Inhaled Nitric Oxide Study for Respiratory Failure in Newborns

Summary

Respiratory failure in term newborns is associated with increased rates of death and long-term neurodevelopmental problems. This large international multicenter trial randomized newborns who had failed to respond to intensive care, including high levels of ventilator support, to receive either inhaled nitric oxide (iNO) or 100 percent oxygen to test whether iNO would decrease their risk of dying or requiring temporary lung bypass. Infants were followed during their initial hospitalization; their outcome was assessed at 18 to 24 mos of age.
