Conditions

Preeclampsia With Severe Features

Keywords

preeclampsia with severe features, magnesium sulfate, Systemic Vascular Resistance, non-invasive cardiac monitoring

Brief 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.

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))
