Pharmacokinetics of Nebulized Amikacin in Patients With Pneumonia Undergoing Mechanical Ventilation

2014-07-24 14:14:02 | BioPortfolio

Summary

Inclusion of patients undergoing mechanical ventilation and presenting a pneumonia in order to determine serum pharmacokinetics of nebulized amikacin. The primary aim is to determine the dose of amikacin to be nebulized in order to observe amikacin serum concentrations close to but inferior to those observed after standart intravenous amikacin infusion.

Description

After inclusion, patients undergo intravenous infusion of 20 mg/Kg of amikacin with amikacin serum concentrations being monitored over the following 24 hours.

Randomization occures after this first amikacin infusion. Patients are randomized to group nebulized amikacin or intravenous amikacin. The three next days of the study patients recieve nebulized amikacin (or nebulized placebo) during mechanical ventilation and a placebo infusion (amikacin infusion in case of placebo nebulization) using a air driven jet nebulizer. Amikacin serum concentrations are monitored over 24 hours after each nebulization.

Patients are followed up during 10 days for safety and efficacy. The dose of amikacin to be nebulized is 60 mg/Kg for the first 6 patients (phase A), 80 mg/Kg for the next 6 patients (phase B) and 100 mg/Kg for the last 6 patients (phase C). Each phase is started after review of the results of the preceeding phase by an idependent safety and monitoring board.

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

Fluid propulsion systems driven mechanically, electrically, or osmotically that are used to inject (or infuse) over time agents into a patient or experimental animal; used routinely in hospitals to maintain a patent intravenous line, to administer antineoplastic agents and other drugs in thromboembolism, heart disease, diabetes mellitus (INSULIN INFUSION SYSTEMS is also available), and other disorders.

Immunoglobulin preparations used in intravenous infusion, containing primarily IMMUNOGLOBULIN G. They are used to treat a variety of diseases associated with decreased or abnormal immunoglobulin levels including pediatric AIDS; primary HYPERGAMMAGLOBULINEMIA; SCID; CYTOMEGALOVIRUS infections in transplant recipients, LYMPHOCYTIC LEUKEMIA, CHRONIC; Kawasaki syndrome, infection in neonates, and IDIOPATHIC THROMBOCYTOPENIC PURPURA.
