C. R. Bard Identifier:
First received: September 6, 2005
Last updated: January 14, 2017
Last verified: January 2017
The purpose of this study is to determine if the use of a silver-coated endotracheal tube (ETT) can reduce the incidence and/or delay the time of onset of VAP when compared to a non silver-coated ETT in patients who have been mechanically ventilated for >= 24 hours.

Respiratory Failure
Device: silver salts coated endotracheal tube
Device: uncoated endotracheal tube

Detailed Description:

Nosocomial pneumonia is the leading cause of death from hospital-acquired infections.Ventilator associated pneumonia (VAP) develops in a significant percentage of patients who have been ventilated for at least 48 hours, and is associated with high morbidity, mortality,and financial costs. Silver is a well-characterized antimicrobial agent, and is the active agent in multiple medical products used to reduce or control infection. Bard has developed a proprietary antimicrobial ETT, manufactured with a hydrophilic coating containing a fine dispersion of silver salts.

This study compare the incidence and time to onset of VAP in patients intubated for >=24 hours with a proprietary silver-coated ETT versus those intubated for >= 24 hours with a standard non-coated ETT.
