  • Title: Vancomycin elimination during high-flux hemodialysis: kinetic model and comparison of four membranes.
    Author: DeSoi CA, Sahm DF, Umans JG.
    Journal: Am J Kidney Dis; 1992 Oct; 20(4):354-60. PubMed ID: 1415203.
    Abstract:
    Vancomycin clearance was measured in five patients during dialysis with cuprophane (CU), polysulfone (PS), cellulose triacetate (CT), and polyacrylonitrile (PAN) dialyzers. Vancomycin was significantly cleared during routine high-flux (HF) hemodialysis (HD) with the latter three membranes, but not by CU. Postdialytic rebound of serum vancomycin concentrations was noted following HF dialysis, necessitating use of a two-compartment pharmacokinetic model. Measurement of serum vancomycin concentration immediately postdialysis significantly overestimates intradialytic removal, possibly resulting in inappropriate dose adjustment. Vancomycin infusion during HF HD results in significant drug removal during its administration to the patient, complicating the calculation of an adequate dose.
