Possibilities of perfecting antimicrobial therapy. Dynamics of penicillin G concentrations in the cerebro-spinal fluid in purulent meningitis.
In 43 adult patients with purulent meningitis receiving daily doses of 1-4,000,000 IU penicillin G i.v. in bolus, determinations were made, 1-6 hrs after administration, in 153 samples of cerebrospinal fluid (CSF), to ascertain the concentrations of penicillin that have reached the CSF. After 1 hour maximum levels of penicillin were noted, exceeding by far the meningococcus and pneumococcus minimum inhibitory concentration (MIC). Generally, high penicillin concentrations persisted in the CSF, in most of the cases at least for the following 6 hours. The advantages of using penicillin G i.v. in doses of 1-3,000,000 IU in bolus at 12 hour intervals are discussed. All the 36 patients with meningococcal meningitis and 3 of the 5 with pneumococcal meningitis recovered with this therapeutic scheme, under daily control of the CSF.
