Impedance cardiography facilitates differentiation of severe and superimposed preeclampsia from other hypertensive disorders.
OBJECTIVE
To determine if hemodynamic profiling using noninvasive impedance cardiography (ICG) reliably identifies the patient with severe (SPRE) or superimposed (SuPRE) preeclampsia.


METHODS
Late gestation hypertensive pregnant patients underwent immediate ICG evaluation. Findings were compared between patients subsequently achieving or not achieving American College of Obstetricians and Gynecologists criteria for SPRE or SuPRE.


RESULTS
Patients with severe disease were more likely to have depressed cardiac function and higher systolic blood pressure, mean arterial blood pressure, systemic vascular resistance, and thoracic fluid content compared to nonsevere hypertensive disease.


CONCLUSIONS
ICG hemodynamic profiling of late gestation hypertensive patients can rapidly and reliably identify those with SPRE or SuPRE.
