Hypoxanthine arabinoside pharmacokinetics were measured during an adenine arabinoside continuous intravenous infusion and during hemodialysis in a patient with renal failure. Therapeutic guidelines for adenine arabinoside in renal failure are provided based on an elimination half-life of 4.7 h and a plasma clearance of 87.9 ml/min for the hypoxanthine metabolite.

The pharmacokinetic-pharmacodynamic profile of a fixed 6-g daily continuous intravenous infusion of ceftazidime was assessed in 20 febrile neutropenic patients with acute myeloid leukemia. Mean steady-state ceftazidime concentrations averaging 40 mg/liter from day 2 on ensured maximized pharmacodynamic exposure (values close to four to five times the MIC breakpoint against Pseudomonas aeruginos...

A continuous intravenous infusion was used to assess the tissue penetration of cefazolin (14 subjects) and cefuroxime (15 subjects) in orthopedic surgery patients. Subjects were randomly assigned to receive a continuous intravenous infusion of cefazolin (mean, 178.6 mg/h) or cefuroxime (mean, 330.0 mg/h) at a rate estimated to achieve a target steady-state total concentration of 50 micrograms/m...

BACKGROUND AND OBJECTIVES Remifentanil is the newest opioid for anesthetic procedures. This study aimed at reviewing the literature, with emphasis on information of clinical interest published from January 2000 to December 2002. CONTENTS Major remifentanil studies are described and grouped by areas of interest for clinical anesthesia. Issues such as recommended dose, equipment and their corre...

The pharmacokinetics of grepafloxacin were determined in albino and pigmented rabbits following a single 10 mg/kg intravenous administration. The penetration of grepafloxacin into various ocular tissues was also determined after continuous intravenous infusion in both types of animal. Grepafloxacin showed a bicompartmental model of distribution in both pigmented and albino rabbits with signific...

The objective of the present study was to determine the efficacy of prophylactic administration of gabexate for the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, hyperamylasemia and pancreatic pain. Patients scheduled for ERCP were randomized into two groups in a double-blind manner: the patients in the gabexate group were treated with continuous intrave...

IV drug infusion has the potential for dosing errors, which arise from complex interactions between carrier flows and the infusion set dead volume. We computed the steady-state mass of drug stored in the infusion set dead volume, using phenylephrine as a model compound. The mass of drug in the dead volume increases with stock drug concentration and desired dose but decreases with carrier flow r...

We have examined the effects of intravenous infusion of recombinant human tumour necrosis factor (rh-TNF) on serum activity of phospholipase A(2) (PLA(2)) in patients with malignancies. Nine patients received a 24 h continuous intravenous infusion ranging from 1.0 x 10(5) U/m(2) to 3.0 x 10(5) U/m(2); 14 patients received a 5 day continuous intravenous infusion ranging from 0.5 x 10(5) U/m(2)/d...

conclusions intravenous administration of paracetamol immediately after knee arthroscopy improved postoperative pain, decreased analgesic administration, maintained stable hemodynamic parameters, had no complications related to opiates, no nausea and vomiting, and increased patient satisfaction and comfort in comparison to pca with morphine. results there was no significant difference regarding...
