The treatment of cerebral edema depends on the cause and includes monitoring of the person's airway and intracranial pressure, proper positioning, controlled hyperventilation, medications, fluid management, steroids. [3] [7] [8] Extensive cerebral edema can also be treated surgically with a decompressive craniectomy. [7]
Cerebral Edema that resulted from brain tumor is represented by darker areas on this CT image. An increase in cerebral water content is called cerebral edema and it usually results from traumatic brain injury (TBI), subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), subdural hematoma, ischemic stroke, brain tumors, infectious disorders and intracranial surgery.
Hyperventilation is still used if ICP is resistant to other methods of control, or there are signs of brain herniation, because the damage herniation can cause is so severe that it may be worthwhile to constrict blood vessels even if doing so reduces blood flow. ICP can also be lowered by raising the head of the bed, improving venous drainage.
The monitoring of intracranial pressure (ICP) is used in the treatment of a number of neurological conditions ranging from severe traumatic brain injury to stroke and brain bleeds. [1] This process is called intracranial pressure monitoring. Monitoring is important as persistent increases in ICP is associated with worse prognosis in brain ...
First, when the CSF drains too rapidly, a condition known as extra-axial fluid collection can occur. In this condition the brain collapses on itself resulting in the collection of CSF or blood around the brain. This can cause severe brain damage by compressing the brain, and a subdural hematoma may develop. Extra-axial fluid collection can be ...
The infrequency of ICP can be attributed to the invasive nature of the standard monitoring methods (which require insertion of an ICP sensor into the brain ventricle or parenchymal tissue). Additional risks presented to patients can include high costs associated with an ICP sensor's implantation procedure, and the limited access to trained ...
The elevated ICP may cause compression of the brain, leading to brain damage and other complications. A complication often overlooked is the possibility of hearing loss due to ICP. The mechanism of ICP on hearing loss is presumed that the transmission of CSF pressure to and from the Perilymphatic space through a patent cochlear aqueduct.
Progressive cerebral edema may also occur. [27] [30] The increase of blood and brain volume within the skull causes a rapid and severe increase in intracranial pressure, which can in turn cause uncal and cerebellar brain herniation, a disastrous and potentially fatal condition in which the brain is squeezed past structures within the skull.
