About this study

Official title: The Effect Of Nebulizied Nitroglycerin As An Adjuvant Drug In Management Of Persistent Pulmonary Hypertension Of Newborns

This aim of the study is to evaluate the effect of nebulized nitroglycerin on echocardiographic (biventricular function, pulmonary artery pressure, PDA and PFO shunting and tissue doppler imaging) and clinical parameters (Oxygen saturation index, heart rate, blood pressure, mean airway pressure, ventilation setting) in patients with PPHN.

Being tested
Nebulized nitroglycerine as adjunctive therapy, conventional therapy for PPHN
Medical subject headings
Persistent Fetal Circulation Syndrome, Respiration Disorders

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Nebulized nitroglycerine as adjunctive therapyDrug

    Patients with PPHN will have nebulized nitroglycerine as adjunctive therapy

  • conventional therapy for PPHNDrug

    patients will receive sildenafil which is used routinely in management of PPHN in our unit, in addition to appropriate oxygenation and ventilation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Estimation of Pulmonary artery pressure (PAP)

    Systolic pulmonary artery pressure (SPAP) can be estimated by measuring the peak velocity of tricuspid valve regurgitation with the use of the modified Bernoulli's equation.

    • The estimation of SPAP by measuring TR is reliable and often equivalent to pressures measured in the catheter lab while using continuous wave Doppler. However, the accuracy depends on the quality of the acquired TR jet. An optimal quality TR jet shows a well demarcated envelope.
    • Right atrial pressure (RAP) is usually not measured, and a value of 3- 5 mmHg is generally assumed.

    Measured: first 7 days of life

  2. Right ventricular (RV) function in ml/kg/min

    • RV output and stroke distance in main pulmonary artery:
    • CSA (cm) (Cross sectional area of PV by long axis parasternal RV outflow view - 2D - immediately beneath pulmonary annulus - mid-systole - inner edge to inner edge) = π x (radius)2 ✓ VTI (cm) (Velocity Time Integral or Stroke Distance = Distance over which blood travels in once cardiac cycle → Long axis parasternal RV outflow view). 12. ✓ SV (ml/beat) (Stroke Volume = CSA x VTI).
    • Output (L/min.) COP = SV x HR.

    Measured: first 7 days of life

  3. Left ventricular (LV)function in ml/kg/min

    LV output and stroke distance in ascending aorta:

    • CSA (cm) (Cross sectional area of AV by long axis parasternal view - 2D - immediately beneath aortic annulus - mid- systole - inner edge to inner edge) = π x (radius)2. ✓ VTI (cm) (Velocity Time Integral or Stroke Distance = Distance over which blood travels in once cardiac cycle → Apical 5-chamber view).
    • SV (ml/beat) (Stroke Volume = CSA x VTI).
    • Output (L/min.) COP = SV x HR.

    Measured: first 7 days of life

Questions about this trial

What is this clinical trial studying?

A study testing Nebulized nitroglycerine as adjunctive therapy and conventional therapy for PPHN in people with Persistent Pulmonary Hypertension of the Newborn and Echocardiography, run by Alexandria University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Estimation of Pulmonary artery pressure (PAP) (time frame: first 7 days of life). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05741229, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2025.
