sensory and speciual senses
motor funtion
67. AURA
(flashing light, smells, spots before eyes,dizziness)
TONIC – CLONIC PHASE
Tonic phase- contraction
Clonic phase – jerking movements
Accompanied by dyspnea, drooling of saliva, urinary continence
POST-ICTAL PHASE

naked public, running
70. STATUS EPILEPTICUS
(ACUTE PROLONGED SEIZURE ACTIVITY)
IS A SERIES OF GENERALIZED SEIZURE THAT
OCCUR WITHOUT FULL RECOVERY OF
CONSCIOUSNESS BETWEEN ATTACKS
THE TERM HAS BEEN BROADENED TO INCLUDE
CONTINUOUS CLINICAL OR ELECTRICAL SEIZURES
LASTING AT LEAST 30 MINUTES, EVEN WITHOUT
IMPAIRMENT OF CONSCIOUSNESS.
A seizure is a sudden disruption of the brain's normal
electrical activity, which can cause a loss of
consciousness and make the body twitch and jerk. This
condition is a medical emergency.
71. CAUSES
not taking anticonvulsant medication
also caused by an underlying condition, such as
meningitis, sepsis, encephalitis, brain
tumor, head trauma, extremely high fever, low
glucose levels, or exposure to toxins.
72. Symptoms
The characteristic symptom of status
epilepticus is seizures occurring so frequently that they
appear to be one continuous seizure. These seizures
include severe muscle contractions and difficulty
breathing. Permanent damage can occur to the brain and
heart if treatment is not immediate. A person's
symptoms can range from simply appearing dazed to the
more serious muscle contractions, spasms, and loss of
consciousness. The specific symptoms depend on the
underlying type of seizure.
73. TWO CATEGORIES OF STATUS EPILEPTICUS
CONVULSIVE
Epilepsia partialis continua is a variant it involve an hour, day
or even week-long jerking. It is a consequence of vascular
disease, tumor or encepalitis and drug resistant.
NONCONVULSIVE
Complex Partial Status Epilepticus CPSE and absence status
epilepticus are rare forms of the condition which are marked
by nonconvulsive seizures. In the case of CPSE, the seizure is
confined to a small area of the brain, normally the temporal
lobe. But the latter, absence status epilepticus, is marked by a
generalised seizure affecting the whole brain, and an EEG is
needed to differentiate between the two conditions. This
results in episodes characterized by a long-lasting stupor,
staring and unresponsiveness.
74. HOW IT IS DIAGNOSED?
Status epilepticus is diagnosed according to its
characteristics symptoms. The doctor will order test to
look for the cause of the seizures. This may include
blood test
ECG to check for an abnormal heart rhythm
EEG to check electrical activity in the brain
MRI or CT scan to check for braing tumord or
signs of damage to the brain tissue.
75. Nursing Diagnosis
High Risk for Injury r/t Seizure
Activity
Individual Coping r/t perceive
social stigma, potential changes
in employment
76. MEDICATIONS
diazepam (Valium)
this will stop motor movement
Phenytoin (Dilatin)
Phenobarbital (Barbita)
Paraldehyde
Thiopentahl sodium (Pentotal sodium)
General anesthesia may also be used as a treatment of last
resort to stop seizure activity
77. NURSING INTERVENTION
PREVENTING INJURY
REDUCING FEARS OF SEIZURE
IMPROVING COPING MECHANISMS
PROVIDING PATIENT AND FAMILY EDUCATION
MONITORING AND MANAGING POTENTIAL COMPLICATIONS
TEACHING PATIENTS SELF-CARE
78. PREVENTING INJURY
injury prevention for the patient with seizure is a PRIORITY.
patient should be placed on the floor and remove any obstructive
items
patient should never be forced into a position
pad side rails
do not attempt to pry open jaws that are clenched in a spasm to
insert anything.
if possible place the patient on one side with head flexed forward,
79. PATIENT
EDUCACTION
TAKE MEDICATION AT REGULAR
BASIS
AVOID ALCOHOL. Lowers seizure
threshold
ADEQUATE REST
WELL-BALANCED DIET
AVOID DRIVING, OPERATING
MACHINES, SWIMMING UNTIL SEIZURES
ARE WELL CONTROLLED.
LIVE AN ACTIVE LIFE
80. REDUCING FEARS OF SEIZURE
Fear that a seizure may occur unexpectedly
can be reduced by the patients adherence to
the prescribed treatment regimen.
Cooperation of the patient and family and
their trust in the prescribed regimen are
essential for control of seizures
Periodic monitoring is necessary to ensure
the adequacy of the treatment regimen and
to prevent the side effects.
back
81. IMPROVING COPING MECHANISMS
it has been noted that the social,
psychological, and behavioral problems
frequently accompanying the attack can be
more handicap than the actual seizure.
Counselling assists the individual and family to
understand the condition and the limitations
imposed by it. Social and recreational
opportunities are good for mental health .
Nurses can improve the quality of life for
patients with the disorder by educating them
and their family about the symptom and also
the management.
82. PROVIDING PATIENT AND
FAMILY EDUCATION
Ongoing education and encouragement
should be given to patients to enable them to
overcome these feelings. The patient and
family should be educated about the
medications as well as care during a seizure.
perhaps the most valuable facets are
education and efforts to modify the
attitudes of the patient and family toward
the disorder.
83. MONITORING AND MANAGING
POTENTIAL COMPLICATIONS
Patients should have plan to have
serum drug levels drawn at regular
intervals. The patient and family are
instructed about the side effects and
are given specific guidelines to
assess and report signs and
symptoms indicating medication
overdose.
84. TEACHING PATIENTS SELF CARE
Like thorough oral hygiene after each
meal, gum massage, daily flossing, and
regular dental care
The patient is also instructed to inform
all health care providers of the
medication being taken because of the
possibility of drug interactions. An
individualized comprehensive teaching
plan is needed to assist the patient and
family to adjust to this chronic disorder.

100. Emergency Care
• First consideration is to ensure a clear airway
• Keep spine straight; patient is carefully turned
to a lateral or semiprone position
• Flexion or hypertension should be avoided in
case there is a cervical fracture
• Keep patient covered, quiet and undistrubed
101. General Care:
• Establish airway
• Prevent aspiration pneumonia
• Check for cardiovascular complications
• Serach for new evidence of spinal injuries. Do not allow
the newly injured patient to move about even though
he/she is conscious.
• Observe the skull and scalp injuries. cover open head
wound with the cleanest material avaialble at the
scene
• Prevent infection. Gove prophylactic dose for tetanus.
102. General Care (Cont)
• Observe for CSF leakage –
otorrhea, rhinorrhea, Battle’s sign-tenderness
and eccymosis or mastoid bone especially for
basilar skull fracture
• Obeserve for signs and symptoms of increased
ICP; watch for nuclear rigidity.
• Control restlessness and pain. Narcotics are
contraindicated following head injury, and are not
given if ICP is prevent.
• Maintain fluid/electrolyte; acid-base balance and
adequate nutrition. Record I & O.
104. Management of ICP
• Control Fever
– Fever increases cerebral metabolism and
edema
- Antipyretics, cooling blanket
- Avoid shivering which increases ICP
Reduce metabolic demands
– Barbiturates decrease ICP
- Muscle relaxants to paralyze patient
105. Ineffective airway clearance related
to accumulation of secretions and
decreased LOC
• Maintain patient airway
– Suction carefully
- Discourage coughing (causes increase in ICP)
- Elevate HOB 30 degrees
- Guard against aspiration
- Monitor ABGs to assess ventilation
106. Ineffective breathing pattern related
to neurological dysfunction
•
Monitor constantly for respiratory
irregularities
– Cheyne Stokes, hyperventilation,
Effective suctioning
HOB 30 degrees
Position patient lateral or semi prone
107. Altered cerebral tissue perfusion
related to increased intracranial
pressure
• Position patient to reduce ICP :
– head in midline position to promote venous
drainage
- Elevate HOB 30 degrees
- Avoid extreme rotation or flexion of neck
- Avoid extreme hip flexion
108. • Prevent straining
- Stool Softeners
- High Fibre diet
Space Nursing activities
Maintain calm atmosphere, reduce stimuli
109. Risk for fluid volume deficit related to
dehydration procedures and
decreased LOC
Monitor electrolytes
- Brain damage can produce metabolic and
hormonal dysfunctions
Monitor intake and output
Monitor IV fluids carefully
Monitor urine for acetone, osmolality
Record daily weights
110. Altered nutrition related to metabolic
changes, inadequate intake.
• Start enteral feedings when patient stabilized
- NG feeding unless CSF rhinorrhea
- Elevate HOB 30 degrees
- Aspirate for residual before feeding to
prevent distention and aspiration
- Use pump to regulate feeds
111. Risk for injury related to
disorientation, restlessness and brain
damage.
•
Assess for cause of restlessness
- Often present as patient emerges from coma
- May be due to hypoxia, fever, pain, full bladder
Use padded side rails or wrap hands in mitts
- Avoid restraints as straining against them increases
ICP
Minimize environmental stimuli
- Low lights, limit visitors, speak calmly
- Orient patient frequently
112. Risk for altered body temperature
related to damage to temperature -
regulating mechanism
•
Monitor temperature every 4 hrs.
- Can be increased as result of:
Damage to hypothalmus
Cerebral irritation from hemorrhage
Infection
Reduce temperature with acetaminophen and cooling
blankets
If infection suspected –
- Culture potential sites
- Start antibiotics
113. Potential for impaired skin integrity
related to bed
rest, immobility, unconsciousness
•
Assess all body surfaces every 8 hrs.
Turn every 2-4 hrs
Provide skincare every 4 hrs
Assist patient to chair (if possible)
114.
115. Spinal cord injuries:
• cause myelopathy or damage to nerve roots or
myelinated fiber tracts that carry signals to and
from the brain.
• Depending on its classification and severity, this
type of traumatic injury could also damage the
gray matter in the central part of the
cord, causing segmental losses of interneurons
and motorneurons.
116. • Primary prevention important.
– Drive slow, use seat belts &
helmets, water safety, protective devices for
athletes, prevent falls.
117. Assessment
Clinical manifestations depend on type and level of injury
– Below level of injury there is total loss of sensory and motor
paralysis, loss of bladder and bowel control, loss of sweating and
vasomotor tone.
– Complains of acute pain in back or neck which may radiate along
involved nerve.
– Respiratory problems (T1-T11 and diaphragm are used in breathing)
– intercostal muscles.
– above C4 – phrenic nerve – paralysis of diaphragm.
118. • Respiratory status
– observe respiratory pattern, strength of
cough, auscultate lungs.
• Changes in motor or sensory function
– Squeeze hand, spread fingers, move toes.
– Pricking skin with dull item, start at
shoulders.
119. Signs of spinal shock
•
– Complete loss of all
reflexes, motor, sensory and autonomic below
level of injury.
120. Management of Spinal Cord Injuries
• High dose corticosteroids within 8 hrs of injury
– Methylprednisolone, loading dose followed by
infusion for 23 hrs.
• Oxygen, intubation if necessary
• Skeletal reduction and traction
– Immediate immobilization
– Reduction of dislocations (restore to normal
position)
– Stabilization of vertebral column.
– Traction used in cervical fractures.
• Surgery.
121. Nursing Interventions
• Promote adequate breathing and airway clearance.
– Monitor pulse oximetry, ABGs.
– Clear bronchial and pharyngeal secretions
– Use suctioning cautiously – can stimulate vagus
nerve causing bradycardia.
- Chest Physiotherapy, breathing exercises.
– Humidification.
– Adequate hydration.
– Assess for signs of respiratory infection.
– Intubate and ventilate.
122. Improve Mobility
• Maintain proper alignment at all times.
• Reposition frequently.
• Prevent foot drop – wear shoes.
• Prevent external rotation of hip joints – trochanter
rolls.
• Prevent contractures – range of motion exercises 4
times daily.
• If injury above midthoracic level, monitor BP when
turning (loss of sympathetic control of peripheral
vasoconstriction).
123. Maintain Urinary and Bowel Function
• Intermittent or indwelling catheter to avoid
overdistention of bladder.
– Urinary retention results from bladder becoming
atonic.
• Intake and output.
• Insert NG tube to relieve distention and prevent
aspiration.
– Paralytic ileus usually develops.
– Bowel activity usually returns within 1 week.
• High fibre, high protein diet.
• Stool softener.
124. Managing Potential Complications
• Thrombophlebitis and pulmonary embolism
– Assess for symptoms (chest pain, dyspnea, ABGs)
– Measure circumference of thighs and calves daily
– Anticoagulation – low dose heparin
– Pressure stockings.
– Adequate hydration
• Orthostatic Hypotension
– BP unstable and low for first 2 weeks.
– Monitor closely when repositioning patient.
– Reposition slowly, wear pressure stockings.
