    Study Notes

    Chapter 64: Management of Patients with Neurologic Infections, Autoimmune Disorders, and Neuropathies

    • This chapter focuses on the management of patients with neurologic infections, autoimmune disorders, and neuropathies.
    • Learning objectives include differentiating infectious nervous system disorders, describing the pathophysiology and management of multiple sclerosis, myasthenia gravis, and Guillain-Barré syndrome, utilizing the nursing process for patient care, explaining cranial nerve disorders and their management, and applying the nursing process to cranial nerve disorders.

    Infectious Neurologic Disorders

    • Meningitis: Inflammation of the meninges (membranes surrounding the brain and spinal cord). Two main types: bacterial and viral. Bacterial meningitis is often caused by Streptococcus pneumoniae or Neisseria meningitidis. Aseptic meningitis is caused by viral infection. Symptoms include headache, fever, changes in LOC, stiff neck, positive Kernig and Brudzinski signs, and photophobia.

    • Brain Abscesses: Collections of infectious material within brain tissue. Most commonly caused by bacteria. Symptoms include headache (often worse in the morning), fever, vomiting, neurological deficits, and signs of increased intracranial pressure (ICP). ICP increases as the abscess expands, leading to decreased LOC and seizures. Diagnosis is done using MRI or CT scans, and CT-guided aspiration is used to identify the causative organisms.

    • Encephalitis: An acute, inflammatory process of the brain tissue. Caused by viral infections (e.g., herpes simplex virus [HSV], West Nile virus, St. Louis encephalitis virus) or fungal infections. Symptoms include headache, fever, confusion, hallucinations, rash, flaccid paralysis, and Parkinson's-like movements.

    • Creutzfeldt-Jakob Disease (CJD) and Variant CJD (vCJD): Rare, degenerative, transmissible spongiform encephalopathies (TSEs). Caused by prions (small proteinaceous particles). Not spread by casual contact. vCJD may be contracted through ingestion of infected beef. Symptoms include cognitive impairments, sensory and motor problems, behavioral changes, and sleep disturbances. There is no effective treatment. The disease is progressive and fatal, typically within one year.

    Meningitis: Medical Management

    • Prevention by meningococcal vaccine.
    • Early administration of high doses of appropriate intravenous (IV) antibiotics for bacterial meningitis.
    • Dexamethasone (review dosing).
    • Close contacts with patients should receive chemoprophylaxis using rifampin, ciprofloxacin, or ceftriaxone.
    • Treatment for dehydration and shock (fluid and volume expanders).
    • Monitoring for signs of increasing intracranial pressure (ICP).
    • Monitoring for decreased level of consciousness (LOC) and focal motor deficits.
    • Monitoring for signs of sepsis.
    • Recognizing signs like an abrupt onset of high fever, shock, disseminated intravascular coagulation (DIC), and purpura.

    Meningitis: Nursing Management

    • Collaborate with the care team for critically ill patients.
    • Frequent neurological assessment, including vital signs and level of consciousness.
    • Pain and fever management.
    • Protect the patient from injury related to seizure activity or altered LOC.
    • Monitor daily weight, electrolytes, urine volume, specific gravity, and osmolality.
    • Prevent complications associated with immobility.
    • Review laboratory tests.
    • Providing supportive care in a quiet, controlled, darkened room.
    • Facilitate coping for the patient and family.

    Brain Abscess: Medical and Nursing Management

    • Medical management is focused on controlling increased ICP and draining the abscess.
    • Appropriate antibiotic therapy, initiated as soon as possible based on culture and sensitivity, is crucial.
    • Corticosteroids may be used to treat cerebral edema, and anticonvulsants might be necessary to control seizures.
    • Nursing management includes frequent and ongoing neurological assessments, administering medications, assessing the patient's response to treatment, and providing supportive care.

    Encephalitis: Medical Management

    • Acyclovir for HSV infection.
    • Antifungal agents for fungal infection (up to 3 weeks).
    • Frequent and ongoing neurological assessments.
    • Dim lighting, limited visitors, and clustering of care.
    • Analgesics and cautious opioid use.
    • Monitoring of kidney function with antiviral use.
    • Supportive care.

    Creutzfeldt-Jakob Disease: Medical Management

    • Prevention of disease transmission via blood and body fluid precautions.
    • Use of disposable medical instruments whenever possible.
    • Supportive and palliative care.
    • Psychological support.

    Autoimmune Nervous System Disorders

    • This section covers multiple sclerosis (MS), myasthenia gravis, and Guillain-Barré syndrome.

    Multiple Sclerosis (MS):

    • An immune-mediated, progressive demyelinating disease in the central nervous system.
    • Clinical manifestations vary.
    • Four main clinical forms.
    • Higher prevalence in northern, colder latitudes.
    • Onset usually between 20 and 50 years of age. Affects women more than men.
    • Commonly relapsing and remitting, with exacerbations and recurrences of symptoms, including fatigue, weakness, numbness, balance problems, pain, and visual disturbances.

    Myasthenia Gravis:

    • An autoimmune disorder affecting the myoneural junction.
    • Characterized by varying degrees of weakness of voluntary muscles.
    • Antibodies impair acetylcholine transmission at the myoneural junctions.
    • Two clinical forms: ocular and generalized. Initial symptoms often involve the ocular muscles (diplopia, ptosis).
    • Generalized weakness can affect facial muscles, swallowing, voice, and all extremities, potentially progressing to intercostal muscles and respiratory failure (myasthenic crisis).
    • Diagnostic tests include acetylcholinesterase inhibitor testing (with atropine on hand to prevent side effects), and ice tests for those with cardiac or asthma issues.

    Guillain-Barré Syndrome:

    • An autoimmune disorder causing an acute attack on peripheral nerve myelin.
    • Rapid demyelination can lead to respiratory failure and autonomic dysfunction (e.g., CV instability).
    • Often triggered by a viral infection (1-3 weeks prior).
    • Maximum weakness peaks within 2-4 weeks.
    • Variable manifestations include weakness or paralysis that starts in the lower extremities and ascends symmetrically, bulbar weakness, cranial nerve symptoms, tachycardia, bradycardia, hypertension, or hypotension.
    • Includes supportive treatment (plasma exchange, immunoglobulin or IVIG). Recovery rates vary, but most patients improve fully.

    Cranial Nerve Disorders

    • This section discusses specific cranial nerve disorders like trigeminal neuralgia (tic douloureux), Bell's palsy

    Trigeminal Neuralgia:

    • Condition of the fifth cranial nerve, characterized by brief, sudden attacks of severe pain.
    • Pain may be unilateral and is described as shooting, stabbing, or burning.
    • Most commonly affects the second and third branches of the trigeminal nerve.
    • Vascular compression is often a cause.
    • Common in the fifth and sixth decades of life, and may occur in people with multiple sclerosis.
    • Patients may avoid stimulation (e.g., eating, washing face).

    Bell's Palsy:

    • Unilateral inflammation of the seventh cranial nerve causing facial paralysis.
    • Symptoms include unilateral facial muscle weakness or paralysis, facial distortion, increased lacrimation, and possibly pain in the facial area.
    • Most patients recover completely in 3 to 5 weeks.
    • Treatment focuses on maintaining muscle tone and preventing denervation.

    Medical and Nursing Interventions

    • Summaries of medical and nursing interventions for each disorder are presented throughout the notes. These interventions are specific for each condition and may include medications, supportive care, prevention of complications, managing symptoms, patient education, and emotional support. There is a particular focus on recognizing and addressing signs of impending complications (e.g., increased ICP in meningitis) from the outset.
