Central nervous system infections
Central nervous system (CNS) infections are severe and potentially life-threatening conditions that require urgent recognition and management. These infections, including meningitis, encephalitis, brain abscesses, and ventriculitis, can lead to neurological deterioration, raised intracranial pressure, and systemic complications if not treated promptly.
The management of CNS infections in critically ill patients involves rapid diagnosis, targeted antimicrobial therapy, and supportive care. Lumbar puncture and neuroimaging are key to confirming the diagnosis, while empiric antibiotic or antiviral therapy should be initiated without delay. Corticosteroids, seizure management, and intracranial pressure control are often required in severe cases. For brain abscesses or ventriculitis, surgical intervention may be necessary to drain infected material and relieve pressure.
Preventing CNS infections is equally crucial, particularly in high-risk populations such as immunocompromised patients, neurosurgical cases, or those with invasive devices like external ventricular drains. Vaccination programs, infection control measures, and early prophylactic interventions can help reduce incidence. A multidisciplinary approach involving neurologists, infectious disease specialists, and intensivists is essential to optimizing outcomes in critically ill patients with CNS infections.
