Increased intracranial pressure in acute bacterial meningitis

Abstract

Acute bacterial meningitis (ABM) is associated with increased intracranial pressure (ICP) caused by bacterial invasion and the host response to infection. Antibiotic therapy is a sine qua non, and adjunct dexamethasone decreases mortality. The ICP increase may have a rapid course and death due to herniation is most often seen within the first week. Evidence regarding treatment of increased ICP in ABM is limited; this review summarises observational studies which point towards reduced mortality by applying a structured approach towards normalization of ICP in ABM.
