Prognostic indicators in congenital diaphragmatic hernia.
Congenital diaphragmatic hernia is associated with significant mortality and morbidity. The aim of this study was to compare a series of tests with respect to prediction of outcome. Tidal volume and compliance of the respiratory system (CRS) were measured preoperatively and on the first and second postoperative days. The maximum and modified ventilation indexes and the maximum Paco2 were noted for the first 6 hours of life and the first 6 hours postoperatively. In addition, it was recorded whether the stomach was within the ipsilateral hemithorax preoperatively. Twenty infants were studied (median gestational age, 38 weeks; range, 31 to 40), six of whom had a poor outcome, ie, they died or remained oxygen-dependent after 28 days. A CRS of less than 0.18 mL/cm H2O/kg was the most accurate predictor of poor outcome, with 66% sensitivity and 100% specificity. The authors conclude that lung function measurement are useful in the assessment of infants with congenital diaphragmatic hernia.
