In Utero Magnesium Sulfate Exposure: Effects on Extremely-Low-Birth-Weight Infants (MgSO4)

September 22, 2017 updated by: NICHD Neonatal Research Network

In Utero Magnesium Sulfate Exposure: Effects on Extremely-Low-Birth-Weight (ELBW) Infants

This study examined the effect of magnesium sulfate (MgSO4) exposure on adverse outcome in extremely low birth weight (ELBW) infants. For infants included in the NICHD Neonatal Research Network Generic Database whose mothers were given prenatal MgSO4, data were prospectively collected on maternal/infant conditions and magnesium exposure (including indications, timing and duration of exposure).

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Retrospective studies suggested that the risk of cerebral palsy and intraventricular hemorrhage (IVH) in extremely premature infants of mothers given magnesium sulfate (MgSO4) may be reduced. The purpose of this study was to examine the effects of MgSO4 exposure on adverse outcomes in extremely low birth weight (ELBW) infants. For infants included in the NICHD Neonatal Research Network Generic Database, data were prospectively collected on maternal/infant conditions and MgSO4 exposure (including indications, timing and duration of exposure).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 2 weeks (CHILD)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

All infants with birth weights 401 through 1500 grams admitted to the NICU within 14 days of age are eligible for the study. In addition, all inborn, liveborn infants in the same weight range (401-1500 gms) who die prior to admission to the NICU are enrolled posthumously.

Description

Inclusion Criteria:

  • Infants born in NRN Centers with a birth weight of 401-1,500g

Exclusion Criteria:

  • None

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Incidence of Intraventricular Hemorrhage
Time Frame: Hospital discharge 120 days of life
Hospital discharge 120 days of life

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Incidence of cerebral palsy
Time Frame: 18-22 months corrected age
18-22 months corrected age

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
