OBJECTIVE: To examine the effect of furosemide on hypertension and edema in patients with pre-eclampsia experiencing high cardiac output.
METHODS: The present cohort study enrolled patients with pre-eclampsia who were admitted to the pregnancy pathology unit of the Department of Obstetrics and Gynecology, University of Pécs, Hungary, between January 1 and December 31, 2015. Eligible patients had singleton pregnancies with no fetal anomalies, high blood volume, visible edema, and a hematocrit concentration below 37 L/L. Blood pressure was measured and impedance cardiography was used to determine cardiac output for all patients before they received a 40-mg dose of furosemide; after 60 minutes blood pressure and cardiac output were measured again.
RESULTS: The study enrolled 14 patients. Lower cardiac output (P=0.002), systolic blood pressure (P=0.002), and diastolic blood pressure (P=0.002) were recorded after furosemide administration, with patient heart rates remaining stable.
CONCLUSION: The heart-rate stability suggests that the change of cardiac output was due to a decrease in blood volume. These data suggest that diuretics could be useful in the management of late-onset pre-eclampsia, indicating that an increase in water retention could play a role in the development of late-onset pre-eclampsia.
