Meningitis bacterial risk factors?
Meningitis Viral risk factors?
Meningitis Viral Priority Interventions?
Meningitis Bacterial Priority Interventions?
Risk factors for bacterial meningitis:
Age: bacterial meningitis is common among those under age 20.
Immunosuppression
Comorbid conditions such as diabetes mellitus, hypo parathyroidism, chronic kidney failure
Splenectomy and sickle cell disease which increases the risk of meningitis secondary to encapsulated organisms.
Alcoholism and cirrhosis
Recent exposure to others with meningitis with or without prophylaxis.
Contiguous infection such as sinusitis
Dural defect ( eg. Surgical, traumatic)
HIV infection which predisposes to bacterial meningitis caused by encapsulated organisms primarily Streptococcus pneumoniae, and opportunistic pathogens.
Thalassemia major
Intravenous drug abuse
Ventriculopertoneal shunt
Risk factors for viral meningitis:
Compromised immune system: AIDS, diabetes, use of immunosuppressant drugs.
Age: viral meningitis occur in children less than 5 years.
Skipping vaccines: lncreases the risk for anyone who hasn't completed the recommanded vaccination schedule.
Contact with rodent droppings or urine( lymphocytic choriomeningitis virus)
Travel history
Intravenous drug abuse
Some cranial congenital deformities
Faecal contamination
Bite from an infected insects like mosquito etc
Viral meningitis interventions:
Monitor signs and neurological status of the patient.
Observe for any signs of increased intracranial pressure such as headache, vomiting, drowsiness, decresed alterness and bulging fontanelle in infants.
Monitor arterial blood gases and oxygen saturation to determine the presence of hypoxia.
Adminster oxygen as necessary
Ensure proper hydration.
Adminster medications when necessary
● Osmotic diuretics such as mannitol which is used to treat cerebral edema by promoting cerebral blood flow.
● Anticonvulsents such as diazepam or phenytoin
●Antivirals such as acyclovir
Bacterial meningitis intervention:
Nursing interventions | Rationales |
Monitor vital signs and neurological status | Increasing systolic BP accompanied by decreasing diastolic BP is an ominous sign of increased ICP |
Observe for any signs of increased intracranial pressure | Signs and symptoms that indicate an increase in ICP includes headache, vomiting, drowsiness, bulging fontanelle(infants) |
Assess for nuchal rigidity, twitching, increased restlessness, irritability | These are signs of meningeal irritation, which may happen because of infection |
Observe for increased restlessness, moaning, guarding behaviors | These nonverbal cues may indicate increasing ICP or pain. Unrelieved pain can potentiate increased ICP. |
Monitor arterial blood gases and oxygen saturation | Determines presence of hypoxia and indicate therapy needs. |
Maintain head or neck in midline position, provide small pillow for support | Turning head to one side compresses the jugular veins and inhibits venous drainage thereby increasing ICP |
During reposition, avoid bending of the knee and pushing heels against the mattress | These activities increaseintra thoracic and intraabdominal pressure thereby increasing ICP |
Provide comfort measures and decrease external stimuli such as quiet environment, soft voice and gentle touch | produces relaxing effect which decreases adverse physiologic response and promotes rest to maintain or lower ICP |
Elevate the head of the bed 30degree and avoid neck flexion and hip flexion | promotes venous drainage from head, thereby reducing cerebral vasodilation and elevate ICP |
Adminster oxygen as necessary | Used to treat cerebral edema by promoting cerebral blood flow |
Adminster medications as indicated:
Osmotic diuretics such as mannitol which can be used to treat cerebral edema by promoting cerebral blood flow
Anticonvulsents such as diazepam or phenytoin which can be used to control seizures related to increased intracranial pressure.
Antibacterials such as pencillins, vancomycin, cephalosporins
