Improved vancomycin dosing in children using area under the curve exposure.
: Our objectives were to (1) determine the pharmacokinetic indices of vancomycin in pediatric patients; and (2) compare attainment of 2 target exposures: area under curve (AUC) / minimum inhibitory concentration (MIC) ≥400 and trough concentration ≥15 mcg/mL. ⋯ : Targeted exposure using vancomycin AUC/MIC, compared with trough concentrations, is a more realistic target in children. Depending on age, serum creatinine and MIC distribution, vancomycin in a dosage of 60 to 70 mg/kg/day was necessary to achieve AUC/MIC ≥ 400 in 75% of patients.

Local vancomycin treatment has been shown to decrease sternal wound complication rates. Whether a similar effect can be achieved at other surgical sites is unknown. This study investigates the effect of local vancomycin on inguinal wound complication rates after vascular procedures. ⋯ Addition of intraoperative local vancomycin did not improve the rates of inguinal wound dehiscence or deep infections but had a positive impact on superficial wound infections.

Vancomycin is administered as antimicrobial prophylaxis to patients undergoing cardiac surgery, an intervention that usually requires cardiopulmonary bypass (CPB). Previous studies reported that CPB modifies vancomycin pharmacokinetic parameters. ⋯ In our study there were no significant differences in vancomycin Cmax, AUC0-8, Vd, and Cl between the on-pump and off-pump groups. CPB does not seem to significantly modify intraoperative vancomycin pharmacokinetics in patients undergoing cardiac surgery. The results of this study may contribute to increased knowledge of vancomycin pharmacokinetics.

Continuous infusion of vancomycin in septic patients receiving continuous renal replacement therapy.
Vancomycin is frequently administered as a continuous infusion to treat severe infections caused by Gram-positive bacteria. Previous studies have suggested a loading dose of 15 mg/kg followed by continuous infusion of 30 mg/kg in patients with normal renal function; however, there are no dosing recommendations in patients with renal failure undergoing continuous renal replacement therapy (CRRT). Data from all adult septic patients admitted to a Department of Intensive Care over a 3-year period in whom vancomycin was given as a continuous infusion were reviewed. ⋯ On Day 1, 43 patients (51%) had adequate drug concentrations (20-30 μg/mL), 17 (20%) had levels >30 μg/mL and 25 (29%) had levels <20 μg/mL. Most patients with adequate drug concentrations received a daily dose of 16-35 mg/kg. The intensity of CRRT directly influenced vancomycin concentrations on Day 1 of therapy.

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. ⋯ 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.
