Although inhaled nitric oxide (iNO) has proved effective in improving oxygenation in late preterm infants, studies of its efficacy in infants born at or before 34 weeks have produced variable and contradictory findings. Now a systematic review of findings from 22 trials of iNO use in 3,461 early preterm infants concludes that the evidence does not support routine use of iNO to treat these infants. The review, which appears in Pediatrics, examined 14 randomized, controlled trials (RCTs), 7 follow-up studies, and 1 observation study.
