Bhalla AK, et al. - Researchers performed a retrospective cohort study of children with pediatric acute respiratory distress syndrome to assess the link between inhaled nitric oxide treatment and ICU mortality and 28-day ventilator-free days. They analyzed 499 children, with 143 (28.7%) receiving inhaled nitric oxide treatment. In pediatric acute respiratory distress syndrome, no improved mortality or ventilator-free days were achieved via treatment with inhaled nitric oxide. The treatment, however, may be associated with harm.
