Increased ICP Potential complication in many neurological conditions,Often occurs suddenly and progresses rapidly,
Causes of increased ICP Space occupying lesions (tumors),Trauma,CSF excess (due to tumor or inability to drain),Cerebral Edema (due to tumor, trauma, hypoxia)
ICP (IICP) As pressure increases compensation occurs,Venous compression & displacement of CSF,Increased pressure = reduced cerebral blood flow,Increased pressure = reduced cerebral blood flow
Increased ICP (IICP) Increased Edema leads to increase in ICP,Further decrease in CBF= vicious cycle,Supratentorial Shift
Increased ICP (IICP) Herniation-Compression of Vasomotor center=BP, HR,Resp,Temperature control,Oculomotor nerve,Compression of RAS,Corticospinal nerve pathway,DEATH
Clinical Manifestations of IICP Imparitive that detection occur early while still reversible,Deterioration of LOC –(earliest sign)Pupillary dysfunction-ipsilaterat ,Visual Abnormalities Head Aache,Loss of motor function –late signs Alteration in blood pressure, pulse, resp

(IICP)Pain Management and Sedation Analgesics,Sedation reduces brain activity
Analgesics-IICP Treatments Morphine OR Fentanyl (short-acting agent)
Sedation reduces brain activity Usually wake patients up every 24 hours to assess neuro function for first few days after injury,Propofol (very short-acting agent),Midazolam (longer acting agent)
Phenytoin-IICP Treatments Maintain therapeutic dose for 7-10 days after injury to prevent seizures
Seizure-IICP Treatments significantly increase brain metabolism
Paralytic agents IICP Treatments ensure that patient receives adequate sedation and analgesics,Nothing is worse than being awake and paralyzed.=Vecuronium/Atracurium
Mechanical IICP Treatments. Craniotomy Bone flap removed and replaced (for example, removal of a tumor) Craniectomy Bone flap removed and not replaced (often used in trauma to allow brain to swell out of hole)
IICP Treatments Adjunct Endotracheal Intubation-Hypoxia produces cerebral vasoconstriction and is, therefore, avoided,PaO2 around 100mmHg. Hypercarbia (elevated PaCO2) causes cerebral vasodilatation. PCO2 within normal range
IICP Nursing Management Goals=Maintain cerebral perfusion,Prevent further neurologic ischemia
IICP Nursing Management Elevate HOB 30 – 45 degrees,Prevent hyperextension, flexion or rotation of head  Avoid flexion of the hips, waist, and neck Limit suctioning to 15 sec (hyperoxygenate before and after suctioning)Avoid valsalva
IICP Nursing Management Administration of pharmacological therapies Patient response to nursing interventions (particularly ICP) Neuro exams Emotional support Restrict fluids as ordered Foley Temperature control measures (MUST avoid shivering)
The goal of medical and nursing intervention on the IICP patient is To control ICP and protect the brain from secondary injury.

Ischemic Stroke Thrombi usually occur in larger vessels Associated with damage to vessel wall Readily develop when atherosclerotic plaques have narrowed vessel,Internal carotid arteries are common source
Ischemic Stroke Symptoms occur during sleep or soon after rising,S/S frequently worsen for the first few hours post stroke,typically peak within 72 hrs as edema increases in the affected area
Ischemic Stroke Embolic stroke is the 2nd most common cause of stroke Emboli usually originates from a thrombus in the endocardium cause by Rheumatic heart disease, Mitral stenosis, Atrial Fibrillation, MI, valvular prostheses or infective endocarditis. Less common
Embolic Stroke Embolus travels upward into cerebral Circulation & lodges in a bifurcation or Where the vessel narrows. Most often in the midcerebral artery
Hemorrhagic Strokes Account for 15% of all strokes Intracerebral-bleeding into the brain tissue Intracranial-bleeding into the subarachnoid space. Third most common cause of strokes Common causes of hemorrhagic strokes Hemorrhagic disease (leukemia, aplastic anemia)
Aneurysm Localized dilation of the wall of a blood vessel usually caused by atherosclerosis or HTN. Less often causes, Trauma, Infection, Congenital weakness in vessel
Aneurysm Vessel wall progressively weakens until it ruptures. Bleeding usually stops when fibrin & platelet plug forms
Aneurysm Begins to absorb within 3 weeks. High risk for recurrent rupture 7-10 days after initial bleed. Prognosis is poor -50% mortality. No forewarning. Peak incidence in the 35 to 60 year age group. More frequently affects women.
What is a Transient Ischemic Attack(TIA) An episode of cerebrovascular insufficiency with temporary episodes of neurological dysfunction,Lasting 15 minutes to 24 hours Most resolve within 3 hours Warning sign of an underlying pathological condition
S/S of Transient Ischemic Attack Most common deficit Contralateral weakness of the lower face, hands, arms, and legs Transient dysphasia Some sensory impairment Loss of vision, inability to speak 1/3 of TIA patients will have a stroke within 5 years
Transient Ischemic Attack Medical conditions,Hypertension, Atherosclerosis,Cardiac disease,Diabetes mellitus,Kidney disease,Peripheral vascular disease
causes of Transient Ischemic Attack (same as hypertension) Cigarette smoking,high cholesterol,Stress, Cocaine use,Sedentary lifestyle,Oral contraceptives,Obesity
Transient Ischemic Attack Signs and Symptoms Clinical picture will vary depending on area of brain involved.
Transient Ischemic Attack Subjective data; Time of onset,Presence of headache hemorrhagic stroke -HA is described as sudden & explosive,Sensory Impairment Inability to think clearly Numbness or tingling Visual problems Inability to speak/understand
Transient Ischemic Attack Objective data: Hemiparesis or hemiplegia,Change in LOC Signs of increased ICP,Respiratory problems Presence of aphasia or dysphagia,Impaired coordination,Auscultate the carotid artery for a bruit
Manifestations of strokes Contralateral hemiplegia or paresis Contralateral sensory loss,Spatial-perceptual deficits,Dysphasia or aphasia if dominant hemisphere is involved,Expressive aphasia-inability to speak,Receptive aphasia-inability to understand written/spoken language
Manifestations of strokes Confusion and emotional lability Impaired short term memory Impaired visual field Hemianopia-visual field defect inability to see the right (left sided stroke) or left (right sided stroke) half of an image.
strokes Diagnostic Test CT an MRI will reveal changes in density and differentiate between infarction or hemorrhage,Differentiate from other disorders such as brain tumors or cerebral edema,Shows the size and location of injury Position Emission Tomography (PET)
strokes Diagnostic Test Cerebral angiography shows displacement or blockage of blood vessels Ultrasonography - indicate size of blood vessels and direction of blood flow A lumbar puncture may be performed to check for blood in the CSF (only if ICP normal)
In the case of a TIA a Diagnostic Test cerebral angiogram,Doppler,computer tomographic angiography(CTA),magnetic resonance angiography (MRA)
Strokes Medical Treatment Strokes are a Medical Emergency. Triaged, transported and treated rapidly Treatment varies,Treatment directed by the cause
Strokes Medical Treatment Anticoagulation therapy is used in patients with thrombolytic stroke, contraindicated in hemorrhagic stroke,t-PA for the first 24 hours then Heparin,Coumadin,Lovenox
Strokes Medical Treatment Platelet antiaggregation medication (contraindicated in hemorrhagic stroke) ASA,Dipyridamole (Persantine)Ticlopidine (Ticlid),Clopidrogel (Plavix)
Strokes Medical Treatment Hemorrhagic strokes may require surgical intervention,Evacuate the clot,Aneurysm clipped or tied off
Strokes Medical Treatment Vasodialating agents(Osmotic diuretics)may be prescribed to reduce cerebral edema Dexamethasone (Decadron)to reduce IICP Fluids are usually restricted for the first few days,Suppositories, stool softness, laxatives
Strokes Medical Treatment Carotid endarterectomy: If atherosclerosis of the carotid artery is the cause,Crainiotomy: the treatment for aneurysm,Transluminal angioplasty
Strokes Medical Nursing Management Prevent Neurological deficits. Frequent Neuro assessments (at least once per shift.) Maintain accurate neurological flow sheet Observe the patient closely for signs of progression of the CVA; be particularly aware of change in LOC, motor ability,
Strokes Medical Nursing Management Assess ability to swallow Keeping accurate I&O record Intravenous fluids (until patient stabilizes),nasogastric tube feeding or oral feedings (depending upon patient's abilities) Suction equipment at bedside
Strokes Medical Nursing Management Maintain proper positioning/body alignment/skin integrity Prevent complications of bed rest decubiti, hypostatic pneumonia, contracture Apply footboard, sandbags, trochanter rolls and splints as necessary,Keep head of bed elevated 30 degrees,
Strokes Medical Nursing Management Maintain adequate elimination Foley catheter,bladder retraining (during rehabilitation) Stool softeners prevent constipation or straining which will increase intracranial pressure and encourage another hemorrhage
Strokes Medical Nursing Management Continually orient patient to person, place and time (day, month) even if patient remains in a coma Confusion possible result of just regaining consciousness or from neuro deficit the patient can hear you even if he/she cannot respond to you
Strokes Medical Nursing Management Place all objects requiring the patient's use in an area bound by his/her intact vision or movement limitations. Hemianopia,Unilateral neglect,Protect eye on the affected side if needed Instilling artificial Tears, as ordered
Hemianopia Nursing Management Include patient's family and significant others in plan of care to the extent possible Allow them to assist with care when feasible Keep them informed Help them to understand the patient's condition Home safety concerns rugs and electrical cords
Hemianopia Rehabilitation Multidisciplinary team approach Tasks faced by the patient include Compensation for impaired functions Independence in activities of daily living (ADL) Behavior patterns to prevent the recurrence of symptoms medications Stop smoking
Hemianopia Rehabilitation Individualized exercise program involving both affected and unaffected extremities. Speech therapy, as indicated by patient's condition.Counseling and support to family is an integral part of the rehabilitation process
Hemianopia Rehabilitation Counseling and support (cont) Hemiplegic patients may be easily confused, forgetful, withdrawn and dependent Be supportive and optimistic but firm and direct,Avoid doing things for the patient that they can do for themselves.
Hemianopia Nursing Diagnosis Communication impaired related to ischemic injury,Self care deficit related to loss of function Nutrition imbalance, less than body requirements, related to impaired ability to swallow.
