OBJECTIVES To evaluate the pharmacokinetics of piperacillin/tazobactam in critically ill patients undergoing continuous renal replacement therapy (CRRT) and to assess the success of the therapy against susceptible bacteria. PATIENTS AND METHODS Sixteen patients undergoing CRRT with different degrees of renal function were included in the study. Blood and(More)
BACKGROUND AND OBJECTIVE Meropenem is a carbapenem antibacterial frequently prescribed for the treatment of severe infections in critically ill patients, including those receiving continuous renal replacement therapy (CRRT). The objective of this study was to develop a population pharmacokinetic model of meropenem in critically ill patients undergoing CRRT.(More)
The pharmacokinetics of piperacillin/tazobactam (4 g/0.5 g every 6 or 8 hours, by 20-minute intravenous infusion) were studied in 14 patients with acute renal failure who underwent continuous venovenous hemofiltration with AN69 membranes. Patients were grouped according to severity (CL(CR) < or =10 mL/min, 10 < CL(CR) < or =50 mL/min, and CL(CR) > 50(More)
The pharmacokinetics of meropenem were characterized in 20 patients with different degrees of renal function who underwent continuous renal replacement therapy. Previously, no differences were detected in vitro in the removal of meropenem by continuous venovenous hemofiltration or continuous venovenous hemodialysis or when AN69 or polysulfone membranes were(More)
BACKGROUND High levels of endotoxin have been reported as a risk factor for mortality in critical patients. Toraymyxin® is a column designed to remove circulating blood endotoxin by direct hemoperfusion widely used in Japan. OBJECTIVES To evaluate the effect of direct hemoperfusion with Toraymyxin® (DHP-PMX) as an adjuvant treatment in patients with(More)
Patients and methods: A prospective, open-label study was conducted in 20 patients undergoing CRRT. Blood and dialysate-ultrafiltrate samples were obtained after administration of 500 mg, 1000 mg or 2000 mg of meropenem every 6 or 8 hours by intravenous infusion. The data were analysed under the population approach using NONMEM version V software. Age,(More)
