Septic meningitis brain nodes are characterized by significantly high general pressure, cloudy or purulent appearance, white blood cell count in the hundreds to thousands, predominantly multinucleated cells, significantly increased protein, significantly decreased sugar and chloride, and pathogenic bacteria detectable by cerebrospinal fluid culture. Septic meningitis is a very serious infection and once diagnosed, it requires prompt, regular treatment. Antibiotics that can easily cross the blood-brain barrier, such as ceftazidime, ceftriaxone, cefotaxime, etc., can be used appropriately until the pathogenic bacteria are clearly identified. For septic meningitis where the pathogenic bacteria have been identified, targeted anti-infective drugs should be selected for regular treatment based on drug sensitivity testing, which is more beneficial to the prognosis of the disease.
