Patient's question:
Sick for many years, due to a blow to the head and hard work, bad mood, and overexertion.Doctor's answer:
Disease Analysis: Cerebral edema (brain edema) is formed in the brain tissue due to excessive accumulation of fluid, which is a significant cause of increased intracranial pressure.Guidance: It should include the following four aspects:
① All systemic factors that may potentially exacerbate brain edema should be corrected first. Maintain airway patency; keep the unconscious patient warm; perform tracheostomy if necessary; correct shock; and improve blood oxygen partial pressure.
② Reduce intracranial pressure and relieve brain herniation.
③ Eliminate cerebral edema. The primary approach relies on reducing intracranial pressure and diuretics.
④ Remove the underlying cause. The physician should provide corresponding treatment for conditions such as tumors, inflammation, or trauma. Due to the different etiologies of brain edema, the causes vary, and the treatment should be tailored accordingly. The following plans can be referred to:
① Vasogenic brain edema can be treated with corticosteroids (e.g., dexamethasone, which can protect the blood-brain barrier, reduce capillary permeability, stimulate cerebral blood flow and metabolism, and inhibit cerebrospinal fluid production); drugs that inhibit cerebrospinal fluid production; hypothermia; and short-term use of hyperosmotic dehydration drugs (e.g., mannitol, sorbitol).
② Cytotoxic brain edema can be improved by correcting respiratory issues, resolving metabolic disorders, removing the cause, using hyperosmotic dehydration drugs and diuretics (powerful loop diuretics such as furosemide, etc.), and using drugs that promote cellular metabolism; hyperbaric oxygen therapy.
③ Interstitial brain edema can be treated with drugs that inhibit cerebrospinal fluid secretion, diuretics, and cerebrospinal fluid shunting.
④ For osmotic brain edema, fluid intake should be limited; hypotonic sodium syndrome should be corrected; and hypertonic saline solution should be administered. For brain edema caused by non-ketotic hyperosmolar hyperglycemia, insulin should be used first to lower blood sugar, followed by Na+ supplementation to restore balance.
