Cerebrospinal fluid antibiotic concentrations in ventricular shunt infections.
The concentration of antibiotic in cerebrospinal fluid was measured during treatment of seven children with infected ventricular shunts. Antibiotics were administered via the ventricular shunt or through an external ventricular drain. 53 CSF samples were obtained 7-19 h after antibiotic administration. Wide variation in cerebrospinal fluid antibiotic concentration occurred from patient to patient following either route of administration. For optimal management of shunt infections, we recommend periodic assessment of antibiotic concentration or activity in ventricular fluid and determination of the minimum inhibitory concentration of antibiotic required for each pathogen.
