About this study

Official title: Magnesium Sulfate Versus Placebo for Tocolysis in Preterm Premature Rupture of Membranes

Study compares the outcomes of women between 26 and 32 wks gestation with rupture of membranes. Women randomized to receive tocolysis with magnesium sulfate x 48 hrs or placebo of saline IV x 48 hrs. Antibiotics and antenatal steroids given to both groups.

Read the detailed description

The majority of studies of the effectiveness of tocolysis with PPROM were in the 1980s prior to the commmon usage of antenatal steroids and prophylactic maternal antibiotics. In most studies, tocolysis was not attempted prior to the onset of labor in this group of women. The ACOG Practice Bulletin of June 1998 concedes that the recommendation of tocolysis to permit administration of steroids and maternal antibiotics is based primarily upon consensus, not consistent scientific evidence.

The purpose of this study, which will randomize 128 subjects to tocolysis or no tocolysis, is to prospectively assess whether short term (48 hr) tocolysis affords benefit to women and babies between 26 and 32 weeks gestation with PPROM.

Subjects will be enrolled at 1-2 high risk hospitals in Chattanooga and Knoxville. All English and Spanish speaking women 18-45 years with PPROM and cervical dilation <4 will be eligible. Women with suspected intrauterine infection, positive fetal lung maturity, or > 6 hours tocolysis at time of admission will be excluded.

Both groups of women will receive continuous fetal monitoring, antibiotics, and antenatal steroids (if not previously administered). Both groups will be evaluated every 2-4 hours for fetal and maternal well being. Both groups will receive IVF at 125cc/hr, and the treatment group will be loaded with 4 grams of magnesium sulfate and receive maintainence dose of 2 grams/hr x 48 hrs.

    from start of study drug to maternal discharge from hospital

    Measured: 0 hours to > 168 hours

  3. neonatal ventilator days

    from delivery to 28 days of life

    Measured: 0 to 28 days

  4. neonatal early onset infection

    from delivery to 28 days of life

    Measured: 0 to 28 days

Questions about this trial

What is this clinical trial studying?

A study testing Magnesium sulfate in people with Preterm Premature Rupture of Membranes, run by Regional Obstetrical Consultants at 1 site in United States.

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 4 inclusion and 3 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: stopped early, as of the sponsor's last update on 19 Aug 2016. 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 United States. 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 was stopped early (reason given: enrollment proceeding too slowly). Results are not available in the source record.

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?

hours of latency to delivery (time frame: 0 hours to > 168 hours). 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 NCT00463736, which also lists 1 linked publication.

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 19 Aug 2016.
