Many patients ask if intracranial infections after surgery can be cured. Intracranial infection is a serious disease, mainly meningitis, encephalitis, brain abscess, etc. Intracranial infections in the field of neurosurgery are mostly caused by surgery and post-surgery, and may be life-threatening if not treated early. Nowadays, medical science is so advanced that most patients with intracranial infections can be cured through scientific and reasonable targeted treatment. Intracranial infections are one of the more serious diseases of the central nervous system. If not treated in time, patients may experience a dramatic increase in intracranial pressure, leading to confusion, seizures and respiratory and cardiac arrest, and even life-threatening in severe cases. Some patients go to the hospital in time, but the effect is not very good because of the unreasonable approach, and over time more serious consequences will occur. Currently, the main clinical treatment for intracranial infection is surgery, supplemented by drug therapy. Drugs are generally used for mild cases, but for drug-resistant bacterial infections such as Klebsiella pneumoniae infection and Acinetobacter baumannii infection, conventional anti-infection treatment has little effect and surgery is required. Since the patient’s condition is already very serious at this time, it is particularly important to choose which type of surgery to perform. It is understood that the cerebrospinal fluid specialist technique is summarized after years of clinical practice and research, and it can achieve systematic treatment of various intracranial infections with excellent results. There are many clinical causes of intracranial infections, different sites of infection, and different bacteria of infection, which can lead to different symptoms. Generally speaking, the clinical diagnostic criteria are generally inseparable from these points: 1, clinical symptoms and signs of intracranial infection such as high fever, headache, neck ankylosis, etc.; 2, cerebrospinal fluid examination of white blood cells WBC>0.01X109/L, with an increase in polymorphonuclear cells. Sugar <2.25mmol/L, chloride <120mmol/L, protein >0.45g/L; 3, positive results of cerebrospinal fluid bacterial culture; 4, there is a definite cause of infection, such as cerebrospinal fluid leakage. Anyone who has the 3rd article can confirm the diagnosis, such as a negative cerebrospinal fluid bacterial culture needs to be combined with the rest of the articles.
