Implications of endotracheal tube biofilm in ventilator-associated pneumonia response: a state of concept.

Introduction: Biofilm in endotracheal tubes (ETT) of ventilated patients has been suggested to play a role in the development of ventilator-associated pneumonia (VAP). Our purpose was to analyze the formation of ETT biofilm and its implication in the response and relapse of VAP.

Methods: We performed a prospective, observational study in a medical intensive care unit.
