[Ventricular staphylococcal infections. Treatment with vancomycin by continuous venous infusion].

Thirteen cases of meningeal and/or ventricular infection and 1 case of septicaemia, all caused by staphylococci, were treated with continuous intravenous infusions of vancomycin. Repeated measurements of vancomycin plasma and CSF levels by microbiological assay or by high performance liquid chromatography showed that the antibiotic entered the CSF after 48 hours of treatment and that its concentrations in CSF remained stable at 1 to 4 micrograms/ml (mean: 2 micrograms/ml) throughout the 3 weeks' treatment period. After treatment was discontinued, vancomycin became undetectable in CSF within less than 24 hours.
