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
- CBC
- CSF
DDx
Treatment
- Neonates - IV ampicillin + gentamicin
- 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
