Low-cost antiseptic-impregnated tracheostomy tube for the prevention of ventilator-associated pneumonia caused by multidrug-resistant bacteria: In vitro and pilot study in humans
Juliano Gasparetto, Leandro Bressianini Jurkonis, Leticia Ramos Dantas, Paula Hansen Suss, Felipe Francisco Tuon
Rev Argent Microbiol. 2024;56:359-63
Highlights

  • Ventilator-associated pneumonia (VAP) is a common nosocomial infection in the ICU.

  • Antiseptic-coated endotracheal tubes can potentially reduce the risk of VAP.

  • Microbiological tests showed significant inhibition of standard bacteria by the impregnated tubes.

  • The impregnated tubes showed effective antimicrobial activity, and no adverse events were observed.
