Pharmacokinetic parameters and dosage of aminoglycosides (AGs) were studied retrospectively in 36 patients with neutropenic fever after stem cell transplantation in Seoul National University Hospital from July 1996 to June 2001. AGs pharmacokinetic parameters were calculated with steady-state peak and trough serum drug concentrations by the method of Sawchuk and Zaske et at. The calculated aminoglycosides volume of distribution and clearance were greater than population value . The average dosage of aminoglycosides required to maintain optimal serum AGs concentration was also greater than recommended dose in insert paper. The average dosage of amikacin was mg/kg every 12 hours (In case of tobramycin, mg/kg every 8 hours or mg/kg every 12 hours). The relationship between AGs volume of distribution and sex, serum albumin (g/dl), body mass index , body weight change , the amount of fluid inpu (ml/kg/day), the degree of hematocrit decrease were studied respectively. Univariate anlysis revealed that body mass index , the amount of fluid input (ml/kg/day) and the degree of hematocrit decrease had significant correlation with aminoglycosides volume of distribution. But sex, serum albumin, body weight change had no significant correlation with aminoglycosides volume of distribution.
