Acute respiratory distress syndrome in children: a 10 year experience.
BACKGROUND
Acute respiratory distress syndrome is a well-recognized condition resulting in high permeability pulmonary edema associated with a high morbidity.


OBJECTIVE
To examine a 10 year experience of predisposing factors, describe the clinical course, and assess predictors of mortality in children with this syndrome.


METHODS
The medical records of all admissions to the pediatric intensive care unit over a 10 year period were evaluated to identify children with ARDS. Patients were considered to have ARDS if they met all of the following criteria: acute onset of diffuse bilateral pulmonary infiltrates of non-cardiac origin and severe hypoxemia defined by < 200 partial pressure of oxygen during > or = 6 cm H2O positive end-expiratory pressure for a minimum of 24 hours. The medical records were reviewed for demographic, clinical, and physiologic information including PaO2/forced expiratory O2, alveolar-arterial O2 difference, and ventilation index.


RESULTS
We identified 39 children with the adult respiratory distress syndrome. Mean age was 7.4 years (range 50 days to 16 years) and the male:female ratio was 24:15. Predisposing insults included sepsis, pneumonias, malignancy, major trauma, shock, aspiration, near drowning, burns, and envenomation. The mortality rate was 61.5%. Predictors of death included the PaO2/FIO2, ventilation index and A-aDO2 on the second day after diagnosis. Nonsurvivors had significantly lower PaO2/FIO2 (116 +/- 12 vs. 175 +/- 8.3, P < 0.001), and higher A-aDO2 (368 +/- 28.9 vs. 228.0 +/- 15.5, P < 0.001) and ventilation index (43.3 +/- 2.9 vs. 53.1 +/- 18.0, P < 0.001) than survivors.


CONCLUSIONS
Local mortality outcome for ARDS is comparable to those in tertiary referral institutions in the United States and Western Europe. The PaO2/FIO2, A-aDO2 and ventilation index are valuable for predicting outcome in ARDS by the second day of conventional therapy. The development of a local risk profile may allow early application of innovative therapies in this population.
