What happened to the postoperative brain water

summary

Just after the operation, I feel that my recovery is quite good. However, because the operation site is the brain, I still need to observe more. As a result, there are some symptoms, among which brain edema is more serious. Now let me talk about the brain edema after the operation.

What happened to the postoperative brain water

First, brain edema refers to the increase of water content in the brain, which leads to the increase of brain volume. It is the response of brain tissue to various pathogenic factors. It can cause intracranial hypertension and damage brain tissue. Clinically, it is common in nervous system diseases, such as craniocerebral trauma, intracranial infection (encephalitis, meningitis, etc.), cerebrovascular diseases, intracranial space occupying diseases (such as tumors), seizures and systemic diseases, such as toxic dysentery and severe pneumonia.

Second, the main cause of angiogenic brain edema is the damage and destruction of blood-brain barrier, which leads to the increase of capillary permeability, water leakage and accumulation around blood vessels and intercellular matrix. At this time, some protein substances permeate into the extracellular fluid through the vascular wall with water, which increases the osmotic pressure of the extracellular fluid, and increases the water leakage from the vascular wall, resulting in the continuous development of brain edema. The early stage of traumatic brain edema caused by brain trauma is mainly angiogenic brain edema.

Third: cellular brain edema cellular brain edema is a different pathogenic factor, which changes the internal and external environment of cells, hypoxia of brain tissue, affects the metabolism of nerve cells, dysfunction of cell membrane system, reduction of mitochondrial adenosine triphosphate production, reduction of sodium potassium pump, calcium magnesium pump and other activities of nerve cell membrane, brain edema, and disturbance of sodium, potassium and calcium plasma exchange inside and outside nerve cells. These factors can lead to intracellular edema.

matters needing attention

For patients, some complications of brain surgery are relatively common, and some complications are more serious, so patients have to be hospitalized for more observation, do not want to finish the operation, quickly leave the place full of disinfectant, this is not conducive to timely control of postoperative recurrence.
