Cerebral edema and intracranial hypertension syndrome in children

Intracranial hypertension refers to a series of clinical manifestations caused by an increase in brain volume and weight caused by an increase in brain parenchymal fluid. In pathology, the accumulation of free fluid in the interstitial space of brain cells is called cerebral edema, while the increase in fluid in brain cells is called brain swelling, but it is difficult to distinguish between the two in actual clinical work or the difference in the same pathological process. This stage is often coexisting in the later stages, so it is often collectively referred to as cerebral edema. Obvious and persistent cerebral edema causes intracranial hypertension, which is more common in certain pediatric diseases, especially acute infectious diseases. Early diagnosis and timely treatment of intracranial hypertension is one of the important measures to control cerebral edema, prevent the formation of cerebral hernia, and reduce mortality and disability.
