Monitorización de la vacomicina en administración intraperitoneal en pacientes sometidos a diálisis peritoneal continua ambulatoria
Objective: To validate a pharmacokinetic model of the treatments with intraperitoneal vancomycin applied to patients on continuous ambulatory peritoneal dialysis with bacterial peritonitis. Methods: To carry out a prospective study divided in 2 cohorts: the first one including ten patients of 56 ± 14 years and 65 ± 5 kg, and the second one with 10 patients (12 episodes of peritonitis) aged 52 ± 13 years and 64 ± 8 kg. The treatment consists of administering and retaining for 6 h in the peritoneal cavity a solution containing 2 g of vancomycin and 1 g of ceftazidime into 2 l of ‘‘dialysis solution’’. After the antibiotic administration, blood samples were obtained at 4, 6, 8, 10, 24, 48 and …
Estabilidad en suero fisiológico del busulfán intravenoso en un envase de poliolefinas
Introduction: Although it has been used orally, the variability in its absorption and the risk of causing vomiting has lead to a push towards the intravenous use of bulsulfan. This study looks at the stability of 60 mg of busulfan, in fixed volumes of 250 mL (0.24 mg/mL) and 500 mL (0.12 mg/mL) of serum and different conservation conditions, in a new plastic pack made from polyolefin/polyamide laminates. Material and methods: High-efficiency liquid chromatography with ultraviolet detection was used to determine the concentration of busulfan derivate with sodium diethyldithiocarbamatetrihydrate. Stability was assessed for both concentrations; refrigerated and at room temperature, using the t…
Farmacocinética del metronidazol y la gentamicina en dosis única preoperatoria para profilaxis antibiótica quirúrgica en cirugía colorrectal
Objective: To describe, in patients undergoing colorectal surgery (CRS), the pharmacokinetics of a single, prophylactic preoperative dose of 1,500 mg of metronidazole plus 240 mg gentamicin and measure its efficacy in accordance with the accepted pharmacodynamic and microbiological parameters. Method: Thirty-six patients undergoing CRS agreed to participate in the study. Three blood samples were taken from each. Cmax 15 minutes after finishing the infusion of the mixture, CfinIQ on finishing the surgery, and Cmin between 12 and 24 hours post-administration. The concentrations of metronidazole and gentamicin in each simple were measured and the pharmacokinetic parameters were estimated (dV- …
Stability in physiological saline of intravenous busulfan in a polyolefin pack
Abstract Introduction Although it has been used orally, the variability in its absorption and the risk of causing vomiting has lead to a push towards the intravenous use of busulfan. This study looks at the stability of 60 mg of busulfan, in fixed volumes of 250 mL (0.24 mg/mL) and 500 mL (0.12 mg/mL) of physiological saline and different conservation conditions, in a new plastic pack made from polyolefin/polyamide laminates. Material and methods High-performance liquid chromatography with ultraviolet detection was used to determine the concentration of busulfan derivate with sodium diethyldithiocarbamate trihydrate. Stability was assessed for both concentrations; refrigerated and at room t…
