    Journal: Jpn J Antibiot; 1988 Apr; 41(4):409-14. PubMed ID: 3404651.
    Abstract:
    Cefoperazone (CPZ) was administered to 10 patients with cerebrovascular disturbances at acute and chronic phases to investigate its passage into the cerebrospinal fluid. The antibiotic was administered at dosages of 1 g and 2 g to patients in the acute phase to examine the dose-dependency. The results obtained are summarized as follows: 1. Serum concentrations Peak values of CPZ were 46.9 +/- 4.42 microgram/ml in acute phase patients in 1 g dosage group (acute group 1), 253.1 +/- 63.2 micrograms/ml in acute phase patients in 2 g dosage group (acute group 2), and 197.9 +/- 15.7 micrograms/ml in chronic phase patients in 2 g dosage group (chronic group 2) at 1 hour after CPZ administration. Concentrations of CPZ varied about 5-fold between the 1 g dosage group and the 2 g dosage groups. The acute group 2 showed generally higher values of CPZ concentrations than the chronic group 2. 2. Cerebrospinal fluid concentrations. Peak values were 0.96 +/- 0.30 microgram/ml (at 3 hours) in acute group 1, 4.55 +/- 3.41 micrograms/ml (at 1 hour, except 1 case) in acute group 2, and 1.29 +/- 1.28 micrograms/ml (at 1 hour) in chronic group 2. Acute group 2 showed generally higher values than chronic group 2. 3. CPZ was considered useful for the prevention of postoperative infections in the field of brain surgery.
