Persistent Fetal Circulation Persistent Pulmonary Hypertension of the Newborn PPHN | Drug: Nebulized Magnesium Sulfate Drug: Intravenous Magnesium Sulfate | Phase 1 Phase 2 |
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 28 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Two groups of neonates with PPHN
|
Masking: | Triple (Participant, Care Provider, Outcomes Assessor) |
Masking Description: | Each neonate was assigned a unique identification number. Pharmacy filled the active and placebo preparations in similar containers with sealed code for identification. Participants' families, treating clinicians, nurses, echocardiographers, and data collectors were unaware of group assignment and drug/placebo therapy. |
Primary Purpose: | Treatment |
Official Title: | Nebulized Magnesium Sulfate for Treatment of Persistent Pulmonary Hypertension of The Newborn |
Actual Study Start Date : | November 1, 2017 |
Actual Primary Completion Date : | July 1, 2020 |
Actual Study Completion Date : | August 1, 2020 |

---|---|
Experimental: NebMag
Neonates with PPHN receiving nebulized magnesium sulfate and intravenous placebo
|
Drug: Nebulized Magnesium Sulfate
Nebulized magnesium sulfate (isotonic solution) 256 mg every 15 minutes |
Active Comparator: IVMag
Neonates with PPHN receiving intravenous magnesium sulfate and nebulized placebo
|
Drug: Intravenous Magnesium Sulfate
Intravenous magnesium sulfate 200 mg/kg over 30 minutes, followed by a continuous infusion at a rate of 50 mg/kg/hour |
- Oxygenation index (OI) [ Time Frame: At baseline to 2, 6, 12, and 24 hours following study drug administration. ]
Change in oxygenation index (OI) calculated by the classic formula:
OI = [(FiO2 * MAP) / PaO2]
FiO2 expressed in %; MAP in cmH2O/mmHg; and PaO2 in mmHg
- Mean arterial blood pressure (MABP) [ Time Frame: At baseline to 2, 6, 12, and 24 hours following study drug administration. ]Changes in mean arterial blood pressure
- Serum magnesium level [ Time Frame: At baseline to 12 hours after study drug adminstration ]Changes in serum magnesium level
- Vasoactive Inotropic Score (VIS) [ Time Frame: At baseline to 2, 6, 12, and 24 hours following study drug administration ]
Changes in VIS calculated by the classic formula:
VIS = dopamine dose (µg/kg/min) + dobutamine dose (µg/kg/min) + 100 × epinephrine dose (µg/kg/min) + 100 × norepinephrine dose (µg/kg/min) + 10 × milrinone dose (µg/kg/min) + 10,000 × vasopressin dose (U/kg/min)
