Prepared Endotracheal Tubes: Are They a Potential Source for Pathogenic Microorganisms?

Abstract

Prepared endotracheal tubes (PETTs) are back-up airway equipment to be used in the case of a difficult intubation. A short PETT shelf life because of unknown safe storage time results in significant budget costs. This blinded, controlled study examined the pathogenic potential of PETTs in the operating room environment.
