Patient is also
taught about some sensation like light heatedness, dizziness etc. relaxing techniques should be
introduced to relieve anxiety. Removing jewelry or other material from neck, ears etc.

Cerebral angiography is an x-ray study of cerebral circulation after contrast medium has been injected
into selected artery. This is a valuable tool for investigating vascular disease and arteriovenous
malformation.
Patient Preparation: -
Patient should be well hydrate, and clear liquids are usually permitted up to the time of
study.
Instruct the patient to remain immobile during the imaging procedure.
Be sure that groin area is shaved for procedure.
Observe the injection site for the hemorrhage & hematoma.
Ice cap may be applied on the puncture site for relief.
5. Myelography: -
It is x-ray of spinal subarachnoid space following the injection of contrast agent into spinal
subarachnoid space through lumber puncture. It out lines the spinal subarachnoid spaces spinal cord,
tumor, cysts etc.
After injecting contrast medium the head is tilt down.
After Procedure:
Patient head should be elevated 30-50 degree to reduce the rate of upward dispersion of
the medium.
If agent used, as contrast medium is oil based patient should lie prone for 2-3 hours and
recumbent position for 12-24 hours to reduce C.S.F leakage and decrease headache.
Check pulse, BP etc.
Check punctured area.
Check for any leakage.
6. Electroencephalography ( EEG) :-
It represents a record of the electrical activity generated in the brain & obtain through the electrodes
applied on scalp surface.
It is useful for testing seizure disorder such as epilepsy. It is also an indicator of brain death.
1. Before EEG tranquilizers should be with held 24-48 hours before procedure.
2. Coffee, tea, cola, drinks should be omitted in the meal before test.
3. Inform the patient procedure will take 45-60 minutes.
4. Inform patient that it does not cause electric shock

1) Parkinsonism or Parkinson’s disease
It is neuromuscular disorder caused by deficiency of Dopamine level in body due to decreased
production of dopamine by dopaminergic neurons
Parkinsonism is the name given to a disturbance of motor function characterized by expressionless
faces, a stooped posture, slowness of voluntary movement festinating gait (progressively shorter
accelerated steps), muscle rigidity and pill rolling tremors. This disease was named Parkinsonism
because of after the work of James Parkinson, who wrote on “shaking palsy” in 1817. which now
called as idiopathic Parkinsonism
Causes: -
This disease affects the men & women usually after the age of 50 years.
Genetic factor
Antipsychotic medication.
Encephalitis
Ischemia
Neurotoxins such carbon monoxide
Pathogenesis:-
The dopaminergic neurons of the substantia Nigra project to striatum and their degeneration on
Parkinson’s disease is associated with the reduction in the striatal dopamine content with in the basal
ganglia. Dopamine is neurotransmitter responsible for controlling the motor movement. Dopamine has
inhibitory effect & acetylcholine has an exciting effect. When the exciting activity of acetylcholine is
inadequate balance by dopamine & individual has difficulty in controlling and initiating voluntary
movement Parkinsonism disease causes extra pyramidal tract impairment that control the movement.
Clinical Findings:-
Tremors
Rigidity
Bradykinesia (slow movement)
Expressionless faces
Stooped posture
Shortened accelerated steps
Pill rolling tremors
Widened palpebral fissure
Repetitive tapping: over bridge of nose
Semi flexed arms
Produce sustained blink response
Difficulty in initiating movement.

Delusion
Dry mouth
Confusion
Sleep disturbance
Nursing Care:-
1. Perform range of motion exercise to all joints for three times daily.
2. Massage & stretch muscles to reduce stiffness.
3. Pay attention to posture. Try to walk with the hands clasped behind.
4. Avoid staying on one position for prolonged time and keep altering position regularly.
5. Reduce the risk of injury by advising use of assistive device.
6. Monitor weight once a week.
7. Evaluate Dysphagia and modify diet to increase case chewing and swallowing.
8. Avoid high protein meal at time of medication.
9. Ensure adequate fiber diet and fluid intake to prevent constipation.
10. Use stool softeners if needed.
11. Monitor for depression.
12. Educate the patient about therapy & its side effects.
13. Avoid vitamin supplement with products that contain vitamin B6 (pyridoxine) because it
increase the conversion of Levodopa in liver, which decrease the amount of available for
conversion to dopamine in brain.

2) Myasthenia Gravis
Myasthenia gravis is neuromuscular disorder thought to be due to the presence of an antibody against
acetylcholine receptors at the neuromuscular junction, characterized by abnormal fatigability.
Classification
Class I: Any eye muscle weakness, possible ptosis, no other evidence of muscle weakness elsewhere
Class II: Eye muscle weakness of any severity, mild weakness of other muscles
Class III: Eye muscle weakness of any severity Moderate weakness of other muscles
Class IV: Eye muscle weakness of any severity, severe weakness of other muscles
Causes:-
Auto antibodies (HLADr3).
Thyrotoxicosis.
Thymoma (tumor of the thymus gland).
Rheumatic Arthritis
Family History.
Pathophysiology
Myasthenia gravis is an autoimmune disease. There is a slight genetic predisposition: particular HLA
types seem to predispose for MG (B8 and DR3 with DR1 more specific for ocular myasthenia). Up to
75% of patients have an abnormality of the thymus; 25% have a thymoma, a tumor (either benign or
malignant) of the thymus, and other abnormalities are frequently found.In MG, the auto antibodies are
directed most commonly against the acetylcholine receptor (nicotinic type), the receptor in the motor
end plate for the neurotransmitter acetylcholine that stimulates muscular contraction. Some forms of
the antibody impair the ability of acetylcholine to bind to receptors
Sakhawat Baloch 7
Nursing Instructor SON Male Jacobabad
Medical surgical Nursing-III
Diagnostic Evaluation:-
Chest x-rays to demonstrate coexisting thymoma.
Injection of edrophonium ( Tensilon), facilitates transmission of impulses to myoneural
junction with in 30 seconds of injection, myasthenia gravis patients improve the severity of
disease.
Serum HLA antigen Dr3.
Medication :-
Anticholenestrase drugs provides symptomatic relief, with out influencing the course of
disease - Pyridostigmine 30-180mg (averge 60mg) 4 times daily.
Thymectomy usually leads to asymptomatic relief should be considered in all patients.
Cortisone is indicated in patients who poorly response to pyridostgmine.
Nursing Care :-
When there is severe weakness of abdominal and chest muscles, patients feels difficulty in
coughing and breathing. Chest physical therapy including postural drainage to mobilize the
secretion and suction to remove the secretions.
Patient should take medicine 30 minutes before meal for maximal muscle strength.
Plan adequate rest throughout day.
Setting a daily schedule and spacing the activities.
Extreme muscular activities should be avoided.
Artificial tears in the eyes are administrated to prevent from corneal injury when eyelids do
not close completely.
Patient is assessed for drooling, regurgitation, chocking, suctioning should be ready because
aspiration of material may occur.

Trigeminal Neuralgia (Tic Douloureux)
Trigeminal neuralgia affects the fifth cranial nerve causes intense paroxymal pain in one or
more branches trigeminal nerves. CNS has both motor and sensory branches. The sensory
branches are involve in trigeminal neuralgia. Primarily, the maxillary and mandibular
branches. The pain is similar to electric shock or a burning sensation.
Causes:-
No etiology has been found for the disorder although risk factors have been identified. Major
initiating pathologic events may include :
Nerve compression
Herpes virus infection
Infection of teeth and jaw
Clinical Findings :-
Sakhawat Baloch 9
Nursing Instructor SON Male Jacobabad
Medical surgical Nursing-III
1. contraction of some facial muscles such as sudden close of eyes twist of mouth.Hence
named as tic douloureux (painful twist)
2. The pain of this neuralgia is felt in the skin, not in deep structures.
3. The attacks are said to feel like stabbing electric shocks, burning, pressing, crushing or
shooting pain that
4. Various triggers may commonly precipitate a pain attack.
5. Light touch or vibration is the most provocative.
6. Activities such as shaving, face washing, or chewing often trigger an episode
7. A draft of cold air and direct pressure against the nerve trunk may also cause pain.
Slightly touch may start a paroxysm.
Management :-
The anticonvulsant agent such as Carba mazepine (Tegretal) and Phenytoin (Dilantin) relieve the pain
in most patient by reducing the transmission of impulses at certain nerve terminals. If pain does not
relieve the surgery is done i.e. percutaneous radio frequency rhizotomy for total pain relief. Gama
Knife radio surgery, Retrogasserion rhizotomy for permanent anesthesia Micro vascular
decompressing for pain relieving with out loss of sensation.
Nursing care of patient with trigeminal neuralgia include recognizing that certain factors may
aggravate the pain such as food that is too hot or too cold. The nurse can prevent or reduce this pain in
variety of ways such as providing cotton pads and room temperature water for washing the patient’s
face. Instruct the patient to take food and water at room temperature, to chew on unaffected side.
Introduction of Trigeminal Nerve :-
Trigeminal nerves has both functions

Bell’s Palsy (Facial Paralysis)
Tumour: facial neuromas, congenital cholesteatomas, acoustic neuromas, parotid gland neoplasms,
Herpes zoster:Herpes zoster is essentially a herpes zoster infection that affects cranial nerves VII
(facial nerve) and VIII (vestibulocochlear nerve).
Path physiology
A popular theory proposes that inflammation and swelling of the facial nerve results in
compression of the nerve within the temporal bone. The facial nerve courses through a portion of
the temporal bone commonly referred to as the facial canal. The first portion of the facial canal, the
labyrinthine segment,The edematous inflamed nerve becomes compression to the damage or its
nutrient vessel is occluded to the point of producing Ischemia, necrosis of nerve with in the long canal.
There is distortion of face from paralysis of facial muscles, increased lacrimation (tearing) and painful
sensation of the face, behind the ear and in the eyes. The patient is unable to speak and eat on effected
side because of weakness of the muscles.
Signs and Symptoms: -
The onset of Bell’s palsy is often accompanied by an outbreak of herpes vesicles (Herpes:
any inflammatory skin disease marked by the formation of small vesicle in cluster to such
disease caused by herpes virus) or around the ear.
Patient complains pain around the ear or behind the ear.
Flaccidity of the effected side of the face.
Drooping of the mouth.
Unable to close the eyelids with upward movement.
Widened palpebral fissure.
Unable to smile.
Unable to show the teeth.
Unable to make the wrinkles on the forehead.
Can’t move eyebrows upward.

Malnutrition.
Dehydration.
Corneal abrasion.
Muscle stretching etc
.
Medical Managemet: -
Tab. Predisone 80mg daily in divided dose for 5-7 days. Such as prednisone, are used to reduce
swelling and inflammation of the facial nerve. Whether or not this treatment speeds up healing and
improves the chances for complete recovery has not been determined. Once the decision has been
made to use corticosteroids, they should be started within 2 days after symptoms develop.
Treatment is continued for 1 to 2 weeks.
Tab. Acyclovir (Zovirex) 200mg four times a day for 5 days. Treatment with antiviral agents such
as acyclovir may be beneficial. Acyclovir and prednisone used together are more effective than
prednisone alone. The acyclovir-prednisone combination is most effective when begun as soon as
possible after the onset of symptoms. One recent study found that patients had a 100% recovery
rate when treated within 3 days of symptom onset, compared to an 84% recovery rate when
treatment was delayed 4 days or longer
Tab/Inj. Neurobian (B1, B6,B12) Three times daily. OR
Tab/Inj. Methyl Cobal (B12) 1 amp. I/M three times a week.
Tab. Paracetamol / Brufeen to relieve the pain.
Nursing Management: -
Hot wet packs can reduce the discomfort of the herpic lesion and relieve the pain.
Protection of the face from cold & drafts.
Maintainace of good nutrition.
Teach patient to chew the food on unaffected side.
Maintainance of oral hygiene.
Teach patient to safety use of heat & massage.
Instruct the use of medicine.
Teach importance protecting the eyes from infection.

Head Injury
Trauma to scalp, skull and brain is called head injury or Injury of the skull is called head injury.
1. Scalp Injury: -
Because of many blood vessels, the scalp bleeds profusely when injured. Trauma may result in an
abrasion, contusion, laceration etc. the areas are mostly irrigated to prevent from the infection.
2. Fracture Of Skull: -
This is break in the continuity of the skull caused by trauma. It may occur with or without damage of
brain. It is of two types. 1. Open fracture in which the dura is torn and 2. Closed fracture in which dura
is not torn.
Clinical Features: -
Localized and persistent pain.
Swelling in the region of fracture.
In case of fracture of cranial base, there is hemorrhage from nose, ear.
Some times CFS may escape out of the ear and due to involvement of durametter.
Halo sign this indicates involvement of durametter. In this sign blood is surrounded by
CFS from ear and nose.
Diagnostic Evaluation: -
1. Skull X-ray.
2. C.T scan
3. MRI
3. Brain Injuries: -
The most important consideration in any head injury whether or not the brain has been injured. The
serious brain damage causes brain cell death due to cut of oxygen supply to tissue. Brain injury causes
intracranial hemorrhage and hematoma. C.T scanning and MRI are used evaluate the natural pare of
brain involvement.

Epilepsy
Epilepsy is a common chronic neurological disorder characterized by recurrent unprovoked seizures.
Epilepsy is usually controlled, but not cured, with medication, Epilepsy is a condition, in which a
person has spontaneously recurring seizures caused by chronic defect of the brain. It may be associated
with loss of consciousness. The basic problem is thought to be an electrical disturbance in the nerve
cell in one section of brain, causing them to emit abnormal, recurring, uncontrolled discharges.
Causes: -
Family history.
Degenerative disease ( Alzheimer’s disease).
Metabolic disorders.
With drawal from drug.
Hypoglycemia
Hyperglycemia
Congenital defect.
C.N.S tumor.
Pathophysiology: -
A seizure can be cause by any process that disrupts the cell membrane stability of a neuron. The point
at which the cell membrane, becomes destabilized and uncontrollable electrical discharge begins is
called seizure threshold. In epilepsy abnormal neurons seem to undergo spontaneous firing. Any
stimulus that cause C.N.S neuron to depolarize induces tendency to spontaneous firing.
Classification: -
A. Partial Seizures: -
In this type only restricted part of one cerebral hemisphere has been activated. The ictal features
depends on the area of brain that is involved. It is divided into two types.
1. Simple partial
2. Complex partial.
a) Simple Partial: -
In this the consciousness is preserved and manifested by motor symptoms (convulsive jerking) or
sensory symptoms (paresthesis or tingling).
b)Complex: -
In this consciousness is impaired and accompanied with psychic symptoms and signs such as illusion
and hallucination.
B. Generalized Seizure: -It is of two types:
1. Absence seizure ( Petit Mal)
2. Tonic Clonic seizure ( Grand Mal)
a. Petit Mal: -
These are characterized by impairment of consciousness, with mild clonic tonic or atonic components
onset and termination attacks are abrupt. The impairment of the external awareness is so brief that
patient is unaware of it.
b. Grand Mal: -
Sakhawat Baloch 15
Nursing Instructor SON Male Jacobabad
Medical surgical Nursing-III
In this type, the seizures are characterized by sudden loss of consciousness. The patient become rigid
and falls on the ground and respiration is arrested. The tonic usually last less than one minute followed
by Clonic phase in which jerking movement occurs in the body. And then followed by coma. During
this phase tongue can be bitten.
Diagnostic Evaluation: -
E.E.G.
C.T scan.
MRI.
Rx: -
Phenytoin sodium 100mg B.D.
Carbamazapine 100-200mg OD or BD.
Or Sodium Valproate – initially 600mg daily in two divided doses usually maintain 1-2
daily.
Nursing Care: -
Ensure patient’s airway.
Suction as needed.
Stay with patient until seizures has passed.
Place mouth gag or pencil or other substance between teeth to prevent from tongue
bitten.
Remove all the sharp things from place.
Keep the patient on ground.
Remove or loose tight clothes.
Monitor vital L.O.C.

Increased Intra cranial Pressure
Normal intra cranial is the pressure that is exerted by the total volume from three components with in
the skull, these are brain tissue, intra cranial blood volume and cerebrospinal fluid. Normal intra
cranial pressure in lateral position is 60-150 mm of H2O & in 30 degree head elated is 0-50 mm of
H2O. The rigid cranial vault contains 1400 grams of brain tissue, 75 ml blood and 70 ml C.S.F
Under normal condition minor changes may occur due to coughing, sneezing, straining etc.
Pathological condition causes I.I.C.P: -
a) Head injury
b) Brain tumor
c) Cerebral edema.
d) Brain hemorrhage.
e) Brain Ischaemia.
f) Stroke
g) Intra cranial surgery.
h) Brain infection.
Pathophysiology: -
According to Monro-Killie hypothesis, any condition that increase one or more of intra cranial
content must cause reciprocal change in the remaining contents. And increase intra cranial
pressure occurs. As intra cranial volume increase, the compensatory mechanism takes place.
C.S.F filled space are compressed by surrounding brain tissue and distribute the C.S.F to
lumber and also blood vessels especially veins. These compensatory mechanisms maintain the
equilibrium. But these mechanisms are exhausted when changes are continuous, when volume
overwhelms, the compensatory system, the intra cranial pressure rises.
As pressure with in skull increase, the cerebral blood vessels are compressed, causing
reduction in cerebral blood flow and result in Ischaemia. If this Ischaemia occurs 3-5 minutes,
the brain is suffer irreversible damage.
Brain Death: -
Cessation of blood flow results in cerebral hypoxia leading to brain death.
Clinical Features: -
Altered level of consciousness.
Spontaneous movement, movement caused by noxious stimuli such as pinching and
injection.
Severe headache, which is constant.
Purposeless movement.
Increased blood pressure.
Increased temperature / fever.
Decreased pulse.
Decreased breathing.
Arterial hypertension.

Nursing Care: -
Assess the patient for bradycardia and increased blood pressure, which are initial features of
I.I.C.P.
Elevation of the head of the bed to 30 degree with head in a neutral position to reduce the
cerebral edema.
Extreme rotation of the neck and flexion of the neck are avoided because compression of
jugular vein cause increased intra cranial pressure.
Emotional stress should be avoided because these conditions may cause alteration in brain.
Abdominal distention, which increases intra cranial pressure should be noted.
Clearance of the airway should be done.
Control the coughing if it is in severe condition.
Maintain the fluid balance.
Manage the potential complications.
Unconsciousness
Unconsciousness is an abnormal state in which the patient is unknown of self or environment.

Migraine
This is symptom complex characterized by periodic and recurrent attacks of severe headache. The
cause of migraine has not been clearly demonstrated but it is vascular disturbance occurs more
commonly in women and has strong familial tendency.
It is also can be defined as” lateralized throbbing headache that occurs episodically.
Physiologically, the migraine headache is a neurological condition more common to women than to
men. The French word migraine derives from the Greek hemicrania (half skull) and the Old English
megrim (severe headache).
Pathophysiology: -
The signs and symptoms of migraine result due to cortical Ischemia. The typical attack begins with
vasoconstriction affecting the arteries of the scalp and cerebral arteries. Extra cranial and intracranial
blood vessels than dilate causing pain and discomfort. Studies suggest that dilated arteries become
hyper permeable and local inflammatory reaction occurs in painful dilated arteries. It is proposed that
vasoactive substance histamine, serotonin, participate in the inflammatory reaction.
Causes of Migraine: -
1. Stress.
2. Excessive sleep.
3. Lack of sleep.
4. Familial history.
5. Menstruation.
6. Constipation.
7. Alcohol.
8. Oral contraceptive.
9. Vascular disorder.
10. Stress.
Clinical Features: -
A. Aura phase:
Lasts up to 30 minutes.
Visual disturbance
Dizziness

Photophobia.
Nausea & vomiting.
Pulsation of external carotid artery.
Stars, sparks unformed light flashes.(luminous hallucination)
Duration of this period ranges from hours to days.
C. Recovery Phase:
in this phase patient feels well.
Diagnostic criteria:
A. At least five attacks fulfilling criteria B-D
B. Headache attacks lasting 4-72 hours [when untreated]
C. Headache has at least two of the following characteristics:
1. Unilateral location
2. Pulsating quality
3. Moderate or severe pain intensity
4. Aggravation by or causing avoidance of routine physical activity
Management:-
Rx.
Cafergot (migril) : one tablet as soon as after attack , repeat if necessary.
Nursing Care:-
A migraine headache in the early phase requires abortive drug therapy.
Nursing care during a fully developed attack includes comfort measure such as quite, dark
environment.
Stress is believed to be a factor in the precipitation of migraine.
Instruction about the importance of proper diet, adequate rest and coping strategies may
help the patient to deal with stress.
Long intervals between meals also should be avoided.
Women should avoid oral contraceptive.
Proper rest should be advised.

Cerbro-Vascular Accident or Stroke
A stroke is the rapidly developing loss of brain functions due to a disturbance in the blood vessels
supplying blood to the brain. This can be due to ischemia (lack of blood supply) caused by thrombosis
or embolism or due to a hemorrhage. As a result, the affected area of the brain is unable to function,
leading to inability to move one or more limbs on one side of the body, inability to understand or
formulate speech or inability to see one side of the visual field
Classification
Ischemic stroke
In an ischemic stroke, blood supply to part of the brain is decreased, leading to dysfunction of the brain
tissue in that area. There are four reasons why this might happen: thrombosis (obstruction of a blood
vessel by a blood clot forming locally), embolism (idem due to an embolus from elsewhere in the
body,) systemic hypoperfusion (general decrease in blood supply, e.g. in shock)[6] and venous
thrombosis.
Hemorrhagic stroke
Intracranial hemorrhage is the accumulation of blood anywhere within the skull vault. A distinction is
made between intra-axial hemorrhage (blood inside the brain) and extra-axial hemorrhage (blood
inside the skull but outside the brain). Intra-axial hemorrhage is due to intraparenchymal hemorrhage
or intravascular hemorrhage (blood in the vescularcular system).
.Causes of stroke :-
1. Arteriosclerosis & thrombus formation: -
Cerebral arteriosclerosis are major cause of cerebral thrombosis which is the most common
cause of stroke.
2. Cerebral embolism: -
Pathologic abnormalities from myocardial infection or muscloskeletal embolus formation may
cause C.V.A.
3. Cerebral Ischaemia: -
Caused by cerebral athermanous constriction of arteries.
4. Cerebral Hemorrhage: -
subdural hamorrhage.
Subarachnoid hemorrhage.
Intracerebral hemorrhage.
These hemorrhages are caused by skull fracture due to trauma/ accidents or hypertension.
Risk Factors: -
1. Hypertension.
2. cardiovascular disease.
3. elevated cholesterol in blood.
4. obesity
5. Diabetes mellitus.
6. Smoking.
7. oral contraceptives.
8. Fractures.

Pathophysiology: -
Cerebral blood flow is maintained at 750 ml/minute. About 20% of the flow to the brain ensures the
optimal cerebral function. If this is interrupted due to any cause may cause C.V.A. neurologic
metabolism is altered in 30 seconds, metabolism stop in 2 minutes and cellular death occurs in 5
minutes after interrupted blood flow. The interruption of blood occurs due to many cause, these causes
are cerebral Ischaemia and signs and symptoms appear due to neurological defect.
Clinical Features: -
Motor loss
Hemiplegia (paralysis of one side of body).
Hemiparesis (weakness of half body).

Musculo-Skeletal Disorders
Muscular System: -
Muscles are involved in body movement, posture and heat production function. The muscles
are attached by tendons or flat sheet of connective tissue to bone, connective tissue, other
muscles, soft tissue and skin. Muscles vary in size and shape according to their activity.
Muscles of body are composed of parallel groups of muscle cells called Fasciculi encased in
fibrous tissue called epimysium.
Myoglobin is hemoglobin like protein pigment that is present in striated muscle cells. It
transport oxygen for the cells metabolism. Each muscle cell contain myofibrils, composed of
series of Sarcomere; the actual contractile unit of skeletal muscles. Sarcomere is composed of
thin and thick filament Thin filaments are composed of protein called actin & Thick is
composed of myosin.
Skeletal Muscles: -
Contraction of a muscle is due to contraction of each of its component Sarcomere. The
contraction is due to interaction between myosin in thick filament and action acticin in this
filament. Thick and thin filaments slide across one another. when calcium level in sarcomere
falls the myosin and actin fail to interact and sarcomere turns to its original length. Actin and
myosin do not interact in the absence of calcium.
Depolarization normally occurs in the response to stimulus delivered by nerve cell.
The communication between nerve cell and muscle cell takes place at motor end plate. The
neurons that control the activity of muscles are called motor neurons originate in anterior horn
of spinal cord. For muscle contraction energy is required source of energy is A.T.P.
Types Of Muscle Contraction: -
Isometric Isotonic
In this length of muscle remains Contraction of muscles
constant but force generated by characterized by the shortening
muscle is increased. E.g. pushing of muscles with no increase in
against immoveable wall. tension in muscles e.g. walking
Sakhawat Baloch 29
Nursing Instructor SON Male Jacobabad
Medical surgical Nursing-III
Muscle Tone: -
Relaxed muscles demonstrate a state readiness to respond to stimuli. This state of readiness is
called tonus (tone). Muscle that has less tone is called flaccid & muscle with more tone is
called spastic. Absence of tone is called atonic.
SOME TERMS: -
1. Scoliosis: -
Lateral curving deviation of spine.
2. Kyphosis: -
An increased roundness of the thoracic spine curve.
3. Lordosis: -
Sway back, exaggeration of the lumber spine curve.
4. Contracture: -
Shortening of surrounding joint structure.
5. Dislocation: -
Complete separation of the joint structure.
6. Flexion: -
Bending at joint.
7. Extension: -
Strengthening at joint.
8. Abduction: -
Action of moving away from midline of body.
9. Adduction: -
Action of moving towards the midline.
2. Endochondral Ossification: -
In this cartilage model exist cartilage like osteiod is formed, resorbed and replaced by bone.
Most bones in body are formed and heal by endochondral ossification.
Bone Maintenance: -
Bone is maintained by reabsorption and absorption. In this hormones are involved in these
process such as paratharoxone, calcitonin, oestrogen, progesterone etc.
Bone Healing: -
1. Inflammation:
There is bleeding in the injured tissue and formation of fracture hematoma. The injured area is
invaded by macrophages which debride the area.
2. Cellular Proliferation:
Within 5 days fibrin threads form within clot creating network revascularization. Fibroblast
and osteoclast produce collagen for collagen matrix at the fractured area.
3. Callus Formation:
Tissue growth continues and the cartilage collar each bone fragment grows towards the other
until the gap is bridged. The fractured fragments are joined by fibrous tissue, cartilage and
immature bone fiber. It takes 3-4 weeks for fractured fragments to be united by cartilage.
4. Ossification:
The developed callus begins to ossify through process of endochondrial ossification. Minerals
are continuously deposited until bone becomes firm. Long bones take 3-4 months for
ossification.
5. Remodeling:
In this final stage remaining devitalized tissue are removed and recognizing the new bone into
its former structural arrangement. It may takes months to years depend on the bone

Management Of The Patient In a Cast
Cast: -
This is rigid external immobilizing device that is molded to the counters of the body to which it
is applied.
Purpose: -
To immobilize the part in a specific position.
To apply uniform pressure on encased soft tissue.
To correct the deformity.
To provide support and stability for weakened joint.
Types: -
1. Short Arm Cast:
It extends from below the elbow to the palmer crease, secured around the base of thumb. If
thumb is used it is called thumb spica or gauntlet “thumb”
2. Long Arm Cast:
Extends from upper level of axillary’s fold to the proximal palmer crease. Elbow is usually
immobilized at right angle.
3. Short Leg Cast:
Extends from below the knee to the base of the toe.
4. Long Leg Cast:
From upper and middle third of thigh to the base of toe. Knee joint is slightly flexed.
5. Body Cast:

8. Hip Spica Cast:
Enclosed trunk and lower extremity.
Nursing Care Of Patient With Cast: -
1. Assess the cast and remaining area.
2. Evaluate for pain, if occur, indicate skin break down, more pressure, pressure ulcer
etc. most pain can be relieved by elevating the involved area, applying cold as
possible and with analgesics.
3. Unrelieved pain must be reported immediately to the doctor to avoid possible
necrosis and paralysis.
4. Every joint that is not immobilized must be excursed or move through range of
motion.
5. Assess for bluish colour of extremities.
6. Provide firm mattress on bed.
7. Change the position 2 hourly.
8. Maintain adequate tissue perfusion.

Traction:
Traction is the application of a pulling force to a part of the body to minimize muscle spasm
and maintain the position of effected part.
Purpose:
To minimize the muscle spasm.
To immobilized the body part.
To reduce and align the fractures
To reduce the risk of deformity.
To treat the dislocation.
To attain equilibrium.
Principles of Effective Traction:
Whenever traction is applied the counteraction must be considered. Counteraction is the force
that acts in the opposite direction (Newton’s 3rd law). Patient’s body weight and bed position
adjustment supply the needed counteraction.
Any factor that reduces the pull, must be eliminated.
Patient is in good body alignment in the center of bed when traction is applied.
Ropes must be unobstructed.
Weights must hang freely not rest on bed or floor.
Knots of rope must not touch the pully.

Fractures
The break down in the continuity of the bone mainly occurs when the bone is subjected to
stress which it can not bear. The highest incidence of fracture is seen in male 15-24 years old
and in elderly women aged 65 years or more.
Causes:
1. Crushing force.
2. Accident
3. Twisting motion.
4. Extreme muscular contraction.
5. Osteoporosis etc.
Types:
1. Complete Fracture:
Fracture involves a break occurs the entire cross section of the bone and is frequently displaced
(remove from normal position).
2. Incomplete Fracture:
The break occurs through only part of the cross section of the bone.
3. Closed Fracture/Simple Fracture:
Fracture does not produce break in skin.
4. Open Fracture/Compound Fracture:
Type of fracture in which skin & mucus membrane wound extends to the fractured bone. Open
fracture is graded on Grade I= Clean wound less than 1 cm Grade II= Large wound without
extensive soft tissue damage Grade III= Highly contaminated wound with damage of soft
tissue.
Other Specific Types are:
1. Green Stick: fracture and in which one side of bone is broken and other side is bent.
2. Transverse: Fracture that is straight across the bone.
3. Oblique: Fracture that occurs at an angle across the bone.
4. Spiral: Fracture twisting around the shaft of the bone
5. Communited: Fracture in which bone is broken unto several fragments.
6. Depressed: Bone fragments are driven inward (e.g. in skull and facial bone)
7. Epiphyoeal: Fracture through the epiphyseal.
8. Impacted: Fracture in which bone fragment is driven into an other bone fragment.
9. Pathological: Fracture of diseased bone e.g. osteoporosis, peget’s disease.
10. Avulsion: Fracture of bone that occurs due to the pull of the tendon or ligameny.
Clinical Features:
1. Severe pain, which is continuous until bone is immobilized
2. False or unnatural motion .
3. Deformity
4. Shortening of extremity.
5. Grating sensation when touched (crepitus).
6. Localized swelling & edema.
7. Skin discoloration.
Sakhawat Baloch 35
Nursing Instructor SON Male Jacobabad
Medical surgical Nursing-III
Emergency Management:
When fracture is suspected it is most important to immobilize that body part immediately
before patient is moved to hospital.
If patient is removed from vehicle before splint can be applied, the extremity is supported
above & below the fractured site to prevent rotation as well movement of effected part.
The pain is severe, it can be relieved by preventing movement of fractured part.
Appropriate splint are essential to prevent tissue damage.
The injured area can be immobilized by applying temporary well padded splint, which then
bandage firmly.
In open fracture cover the wound with clean sterile dressing to prevent contamination.
No attempt is made to reduce the fracture, even if fragment protrude from injury.
Patient’s clothes may be cut away from site and is fracture is reduced by trained surgeon in
O.T.
Principles Of Managing Fracture:
1. Fracture Reduction:
Reduction of fracture (“setting the bone”) refers to restoration of the fracture fragments into the
anatomic alignment and rotation.
In closed reduction bone fragments are brought into apposition(ends in contact) by
manipulating and manual traction.
Open reduction requires open surgery internal fixation devices in the form of metallic pins,
wires, screw, slates, nails or rods may be used to hold the bone fragments in the position.
2. Fracture Immobilization:
After fracture reduction bone fragments must be immobilized or held in correct position.
Immobilized bone may be accomplished by external or internal fixation. External fixation
include cast, splint, bandage etc.
3. Maintaining The Function:
Efforts should be taken to maintain the function.
4. Restoring The Function:
Assessment for neurovascular status. Involvement of patient in self-care etc

Contusions strains& sprains
Contusion:
This is an injury of the soft tissue produced by the blunt force (e.g. a kick, fall etc). The
resultant rupture of many vessels lead to bleeding into soft tissue ( Ecchymosis, bruising). The
local symptoms are pain, swelling and discoloration. Most of them are resolve in 1-2 weeks.
Strain:
This is muscle pull due to over use, over stretching or excessive stress. Patient experience local
tenderness upon the muscle use and isometeric contraction.
Sprain:
It is an injury to ligamentous structured surrounding the joint caused by twisting motion. The
joint becomes tender and movement is limited. .
Treatment of contusion, sprain & strain consists of resting and elevation of effected part and
applying cold and using a compression bandage. Cold should be applied intermittently for 20-
30 minutes during first 24-48 hours. Cast is necessary if joint is unable to perform function.
After 48 hours injury heat may be applied to reduce muscle spasm and promote vasodilation,
absorption & repair.
Excessive exercise should be avoided, these may lead to severe tissue damage. Strain & sprain
may take weeks to months for healing.
Painkiller may be used to reduce pain, swelling etc.
Antibiotic may be used to prevent from secondary infection.
Joint Dislocation:
A dislocation of a joint is a condition in which the articular surface of the bones forming the
joint are no longer in anatomic contact. The bones are literally “out of joint”.
Dislocation may be congenital (present at birth), spontaneous (pathologic) & traumatic.
The signs and symptoms are pain, change in conteur of joint, change in length of extremity,
loss of normal mobility. X-rays confirm the diagnose.
Management:
The affected joint needs immobilization.
The dislocation is reduced (i.e. displaced parts are brought in normal position).
The head of dislocated bone is brought on the cavity of other bone.
The joint is immobilized by splint or cast.
Analgesic to control the pain
Antibiotic to control any infection etc.

PAGET’S DISEASE (OSTEITIS DEFORMAN)
Paget's disease, also known as osteitis deformans, is a chronic disorder that typically
results in enlarged and deformed bones. It is named after Sir James Paget, the British
surgeon who first described this disease the excessive breakdown and formation of bone
tissue that occurs with Paget's disease can cause bone to weaken, resulting in bone pain,
arthritis, deformities, and fractures.
This is localized increase bone remodeling most commonly affecting the skull, femur,
tibia, pelvis bone and also vertebrae. There is primarily resorption of the bone followed
by compensatory increased in osteoblast activity (bone repair). The bone formed is high
in mineral content but poorly constructed. The bones are weak and pathological
fractures occur. Frequently the bone bow. This is genetically occurring in patients.
Clinical Features: -
Cortical thickness
Enlarged head Skull may be thickened and complains hat no longer fits.
Femur and tibia tend to bow.
Chin rests on chest.
Arms are bent outward & forward.

GOUT/GOUTY ARTHRITIS
This is heterogeneous group of conditions related to genetic defect characterized by hyper
urecemia, recurrent attack of arthritis. This is caused by either over secretion of uric and/or
impaired excretion of uric and through kidneys.
Pathophysiology:-
Hyper urecemia can cause urate crystals deposition. The attack of gravity arthritis is caused by
sudden increase or decrease of serum uric acid levels. When the urate crystal precipitate with
in a joint and inflammatory response occur and attack of gravity occur with repeated attack,
accumulation of sodium urate crystal called “Tophi” are deposited in peripheral part of body is
toes, hands etc.

AMPUTATION
Amputation means removal of limb or its part or other appendages of body Amputation of lower
extremity is often necessary as a result of progressive peripheral vascular disease such as sequela of
diabetes Mellitus, gangrene, trauma, burns, electrical burns, malignant tumors. Of all these causes
peripheral vascular diseases account for majority of amputation of lower extremity. The major reasons
for upper extremity amputation are severe trauma, malignant tumor, infection, and gas gangrene.
The purposes of amputation are:
1. To relieve the symptoms.
2. To control the infection (gangrene).
3. To improve the function.
4. Save the patient’s quality of life.
Factors Effecting Amputation: -
Age: -
Patient who require amputation are usually either young with severe extremity trauma or elderly with
peripheral vascular disease. The young are usually health and heal rapidly.
Pathological condition of above:
e.g. osteoporosis.
Chronic progressive disorders:
e.g. Diabetes Mellitus, Hypertension.
Cardiovascular disorder.
Respiratory disorder.
Level of Amputation
Amputation is performed at the most distal point that will heal successfully. Site of amputation
determined by two factors 1. Circulation in the part 2. Functional usefulness. The most appropriate site
for amputation are:
Below the knees amputation.
Above the knee amputation.
Amputation of foot and ankle (Symes).
Amputation of foot between metatarsus and tarsus (Hey’s).
Hip disarticulation removal of limb from hip joint.
Nursing Care: -
Assess the amputation and monitor drainage for color and amount.
Position of the patient with no flexion of hip or knee.
Relieve the pain by administering of analgesic.

ATOPIC DERMATITIS (ECZEMA)
It is atopic, hereditary, and non-contagious skin disease characterized by chronic inflammation
of the skin. Major features include pruritis (itching) a typical morphology and distribution and
a personal or family history of atopy (asthma, hay fever, and atopic dermatitis)
Pathophysiology: -
It involves immunological abnormalities, such as elevated immunoglobulin E levels and
increased rates sensitization to common contact allergens and intradermal test. Almost 75%
of patient with this form eczema have a family history of atopic dermatitis, hay fever, or
asthma.
Clinical Features: -
It is divided into three stages based on clinical appearance of the lesions.
1. Acute : Moderate to intense erythema, vesicles, a wet surface and severe itching.
2. Subacute: Erythema and scaling present in various patterns with indistinct borders.
Irritation, allergy, or infection can convert a subacute process into and acute one.
3. Chronic: The inflamed area thickens and the surface skin markings become more
prominent. Lichenification is the hallmark of chronic eczema. The surface of the skin is
dry and the border of the lesion well defined. There is moderate to intense itching.
Diagnostic Evaluation: -
1. Clinical diagnosis based on evaluation of the aggregate of signs, symptoms, course,
and associated familial findings.
2. Skin biopsy may be performed if clinical finding are in doubt.
Management: -
1. Topical:
A. Acute & weeping Lesions: -
Use saline solution for washing.
Use steroid in the form of cream instead of lotion.
B. Subcutaneous/Scaly lesion: -
The steroids are used in the form of ointment.
C. Chronic/Lichenification lesions: -
They are best treated with ointment.

2. Systematic:
Cortisone (predisone 40-60 mg daily)
Nursing Care: -
As atopic people are sensitive to low humidity and often get worse in winter.
Simple soap should be used avoid wash cloth & brushes to the effected part.
Avoid dry soap for bathing.
After bathing skin should be patted dry (not rubbed).
Immediate cover the effected site part with thin film of emollient such as Vaseline,
very hot bathes may increase itching so avoid from hot bathing.
Advanton (methyl predisolon) cream & ointment.
Dermovate (Clesbestasol) cream & ointment.
Betnovate (Belimethasone) cream & ointment.
CONTACT DERMATITIS
Contact dermatitis is inflammation of the skin caused by exposure to external agents which
may affect various parts of the body.
Irritant contact dermatitis can occur in any person or contact with a sufficient
concentration of the irritant. Irritants include wool, glass, fibers, acid, alkaline, solvents,
detergents, oils found in clearing compounds, urine, feces, toxins from insects or aquatic plants
etc…
Allergic Contact dermatitis is cell-mediated hypersensitivity immune reaction from contact
with a specific antigen. Antigens include poison, ivy, synthetics, industrial chemicals, drugs
etc..
Clinical Manifestations: -
1. Itching, burning, erythema and vesiculation at point of contact.
2. Progression to weeping, crushing, drying, fissuring and peeling.
3. Lichenification (thickening of skin and pigmentation changes may occur with
chronicity.
Management: -
Topical or oral steroids.
Removal or avoidance of causative agents.
Antipruritis systemic or topical antihistamines.
Desensitization to poison or other substance
Nursing Consideration: -
1. Take through history to determine causative agents or contribution factors.
2. Teach patient to use allergen free products, wear gloves and protective clothing.
Wash and rinse skin thoroughly and wash clothing after contact.

PSORIASIS
This is the hereditary non-infectious inflammatory disease of the skin in which abnormal
production of epidermal cells characterized by silvery scales mostly effects the elbow, fingers,
knee, abdomen, back etc. The production of epidermal cells occurs at a rate that is
approximately six to nine times faster than normal. The cells in the basal layer of the skin
divide too quickly and the newly formed cell move rapidly to the skin surface, that may
become evident as profuse scale of epidermal tissue.
Causes: -
The disease stems from a hereditary defect that causes over-production of keratin. But the
actual cause is still unknown.
Signs and Symptoms: -
Red, raised plaques of skin covered with silvery scale.
Plaques usually arises on the knees, elbow and scalp.
If nails are involved, the nail findings are pitting with onycholysis.
Mild itching
Diagnosis: -
Plaque like lesions mostly confirm the diagnosis.
Management: -
Polytar (purified coaltar) liquid.
Casoderm (Antipsoriatic/steroid) ointment.
Daivonex/Dovonex (calcipetriol).
Nursing Care: -
The nurse explains with sensitivity that currently there is no treatment of psoriasis
and life time management is essential to control the severity of disease.
Educate the patient that minor injuries, cuts, stress, sun burn, infections can
exacerbate the disease.
Advice the patient not to scratch or pick the effected area.
Measures should be taken to prevent from skin dryness.
Too frequent washing may cause soreness and scaling.
Skin should be dried by patting, not by rubbing.
Emollient should be applied for moisturizing.
Instruct the patient not expose the area in sunlight.
BURN
Sakhawat Baloch 53
Nursing Instructor SON Male Jacobabad
Medical surgical Nursing-III
Transfer of energy causes burns from a heat source to a body. Heat may be transfer through
conduction or electromagnetic radiations. There are three main types of burn i.e. thermal,
radiation and chemical.
The depth of burn injury depends upon the temperature of the burner agent and the duration of
contact with agents.
Cardiovascular Response: -
A fluid loss continues and vascular volume decrease, cardiac continues to fall and blood
pressure drop. This is the onset of burn shock. In response the sympathetic nervous system
release chatecholamine, it causes peripheral vasoconstriction, further decrease cardiac output.
Effects on fluid Electrolytes: -
Due to burn, the body fluid is decreased, sodium level is also reduced.
Degrees of Burn: -
1. Superficial (First Degree): -
In this only epidermis is involved. E.g. sun burn & low intensity flash.
2. Partial-Thickness (Secondary Degree): -
In this the epidermis & part of dermis is involved e.g. scald & flesh flame.
3. Full-Thickness (Third Degree): -
In this degree, the epidermis, entire dermis & sometimes subcutaneous tissue involves.
E.g. flame, prolonged exposure & hot electric current.

HERPES SIMPLEX
It is a viral acute vesicular eruption caused by herpes simplex virus type 1 and 2. Type 1
caused cold sores or fever blisters – an eruption of blisters that often occurs during the course
of or after one of a variety of disease associated with fever (most commonly colds, influenza,
and pneumonia). The blisters usually appear around the mouth and on the lips (herpes
labialise); about the nose, face, and ears and in the mouth & pharynx.
The second type of herpes simplex virus is the usual cause of genital herpes {sexual
transmitted infection}.
Clinical Manifestaions: -
1. Prodormal pain, burning or tingling possible fever malaise.
2. Tiny vesicles appear on erythematous, swollen base; they rupture forming painful
ulcers, crushing, and eventually healing.
3. Can occur anywhere, especially the mucocutaneous junctions.
4. Vial shedding may occur between symptomatic period, leading to transmission of
infection.
Complications: -
1. Eczema Herpetium.
2. Herpetic whitlow (infection of the pulp of the fingertip with herpes type 1 & 2.
3. Neonatal infections occur during delivery by contact of infant with mother’s active
ulceration. Fetal anomalies include skin lesions, microcephaly, encephalitis.
Diagnostic Evaluation: -
1. Tranck smear
2. vial culture.
Management: -
1. Antiviral treatment with Acyclovir, famciclovir and valciclovir.
2. Analgesic
Nursing Care: -
1. Teach patient that it can transmitted by close and sexual contact, good hygiene and
hand washing are required, sexual abstinence or use of condom.
2. Recurrence may be brought by illness, emotional stress, pregnancy, sunlight and
other factors.
3. Advice patient with active herpes simples infection to avoid contact with
immunosupressed individuals because herpes simplex infection can be severe in these
individuals.
4. Tell patient that the lesions resolve in 1-2 weeks without scarring.

SCABIES
Skin disease caused by a tiny parasite called an itch mite which burrows into the epidermis.
Scabies causes severe itching and is highly contagious. Itch mites are usually spread by close
skin-to-skin contact with an infected person. Sexual contact is an other means of transmission.
The itch mite that most commonly causes scabies is the female of the species Sarcoptes
scabiei.
Clinical Manifestaitons: -
It attacks about 4 weeks from time of contact for the patient’s symptoms to manifest
1. Itching, more intense at night.
2. Small erythematous papules and short, wavy burrow are seen on skin surfaces.
3. Frequently seen between fingers and groin area.
4. Spares head and scalp, except in children under 1 year of age.
Diagnostic Assessment: -
Parasite identifies by microscopic examination of skin scraping.
Management: -
1. Treated with anti-parasitic such as lindance, permethrin or crotamiton & Benzyl
benzonate.
2. Machine wash & dry clothing and linens on hot cycle.
3. Topical or systematic steroids may be needed to symptoms of allergic reactions of
scabies.
Nursing Considerations: -
1. Teach proper use of medication.
2. Advice patient to avoid close contact for 24 hours after treatment to prevent
transmission..
3. Tell the patient that itching may persist for days to weeks following treatment.

ENDOCRINE SYSTEM
Health History: -
During the health history, patient asked for fatigue and changes in usual
fatigue and energy level.
The patient is asked about in heat and cold tolerance.
Recent changes in weight increased or decreased may occur in adrenal and
thyroid disorders.
Changes in sexual functions and secondary sex characteristic may occur in
with any number if endocrine disorder.
Changes in mood, memory and sleep.
Physical Assessment: -
Patient is observed for obvious changes in appearance that may indicate endocrine dysfunction for
example changes in skin are common with both hypo function and hyper function of thyroid gland.
Eye change may occur in with exopthamos of hyperthyroidism and graves disease. Changes in
physical appearance i.e. appearance of facial hair in women, moon face, buffalo hump, thinning of
skin, obesity of trunk and thinness of extremities, increased size of feet and hands, edema.
Vital sign are measured in physical assessment. Hypertension may occur with hyper function of
adrenal cortex or tumor of adrenal medulla. Hypotension may occur in hypo function of the adrenal
cortex. Tachycardia may be noticed.
Radioactive Iodine Therapy: -
The goal of the treatment with radioactive Iodine (123I or 131 I) is to destroy the over thyroid cells. Use
of radioactive iodine is most common treatment in elderly patients. Almost all the iodine that enters
and is retained in the body becomes concentrated in thyroid gland. Radioactive isotope of iodine is
concentrated in thyroid gland, where it destroys thyroid cells. In radioactive therapy a single oral dose
of agent (Radioactive iodine 123 I or 131 I) is administered by the radiologist.
Dose is based on 80-160 uG/g estimated thyroid weight. About 70% to 85% of the patients are cured
by one dose of radioactive iodine.
An additional 10% to 20% require two doses, rarely third dose necessary.
Radioactive has been used in toxic adenomas and multinodular goiter and thyrotoxicosis. A major
advantage of use of radioactive iodine is that it avoids may of side effects.

CUSHING’S SYNDROME
Hypersecretion of cortical hormones from adrenal cortex from adrenal gland. It is opposite of
the addisons disease.
Causes: -
Excessive administration of cortisone.
Hyperlapsia of adrenal gland.
Pathophysiology: -
The basic lesions responsible for Cushing’s syndrome may be the tumor of the pituitary gland
that produces ACTH and stimulates the adrenal cortex to increase the hormones secretion
despite the adequate amount being produced. Primary hyperlapsia of adrenal gland of pituitary
gland is less common.
Administration of cortisone or ACTH may produce Cushing’s syndrome.
Clinical Features: -
Obesity with a fatty “buffalo hump”

Pre-operative Management: -
1. Pharmacotherapy: -
Before undergoing surgery for treatment of hyperthyroidism, the patient is treated with
appropriate medication to return the thyroid hormone level and metabolic rate to normal and to
reduce the risk of thyroid storm and hemorrhage during post-operative period.
Stop prolong cotting medications i.e. asprin before several weeks to surgery to
minimize the risk of post-operative bleeding.
2. Reduce Anxiety: -
One important approach in pre-operative period is to gain the confidence of the patient and
reduce anxiety.
3. Supplement of vitamins particularly thiamine and ascorbid acid are provided.
4. Tea, coffee, cola, and other stimulant are avoided.
Pre-operative Preparation: -

Special efforts are made to ensure a good night rest preceding surgery.
Take the consent from the patient or their relatives.
Give O.T. dress.
Patient education: Pre-operative teaching includes demonstrating to the patient how to
support the neck with hands after surgery to prevent stress on the incision.
Post-operative Management: -
Patient is moved and turned carefully to support the head and avoid tension on
sutures.
Provide most comfortable position, semi-fowlers position with head elevated and
supported by pillows.
Analgesic are administered as prescribed for pain.
