Nursing Management of the Adult Patient with Neurological Alterations Prepared by: Hikmet Qubeilat. RN,MSC. Brain Needs… Blood flow Glucose Oxygen Diagnostic Studies Skull and Spinal Radiology CT (Computerized Tomography) MRI (Magnetic Resonance Imaging) PET (Positron Emission Tomography) EEG (Electroencephalogram) EMG (Electromyelogram) Cerebral Blood Flow Studies Neurological Assessment Level of Consciousness (LOC) Pupils Vital Signs (VS) Neuromuscular status Response to stimuli Posturing Glasgow Coma Scale (GCS) I. Neurological Disorders The normal functioning of the CNS can be affected by a number of disorders, the most common of which are headaches, tumors, vascular problems, infections, epilepsy, head trauma, demyelinating diseases, and metabolic & nutritional diseases. Headaches Not always chronic…be careful Classified based on characteristics of the headache Functional vs. Organic type May have more than one type of headache History & neurologic exam diagnostic keys Pattern Tension Migraine Cluster Site Bilateral, basilar, bandlike Unilateral, anterior Unilateral, occular Quality Squeezing, constant Throbbing Severe Pattern Cycles, years Periodic, years Remitting, relapsing Duration Days, weeks, months Hours, days 30-90 min Onset Anytime Prodrome, starts in AM Nocturnal Assoc. S&S Stiff neck N&V, photo/phonophobia ONSET: Not reliable or diagnostic Horner syndrome HA: Essential History Onset this particular headache Character of pain, severity and duration Associated symptoms Prior history, pattern Original onset: prior testing, treatment Other therapeutic regimens Physical Exam Neurologic examination Inspect for local infections, nuchal rigidity Palpation for tenderness, bony swellings Auscultation for bruits over major arteries Organic vs. Traumatic vs. Functional: Diagnostics CBC: underlying illness, anemia Chem panel: if associated vomiting, dehydrated CT scan: for focal neurological signs, sinus No LP for suspected ICP; ↑ association with brain herniation Don’t Miss It 1. Caused by subarachnoid hemorrhage from an aneurysm or head injury 2.“Worse headache of my life” 3. Changes in LOC, focal neurological signs 4. Highly correlated with CVA 5. Untreated, 50 % mortality Headache Teaching Guide Keep a calendar/diary Avoid triggers Medications (purpose, side effects) Stress reduction Dark quiet room, exercise, relaxation Regular exercise Intracranial Pressure (ICP) Brain Components Skull is a rigid vault that does not expand It contains 3 volume components: Brain tissue: (80%) or 2% of TBW Intravascualr blood: (10%) CSF: (10%) Intracranial Pressure (ICP) Intracranial Pressure (ICP) is the pressure exerted by brain tissue, blood volume & cerebral spinal fluid (CSF) within the skull. ICV = Vbrain + Vblood + Vcsf Normal ICP – 10 to 15 mmHg Cerebral Perfusion Pressure (CPP) CPP = MAP – ICP Normal CPP – 70 to 100 mmHg Normal CSF – 5 to 13 mmHg Increased Intracranial Pressure (IICP) fluid pressure > 15 mm Hg IICP is a life threatening situation that results from an in any or all 3 components within the skull > volume of brain tissue, blood, and / or CSF Cerebral edema: > H2O content of tissue as a result of trauma, hemorrhage, tumor, abscess, or ischemia Acute Coma Levels of consciousness diminish in stages: • Confusion: can’t think rapidly and clearlyالتشويش • Disorientation: begin to loose consciousness • Time, place, self • Lethargy: spontaneous speech and movement limited • Obtundation: arousal (awakeness) is reduced • Stupor: deep sleep or unresponsiveness • Open eyes to vigorous or repeated stimuli • Coma: respond to noxious stimuli only • Light (purposeful), full coma (non-purposeful), deep coma (no response) Multiple Sclerosis is a chronic autoimmune disorder affecting movement, sensation, and bodily functions. It is caused by destruction of the myelin sheath covering nerve fibres in the central nervous system (brain and spinal cord). Causes: 1. Autoimmune destruction. 2. Heredity. 3. Viruses. 4. Environmental factors. 19 Diagnostic Test: 1. MRI. 2. Physical examination. 20 Clinical Manifestations: * Early: 1. Muscle weakness causing difficulty walking 2. loss of coordination or balance 3. numbness or other abnormal sensations 4. visual disturbances, including blurred or double vision 21 * Late: 1. Fatigue . 2. Muscle spasticity and stiffness 3. Tremors. 4. Paralysis . 5. pain . 6. Vertigo. 7. Speech or swallowing difficulty . 8. Loss of bowel and bladder control. 9. Sexual dysfunction . 10. Changes in cognitive ability 22 Treatment: 1. Immunosuppressant drugs . These drugs include corticosteroids such as prednisone and methylprednisolone, the hormone adrenocorticotropic hormone (ACTH), and azathioprine. 2. Physiotherapy. 3. Occupational therapy. 23 Parkinson's Disease is a progressive movement disorder marked by tremors, rigidity, slow movements (bradykinesia), and postural instability. It occurs when, for unknown reasons, cells in one of the movement-control centers of the brain begin to die. Causes: 1. Degeneration of brain cells in the area known as the substantia nigra, one of the movement control centers of the brain. 2. Drugs given for psychosis, such as haloperidol (Haldol) or chlorpromazine (Thorazine), may cause parkinsonism. 24 Clinical Manifestations 1. Tremors 2. Slow movements (bradykinesia), freezing in place during movements (akinesia). 3. Muscle rigidity or stiffness, occurring with jerky movements 4. Postural instability or balance difficulty occurs. 5. Masked face. 6. Depression 7. Speech changes 8. Problems with sleep 9. Emotional changes10. Incontinence. 11. Constipation. 12. Handwriting changes, 13. (dementia) 25 Treatment: 1. Maintain regular exercise (physical therapy, occupational therapy) 2. Provide good nutrition to maintain health. 3. Drugs that replace dopamine (levodopa) 4. If the patient is unresponsive or intolerant to pharmacotherapy, Electro convulsive therapy is indicated. Nursing Management * Observe the patient's mood, cognition; organization and general well being * Observe for features of depression, *Suicidal precautions to be followed, if the patient exhibits any suicidal ideas *Instruct the patients to speak slowly and clearly, and to pause and take a deep breath at appropriate levels. 26 Parkinson's Disease (cont’d) *In dementia, environmental modification is followed *Avoid frequent change in the environment to minimise confusion if the memory deficit is very severe, name boards and signboards by the side of the rooms and things will be very helpful. *Sedatives are used if sleep related problems are noticed, when sleep hygiene is unsuccessfully. * Patients should not be forced into situations in which they feel ashamed of their appearance. *Encourage the patient to participate in moderate exercises, free-moving sports like swimming. *Advise the patient to organize thoughts before speaking and encourage the client to use facial expression and gestures if possible to assist with communication. 27 Seizure Disorders & Epilepsy Seizure: paroxysmal, uncontrolled electrical discharge of neurons in the brain that interrupts normal function Epilepsy: spontaneously recurring seizures caused by a chronic underlying condition Two major classes: Generalized Partial Depending on type, phases may include: Prodromal phase- signs & activity preceeding seizure Aural phase- sensory warning Ictal phase- full seizure Postictal phase- recovery Aura Phase I’m seeing spots I feel very angry! I taste metal! I smell bananas! I’m dizzy !
