RESUMEN
OBJECTIVE: To investigate the mortality and predictors of outcome of children with acute respiratory distress syndrome (ARDS) in pediatric intensive care unit (PICU). METHODS: ARDS cases were selected from the 12 018 patients admitted in 25 pediatric intensive care units in China from January 1 to December 31, 2004, aged 29 days to 14 years, using the Chinese Pediatric Critical Index of Severity (PCIS) and American Guidelines for Admission and Discharge Policies for PICU. ARDS was diagnosed according to the 1994 American-European Consensus Conference criteria. RESULTS: 105 of the 12 018 patients (1.44%) were diagnosed as with ARDS. The overall mortality of ARDS was 61.0% (64/105), 9 times as high as that of the 7269 severe cases in PICU. Logistic regression analysis showed that infiltration shadows in 2 - 3 quadrants, pediatric critical illness score (PCIS), and partial pressure of carbon dioxide (PaCO2) at the onset of ARDS were independently associated with the mortality. CONCLUSION: ARDS has a high risk of death, and the infiltration shadows in 2-3 quadrants, PCIS, and PaCO2 are independently associated with mortality.
