Cerebral edema refers to swelling in the brain caused by trapped fluid. Common causes include a traumatic brain injury, stroke, tumor. By definition cerebral edema is the excess accumulation of water in the intra-and/or extracellular spaces of the brain [1]. Pathophysiology. Pathophysiology of cerebral edema at cellular level is complex. Damaged cells swell, injured blood vessels leak and blocked absorption pathways force fluid to enter brain tissues. The treatment of cerebral edema is dependent on the cause. Essential nonpharmalogical intervention includes maintaining an open airway and avoiding.

[Cerebral edema and its treatment].

Medication Depending on the severity of your condition and the underlying cause, doctors may prescribe you medication to help reduce swelling and prevent blood clots. Osmotherapy When your brain cerebral edema, it accumulates excess fluid.


Osmotherapy cerebral edema a technique meant to draw water out of the brain. This is done using osmotic agents such as mannitol, or high-salt saline.

Osmotic therapy also helps improve blood circulation. How can Cerebral Edema be prevented? CE can be prevented by early recognition and management of disease processes that are associated with the development of CE and increased ICP.

Additionally, public cerebral edema measures to minimize traumatic brain injury and popularize the recognition of common conditions associated with CE and increased ICP are highly important. For example, contact sports with high risk for pediatric head injury are being extensively reviewed cerebral edema modified to make conditions of play safer with minimal risk for head injuries.

Cerebral Edema

What is the evidence? Most of the evidence cerebral edema rationale for treatment options is derived from expert consensus as randomized controlled trials are lacking. Guidelines for management of cerebral edema and raised ICP have been developed by the Brain Cerebral edema Foundation and are freely available at www.

In Principles of Critical Care, 3rd edition". Ongoing controversies regarding etiology, diagnosis, treatment Controversies regarding etiology and pathophysiology of CE sub-types: Controversies regarding diagnosis of CE: This creates an abnormal pressure gradient and movement of water cerebral edema the brain, which can cause progressive cerebral edema, resulting in a spectrum of signs and symptoms from headache and ataxia to seizures and coma.

Interstitial[ edit ] Interstitial edema occurs in obstructive hydrocephalus due to a rupture of the CSF—brain barrier. This results in trans-ependymal flow of CSF, causing CSF to penetrate the brain and cerebral edema to the extracellular spaces and the white matter. Cerebral edema cerebral edema differs from vasogenic edema as CSF contains almost no protein.

Treatments[ edit ] Treatment approaches can include osmotherapy using mannitoldiuretics to decrease fluid volume, corticosteroids to suppress the immune system, hypertonic saline, and surgical decompression to allow the brain tissue room to swell without compressive injury.

For example, Gao and Ang used the finite element method to study changes in intracranial pressure during craniotomy operations.

Glutamate and N-methyl-D-aspartate receptor antagonists improve cerebral microcirculation cerebral edema metabolism. Trometamol corrects cerebral acidosis.

Extended cerebral edema is treated surgically via a bilateral decompressive craniotomy, sometimes including craniotomy of lateral and posterior fossae.
