Treatment of Bacterial Meningitis in Basilar Skull Fracture or Cochlear Implant
Clinical Scenario
This protocol applies to patients presenting with bacterial meningitis who have a basilar skull fracture or a cochlear implant — anatomical factors that affect pathogen risk and inform the selection of treatment.
Treatment Approach
Management involves intravenous antibiotic combination therapy alongside adjunctive corticosteroid therapy, with eligibility criteria based on patient age.
Clinical Goal
The primary target is clinical improvement after 48 hours of appropriate treatment.

- Vancomycin plus ceftriaxone
- Alternative: meropenem plus vancomycin
- Because the etiology is not known at presentation, dexamethasone should be given before or at the time of initial antibiotics while awaiting the final culture results in all patients older than six weeks with suspected bacterial meningitis.
- Dexamethasone can be discontinued after four days or earlier if the pathogen is not H. influenzae or S. pneumoniae, or if CSF findings are more consistent with aseptic meningitis.
- Repeat LP is generally not needed but should be considered to evaluate CSF parameters in persons who are not clinically improving after 48 hours of appropriate treatment.
