Intracranial infections are a common neurosurgical condition with a high incidence and can occur at any age. What causes intracranial infections and are they serious? It has been found that there are many clinical factors that cause intracranial infections, including encephalitis, meningitis, brain abscess and various post-operative intracranial surgical infections. The common pathogens of encephalitis include infectious virus, bacteria, rickettsiae, parasites, etc., while the common pathogens of meningitis include diplococcus, pneumococcus and H. influenzae, etc. Brain abscess is usually caused by the spread of bacteria in the brain through blood circulation or neighboring infected foci, in addition, intracranial infection is also easily triggered after hydrocephalus shunt. The danger of intracranial infection Intracranial infection is a very serious clinical complication, which should be paid enough attention and controlled in time. The mortality rate is very high if it is not handled properly. Initially, the patient may have fever, headache, vomiting, and as the condition further deteriorates, followed by convulsions, aphasia, hemiplegia, mental disorder, and impaired consciousness, etc. If effective countermeasures are not taken at this time, the condition will only get worse and the patient may be bedridden for a long time or even die. Treatment of intracranial infections Intracranial infections can be treated in local hospitals in general, but due to the existence of the blood-brain barrier, the effect of drug treatment is poor, and patients may form drug-resistant bacterial infections due to improper treatment or delayed treatment, thus making the condition more severe. Therefore, in the treatment process of intracranial infection patients, choosing a regular hospital, a senior expert and a scientific and effective technology can not only achieve the ideal treatment effect, but also effectively avoid many problems. Now there is a set of advanced characteristic treatment technology, which has unique advantages and advanced experience in the treatment of intracranial infections, and can achieve good results for various intracranial infections with high patient satisfaction.
