Abstract
Objective
To investigate the prognostic factors in acute respiratory distress syndrome (ARDS) patients focusing on the use of prone positioning (PP).
Design and setting
Retrospective study conducted in an intensive care unit of a university hospital.
Patients
All consecutive mechanically ventilated ARDS patients surviving on day 7 after the diagnosis of ARDS.
Methods
The study included all ARDS patients who survived more than 7 days after ARDS diagnosis between January 1995 and December 2002. Demographic and respiratory variables were collected on day 1, and the management of ARDS was analyzed during the first 7 days (n=125). We performed a univariate analysis and a stepwise logistic regression analysis comparing survivors and nonsurvivors on day 28 and at 2 and 6 months.
Results
Mortality rates on day 28 and at 2 and 6 months were 21.6%, 32%, and 44% respectively. A SAPS II score less than 49, McCabe score, and the use of PP introduced in the first 7 days of ARDS management appeared to be independently correlated with a decrease in mortality.
Conclusions
The SAPS II score, the McCabe score, and use of PP are independently correlated with the outcome in ARDS patients.
