Brief Summary

Nitro Oxide (NO) inhalation was recognized as an effect treatment of Neonatal Persistent Pulmonary Hypertension (PPHN), while the safety of NO long term application was under investigation. Several research suggested too much NO2 was generated in the lung after long term (\> 72h) use of NO inhalation, which cause bad effects on PS production. Sildenafil was proved to be effective to PPHN as NO. This medication has a similar clinical effect but need monitoring of blood pressure. The possible hypotension effect restrict the dosage of sildenafil, which limit the usage of sildenafil in severe PPHN. But we recommend sildenafil to The purpose of the study was to establish if NO continued with sildenafil has the same effect as single NO inhalation.

Outcome Measures

Primary Outcomes (1)

  • persistent normal pulmonary artery pressure

    The pulmonary artery pressure returned back to a normal level(\<30mmHg) and last over 48 hours.

    96 hours

Secondary Outcomes (1)

  • Recover without complication

    1 month after therapy

Study Arms (2)

NOS

EXPERIMENTAL

NO inhalation was performed in the first stage(\<48h) of PPHN, NO inhalation was replaced by sildenafil in the second stage(\>48h).

Drug: NO inhalation continued with sildenafil

NO

PLACEBO COMPARATOR

NO inhalation was performed during the whole treatment procedure of PPHN. There is no other methods given to treat PPHN during the therapy course.

Drug: NO inhalation

Interventions

NO inhalation was performed as the only treatment for PPHN during the whole course.

NO

NO inhalation was performed as the primary treatment for PPHN in the first 48 hours, NO inhalation will be replaced by sildenafil after 48 hours of therapy.
