摘要
Nitric oxide given as an inhalation (INO) is a novel selective pulmonary vasodilator without effects on the systemic circulation. Preliminary observations indicated that INO treatment was associated with improvements in oxygenation in near-term newborn infants with hypoxic respiratory failure and persistent pulmonary hypertension of the newborn (PPHN). Subsequently, at least eight prospective randomized controlled trials evaluating the use of INO in the near-term neonate with hypoxic respiratory failure have been presented or published. A meta-analysis of these trials has provided evidence that INO improves the PaO2 in the INO-treated infants by 52.8 mm Hg (weighted mean difference) compared with controls (95% CI, 38.2, 67.4), and significantly decreases the oxygenation index by 16.9 compared with controls (95% CI, -22.2, -11.6). The incidence of death or need for ECMO is significantly reduced by treatment with INO, relative risk 0.71 compared to control (95% CI, 0.57, 0.87), with the majority of the improvement observed in the reduction in the need for ECMO. A single study of infants with congenital diaphragmatic hernia (CDH) did not show a benefit for early INO therapy, with treated infants having a greater requirement for ECMO (P = .043). At present, there are no long-term evaluations of infants who have received INO as part of these prospective trials. INO improves oxygenation and reduces the need for ECMO in the near-term hypoxic neonate, but further research is required to evaluate the ultimate safety and benefit of this therapy.
