The aim of the study was to compare colonization rates of the ventilator tubings, frequency of ventilator associated pneumonia (VAP) and mortality in the intensive care unit (ICU) in mechanically ventilated patients for whom closed or open tracheal aspiration systems were used in a randomized fashion.

The study was started in 1 April 2000 and patients who received mechanical ventilation (MV) for at least 48 hours were included.

The results (mean ± SE or n [%]) of the analysis of the first 7 months are presented in the Table.

*n = 19 in the open aspiration system group and n = 17 in the closed aspiration system group.

In conclusion, in the preliminary analysis of this study the rate of colonization tended to be increased in the closed aspiration system group when compared with the open aspiration system group. However, there was no difference between the groups in terms of the development of VAP and mortality in the ICU.
