Cases of ventilator-associated pneumonia (VAP) were investigated in a cardiothoracic surgery postoperative intensive care unit between 1 January 1999 and 31 December 1999. A total of 1716 patients who had undergone cardiothoracic operations and admitted to the intensive care unit (ICU) were included in the study. Patient- and laboratory-based prospective surveillance of VAP was done along with other hospital-acquired infections. ⋯ No causative micro-organism was identified in 2% of cases. The same bacteria were isolated in both blood and endotracheal aspirate cultures in 10 of 46 pneumonia cases (22%). The crude mortality rate of VAP was calculated as 30%
