Final answer:
Acute bacterial meningitis in adults is treated with intravenous antibiotics, possibly ampicillin and gentamicin, along with other medications to reduce inflammation. Hospitalization is necessary for supportive care, and treatment is guided by the results of a lumbar puncture.
Step-by-step explanation:
The recommended treatment for acute bacterial meningitis in adults typically involves a combination of intravenous antibiotics, which may include ampicillin and gentamicin, or others depending on the specific bacterial pathogen. A lumbar puncture, also known as a spinal tap, is performed to diagnose meningitis by analyzing cerebrospinal fluid (CSF). In some cases, other medications such as corticosteroids may be used to reduce inflammation. Treatment may be initiated empirically while awaiting lab results. Depending on the causative organism, different antibiotics may be prescribed, like doxycycline, fluoroquinolones, cephalosporins, or carbapenems. Hospitalization is usually required for supportive care, observation, and the administration of intravenous medications. A course of oral antibiotics may follow once the patient is stable.
