Purulent meningitis management

1. Initial Measures

  • Ensure ABCs (Airway, Breathing, Circulation)
  • Start empirical IV antibiotics immediately after blood cultures:
    • Ceftriaxone or cefotaxime + vancomycin
    • Add ampicillin if *Listeria* is suspected (elderly, neonates, immunocompromised)
  • Administer dexamethasone (10 mg IV q6h) ideally before or with first antibiotic dose

2. Diagnostic Workup

  • Blood cultures x2
  • Lumbar puncture (LP), unless contraindicated:
    • CSF: cell count, glucose, protein, Gram stain, culture, PCR
  • CT/MRI before LP if:
    • Altered mental status
    • Focal neurologic signs
    • Signs of raised intracranial pressure

3. Supportive Care

  • ICU monitoring for severe cases
  • IV fluids and antipyretics
  • Anticonvulsants if seizures
  • ICP management (mannitol, hypertonic saline, EVD)

4. Targeted Antibiotic Therapy

  • Adjust based on culture and sensitivity
  • Duration:
    • *N. meningitidis*: 5–7 days
    • *H. influenzae*: 7–10 days
    • *S. pneumoniae*: 10–14 days
    • *Listeria*, *Gram-negatives*: ≥21 days

5. Management of Complications

  • Hydrocephalus → consider EVD or ventriculoperitoneal shunt
  • Sensorineural hearing loss → audiology referral
  • Neurological deficits → rehabilitation, follow-up
