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...

Muscle protein synthesis (MPS) rate is determined conventionally by obtaining two or more tissue biopsies during a primed, continuous infusion of a stable isotopically labeled amino acid. The purpose of the present study was to test whether tracer priming given as a flooding dose, thereby securing an instantaneous labeling of the tissue pools of free tracee amino acids, followed by a continuous...

Two infants with short bowel syndrome were successfully weaned from total parenteral alimentation by means of a continuous intragastric infusion through a gastrostomy of a dilute elemental diet. Each patient had received TPA for 9 and 3 months, respectively, and had failed to thrive while receiving other therapeutic formulas. Gradual transition to bolus feeling was accomplished in each infant a...

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...

INTRODUCTION Despite increasing chemoradiotherapy treatment, there is a paucity of information regarding the effects of radiation exposure on ambulatory infusion pumps used to deliver chemotherapy or other essential medications. The aim of this overview is to present the available evidence on this subject, heighten awareness within the clinical community, provide considerations for minimizing p...

The aim of the present study was to compare the amount of motor block produced by different loading doses of ropivacaine and bupivacaine when delivered in a dilute solution with added opioid. Sixty-eight healthy term primigravid parturients were randomized to receive an initial bolus dose of 10 mL of 1 of the following: 0.25% bupivacaine (high bupivacaine), 0.25% ropivacaine (high ropivacaine),...

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...
