Outcome of Respiratory Failure: A Case-Control StudyDivision of Critical Care, Cook Children's Medical Center, Fort Worth, Texas

Division of Critical Care & Emergency Medicine, Department of Pediatrics, Emory University School of Medicine, Atlanta, GA Despite the availability of ECMO (extracorporeal membrane oxygenation) services for nearly a decade, the criteria for the institution of ECMO for pediatric respiratory failure are still not clearly defined. Therefore, a chart review was performed on children who were mechanically ventilated more than 48 hours in 1989-1990 in order to evaluate possible predictors of death from pediatric respiratory failure. Twenty-three children died as a consequence of respiratory failure. Nonsurvivors in both years were compared with the 78 survivors in 1990, and potential predictors were subjected to multivariate analysis. After 4 days of mechanical ventilation, an alveolar-arterial oxygen gradient (AaD02) greater than 400 torr (53.3 kPa) was a weak predictor of death due to respiratory failure, and yet an AaD02 less than 400 torr (53.3 kPa) was a stronger predictor of survivability. Combination of variables did not yield a better predictor than any single variable. Early prediction of mortality from respiratory failure in this population was not found.
