Objective: diuretics have the potential to reduce intravascular volume, decrease blood pressure The aim of our study is to evaluate the effectiveness of furosemide in postpartum patients with pre-eclampsia and chronic hypertension with superimposed pre-eclampsia.
Methods: This is a retrospective cohort study. Data was extracted from the record of patients who delivered between 2017 and 2020 and had chronic hypertension or, chronic hypertension with superimposed pre-eclampsia, gestational hypertension, or pre-eclampsia. Patients who received intravenous furosemide in the postpartum period were compared to those who did not. The groups were also analyzed for fetal growth restriction, and pregnancy outcomes comparing those who did receive furosemide and those who did not.
Results: The furosemide group had a statistically significant longer postpartum length of stay (p < 0.0001), required more antihypertensive medications (p < 0.0001), medication increases (p < 0.0001), and emergent blood pressure treatment (p < 0.0001), than the group who did not. There was no difference between groups in hospital readmission, or fetal growth restriction.
Conclusion: The postpartum length of stay and rates of readmission were not decreased in the group treated with intravenous furosemide. Future prospective studies that control for pregnancy comorbidities and severity of preeclampsia are needed to determine furosemide's effect on the volume status of the postpartum pre-eclamptic patient and determine its role in the treatment of these women.
