  • MENINGITIS Case Presentation Aquino, Sheila Mae B. Austria, Tiffany M. Cabigao, Marc Andrew
  • Meningitis
    • Condition where the brain and the spinal cord meninges become inflamed
    • Usually as a result of bacterial, viral, fungal infection.
    • Can be further classified as aseptic, septic, or tuberculous.
  • The CNS consists of the brain, the spinal cord and the surrounding membranes or meninges that protect the delicate tissues from normal trauma. These tissues are also protected by the skull, the vertebral column, and the cerebrospinal fluid (CSF), the fluid in the subarachnoid space which serves as a cushion.
  • The dendrites transmits impulses to the cell nucleus; the axon transmits impulses away from the cell nucleus to body organs. These cells vary in size ranging from a few inches to several feet long, reaching from distant body sites such as feet, through the spinal cord, and to the brain.
    • The brain is covered by three membranes: the dura matter ( a fibrous, connective tissue structures containing many blood vessels), the arachnoid membrane (a delcicate serous membrane), and the pia matter ( a vascular membrane).
  •  
  • Etiology
    • Bacterial meningitis is caused by bacteria and is rare, but is usually serious and can be life-threatening if it's not treated right away.
    • Common agents are:
        •  Group B streptococcus
        •  Escherichia coli
        •  Listeria monocytogenes
        •  S treptococcus pneumoniae (pneumococcus)
        •  Neisseria meningitidis (meningococcus)
        •  Haemophilus influenza type b (Hib)
        • Aseptic/Viral meningitis is caused by viruses.
    • Common agents are:
            •  Coxsackievirus
            •  Poliovirus
            •  Hepatitis A
            •  Herpesvirus
  • Epidemiology
    • Bacterial meningitis occurs in about 3 people per 100,000 annually in western world.
    • Population-wide studies have shown that viral meningitis is more common, at 10.9 per 100,000, and occurs more often in the summer.
    • In Sub-saharan Africa, large epidemics of meningococcal meningitis occur in the dry season, leading to it being labeled the "meningitis belt"; annual rates of 500 cases per 100,000 are encountered in this area, which is poorly served by Health Care.
    • Meningococcal disease occurs in epidemics in areas where many people live together for the first time, such as army barracks during mobilization, college campuses.
  • Transmission Meningitis is spread by direct contact with a carrier’s secretions, especially by respiratory droplets. People may be carrier’s only, without having he actual disease.
  • High-risk groups
        • 1. Anyone who lives in close contact with many people.
        • 2. Anyone who has frequent upper respiratory infections.
        • 3. Anyone who has had trauma or an invasive procedure involving the brain, spinal cord, or sinuses.
  • Signs and Symptoms 1. Signs of infection
    • Fever
    • Chills
    • Malaise
    2. Signs of increased intracranial pressure
    • Headache
    • Vomiting
  • 3. Signs of meningeal irritation
    • Nuchal rigidity (stiff neck)
    • Opisthotonos (backward arching of the body in muscle spasms)
    • Photophobia (sensitivity to light)
    • Diplopia (double vision)
    • Delirium, stupor, coma: indicates a decreasing level of consciousness, an agitated state followed by a progressive decrease in consciousness, and ultimately a lack of any response.
  • (+) Brudzinski's sign (+) Kernig's sign
  • 4. Children may exhibit any of the signs and symptoms listed above, as well as these signs:
    • Bulging fontanelle
    • Twitching, seizures, and coma
  • Treatment
        • Bed rest
        • I.V. fluid administration
        • Oxygen therapy
        • Medications
        • Anticonvulsant (prevent seizures ): Phenytoin (Dilantin),
        • Phenobarbital (Barbita, Luminal, Solfoton)
        • Analgesic or antipyretic (to treat fever and muscle aches ): acetaminophen (Tylenol or Panadol), nonsteroidal anti-inflammatory drugs(NSAIDs) Aspirin
        • ibuprofen, ketoprofen, and naproxen
        • ( reduce pressure within the brain): Dexamethasone (corticosteroid medicine), Mannitol (Osmitrol)
    • Antibiotics - depend on the isolated microorganism
  • Prevention
        • Haemophilus vaccine (HiB vaccine)
        • (MMR) vaccine (measles, mumps, and rubella )
        • meningococcal vaccine (MCV4)
        • pneumococcal conjugate vaccine
        • Good personal hygiene
        • Avoiding people who have meningitis.
  • Lab and Diagnostic Exams Meningitis is diagnosed by analysis of the spinal fluid. Spinal fluid is obtained by a procedure called the lumbar puncture or spinal tap in which a needle is introduced into the space between vertebraeL-3 and L-4, because the spinal cord ends at L-2. Spinal fluis is withdrawn from the subarachnoid space.
    • A CBC will indicate acute infection. Bacterial antigen testing may also be done.
    • A Gram’s stain will determine the presence of bacteria. A full culture should be done with sensitivity.
    • Radiograph y skull and spine x-rays used to identify sinus infections, fracture, or osteomyellitis; chest x-rays may be used to identify respiratory infections, abscesses, lesions, or granulomas.
    • CT scan will usually be normal in uncomplicated cases of meningitis, but can show diffuse enhancement in some types or show hydrocephalus.
    • Electroencephalogram may be performed to show slow wave activity.
  • Pathophysiology Enters the bloodstream & Crosses the blood-brain barrier BACTERIA Invasion of the nasopharynx Proliferates the CSF Inflammation of the subarachnoid & pia mater Increased ICP
  • Theoretical Framework Wellness or Disease Pure or Fresh Water Pure Water Light Efficient Drainage Cleanliness
            • Nightingale’s Environmental Theory
    • Florence Nightingale defined nursing as “the act of utilizing the environment of the patient to assist him in his recovery”. Based on her theory the five environmental factors: pure or fresh air, pure water, efficient drainage, cleanliness and light affect client’s illness or health. Any deficiencies in these five factors produced lack of health or illness.

  • Nursing Diagnosis
        •  Hyperthermia related to positive bacterial infection as manifested by flushed and warm to touch skin.
        •  Acute pain related to meningeal irritation with spasm of extensor muscles (neck, shoulders and back) as manifested by positive kernig’s and brudzinski’s sign.
        •  Risk for ineffective cerebral tissue perfusion related to increased intracranial pressure.
        •  Risk for infection related to presence of infective organisms
        •  Risk for injury related to presence of infection
        •  Altered thermoregulation related to compression of hypothalamus
        •  Altered family processes related to having a child with a serious illness
  • Nursing Management
        •  Monitor vital signs constantly. Determine oxygenation from arterial blood gas values and pulse oximetry.
        •  Give oxygen to maintain arterial partial pressure of oxygen.
        •  Reduce high fever to decrease load on heart and brain from oxygen demands.
        •  Rapid intravenous fluid replacement may be prescribed, but take care not to overhydrate patient because of risk of cerebral edema.
        •  Assess clinical status continuously; evaluate skin and oral hygiene; promote comfort; and protect patient during seizures.
        •  Implement infection control precautions and respiratory isolation until 24 hours after start of antibiotic therapy
        •  Inform family about patient’s condition
  • Nursing Care Plan CUES NURSING DIAGNOSIS GOAL NURSING INTERVENTION EVALUATION SUBJECTIVE: “ Mataas pa din ang lagnat nya hanggang ngayon” as verbalized by the patient’s mother. OBJECTIVE: -flushed skin -skin warm to touch -38.2 ºC -PR 109 -RR 34 -BP 90/60 Hyperthermia related to positive bacterial infection as manifested by flushed and warm to touch skin Short term: Within 1 hour of nursing intervention, the patient’s elevated temperature of 38.2 o C will lessen to 37.4 o C. Long term: Within 3 consecutive days of nursing intervention, the patient’s body temperature will return to its normal range. Establish rapport to mother to gain trust and cooperation Promote surface cooling by means of undressing ( heat loss by radiation and conduction) Demonstrate on ways on how to do proper Tepid Sponge Bath using wet and dry cloth Provide nutritious diet to meet increased metabolic demands Administer antipyretics as ordered . After 1 hour of nursing intervention, the goal is partially achieved as manifested by temperature of 37.7 o C.
  • CUES NURSING DIAGNOSIS GOAL NURSING INTERVENTION EVALUATION Subjective: “ Umiiyak yan kapag nagagalaw yung batok niya tska nung may ginawa si doctor sa kanya” Objective: - facial grimace - irritable - ( + ) Brudzinski’s sign - ( + ) Kernig’s sign Acute pain related to meningeal irritation with spasm of extensor muscles (neck, shoulders and back) as manifested by positive kernig’s and brudzinski’s sign. Within 2 hours of nursing intervention, the patient’s pain from 8 will reduce to 4 using the facial pain rating scale. Use pain rating scale appropriate to it’s age. Assess for neurologic status and vital signs. Position on the side with head gently supported in extension. Promote rest by keeping stimulation in the room to a minimum. Institute respiratory isolation. Monitor and record carefully intake and output. Administer mediation as ordered. After 2 hours of nursing intervention, there is no sign of facial grimace and irritability from the patient.
  • CUES NURSING DIAGNOSIS GOAL NURSING INTERVENTION EVALUATION Objective: - lethargic - change in motor responses - changes in papillary reaction Risk for ineffective cerebral tissue perfusion related to increased intracranial pressure Within an hour of nursing intervention, the nurse will be able to educate the patient’s mother about the causes and symptoms of ineffective cerebral tissue perfusion Educate patient’s mother about the causes of ineffective cerebral tissue perfusion. Observe carefully for signs of increased intracranial pressure such as; lethargy, shrill cry, hyperactive reflexes, decreased pulse and respiratory rate, increased blood pressure and temperature Carefully monitor the rate of all IV infusions to prevent overhydration Check for the urine’s specific gravity to detect oversecretion or undersecretion of ADH due to pituitary pressure Measure head circumference and weight Monitor vital signs After an hour of nursing intervention, the patient’s mother is educated about the causes and symptoms of ineffective cerebral tissue perfusion.
    • Discharge Planning
    • Medicines:
    • -take your (antibiotics) medications as prescribed by physician.
    • -do not quit taking your (antibiotics) meds until your physician say so
    • Wellness:
    • -eat a variety of healthy foods such as fruits and vegetables
    • -drink more liquid like water, juices and milk
    • -avoid stress by providing calm and clean environment, stress causes slow healing.
    • Health teaching:
    • -teach patient’s mother how to perform oral care and it’s benefits
    • Check-up:
    • -teach patient’s mother to have a regular check-up in the health center or in the nearest hospital.
