Key Points about Bacterial Meningitis:
- Definition: Bacterial meningitis is an acute infection of the meninges, the protective membranes covering the brain and spinal cord, caused by bacteria such as Neisseria meningitidis or Streptococcus pneumoniae.
- Causes: It is commonly caused by bacterial pathogens, with risk factors including immunocompromised states, certain infections, and head trauma.
- Symptoms: Symptoms include severe headache, neck stiffness, fever, photophobia, and altered mental status. In infants, irritability and poor feeding may be seen.
- Diagnosis: Diagnosis involves clinical assessment and confirmation through lumbar puncture, which reveals cloudy cerebrospinal fluid with elevated white cell count, high protein, and low glucose.
- Management: Immediate treatment with intravenous antibiotics (such as ceftriaxone or penicillin) and supportive care are critical. Corticosteroids may be used to reduce inflammation.
- Complications: Potential complications include neurological deficits, hearing loss, seizures, and in severe cases, death. Early intervention is key to preventing these outcomes.
