NCT04912726

Brief Summary

Sildenafil is currently approved for the management of pulmonary hypertension of the newborn, with the availability of intravenous presentation it has been seen that the severity condition has already established, many times these patients do not have the adequate clinical response and there are no studies to date that evaluate the efficacy and safety of the same when it is started early in these patients, therefore we plan a randomized clinical trial to determine the efficacy and safety of the administration of intravenous sildenafil for early management of newborns with persistent pulmonary hypertension of the newborn.

Outcome Measures

Primary Outcomes (1)

  • 20% decrease in estimated pulmonary artery pressure

    Evaluate the efficacy in lowering the estimated pulmonary artery pressure by 20% and improved survival with early use of intravenous sildenafil at a loading dose of 0.4 mg / kg in 3 hours, followed by continuous infusion at 1.6 mg / kg / day versus conventional treatment plus placebo in neonates with persistent pulmonary hypertension of the newborn.

    7 days

Secondary Outcomes (3)

  • Duration of mechanical ventilation

    7 days

  • Duration of inotropic therapy

    7 days

  • Adverse events

    7 days

Study Arms (2)

Intervention

EXPERIMENTAL

The intervention group will receive intravenous sildenafil loading dose of 0.4 mg / kg in 3 hours and continue in continuous infusion at 1.6 mg / kg / day (0.067 mg / kg / h).

Drug: Sildenafil Injectable Product

Placebo

NO INTERVENTION

The control group will receive placebo at the same loading dose and infusion with 0.9% saline solution plus standard management under the unit protocol immediately after the echocardiographic diagnosis.

Interventions

The intervention group will receive intravenous sildenafil loading dose of 0.4 mg / kg in 3 hours and continue in continuous infusion at 1.6 mg / kg / day (0.067 mg / kg / h).

Also known as: Intravenous sildenafil

Eligibility Criteria

AgeUp to 10 Days
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Newborns with gestational age ≥ 34 weeks and less than 10 days old, from the delivery room, joint accommodation, surgery at the Niño Jesus Hospital and referred from other institutions with an echocardiographic diagnosis of persistent pulmonary hypertension of the newborn. A diagnosis of persistent pulmonary hypertension of the newborn will be made if any of the following criteria are identified in the absence of cyanotic congenital heart disease by echocardiography: Tricuspid regurgitant jet with a pressure gradient ≥ 2/3 of systemic systolic blood pressure; intraventricular septum that flattens or slopes into the left ventricular cavity; bidirectional or right-to-left flow through patent ductus arteriosus; pulmonary artery acceleration time \<40 milliseconds

You may not qualify if:

  • Congenital heart disease or fatal congenital anomalies
  • Oxygenation Index (IO) \> 15
  • No parental consent

Masking Details
Assignment concealment will be ensured using sealed and sequenced opaque (dark) sealed envelopes containing the assignments. An investigator will carry out the assignment, write down the assignment number in a specific format, seal the opaque envelope and number it consecutively. These envelopes will be stored in the neonatal intensive care unit of the hospital child jesus where the study will be carried out. Once a subject has met the inclusion criteria, the neonatal intensive care unit pharmacy service will be notified, staff not participating in the study who will make a phone call to the investigator so that he can assign the label number to the new subject who I enter the study, the pharmacy shift personnel are in charge of labeling and delivering the product to the nursing staff. The active product intravenous sildenafil and the placebo are packaged in identical burette, the burette content is visible and the coloration is transparent.
