[Cerebrospinal fluid transfer of cefbuperazone in the blood-brain barrier lesions of neurosurgical patients].

Cefbuperazone (CBPZ) was given in 15 patients after surgery. There was no infections except for 1 case in which signs of infections were suspected. As side effects, slight elevations in hepatic transaminase levels were observed in 3 patients during the CBPZ chemotherapy. CBPZ concentrations in 7 patients were studied. The subjects were divided into 3 groups according to CT finding during the chemotherapy to correlate CBPZ concentrations to degrees of blood-brain barrier lesions; Group I: no enhancement, Group II: mild or focal enhancement, Group III: diffuse and marked enhancement. It was interesting to note that the more marked enhancement were obtained, the higher levels of CSF concentration of CBPZ.
