The Monitoring of Brain Edema and Intracranial Hypertension

Abstract

Preventing secondary brain injury after neurological insults is one of the primary goals of the neurocritical care unit. Our understanding of the roles of intracranial pressure (ICP) and cerebral edema in managing patients in the neurocritical care units is still evolving. Recent clinical trials examining the monitoring and treatment of elevated ICP have influenced the way we think about intracranial hypertension. Additionally, new methods of monitoring ICP, new physiologic surrogates derived from ICP measurements, and evolving technology to measure cerebral edema are currently being studied and tested for clinical efficacy. In this article, we will discuss both traditional and novel methods of monitoring ICP and cerebral edema.
