OBJECTIVE: To determine the frequency, etiology, and risk factors of @entity2489 ( @entity2489 ) and purulent tracheobronchitis (TBX) in @entity1 who have undergone heart surgery. To study the predictive role of systematic surveillance cultures. DESIGN: Prospective study. SETTING: Heart surgery intensive care unit. @entity1 : Intubated heart surgical @entity1 . INTERVENTIONS: Systematic tracheal aspirate and protected brush catheter cultures of all intubated @entity1 . MEASUREMENTS AND MAIN RESULTS: Studied were the frequency of lower @entity1729 in ventilated @entity1 and the role of surveillance cultures. The frequency of @entity2489 was 7.87% (34.5 per 1,000 days of mechanical ventilation), and the criteria for purulent tracheobronchitis was fulfilled by 8.15% of @entity1 (31.13 per 1,000 days of mechanical ventilation). After multivariate analysis, the variables independently associated with the development of @entity1729 were @entity6220 (relative risk [RR] = 4.7), @entity1066 (RR = 3.6), New York Heart Association score >/=3 (RR = 4), need for mechanical circulatory support (RR = 6.8), duration of mechanical ventilation >96 hrs (RR = 12.3), and reintubation (RR = 63.7). Mortality in our study was as follows: @entity2489 @entity1 , 57.1%; purulent tracheobronchitis @entity1 , 20.7%; colonized @entity1 , 11.5%; and noncolonized @entity1 , 1.6%. Regular surveillance cultures were taken from all ventilated @entity1 to assess the anticipative value of the cultures in predicting @entity1729 . A total of 1,626 respiratory surveillance samples were obtained. Surveillance cultures effectively predicted only one episode of @entity2489 and one of tracheobronchitis. CONCLUSIONS: @entity1 undergoing heart surgery have a high frequency of @entity2489 . @entity2489 is associated with a poor prognosis. In this study, surveillance cultures failed as an anticipative diagnostic method.
