Intracranial infection is a frequent complication in cranial surgery, because during or after surgery, the closed cranial environment is somewhat open, and some bacteria and pathogens may have the opportunity to infect the central nervous system, resulting in a variety of physical symptoms in patients. The main clinical symptoms of intracranial infection are headache, nausea and vomiting, and high fever, which can cause more serious damage to the brain tissue if left untreated and can lead to seizures and possibly death. If you’re not treated, the damage to your brain tissue can be more serious, causing seizures and possibly death. Can blood tests for intracranial infection reveal it? In the examination of intracranial infection, the blood routine alone can not directly confirm the diagnosis, and intracranial infection can be divided into bacterial and viral types, bacterial infection blood routine will indicate elevated white blood cells, but viral infection white blood cells may be normal. Therefore, in order to better confirm the diagnosis of intracranial infection, it is necessary to do further tests, effective means of examination are laboratory tests, cranial X-ray examination and cranial CT examination, etc., and most importantly, cerebrospinal fluid culture. Cranial infections are more serious than general body infections, and if the presence of intracranial infection is confirmed by the above diagnostic methods, it should be actively treated. At present, there are two kinds of treatment for intracranial infection, namely medication and surgery. For patients with milder conditions, they may be able to get some improvement through medication, but if the condition is serious, surgery should be arranged in time.
