Clinical Trial Summary

The purpose of this study was to determine the effect of aerosolized colistin on to ventilated patients with carbapenem-resistant gram negative bacteria pneumonia. We hypothesize that adjunct aerosolized colistin, which achieve high drug concentrations in the airway, would more effectively treat the penumbra.

Description:

To treat respiratory infection of patients with mechanical ventilation, greater systemic antibiotic dose is required through the patient's venous injection. In this trial, patients with arbapenem-resistant gram negative bacteria pneumonia (CRGNB)were assigned to adjunct aerosolized colistin delivered by a jet nebulizer or a vibrating mesh nebulizer comparing to or standard intravenous injection by a randomizing protocol.

Need for a systemic antibiotic was determined by the clinical physician. Comparisons were made between standard care and study drug for their effects on bacteria eradiation, incidence of nephrotoxicity, and oxygenation.
