Causes and treatment of purulent meningitis

The occurrence of purulent meningitis may be related to bloodstream infection, direct invasion of adjacent lesions, iatrogenic infection, treatment methods include antibacterial treatment, reduction of intracranial pressure, surgical treatment, etc. 1. Bloodstream infection This is the most common infection route of purulent meningitis, bacteria invade meninges through blood stream, causing inflammation. This condition is usually secondary to bacteremia or other parts of the body Suppurative lesions (such as skin, respiratory tract, digestive tract, etc.). 2. Inflammation of adjacent tissues directly invading adjacent lesions, such as otitis media, sinusitis, skull osteomyelitis, etc., may spread directly to the meninges, resulting in purulent meningitis. In addition, open brain trauma, skull fracture, or congenital sinuses such as neural canal insufficiency may also allow bacteria to enter the meninges directly. 3. iatrogenic infection in cerebrospinal fluid drainage, brain surgery and other medical processes, if improper operation or disinfection is not strict, may also cause intracranial infection, but this situation is relatively rare.2. treatment 1. antibacterial treatment early use of adequate, full course of antibiotics is the key to treatment. Before the pathogen is not clear, broad-spectrum antibiotics are usually used, such as ceftriaxone, cefotaxime, cefixime, etc. once the pathogen is clear, sensitive antibiotics should be selected for treatment.2. Reduce intracranial pressureFor patients with elevated intracranial pressure, mannitol, furosemide and other drugs can be used to reduce intracranial pressure. 3. Surgical treatment For patients with hydrocephalus, surgical treatment may be required, such as median foramen adhesion release, aqueduct dilation and hydrocephalus shunt.
