Continuous intravenous administration of vancomycin in medical intensive care unit patients.

The aim of this study was to evaluate continuous vancomycin infusion (contV) in intensive care unit patients.A retrospective study in 164 patients treated with contV was conducted. They were compared with 75 patients treated with intermittent vancomycin infusion.The median duration of vancomycin therapy in the contV group was 6 (5%-95% percentile range, 2-21) days. The median daily vancomycin dose in the contV group was 960 (526-1723) mg, resulting in a median serum vancomycin plateau concentration of 19.8 (9.8-29.4) mg/L (target: 15-25 mg/L). The contV administration regime was sufficient regarding achievement of the target serum vancomycin concentration. However, in the contV group, serum vancomycin levels were frequently in a subtherapeutic range on treatment days 1 (44%), 2 (29%), and 3 (23%). In the contV group, serum vancomycin concentration determinations per treatment day were performed significantly less often compared with the intermittent vancomycin infusion group (0.38 [0.15-0.75] vs 0.43 [0.22-1.00], P = .041).In medical intensive care unit patients, contV is sufficient to achieve target serum vancomycin concentrations. Because contV frequently resulted in subtherapeutic drug levels on the first days of therapy, a higher loading or starting dose might be necessary.     «
