Complications and sequelae of brain chemosynthesis

If the brain is infected by bacteria or viruses, inflammation will occur, and symptoms such as nausea, vomiting, fever, and even confusion will appear. If not treated in time, it may leave sequelae. We all know that the heart, brain and kidneys are important organs of the human body, especially the brain. A person's study, work, thoughts and consciousness are all controlled by it. Next, let’s talk about the complications and sequelae of cerebral infarction.

1. If the fluid in the subdural space exceeds 2 ml, the protein quantity is above 0.4 g/l, and the red blood cell count is below 1 million × 106/l, it can be diagnosed as subdural effusion.

2. Acute diffuse cerebral edema leading to increased intracranial pressure is a common complication. If the condition is severe and progresses rapidly, temporal lobe uncus herniation or foramen magnum herniation may occur. Insufficient understanding and failure to adopt dehydration treatment and timely rescue in time may endanger life. Children with intracranial hypertension need special attention when transferring to other hospitals. Osmotic diuretics should be used to reduce pressure first, and the children can be transferred only after their condition stabilizes. Because the anterior fontanelle and sutures of infants have not yet closed, they can wait for compensation, so the symptoms of increased intracranial pressure are often atypical, and the incidence of brain herniation is relatively rare compared to older children.

3 When suffering from meningitis, purulent exudate can easily block narrow channels or cause adhesions, causing cerebrospinal circulation disorders and producing hydrocephalus. It is common in patients who are treated improperly or too late, especially in newborns and infants. Adhesive arachnoiditis often occurs in the foramen magnum, which can obstruct the circulation of cerebrospinal fluid; or adhesions formed by ventricular meningitis are common causes of obstructive hydrocephalus.

4. In addition to water and electrolyte disorders caused by vomiting, irregular eating and drinking, children with encephalopathy may also suffer from cerebral hyponatremia, with symptoms such as insomnia, convulsions, coma, edema, general weakness, low muscle tone in the limbs, and oliguria. Its occurrence mechanism is related to the infection affecting the posterior pituitary gland, causing excessive secretion of antidiuretic hormone and leading to water retention.

5 Brain parenchymal damage and adhesions can cause cranial nerve involvement or limb paralysis, and may also cause brain abscess, intracranial arteritis and secondary epilepsy. Fulminant meningococcal disease may be accompanied by DIC and shock. In addition, otitis media, pneumonia, and arthritis may occasionally occur.

The above introduces the complications and sequelae of purulent meningitis, which allows us to better understand purulent meningitis. Purulent meningitis is very harmful, so we must pay attention to it.
