Background

  • Meningismus is difficult to discern if <6mo, (esp if <2mo)
  • <3months old
    • 1% incidence of bacterial meningitis
    • E. coli, Group B strep, listeria
  • >3months old
    • S. pneumo, meningococcus, staph

Diagnosis

Bacterial Meningitis Score for >2mo and well-appearing

  • Risk Factor
    • Peripheral blood ANC >10K
    • Seizure
    • CSF
      • CSF ANC >1000
      • CSF protein >80
      • CSF Gram stain (if + 61% Sn, 99% Sp)
  • Any risk factor = high risk for bacterial meningitis
  • Very low risk if infant lacks all risk factors

Work-Up

  1. CBC
  2. CSF

DDx

Treatment

  • Neonates - IV ampicillin + gentamicin, with dosages and frequencies according to BW and age
    • If suspecting S. pneumoniae, add vancomycin
    • Empiric therapy for late-onset includes anti-staph agent plus ceftazidime, amikacin, or meropenam
    • Ceftriaxone may cause bilirubin encephalopathy in neonates
  • Infants and children - Vancomycin 60 mg/kg/d q6h plus Ceftriaxone 100 mg/kg/d q12h
  • Length of Tx depends on organisms isolated

Disposition

  • Admit despite negative meningitis score if:
    • Age <2mo w/ any degree of pleocytosis
    • Appear ill
    • Infants w/ aseptic meningitis
  • If likely viral meningitis still give ceftriaxone x 1, f/u in 24hr
