Cephalosporins, like other antimicrobials, are not known to be metabolized in the CSF; thus, their concentrations in CSF depend on the balance between penetration and elimination. In another study, the activity of human CSF containing cefotaxime obtained from children with meningitis who received high dose cefotaxime was tested in vitro against cephalosporin-resistant S. Above all a disciplined approach consisting of a thorough physical examination and evaluation of clinical response to treatment are important in tailoring appropriate dose and duration of antibiotics in neonates with suspected or proven sepsis. These results are, however, in contrast to data presented by Cottagnoud et al. Creatinine negatively influences the Cl of cefepime.

A large observational study of pneumococcal meningitis cases from Brazil showed that penicillin resistance was associated with higher mortality even after adjustment for age and severity of illness. In most clinical trials, the penetration of cephalosporins through the blood—brain barrier is expressed as the ratio of CSF to blood concentration at a particular time-point Table Steroids have anti-inflammatory effects and decrease the release of various cytokines. Continuous infusion of vancomycin makes it possible to achieve a constant bactericidal level in blood and may also result in better CSF penetration 4. Ciprofloxacin mg in a single dose is also effective. Once an organism has been identified and the antimicrobial susceptibility pattern is known, antibiotic therapy can be simplified or modified Table Bactericidal rates were

For the exact determination of the CL in , repeated measurements of CSF drug concentrations early after an intravenous drug injection are necessary
