Abstract/OtherAbstract:
OBJECTIVE: Respiratory syncytial virus (RSV) infection can progress to acute respiratory distress syndrome (ARDS) in infants. ARDS is a life-threatening condition that is characterized by severe hypoxemia, defined as PaO2 /FiO2 ratio <300 mmHg. This ratio is used in many trials as the sole oxygenation criterion for ARDS. Recently, however, it has been shown in adults with ARDS that FiO2 , independently of the PaO2 /FiO2 ratio predicts mortality. Because epidemiology and outcome of ARDS differ strongly between children and adults, we determined if FiO2 on admission (baseline FiO2 ) independently predicted the duration of mechanical ventilation (MV) and length of stay (LOS) in the pediatric intensive care unit (PICU) in infants with RSV-induced ARDS.
DESIGN: Retrospective observational study.
SETTING: A 14-bed pediatric intensive care unit.
PATIENTS: One hundred twenty-nine mechanically ventilated infants with RSV-induced ARDS.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Independent predictors for outcome, including baseline FiO2 and PEEP, were analyzed using the cox regression model. Endpoints were duration of MV and LOS in the PICU. A higher baseline FiO2 was independently associated with a longer duration of MV (HR 0.12, CI 0.02-0.87, P = 0.036) and increased LOS in the PICU (HR 0.09, CI 0.01-0.57, P = 0.023). Neither baseline PEEP nor PaO2 /FiO2 ratio correlated with outcome.
CONCLUSIONS: FiO2 level independently predicted outcome in infants with RSV-induced ARDS, whereas both PEEP and the PaO2 /FiO2 ratio did not. This suggests that FiO2 should be taken into account in defining disease severity in infants with RSV-induced ARDS. Pediatr Pulmonol. © 2013 Wiley Periodicals, Inc.
