Prognostic value of the oxygenation index to predict survival and timing of surgery in infants with congenital diaphragmatic hernia

Retrospective study evaluating oxygenation index measurements in the first 48 hours after birth as predictors of 30-day mortality and optimal surgical timing in infants with antenatally diagnosed CDH. Analysis compares mean versus best OI on day 1 and correlates serial OI values with surgical outcomes, ventilation duration, and hospital length of stay.
