The pharmacokinetic parameters of amikacin were determined in a population of 20 adults and 36 pediatric patients admitted into an intensive care unit. Amikacin was administered by repeated intravenous infusion over 0.5 h (600 to 1,350 mg for adults; 70 to 1,500 mg for children). The number of administrations ranged from 2 to 17, and the number of samples(More)
The supposed state of retinal venous occlusions by a thrombus has led to the use of diverse antithrombotic treatments (heparin, fibrinolytic agents). This theory being considered at the moment as controversial, haemorheological theories being more particularly favoured, other treatments are proposed in an attempt to better retinal microcirculation, and this(More)
The objective of this study was to describe amikacin pharmacokinetics (PK) in critically ill patients receiving equal doses (30 ml/kg of body weight/h) of continuous venovenous hemofiltration (CVVH) and continuous venovenous hemodiafiltration (CVVHDF). Patients receiving amikacin and undergoing CVVH or CVVHDF were eligible. Population pharmacokinetic(More)
OBJECTIVE To identify the risk factors of failure and immediate complication of subclavian vein catheterization (SVC). DESIGN Prospective observational study. SETTING Surgical critical care unit of a tertiary university hospital. PATIENTS Critically ill patients requiring a first SVC. INTERVENTION Subclavian vein catheterization was attempted in 707(More)
The pharmacokinetic parameters of amikacin and ceftazidime were assessed in four patients undergoing hemofiltration for septic shock. The parameters were assessed during hemofiltration and in the interim period. The concentration-time profiles of these two drugs in plasma, urine, and ultrafiltrate were investigated after intravenous perfusion (30 min). In(More)
OBJECTIVES Few data are available to guide linezolid dosing during renal replacement therapy. The objective of this study was to compare the population pharmacokinetics of linezolid during continuous venovenous haemofiltration (CVVHF, 30 mL/kg/h) and continuous venovenous haemodiafiltration (CVVHDF, 15 mL/kg/h + 15 mL/kg/h). METHODS Patients requiring(More)
Pharmacokinetic studies on ceftazidime, an aminothiazole cephalosporin with a wide spectrum of antibacterial activity, including activity against Pseudomonas aeruginosa, were performed in patients with nosocomial pneumonia. The concentration-time profiles of ceftazidime in plasma, urine, and bronchial secretions of 12 patients were investigated after(More)
We retrospectively analyzed amikacin pharmacokinetics in 19 critically ill patients who received amikacin intravenously. Fourteen subjects (577 serum amikacin concentrations, 167 urine measurements) were studied to obtain data for population modeling, while 5 patients (267 serum amikacin concentrations, 68 urine measurements) were studied for the assessment(More)
Low peak plasma concentrations (Cmax) of amikacin and gentamicin are reported in intensive care unit (ICU) patients after administration of the first dose. The present study aimed to describe the proportion of ICU patients in whom an adequate Cmax was achieved throughout the course of therapy. Septic ICU patients with an indication for intravenous amikacin(More)
