Brief Summary:
The aim of this pilot randomized controlled blinded study is to evaluate the feasibility of using nebulized magnesium sulfate in the treatment of PPHN.

Condition or disease Intervention/treatment Phase
Persistent Fetal Circulation Persistent Pulmonary Hypertension of the Newborn PPHN Drug: Nebulized Magnesium Sulfate Drug: Intravenous Magnesium Sulfate Phase 1 Phase 2

Detailed Description:
The effectiveness and safety of nebulized magnesium sulfate (using isotonic solution in a dose of 1024 mg/hour) is compared with intravenous magnesium sulfate (200 mg/kg over 30 minutes, followed by 50 mg/kg/hour) in treating mechanically ventilated neonates with severe persistent pulmonary hypertension of the newborn.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 28 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Two groups of neonates with PPHN

  1. NebMag group: receive nebulized magnesium sulfate and intravenous placebo.
  2. IVMag group: receive intravenous magnesium sulfate and nebulized placebo.
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

Arm Intervention/treatment
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




Primary Outcome Measures :
  1. 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



Secondary Outcome Measures :
  1. 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

  2. Serum magnesium level [ Time Frame: At baseline to 12 hours after study drug adminstration ]
    Changes in serum magnesium level

  3. 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)
