Answer

Answer

In 2 large randomized trials, iNO reduced the need for ECMO support by approximately 40%. Although these trials led to the US Food and Drug Administration (FDA) approving iNO as a therapy for PPHN, iNO did not reduce mortality, the length of hospitalization, or the risk of neurodevelopmental impairment. [4]

A randomized study showed that beginning iNO at an earlier point in the disease course (for an OI of 15-25) did not decrease the incidence of ECMO and/or death or improve other patient outcomes, including the incidence of neurodevelopmental impairment.

The use of iNO has not been demonstrated to reduce the need for ECMO in newborns with congenital diaphragmatic hernia. In these newborns, iNO should be used in non-ECMO centers to allow for acute stabilization, followed by immediate transfer to a center that can provide ECMO.
