Nosocomial pneumonia causes significant morbidity and mortallity in hospital inpatients. The risk of nosocomial pneumonia is greatest in Medical lntensive Care Units, particulary in intubated and mechanically ventilated patients (20- 67%). Riskfactors are consideredfor ali hospi­tal inpatients, for those patients that were ad­mitted in Medical lntensive Care Units and for those who were mechanically ventilated. The di­agnosis typically requires the appearance of a new infiltrate on the chest X-ray, fever, leucocyto­sis and purulent secretions occurring more than 48 hours after admission. The differential diag­nosis of fever and/or densities on chest radio­ graphs are considered Pseudomonas aeruginosa is the most common pathogen (16-31%), with Sta­phylococcus aureus the second pathogen most commonly encountered (8-20%). The treatement is with supportive measures and antimicrobial therapy, that is often empirical. lf Pseudomonas aeruginosa is suspected, consider empirical the­rapy. The duration of antibiotic therapy can be 21 days and it depends on the severity ofilness, alterations on the chest X-ray and the pathogen.
