Neurologic Disorders Flashcards
Bacteria reaches the meninges via the bloodstream from a nearby infection (or if an open wound like a neuro procedure)
CSF: sugar and water
Risk: septic, facial surgeries, ear infections, immunizations, trauma to brain
Infections grow easily in CSP
Increased ICP s/s
What will our CSF look like?
Most commonly caused by:
See in kids
Kernig
Brudzinski
Diagnosis: blood cultures if infect, CBC, cultures, LP - often done
Nursing interventions
Medications
Complications:
Prevention!
Bacterial meningitis
Increase in WBC and protein
Decrease in sugar
We now also have WBC in the CSF
Cloudy
WBCs = lot
Happens quickly - growing crazy - hard get in there but once there crazy - do lumbar puncture - fund bacteria in there and fluid cloudy and decreased amounts sugar because bacteria ate it - increased WBC
Lyse bacteria - WBC - creating protein - increased protein
No longer neutral now in acidic
Meninges flared and unhappy - lot neurologic effects
What will our CSF look like? - Bacterial meningitis
Neisseria meningitidis (Meningococcal) - past newborn phase often these
Streptococcus pneumoniae (pneumococcal) - past newborn phase often these
Haemophilus influenzae (Hib) - past newborn phase often these
Escherichia coli - no vaccine; common in neonates
Most commonly caused by: - Bacterial meningitis
Fever, cold hands and feet
Fretful, dislike being handled
Rapid breathing or grunting
Unusual cry, moaning
Stiff neck, dislike bright lights
Refusing food and vomiting
Drowsy, floppy, unresponsive
Pale, blotchy skin, spots/rash
Tense, bulging fontanelle
Photosensitivity, neck stiffness, look sick
High pitched cry
Seizures/convulsions
First 18 months: - See in kids - Bacterial meningitis
Fever, cold hands and feet
Drowsy, diff to wake
Severe muscle pain
Severe headache
Dislike bright lights
Vomiting
Confusion and irritability
Pale, blotchy skin, spots/rash
Stiff neck
Photosensitivity, neck stiffness, look sick
Seizures/convulsions
Older: - See in kids - Bacterial meningitis
Straighten knee
Painful - so ball up
Inflamed meninges
Kernig - Bacterial meningitis
Pull knees up when head is pulled up
Brudzinski - Bacterial meningitis
Droplet precautions
Monitor
Head circumference - lot inflammation in brain; monitor fontanels
Environment
Comfort measures
Safety
Down foramen magnum - brain herniation - cannot help
Seizures - seizure precautions - decrease stimuli - bring temp down - tepid bath - no ice directly on them - fan in there
Nursing interventions - Bacterial meningitis
Steroid- reduce body’s response to infection - reducing inflammation - not want herniation
Antibiotic- treat infection
Analgesics- pain meds - in pain
Give fluid
Edema or fluid overload going on in brain - with brain trauma - no mannitol - brain starving - infection eaten all sugar - little left for brain to consume - even more fluid away from brain - much as possible so as much sugar left for brain
Medications - Bacterial meningitis
Hearing loss
Neurologic deficit
Seizures
Visual impairment
Behavioral problems
CP = e coli in first couple weeks life = not good
Complications: - Bacterial meningitis
Seizure precautions - pad sides, suction, oxygen, loose clothing, educate parents
During a seizure - time it unless lasting longer than 5 min - meds like phenobarbitol; turn on side
Post seizure - turn on side; recovery position; slowly reorient; let rest
Keep lights down and talk quietly
Seizures
What is the best way to prevent bacterial meningitis?
Vaccines
Prevention! - Bacterial meningitis
Acute encephalopathy and fatty liver disease
Typ always seen after viral infection (often flu) and given aspirin
Present sim to meningitis - do LP to ensure
Do support measures - not many interventions can do - monitor I&O, hydration, no flexion - no bending head or overbending of body
Reye syndrome primarily affects the liver and brain, causing liver dysfunction and cerebral edema.
The cause of Reye syndrome is not understood.
The prognosis for the client who has Reye syndrome is best with early recognition and treatment which includes ruling out other illnesses that have manifestations similar to Reye syndrome.
Manifestations include:
A lumbar puncture should be done to rule out meningitis due to similarity in manifestations.
Reye syndrome
Association between using aspirin (salicylate) for treating fevers caused by viral infections
Reye syndrome typically follows a viral illness (influenza, gastroenteritis, varicella)
The cause of Reye syndrome is not understood. - Reye syndrome
Lethargy
Irritability
Combativeness
Confusion
Delirium
Profuse vomiting
Seizures
Loss of consciousness
Manifestations include: - Reye syndrome
