Preeclampsia is a multisystem disorder that complicates approximately 5-8% of pregnancies. It is known that the clinical manifestations of preeclampsia are a result of widespread vasoconstriction. It is therefore thought that the onset of diuresis may signal a reversal of this vasoconstriction, and thus resolution of the disease. This retrospective cohort study was conducted at the University of Iowa Hospitals and Clinics (UIHC) to validate our diuresis criteria and determine if there was a trend for diuresis that was dependent on the type of preeclampsia. This study suggests that the diuresis curves for those women with mild preeclampsia and severe preeclampsia do not vary significantly after the first 5 hours We were able to separate the women with severe preeclampsia into two groups, one of which would have met our diuresis criteria prior to 24 hours and the other of which would not have met diuresis criteria at 24 hours post-delivery.
