  • Title: [A study on penetration of antibiotics into the cerebrospinal fluid after the ventriculo-peritoneal shunt (author's transl)].
    Author: Imagawa K, Kawasaki M, Toda I, Hayashi M, Asai A, Nomura T.
    Journal: Jpn J Antibiot; 1982 Apr; 35(4):1072-9. PubMed ID: 7097985.
    Abstract:
    Neurological surgeon must select the effective antibiotics to bacterium, that which penetrated enough to the intracranial organ through the blood-brain barrier. In this study, we measured the concentration of cefotiam (CTM), cephalothin (CET), cephacetrile (CEC) and sulbenicillin (SBPC) into the cerebrospinal fluid in the non inflammatory cases with V-P shunt. 1. Antibiotic concentrations in CSF and CSF/serum ratio (%) were evaluated at 2 hours after an intravenous administration of antibiotics. CTM; 0.543 microgram/ml (3.66%), CET; 1.84 micrograms/ml (7.45%), CEC; 1.77 micrograms/ml (7.5%), SBPC, 6.15 micrograms/ml (5.58%). 2. The peak of antibiotic concentration in CSF appeared from 2 hours after administration and gradually decreased. In cellular tumor cases, the penetration of antibiotics into CSF showed similar levels as the cerebrovascular disease cases. 3. Concentration of CTM in CSF was higher than MIC of CTM to S. pyogenes and E. coli.
