Nitro Oxide Inhalation Continued With Sildenafil on Neonatal Persistent Pulmonary Hypertension

June 14, 2011 updated by: Third Military Medical University

Compare of Continued Nitro Oxide Inhalation and Nitro Oxide Inhalation Continued With Oral Sildenafil on Treatment of Neonatal Persistent Pulmonary Hypertension

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: NOS
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 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.
Placebo Comparator: NO
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
NO inhalation was performed as the only treatment for PPHN during the whole course.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
persistent normal pulmonary artery pressure
Time Frame: 96 hours
The pulmonary artery pressure returned back to a normal level(<30mmHg) and last over 48 hours.
96 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recover without complication
Time Frame: 1 month after therapy

To ensure the safety of the therapies, brain and lung complications of the baby after PPHN is going to be observed 1 month after birth.

  1. incidence of pulmonary disease;(chronic lung disease)
  2. incidence of brain injury. (Hypoxic-ischemic encephalopathy)
  3. Heart structure change(right ventricle enlarge)
1 month after therapy
