Primary Outcome Measures:
  • Undelivered With Resolution of Vaginal Bleeding and Contractions in First 48 Hours [ Time Frame: 48 hours after the randomization ]
    The primary outcome was the proportion of women undelivered at 48 hours with resolution of vaginal bleeding and uterine contractions.


Secondary Outcome Measures:
  • Gestational Age at Delivery (Weeks) [ Time Frame: Time of delivery ]
    Median gestational age at delivery (in full weeks)

  • Neonatal Apgar Score at 5 Minutes [ Time Frame: At 5 minutes after birth ]
    The median Apgar score at 5 minutes. Apgar score scale is from 0 to 10 with score 0 expressing the worst neonatal status and score 10 the best status.


Enrollment: 30
Study Start Date: March 2004
Estimated Study Completion Date: March 2018
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Magnesium Sulfate
Magnesium Sulfate 4 gram bolus, followed by 2 grams per hour
Drug: Magnesium Sulfate
Magnesium Sulfate 4 gram bolus, followed by a maintenance dose at 2 grams per hour. Rate increases up to 4 grams per hour may be administered per physician discretion.
Other Name: Active study drug
Placebo Comparator: Normal Saline
Normal Saline 4 gram bolus, followed by 2 grams per hour
Other: Normal Saline
Normal Saline infusion of 4 gram bolus, followed by 2 grams per hour with rate increases up to 4 grams per hour per physician discretion.
Other Name: Normal Saline infusion as placebo

Detailed Description:
We hope to learn if there is a difference in the efficacy of intravenous magnesium sulfate versus intravenous saline infusion in the resolution of vaginal bleeding and contractions in patients with a suspected placental abruption.
