Bacterial colonization of nanomodified endotracheal tubes in a bench top airway model

Bacterial colonization of nanomodified endotracheal tubes in a bench top airway model is reported. The airway model designed for this purpose contained two polymethylmethacrylate chambers, an anterior chamber modeling the oropharynx and a posterior dual chamber simulating the lungs, connected by a tube representing the trachea. Chemical etching techniques can create nano-rough surface features on PVC that suppress S. aureus growth in both static and dynamic studies.
