MENINGITIS
Meningitis is an inflammation of the lining around the brain and
spinal cord caused by bacteria or viruses.
- Bacterial meningitis is caused by bacteria.
- Meningitis can be the primary reason a patient is hospitalized
or can develop during hospitalization.
- Meningeal infections generally originate in one of two ways:
through the bloodstream or by direct spread.
- N. meningitidis concentrates in the nasopharynx and is
transmitted by secretion or aerosol contamination.
- One of the causative organism enters the bloodstream, it
crosses the blood brain barrier and proliferates in the
cerebrospinal fluid.
- The host immune system stimulates the release of cell wall
fragments and lipopolysaccharides, facilitating inflammation of the
subarachnoid and pia mater.
CAUSES OF B.MENINGITIS
NURSING ASSESSMENTS
Assessment of the patient with bacterial meningitis include.
- Neurologic status. Neurologic status and vital signs are
continually assessed.
- Pulse oximetry and arterial blood gas values. These values are
used to quickly identify the need for respiratory support.
NURSING DIAGNOSIS
Based on the assessment data, major nursing diagnoses
include:
- Risk for Infection related to contagious nature of
organism.
- Acute Pain related to headache, fever, neck pain secondary to
meningeal irritation.
- Impaired Physical Mobility related to intravenous infusion,
nuchal rigidity and restraining devices.
- Activity Intolerance related to fatigue and malaise secondary
to infection.
- Risk for Impaired Skin Integrity related to immobility,
dehydration, and diaphoresis.
- Risk for Injury related to restlessness and disorientation
secondary to meningeal irritation.
- Interrupted Family Process related to critical nature of
situation and uncertain prognosis.
- Anxiety related to treatment and risk of death.
- Risk for Ineffective Therapeutic Regimen Management
NURSING CARE PLANNING AND GOALS
Goals for a patient with bacterial meningitis include:
- Protection against injury.
- Prevention of infection.
- Restoring normal cognitive functions.
- Prevention of complications
NURSING INTERVENTIONSI
Important components of nursing care include the following
measures:
- Assess neurologic status and vital signs constantly. Determine
oxygenation from arterial blood gas values and pulse oximetry.
- Insert cuffed endotracheal tube (or tracheostomy), and position
patient on mechanical ventilation as prescribed.
- Assess blood pressure. (usually monitored using an
arterial line) for incipient shock, which precedes cardiac or
respiratory failure.
- Rapid IV fluid replacement may be prescribed, but take care not
to overhydrate patient because of risk of cerebral edema.
- Reduce high fever to decrease load on heart and brain from
oxygen demands.
- Protect the patient from injury secondary to seizure activity
or altered level of consciousness (LOC).
- Monitor daily body weight; serum electrolytes; and urine
volume, specific gravity, and osmolality, especially if syndrome of
inappropriate antidiuretic hormone (SIADH) is suspected.
- Prevent complications associated with immobility, such as
pressure and pneumonia.
- Institute infection control precautions until 24 hours after
initiation of antibiotic therapy (oral and nasal discharge is
considered infectious).
- Inform family about patient’s condition and permit family to
see patient at appropriate intervals.
DISCHARGE AND HOME CARE GUIDELINES
After hospitalization, the patient at home should:
- Activities. Alternate rest and activity to conserve
energy.
- Diet. Consume safe, clean, and healthy foods.
- Asepsis. Promote simple infection control procedures at
home.
- Infectious process. Identify signs and symptoms of an
infectious process and report to the physician promptly.
