Pharmacokinetics of vancomycin and meropenem during continuous online hemodiafiltration: A case report

The pharmacokinetics of vancomycin and meropenem in patients treated with continuous online hemodiafiltration (OL-HDF) are not well understood.We evaluated dialytic clearance and serum concentrations of vancomycin and meropenem by OL-HDF in a critically ill patient with soft tissue infection. The mean clearance of OL-HDF and mean serum concentrations during continuous OL-HDF were 155.2 mL/min and 23.1 µg/mL for vancomycin and 145.6 mL/min and 22.7 µg/mL for meropenem.Vancomycin and meropenem showed high clearance rates during continuous OL-HDF. However, continuous infusion of these agents at high doses maintained therapeutic serum concentrations.
