Outcome predictors in nitric oxide treated preterm infants

Abstract

Our aim was to identify factors predictive of death in preterm infants in whom inhaled nitric oxide was administered in response to poor oxygenation (oxygenation index > or =15). Of the 23 (median gestational age 28 weeks, range 24-36) infants consecutively so treated, 15 died. Non-survival was commoner in infants with air leaks (12 of 12, P < 0.002) and/or a change in their oxygenation index of less than 30% in response to inhaled nitric oxide administration (P < 0.05).

Conclusion: In preterm infants given inhaled nitric oxide because of poor oxygenation, a diagnosis of airleak and a lack of initial response are predictive of death.
