Nosocomial pneumonia: Current etiology and impact on antimicrobial therapy
Abstract
Nosocomial pneumonia is an infection with high clinical impact and high morbimortality in which Pseudomonas aeruginosa plays a priority role, especially in the critically ill patient. Conventional antipseudomonal treatments, historically considered as standard, are currently facing important challenges due to the increase of antimicrobial resistance. In recent years, new antimicrobials have been developed with attractive sensitivity profiles and remarkable efficacy in clinical scenarios of nosocomial pneumonia including bacteremia, mechanical ventilation, infections with multidrug-resistant organisms or situations of therapeutic failure. This new evidence underscores the need to update current clinical guidelines for the antimicrobial treatment of nosocomial pneumonia, especially in the most critically ill patients.
