Low cefepime concentrations during high blood and dialysate flow continuous venovenous hemodialysis

摘要

Dosing of cefepime during high blood flow (Qb; 300 ml/min), high dialysate flow (Qd; 3 liter/h) continuous venovenous hemodialysis (CVVHD) is undefined. Six patients on CVVHD had serum and effluent cefepime concentrations measured at 0.5, 1, 2, 6, and 12 h after dosing. Three patients had cefepime concentrations less than the MIC for Pseudomonas aeruginosa. A dose of 2,000 mg every 12 h or 1,000 mg every 8 h may increase time at a therapeutic concentration.
