Study summary

This is a single site pilot randomized, controlled, trial randomizing patients with PE with severe features to one of 2 groups:

  • 24 hours of postpartum magnesium sulfate (current arbitrary standard of care)
  • Using the Cheetah® device to aid in an individualized duration of magnesium sulfate.

Study arms

  • Experimental
    Cheetah® non-invasive cardiac monitoring system

    Using the Cheetah® device to aid in an individualized duration of magnesium sulfate based on reduction in Systemic Vascular Resistance (SVR), up to a maximum of 24 hours postpartum.

    Device: Cheetah® non-invasive cardiac monitoring system

  • Other
    Standard of care

    24 hours of postpartum magnesium sulfate (current arbitrary standard of care)

    Other: Standard of care

Interventions

  • DeviceCheetah® non-invasive cardiac monitoring system

    Cheetah® non-invasive cardiac monitor system will be used to individually determine the duration of magnesium sulfate postpartum (guided by timing of reduction in Systemic Vascular Resistance (SVR))

  • OtherStandard of care

    24 hours of postpartum magnesium sulfate

What researchers measure

Primary outcomes

  1. Duration of Magnesium Sulfate Use in the Postpartum Period Defined as the Duration in Hours Between Delivery and Discontinuation of Magnesium Sulfate.

    Time frame: up to 24 hours postpartum

Secondary outcomes

  1. Composite of Postpartum Adverse Outcomes

    any of the following: use of acute anti-hypertensive medications for persistently severe range blood pressure (defined as \>160/110 persistent after 15 min), need for more than one dose of acute anti-hypertensive medications, need to restart Mg (for persistent neurological symptoms), postpartum readmission for PE, as well as the development of pulmonary edema, HELLP, or eclampsia

    Time frame: up to 4 weeks after delivery

  2. Evaluating Incidence of Need to Restart Magnesium Sulfate

    Time frame: up to 1 week postpartum

  3. Evaluating Number of Participants With Hospital Readmission for Preeclampsia

    Time frame: up to 4 weeks postpartum

  4. Use of Acute Anti-hypertensive Medications

    Time frame: Up to 5 days after delivery

  5. Need for More Than 1 Dose of Anti-hypertensive Medication

    Time frame: Up to 5 days after delivery
